	Chapter 1

“Your twin dropped by today,” Aaron said casually.

My head snapped towards him, and my response was faster than I would have liked.

“Oh yeah?”

Growing up, Madison and I had always been competitive (it’s a twin thing) but over the years, I really thought I’d grown out of it. We weren’t, like, _close_ close, but we definitely got along, and the years of fighting for dominance were long behind us.

Or so I’d thought.

As soon as my housemate mentioned her, it was like I was twelve years old again. The years of tracking who was taller, who had better grades, who was faster, who had been the first to need a bra…it had all come rushing back.

But moreso.

In an instant, the old feeling hit me hard—the urge to demonstrate my superiority. When you’re a twin, you’re always being treated as a single entity. You’re not just yourself; you’re half of a set of twins. All of sudden, I needed to show Aaron that we were different.

That I was better.

It was weird; I don’t even _like_ Aaron. I mean, I like him, but not in that way. I’d been single for a while (although I’d just started seeing this new guy, Mike) and honestly, Aaron had never even crossed my radar.

There was nothing wrong with him, he just wasn’t my type. He was shorter than the kind of guy I usually go for, and a _total_ nerd.

And again, don’t get me wrong—there’s nothing wrong with that. I had no interest in fucking where I ate (so to speak) and living with a nerd was great for situations like when my computer had started acting weird a few weeks ago. After a few hours with Aaron, it was working better than ever.

But all of a sudden, I needed to know everything. I _needed_ to know what she’d said, what they’d done…

Not that it mattered. But I needed to know, all the same.

“She just wanted me to have a look at her computer,” my housemate replied. It was clear that he hadn’t given it two thoughts.

Part of me wanted to ask a thousand follow-up questions— _how long did she stay? What else did you talk about? What was she wearing? Did you like her outfit?_ —but I realized how ridiculous I was being, and kept my mouth closed.

It had taken me _years_ to grow out of this ridiculous competitiveness, and I wasn’t going to let it take hold of me again. And so I quashed my absurd impulse to cross-examine my housemate, nodded, and finished making my late-night snack.

Aaron watched me as I sat down at our kitchen table. I wasn’t looking at him, but I could feel his eyes burning into me. Part of me wanted to ask what the hell he thought he was doing, or snarkily remark that he should take a picture (it’d last longer), or just tell him to fuck off…but I didn’t.

We had a good housemate relationship, and I didn’t want to mess with that.

Plus…it was weird, but something told me that Madison would never have been this rude to him.

And I had to be better than my twin.

I shook my head. What a weird thought to have. I finished my toast, wished Aaron a good night, and popped onto my computer to see if there were any messages waiting for me in the company Slack. (I refuse to do any work stuff on my phone. You’ve got to have boundaries, right?)

There must have been a few, because when I next looked at the clock it was late—far later than I’d expected—and I took myself to bed, almost falling asleep before my head hit the pillow.

I had weird dreams all night. I dreamt that Madison and I were competing in a beauty pageant, then that we were on opposite teams in an episode of Family Feud (which made NO sense, but y’know. Dreams.)

The weird thing was that for both, Aaron was the judge. Actually no, the weirdest thing was that just before I woke up, I’d dreamt that we were pitted against each other on one of those reality dating shows. Like the Bachelor, but instead of fighting over a hot guy, it was Aaron.

It would have been funny, if it hadn’t felt so real.

I woke up late, and had to rush through my morning routine just to get into work just on time. When I got home that afternoon, Aaron was in the kitchen—almost like he was waiting for me—and he had that weird smile on his face again.

“What?” I said, letting my irritation creep into my voice.

“Your sister…” he said, and trailed off.

I felt it again, stronger than it had been the previous day. That competitive urge, that desire to prove that I was better than her.

This time, I decided not to fight it.

“What about her?” I asked, trying desperately to ask the question casually…which meant, of course, that it came out as forced and awkwardly as possible.

Aaron’s eyes flitted around my face, and I suddenly realized that I wasn’t wearing make-up (there hadn’t been time that morning) and my hair was a mess.

Madison’s hair was probably perfect.

“You guys are completely identical, right?”

Identical twins. Of _course_ we had to be identical—as if being a twin wasn’t bad enough.

It attracted some real creeps, as you can imagine. Guys who wanted to fuck both of us, or would dare us to make out or whatever. Not that we ever did, or ever _would_. I can’t think of anything that would gross me out more, and I assume that she felt the same way.

I’ve never had any issue with Aaron, but in that moment I hated him. It was probably an accident—there was no way he could’ve known about the sudden return of my competitive streak—but the way he’d phrased his question perfectly fueled my insecurities.

Of course we were identical. What was he suggesting? Had she looked better than me??

“Yeah,” I responded shortly, maintaining eye contact with my suddenly-infuriating housemate. My mouth was practically twitching with unasked queries until finally, I couldn’t hold myself back.

“Why??”

His answer was agonizingly slow. I felt like my entire body was vibrating, waiting for him to tell me.

“It’s just...well, she looked more, y’know.”

“What?”

“Maybe it was the top she was wearing, but she looked like she was...well, I’m not saying you’re small or anything like that, but...”

Aaron trailed off. Even he, socially clueless though he can often be, must have realized he’d gone too far.

You never, ever insult a girl’s boobs.

And you never, ever, _ever_ compare them to her sister’s.

In response, I shot him a glare so fierce that for a second I thought he was going to fall over backward. But then—as if he had no survival instinct at all—he kept going, stammering his way deeper into the hole he’d dug himself.

“I mean, it’s only because you never show any cleavage! She was…that’s all I…”

There were so, so many things I wanted to say or do to Aaron right then, but I took the moral high ground. I left the room, shooting him one final glare as I did. He didn’t say a word—it seemed he’d finally learned when the right moment was to shut up…although for a moment, I could’ve sworn I saw his half-smile return.

It was weird—Madison wasn’t normally the type to wear revealing clothing. She doesn’t dress like a nun or anything like that, but she was like me (exactly like me in this sense, I had to admit). We were a particularly busty pair, and while I know some girls dream of that, when you’ve lived through years of being leered at by strangers and having shop clerks staring wide-eyed at your chest as they serve you, you pretty quickly learn the value of covering up.

So why had she worn something cleavagey to drop a computer off?

I shook it off. Could’ve been any number of reasons. Maybe she was on her way to a hot date, or had just bought a new top that she wanted to ‘test out’ in a safe way (I couldn’t imagine anyone safer than Aaron for that). Or hell, maybe she had a crush on my housemate.

The flare of jealousy I felt at the thought surprised me. Like I said, I’ve never had even a hint of interest in Aaron. If Madison wanted him, as far as I was concerned, she could have him.

Just as long as, y’know, he still thought that I was the better twin. The smarter twin. The more pleasant twin.

The hotter twin.

I stood up from my bed, and crossed the room to have a good hard look at myself in the mirror.

I hated to admit it…but my clothes _were_ a little dowdy. I mean, I’m a professional, so I was dressed professionally and I’d done such a good job of hiding my bust that it practically looked like they weren’t even there.

Not that I wanted to look like a slut or anything like that, but…well, who wants to be the twin with the small tits?

Rifling through my wardrobe, I discovered that I only seemed to own two tops that showed any cleavage at _all_.

Maybe it was time to go clothes-shopping. I mean, I was overdue for a new outfit anyway.

I had to be better than my twin.

I _had_ to be better than my twin.

* * *

“Madison dropped by again today,” Aaron said, a few nights later.

I was tempted to throw him another glare, but I was too tired. The previous night it’d happened again—I’d lost a few hours watching YouTube videos on my computer, and gotten to bed way later than intended.

So instead I just raised one eyebrow and waited for him to continue.

He didn’t. He just sat there, this dumb grin on his face, like he was challenging me.

“What did she want this time?” I asked, rolling my eyes. I couldn’t tell who I was more annoyed with—him, for provoking me…or myself, for falling for it.

“She came by again today—she managed to download another virus, somehow.”

I chuckled. Madison was even more useless with tech as I was.

I had to be better than my twin.

“She ended up making some lunch as a thanks. Best Mexican I’ve ever had!”

My other eybrow joined my first. A part of me wondered if he was deliberately pushing my buttons. Our shared love of food was one of the main reasons Aaron and I had moved in together in the first place—Aaron’s a foodie, I love to cook…

Deliberate or not, it was working. I was suddenly hooked. I had to be better than my twin.

Who, I should point out, can barely boil water without setting the kitchen on fire.

Okay, so between work and spending time with Mike (who I _really_ liked), I hadn’t gotten a chance to cook anything lately. But that was going to change, starting immediately.

“Mexican? What’d she make?”

“She said she’d just learned some kind of new tortilla recipe. She raided the cupboards and half an hour later, we were eating the most amazing burritos I’ve ever had.”

“Oh yeah?”

“Yeah, it was great. Man, living with her when you were growing up must have been the best.”

Yeah—for her!

“You still like to cook, yeah?”

I nodded, gritting my teeth so hard I’d probably need dental work.

“You should get her to teach you some stuff,” Aaron grinned, and that did it.

I was suddenly so mad that I couldn’t even speak. Without a word, I got up, pulled out the mixing bowl, a wooden spoon, and some corn flour, and got to work.

Later that night when I went out with Mike, he was a little annoyed that I wasn’t hungry. He’d taken me to this restaurant, really excited to show it off to me. He knows how important food is to me.

All I needed to do was lean forward and throw my shoulders back, and his complaints died in his throat.

Side-effect of showing more cleavage: it’s suddenly much, much easier to keep your boyfriend happy. Who knew?

* * *

“Does your sister run?” Aaron asked out of the blue, about a week later. I was in the middle of removing the frittata from the oven—I’d cooked dinner every night since our conversation about it.

I was going to prove that I was a better cook than Madison if it was the last thing I did.

I had to be better than my twin.

“Mmmmm, I don’t think so,” I said. I’d almost dropped the tray when he spoke—there was something about Aaron talking about my sister that really got in my head. I was trying to sound nonchalant, but every fibre of my body was buzzing to hear what he was going to say next.

“When she made those burritos last week, I noticed her legs. She’s so fit! I figured she must run, because…well, damn.”

Aaron winked. “I have amazing legs too!” I wanted to scream, but I bit my tongue and focused on serving him dinner.

He’d offered to help, once or twice, but I’d told him to just sit there so he could really focus on the quality of the mal.

Back in the day, I probably would’ve had him do the dishes in exchange, but I knew Madison had done them after the burrito she’d made him (that he _still_ wouldn’t stop raving about) and so that wasn’t an option.

She’d set the bar, and it was up to me to beat it.

I had to be better than my twin.

“Nah,” I said. “She doesn’t run.”

I smiled, proud of my self-control for stopping there. Too proud, maybe, because I suddenly found myself adding a smug addendum.

“I do, though.”

“Oh really?”

“Uh huh.”

“I guess I never noticed,” Aaron said, leaning back and running his eyes up and down my body. “Because of the way you always cover them up.”

I was torn. On one hand, I wanted his attention on the amazing dish I’d just served him.

On the other hand, it was like Madison had stopped by herself and thrown down the gauntlet. Despite the fact that I really have _no_ interest in my housemate, I suddenly craved his eyes on my form. I wanted him to check me out…so he could compare me to my sister.

So that I could win.

So that I could be better than my twin.

After several minutes of leering, my housemate shrugged, and began eating. His response left me feeling strangely flat.

It’s funny—a few weeks ago, I would’ve felt like a lavicious comment about my body from Aaron was _completely_ inappropriate. Now, I couldn’t think of anything I wanted more.

After we finished eating—and I’d done the dishes and cleaned the kitchen—I returned to my room, and checked myself out in the mirror once more.

Sure enough, my legs (which I _knew_ were great) were completely covered up by the slacks I wore to work. So unless I started spending my time around the apartment in my panties (an idea so inappropriate it made me giggle), I’d have to pick up something that showed them off a little better.

I glanced at my bank statement with a worried look. I’d gone a bit overboard the last time I’d gone online shopping…but when the tops had arrived, they’d been _totally_ worth it. And Aaron, annoyingly, was right again—I didn’t own a single item of clothing that highlighted my legs.

_Screw it,_ I thought, opening up a new browser window. _What’s the point of running if no one sees the results?_

* * *

I made sure to be there the next time Madison came around.

The message had been weirdly hard to write. I mean, she was my sister—we IM’d each other all the time. But I’d wanted to get the phrasing just right, so I’d sat down at my computer to make sure that I was using the exact right tone…

…and the next thing I knew almost two hours had passed, and I was still staring at a blank text field.

I’d realized I was overthinking it, of course, and quickly shot off a message mentioning that I was going to be cooking, and that she could drop by if she wanted.

Somehow, I knew she would.

Her visit must have been on my mind, because that night I had a really weird dream about it. While I was cooking, Madison was hand-feeding Aaron, like she was a harem slave.

The weirdest thing was that because she looks exactly like me—in the dream, we were even wearing identical outfits—I sometimes couldn’t tell if it was me serving Aaron or her. I mean, that’s what this competitiveness thing comes down to, right? Trying to differentiate myself from my sister.

Nope. In the dream, it could have been either of us. We were like a completely interchangable matching set.

It was almost frustrating. Even to my own subconscious, we were identical. It was like I was buying into it, or something.

I had to be better than my twin.

I ended up taking the day off work to prepare for the dinner party. I mean, ‘dinner party’. It was me, Aaron, Madison, and Mike. I hadn’t had a chance to see him much lately—cooking for Aaron every day was eating up a bunch of my time and energy—so I thought this would be a great day to kill two birds with one stone.

God, I couldn’t _wait_ to see my sister’s face when she tried the feast I was preparing. I wanted to her to see—to _know_ —that I was better than her.

That I was better than my twin.

I had to be better than my twin.

Just as much as I was looking forward to my sister’s face, I wanted to see Aaron’s reaction to the meal. Unlike my sister, he was actually a foodie.

Would this finally prove to him once and for all who was the better twin?

As well as that, it was a great excuse to wear one of the more revealing outfits I’d bought. It showed off so much skin, it would’ve been downright slutty if it hadn’t been a formal outfit. The touch of class saved it, y’know?

It was a black dress that had big cut-out sections for my stomach, my sides, my back, and a plunging neckline that showed off plenty of cleavage. I say ‘cut-out sections’—most of the dress was cut out, really. There was a strip of fabric connecting the bottom half to the two strips that covered my breasts, and that was it.

I knew I could get away with it because the dress covered my legs from waist to toe…a glance, anyway. There were two waist-high slits, which meant it was easy enough to show my legs off.

And after all the extra jogging I’d been doing (what’s the point of showing off your legs if you aren’t in peak physical shape?), I absolutely intended to show them off.

Most people would host a dinner-party by cooking the same meal for everyone, but I’d gone above and beyond. I’d bought a _ridiculously_ expensive steak for Aaron, frog-legs for my sister (she’d spent like five days in Paris when she was a teenager, and would _not_ stop going on about it), and I’d even treated myself and made my favourite dish for myself—roasted eggplant, with mushroom asiago chicken on the side. I’d first had it in Italy, a visit that had completely transformed my life (and way raised my food standards!)

I just hoped someone would ask for a bite, because I’m not gonna lie—it was _amazing_.

It wasn’t until a few minutes before we were due to start that I realized I’d completely forgotten to make anything for Mike. Fortunately, I knew his eating habits, so I quickly threw together something I knew he was familiar with.

Madison was the first to arrive. Despite me telling her that I had food covered, she’d brought dessert—some elaborate cake thing. I could only hope that Aaron could see through her transparent ploy. She was such a show-off.

Mike was delighted to meet my sister. I found myself rolling my eyes as he made the standard series of twin jokes that we’d heard our entire lives. As if Madison was specifically trying to get under my skin, she flirted back—something Mike clearly enjoyed.

For some reason it didn’t really bother me, which in turn I think bothered her. So, y’know. In its own small way, that was a win.

I had to be better than my twin.

But the evening didn’t really really kick off until Aaron came home. I’d totally failed to mention to anyone that it was formal dress, so Aaron and Mike were just wearing their work outfits, while I was in a dress that wouldn’t have been out of place on the red carpet.

Where I had dressed up, Madison had practically dressed _down_. She was wearing a pair of Daisy Dukes, and a tan bikini top, that very much showed off her…assets. Her hair was down, and she’d worn flip-flops. The end result was halfway between a slutty girl-next-door look and just plain old trailer trash.

I’d hoped that Aaron wouldn’t like it, but then he goggled at the sight of her, and I cursed myself for not going slutty.

Why hadn’t I gone slutty? Now Madison was going to get all of Aaron’s attention.

I had to be better than my twin.

Everyone said hi, a strange feeling appeared in my gut as Madison kissed my housemate on the cheek, and then it was time for the food.

For all my effort…I honestly feel like I may as well have reheated a pizza for all the attention that anyone paid to the meal. Madison spent the whole evening alternately flirting with Mike and Aaron, and worst of all…Aaron flirted back.

I mean, I guess it would’ve been worse if Mike had returned her affection, but I just couldn’t believe the audacity of my sister. I was confident that she only wanted Aaron because I lived with him. She only wanted him because he was mine.

Well, I wasn’t going to let her win. Not this time. I quickly started hitting on my housemate as well. I could tell Mike didn’t really like it, but in the moment, that didn’t matter.

All that mattered was beating my sister.

Not to be outdone, I started to escalate things, and started rubbing Aaron’s leg with my foot. Mike had no idea what was happening, thank goodness. He made a pointed comment at one point about me ignoring him, but I barely noticed—my attention was completely on Aaron, while his seemed to be on my sister’s chest.

After everyone finished eating, Mike offered to help me clear the table. As soon as were alone in the kitchen, he sort of lost his cool. He was complaining about the oatmeal I’d served him (I have no idea why—I followed the instructions on the packet perfectly), the way I’d been behaving. Apparently he’d had to say my name four times to get my attention at one point.

I was starting to get antsy, leaving Aaron alone with my sister, so I knew I had to do whatever it took to get back in there. I kissed him, apologized, and told him that I’d obviously gotten carried away, and that I’d treat him better for the rest of the meal.

To seal the deal, I moved one of his hands to my exposed leg. Sure enough, he got this sort of glassy-horny look on my face, shot me a dumb grin, and said that it was okay.

As soon as we got back into the kitchen, I served up Madison’s stupid cake. Mike started to get pissy again because I had forgotten to bring him any—I thrust my slice at him, and moved around to offer Aaron a back massage.

Look…that might not have been the most emotionally sensitive move. My almost-boyfriend ended up leaving in a huff. Part of me felt that I should follow him and make it right…but that would have left Madison and Aaron alone again, and I couldn’t do that.

I just _couldn’t_.

Without Mike, I was able to spend the rest of the meal openly flirting with my housemate. I’ll tell you, I was pulling out _all_ the stops. I’ve never tried so hard with a guy before, not even one I like!

To my dismay, Madison matched me beat-for-beat. When I would laugh at one of Aaron’s inane observations; she’d practically bust a gut. I’d lean forward to show off my barely-contained tits; she would drop some cream on her breast, and slowly, laviciously lick it off.

I finally felt like I was getting the upper hand when my foot travelled all the way up Aaron’s legs, and I began massaging his bulge with my foot.

He just sat there, this smug look on his face, like he’d actually done something to deserve these two beautiful women buttering him up and hand-feeding him. I wanted to set the record straight, tell him that nope! He was just the lucky victim of two competitive sisters…but that would have been a point against me.

Anything that put Madison ahead was unacceptable. I had to be better than my twin.

The dessert that my twin had brought was okay, I guess, but from the way Aaron raved about it…Jesus.

I mean, okay, he didn’t actually _say_ anything, but I saw the smile on his face when Madison spooned it into his mouth, and it spoke more than words would have.

After we finished eating, I started to pretty heavily hint that Madison should leave. In return, she made a snide comment about me being ‘overdressed’ (I’m pretty sure she was just jealous that she hadn’t thought of wearing a skirt. I had to admit, those jean shorts looked good on her…but you can’t underestimate the suggestiveness of clothing that offers easy access.)

Then she left, and it was just Aaron and me. He again offered to do the dishes, but I thanked him and refused.

The one weird thing about the evening (besides what a slut my sister was inexplicably being) was when Aaron winked at me on his way to bed. I really hoped he wasn’t going to get the wrong idea—it could have been super awkward if he thought that I was into him.

This was just a little friendly competition, nothing more.

While I was cleaning up, Mike tried to call me. I let it go to voicemail—I just didn’t have the mental energy to deal with his jealousy.

I knew there was no way he’d understand. It was a twin thing.

It was well after midnight by the time I got to bed, but I was still pretty wired. I’d forgotten how much my sister could wind me up—just being around her can be so _stressful_. I ended up masturbating a few times before I got to bed, just to relieve the tension. The evening’s events kept playing in my head while I did, over and over—at first it was really distracting, but eventually I just went with it.


	Chapter 2

“Is Madison on some kind of special diet?”

The mention of my sister was enough to immediately tense me up. I’d been so relaxed all day—I’d left work early to stop by this little specialty food store (they carried a spice I’d been reading about that I wanted to try) and once I got home, I’d spent a few hours cooking.

I found cooking a great way to unwind, but it turns out ‘Aaron talking about my sister’ was an even better way to undo it, so I turned to see what he was talking about.

“What is it this time?” I answered, trying to hide the frustration in my voice. We’d been eating in silence—Aaron hadn’t even complimented the meal—when he’d hit me with the question.

“Your sister came by today,” he said. Aaron works from home, in IT—he does a lot of contract work for the government, stuff like that. On the rare occasion I’d been in his room, his huge monitors had been almost overwhelming.

“Uh huh?”

“And I’ve got to tell you, she has one _great_ -tasting pussy.”

“That’s not because of diet!” I blurted out before I could stop myself. “That’s just…I mean, I’m sure I taste just as good.”

“Yeah,” Aaron said, sounding wholly unconvinced. “Probably.” I wanted to punch him, but I knew my sister would never do something like that, so I restrained myself.

I had to be better than my twin.

“I don’t know about that…I mean, you’ve got understand. She tasted _amazing_.”

He pushed the steak away, and I slowly unclenched my fists. I’d been getting up early each morning to jog, plus I’d barely slept the night before—I’d been looking at recipe sites on my computer when I’d noticed it was later than I’d expected, and then after finally getting to sleep I’d had a series of _such_ weird dreams.

“Sorry,” Aaron said with a shrug. “I just don’t think you can compete.”

It was like he’d found the perfect combination of words to trigger something in my brain. The moment the challenge left his mouth, I knew that I was going to convince him that my pussy tasted better than Madison’s.

If it was the last thing I ever did, I’d make him admit that my juices tasted better than my twin’s.

Without a word, I slowly moved one finger between my legs. I took a moment to play with myself, to ensure that I was nice and wet, then pulled my sticky finger out for him to taste.

That arrogant grin of his crept back over his face as he opened his mouth, extended his tongue, and licked the pale fluid off my finger.

At first I thought he liked it, because he grabbed my hand and moved my entire finger into his mouth, sucking on it while he stared me in the eyes. But just as I thought I’d won for sure, he shook his head.

“Mmmm…” he said. “I’m sorry, but…—“

“Wait!” I said, cutting him off. I knew that I didn’t want to hear the rest of his sentence. “Did you taste hers from, uh…the source?”

A blush spread over my face at the question, but Aaron didn’t seem bothered. As he nodded, I suddenly remembered—my dream last night had been about my housemate going down on my sister.

Or possibly going down on…me. My sister and I had really started to blur together in my dreams. _That_ probably wasn’t healthy.

With a sigh, I moved everything on the table to the side, and Aaron lifted me onto the table. Sitting in front of him, I slowly spread my legs, glad that I’d changed into such a short skirt as soon as I’d gotten home.

Just like the skirt I’d been wearing in the dream.

Aaron leaned forward—there was nothing but air between his mouth and my pussy. He’d mentioned a few days ago how cool he thought it was that Madison didn’t wear a bra, and so in an effort to outdo her, I’d stopped wearing underwear entirely.

I had to be better than my twin. I _had_ to be better than my twin.

“Wow,” he said with a sigh, like this was something he’d been looking forward to. “You’ve got a really beautiful cunt.”

I was practically glowing with pride at his words. He’s never been the most loquacious guy, but since my competitive streak had so firmly returned, it felt like hadn’t so much as thanked me for anything.

To hear him describe my privates as _beautiful_ felt amazing, especially because I couldn’t help but interpret it as ‘more beautiful than your sister’s’.

But then his next sentence just as swiftly deflated me.

“Of course, Madison shaves hers…”

Before I could respond he leaned forward and pressed his tongue to my pussy-lips. I sat there with bated breath as he thoroughly explored my pussy with his mouth—licking, tonguing my clit, burrowing his wet muscle as deep into my hole as he could.

Tasting. Tasting, and comparing me to my sister.

After a minute or two, I was beginning to feel quite squirmy. Like I said, I’m not actually attracted to Aaron, but I think any gal enjoys having her pussy worshipped by a nice warm tongue.

“Hmm,” he said, coming up for air.

“What!?” I snapped. The entire time Aaron had been going down on me, I’d been desperate to know what he thought, how I stacked up against my sister.

I had to be better than my twin.

“Do I taste as good as Madison!?”

“Oh, I totally forgot about that,” Aaron replied casually, and the desire to punch him returned stronger than ever. “I was just thinking, it’s always so interesting…”

“What is?”

“The difference between twins.”

My housemate was between my thighs. I was tempted to close them and suffocate him, but I knew that wasn’t a good idea.

Besides, I’m sure it wasn’t something my sister would do.

“How?” Being compared to Madison always put me on edge, and it didn’t sound like Aaron was about to say something nice. “How are we different?”

“Your sister cums really easily,” Aaron mentioned. “Anyway, this time I’m going to focus on the taste.”

I’ve honestly never had trouble cumming. Even though we’d only been seeing each other for a month or so, Mike was always able to get me off several times whenever we had sex. So to hear that my sister was the same way was simultaneously unsurprising and deeply, deeply disturbing.

I mean, who would even want to think of what their sibling is like in bed?

But I knew I had to be better than my twin, and so—Aaron’s words ringing in my ear—I decided to pull out all the stops.

I closed my eyes and my mind flitted between a series of erotic thoughts. The hot make-up sex I’d had with Mike after the dinner party, the first porn I’d found, my favorite erotica, the fantasies I’d had since I was a teen…soon my clit was throbbing with arousal, and Aaron was still tasting me when my first orgasm wracked my body.

“Oops,” I said, trying to act coy as I panted with pleasure (not an easy feat). “Sorry about that, buddy.”

Aaron seemed completely unfazed. “No problem,” he replied casually. “When Madison cums she’s _much_ louder.”

“Oh really?” I asked, and reached out to push his head back between my legs.

I had to be better than my twin.

My housemate spent more than hour that night ‘tasting’ me, his mouth pressed against my mound, his tongue getting me off again and again and again, as I tried to beat my twin in volume, expressiveness, duration, anything I could think of. By the time we were done, I needed Aaron to know without a shadow of a doubt— _I_ was the twin who came fastest, loudest, strongest, and most frequently.

I had to be better than my twin. I had to be better than my twin. I had to be better than my twin.

Finally, after almost a dozen increasingly loud orgasms, I told him I was exhausted and needed to stop.

“Okay,” he said simply, but I understood what he really meant.

Madison had been able to go for longer.

* * *

Mike broke up with me four days later. I’d been spending so much time letting Aaron taste me, and I think Mike had sensed that he’d become less of a priority in my life. When I wasn’t cooking or cleaning, I was sitting spreadeagled on the table (or on the bed, so that Aaron could be more comfortable—see, it’s _that_ kind of thoughtfulness that I know for sure Madison doesn’t possess) while my housemate’s mouth was buried between my legs.

After my fifth orgasm on the second day, I’d finally remembered to ask Aaron how I tasted compared to my sister—he’d said that it wouldn’t be fair to compare, because it was so late in the day (and Madison had come by quite early)…but that he _did_ remember enjoying the sight of her boobs bouncing.

I’d stripped off and let him tongue me to several more orgasms, squirming naked on the kitchen table as he tasted my shaved cunt, and in the process…completely forgotten that I was meant to be out with my boyfriend. I’d apologized by text as I came around Aaron’s tongue, but then been too distracted to read Mike’s reply.

The next morning, I’d woken Aaron up and asked him to taste me again. He’d been more than happy to oblige—after bringing me to climax a few more times, he said it had been too long since he’d gone down on my sister to really remember what she tasted like, and that he’d need to try again when he was more awake.

Aaron ended up tasting me two or three times a day for the rest of the week, and so when I finally made it to a date with Mike, I was both sexually and physically exhausted. According to Aaron, Madison was able to hold all kinds of positions longer than I was, and…well, I’m obviously not one to back down from a challenge.

I had to be better than my twin.

Mike had immediately picked up on my low energy, and when he had asked if I even wanted to be _with_ him any more, I just shook my head. He went really quiet at that—I probably should’ve said something, but I just didn’t have it in me.

It was weird—our breakup was almost exactly like it’d been in a dream I’d had the previous night. Maybe I was a little bit psychic?

Mike drove me home, thanked me for my honesty, and I went back upstairs to see if Aaron was hungry.

For food _or_ for pussy.

I passed Madison in the hall—she threw me a smug smile, but kept on walking, so I quickly made my way into the apartment to find Aaron reclining on the couch, a huge shit-eating grin on his face.

Oh, no. What had she done now?

“Wow,” he said. “That twin of yours…”

“What?” I snapped. “Did she cure cancer or something?”

I don’t know what it was—the second Aaron mentioned my sister, it was like the primal hunting part of my brain switched on. My heart-rate increased, my ears perked up, and adrenaline started pumping through my body.

I suddenly felt energized, like I could do anything. If Madison _had_ cured cancer, I felt like I could march straight into a lab and work out a better, stronger, faster cure myself. I’d do whatever it took to be better than my twin.

Whatever it took.

“I invited her over so I could compare your tastes,” he said, ignoring my snide comments. “And she mentioned that she gives the best blowjobs in the city.”

“Oh, bullshit,” I said, unable to contain myself.

If there’s one thing I pride myself on, it’s giving head. I’m no slut, but believe me—you show me a man that I can’t get off with my mouth, I’ll show you a gay man.

Actually, no. I could get a gay man off. This was one area in which I was _very_ confident in my abilities.

And I’d do whatever it took to be better than my twin.

My blood was hot as I knelt before my housemate and unzipped his pants. I noticed a hint of Madison’s lipstick on his shaft, and cursed myself for not wearing any makeup. I normally did, around the apartment, but since I’d only been going out with Mike I hadn’t bothered.

Taking Aaron’s (quite attractive, if I’m being honest) cock into my mouth, I gave it everything I had. I stared at him, doe-eyed, as my tongue swirled around his head. One of my hands wrapped around the base of his shaft, while the other gently fondled his balls.

Closing my lips, I applied just enough suction to make him groan, before starting to slowly bob my head up and down, running my lips all the way up and down his erection. I made a slight gagging sound—slightly before I even felt my gag-reflex kick in, if I’m being honest—and began to deepthroat him.

As I held his cock deep in my throat, I realized that _this_ , going down on my housemate, had been part of my break-up dream as well. Weird.

Soon enough, the combination of my lips, tongue, direct eye-contact, and probably just the fact that I was his incredibly hot housemate were enough to set him off. Madison must have _just_ finished, because it took a little longer for Aaron to cum than I was expecting, but when he did cum it was a thick load.

I opened my mouth to show it to him, let a tiny bit dribble onto my face, then swallowed the rest. Like I said, I definitely know what makes good head.

“Well?” I asked, standing with pride. “What do you have to say to that?”

“Pretty good,” he said, and I narrowed my eyes.

“Yeah?”

“I mean, your sister was naked. And she kissed me beforehand—made it really personal, y’know? And she plays with herself when she’s getting a guy off, and…”

I sat there silently fuming as Aaron continued his list. Part of me wanted to strip off, throw him back onto the couch, and show off again…but I wanted time to prepare for my next opportunity.

And so I just glared as he finished his list. I continued to glare as he left the room. And when I got myself off that night, I mentally pictured my housemate, just so I could continue to glare at him.

That’s definitely all it was.

* * *

Throughout this whole thing, my sister and I were totally civil to each other. It wasn’t like we were fighting over the same man or anything—I really had _no_ interest in Aaron whatsoever.

I just hate it when I’m not the best at something.

I’d do whatever it took to be better than my twin.

One Saturday she dropped by when I was giving Aaron head (it had somehow become a standard part of our day, like me cooking for him, or him bringing me off with his mouth), and I have to admit—it felt good to see the look of surprise on her face as I shuddered in orgasm, my face immaculately made-up, giving one of the best blowjobs in the history of oral sex.

Of course, Aaron didn’t follow it up with a ‘great job, that was way better than your sister’s’ (as amazing as that would have been). To my relief, he didn’t say anything like he had been recently (like “Well yeah, but your sister’s been doing tongue exercises, so it’s not really fair to compare…”)

He just nodded his approval, and invited Madison to follow him to the bedroom.

At first, Madison had made excuses for why she was coming over so often. She wanted to get Aaron to look at her computer again, or she’d forgotten her bra. Never mind the fact that she didn’t even think to bring her laptop, or that neither of us had worn a bra in weeks.

Eventually, however, she dropped the ruse. She’d come over, nod hello, make out with Aaron for a bit, then go into his room.

It had started as just blowjobs, I was sure of that. I’m not too proud to admit, I’d often sit with my ear against the door, trying to see if I could work out any tricks she was using.

But that Saturday morning, I started to suspect that they were doing more than just going down on each other.

It was the moaning that gave it away. Moaning with a cock in your mouth is certainly possible, but for obvious reasons it produces quite a muffled sound.

My sister’s moans were long, and loud. He hadn’t been lying about her volume. And from my position, the only thing muffling them was the door—I could clearly hear her moaning Aaron’s name, complimenting his girth, his speed, and how good he felt inside her.

The words sounded incredibly familiar, and it wasn’t until her third or fourth orgasm that I realized—I’d had a dream last night where she’d said the exact same thing.

And in my dream, they’d been fucking.

For some reason, my clit throbbed at the idea of Aaron fucking my sister. It was probably just the fact that I knew I’d be fucking him next.

I’d do whatever it took to be better than my twin.

Whatever. It. Took.

I listened through Madison’s screaming, moaning, and breathless orgasms, and when they were done, I scurried to the couch (still naked—I’d been so preoccupied listening to them, I had forgotten to redress) to sit casually, like I hadn’t just been listening to their copulation.

Madison gave me a friendly nod, but I knew what it meant. It meant “I win, bitch.”

Okay, maybe I had mentally added the ‘bitch’ part, but I knew she was gloating.

It’s a twin thing.

And as soon as she left, I got up and made my way into Aaron’s bedroom to see if I could do any better.

Annoying as Aaron could be, I had to admit: his stamina was impressive. From the sounds of it, he’d cum inside my sister two or three times—on top of the blowjob I’d already given him.

Two or three times…which, of course, I knew I’d have to match.

I’d do whatever it took to be better than my twin.

I’ll never forget the first time my housemate fucked me. I was already soaking wet—I wasn’t attracted to my housemate _or_ my sister (gross!) but there’s something unavoidably sexy about listening to people have sex. It’s like real-life porn, y’know?

And as soon as I’d worked out what was happening, I’d known that I’d have to follow it up. So I’d played with myself, listening to my twin’s moans, Aaron’s pants. Once or twice I’d thought I’d heard him say something—something like ‘your twin would…’ or ‘your sister always…’, but that must have been wishful thinking.

By the time they were done, I was as wet as I could ever remember being, and despite the fact that I was only doing this to show Madison who was the better twin, I had to admit: feeling a cock— _any_ cock—inside me would be an extremely welcome sensation.

Aaron was laying on his bed, this smug look on his face. His computer monitor was on, showing a big list of data; I was too far away to read exactly what it was, but I could make out some numbers, and beside each was a checkmark or a red cross. The numbers were mostly 1’s and 2’s, but there was a pair of 3’s at the top, green checkmarks besides each of them.

When I walked in, his cock began to rise. It was coated in what I assumed was a mix of his cum and my sister’s juices (something I did _not_ want to think about), but it looked just as good as it always did.

Since Mike and I had broken up, I hadn’t even thought about dating. I’m not normally a hyper-sexual creature, but spending so much time naked around Aaron, so much time researching better ways to blow him, making out with him in every room of the house, and reading countless articles on the oral arts of pleasing your man (not that he was my man)…yeah, sex was pretty constantly at the forefront of my mind.

The oral sex that Aaron had been giving me every day helped, I’m not going to lie. I’d sort of forgotten we were doing that to see if my sister or I tasted better (something I’d _still_ not gotten a clear answer on)—it had just become a daily part of the routine.

I’d wake up, brush my teeth, go to work, come home, and Aaron would lick me out for a while.

But I had pretty close to zero attraction to my housemate, so as much as I appreciated his very talented tongue, I was still horny most of the time. I’d get myself off each and every night. I’m as straight as they come, so I liked to imagine cock when I masturbated.

And since Aaron’s cock was the only one I’d seen in a while, my mind would inevitably come back to that. Makes sense, right?

Right?

So when Aaron gestured for me to clean him off with my mouth, I felt like I should object. I’d tasted my housemate’s cum (and cock) a thousand times, of course but…his dick had my sister’s arousal smeared all over it.

That wasn’t right. Right?

But I was so turned on, and the cock I’d spent so much time thinking about when I got off was right there, and even through my momentary confusion, one thing was clear:

I’d do whatever it took to be better than my twin. And something told me that my sister wouldn’t hesitate to suck my juices off Aaron’s cock if our positions were reversed.

And so I crawled towards him on the bed and began licking it clean.

Now, I’ve gotten pretty good at getting Aaron off with my mouth. As I slurped Madison’s juices off my housemate’s cock, playing with my own pussy all the while, I knew that I could have made him cum. I could have swallowed it down, then drooled some onto my chest, and watched him get hard as I licked it off my own tits.

After all, I’d done it so many times before.

As my tongue lovingly worshipped Aaron’s cock, it was tempting. I didn’t _need_ to fuck him, I reasoned.

And then he said it.

“God that’s hot,” he moaned. My entire body lit up at the compliment. “Your mouth is so good, it almost reminds me of fucking your sister.”

Fire appeared in my eyes, and without another moment of hesitation I removed his cock from my mouth, positioned myself above my housemate’s postrate body, and accepted his challenge.

We both moaned as my slick folds spread, allowing Aaron’s wet cock to enter me.

It felt _amazing_.

I mean, it would have felt pretty great no matter who it was; I don’t want you thinking I was _into_ Aaron or anything like that.

No, I was just into the feeling of a long, thick cock inside me. It just happened to be Aaron’s.

Not that I could let him know that, of course.

“Oh god, Aaron, you’re so goood…” I moaned loudly, putting on a show that I knew he’d like. “Fuck. Fuck! I’ve never felt anything like this before in my life.”

My housemate didn’t say anything in return, just beamed up at me. I bet he was pretty damn happy with himself—fucking two identical twin sisters in the same afternoon, one after another.

He really was the luckiest man in the world, to have stumbled into the middle of our weird little sibling rivalry.

“Yess, fuck me!” I exclaimed. “Oh, fuck, Aaron…you make me feel like a _woman_!”

One thing I’d noticed, listening to Madison, was that she didn’t really do much in the way of dirty talk. This, I figured, would give me the edge.

I’d do whatever it took to be better than my twin.

“Your cock is so big,” I purred. “Oh yes, I want to feel it inside of me forever. It fills me up so _good_!”

I knew how much Aaron liked making women cum, so I reached between my legs, and stroked my needy clit.

“I’m going to cum,” I panted. “Fuck! Aaron…I’m going to cum while you’re inside me. Oh, yes…I’m going to cum going to cum going to cuummmm!!”

I’d do anything to be better than my twin. Whatever it took.

I convulsed in orgasm on Aaron’s hardness, as he reached behind and gave my ass a quick, hard slap.

“Yes, daddy!” I cried out. One of my ex-boyfriends before Mike had insisted I call him ‘daddy’ while we fuck. I’ve no idea why, but I figured that there was a chance Aaron would enjoy it as well.

By the way his cock pulsed inside me, I think my guess was correct.

I came several more times before I felt Aaron unloading inside me. After that, we took a brief break while I prepared him some food (and home-made beer; he’d told me that Madison was thinking of taking up homebrewing, so I’d made sure to beat her to it) and then I fucked him to orgasm twice more that night.

Each time I did, I’d sit beside him with a smile, trying to hide how desperately I wanted to hear him say it.

But he never did. Instead, he’d just slap me on the ass and throw me a smug look.

It was infuriating as well…and ensured that I was going to try harder.

I’d do whatever it took to be better than my twin.

After that, I fucked him daily—sometimes several times. But there are only so many hours in the day, and I guess something had to give. After that long Saturday of fucking, oral sex stopped being a daily thing. I’d still blow him at meals from time to time, but we just didn’t have the time to keep going down on each other at the rate that we had been.

And I was now getting _more_ than enough orgasms from riding my housemate’s cock.

But no matter how often we fucked, no matter how good I was (and believe me—I know I was _great_ ) he never said it.

“Wow. You’re a better fuck than your sister.”

Eight words. Eight words would all it would take, but would he give them to me? No!

And so I just had to keep trying harder and harder and harder.

But whatever I did, it felt like Madison could always match it. Whatever positions I tried, however dirty I talked…even when I managed to squirt, soaking the bed and surprising even myself, he wouldn’t give it to me.

Eight words. Hell, I’d take seven! The ‘wow’ was a bonus.

“You’re better than your sister.”

It would only have taken five to make me happy, really!

As the months went by, as I fucked Aaron in every room of the house, as I let him cum inside me multiple times a day, it was starting to drive me mad. I’d started using what limited spare time I had to study up—kegel exercises, lessons in stripping, everything I could think of. I even took an online photography course, to make sure that my nudes were better than the ones I knew my sister sent him.

But none of it seemed to make a difference.

I needed to know. I needed to know exactly what it was that Madison was doing so much better than me.

So one day, I opened the door to watch while they hooked up.

He was going down on her, which hit me with an unexpected burst of jealousy. It wasn’t like he _never_ went down on me, but it had definitely been a whole lot less frequent since we’d started fucking.

Was that why he clearly thought she was better? Despite us being completely identical, was he more attracted to her? Attracted enough to go down on her?

Aaron’s face was buried between my sister’s thighs, so he didn’t notice me entering. Madison did, however—her eyes widened in shocked, then the corners of her mouth curled up, and I knew.

It was on.

“Oh Aaron,” she cried, and I watched my twin sister’s entire body clench as she came. “Fuck…you’re amaaaazing.”

I returned her cold smile, and began stripping off. Not that I was really wearing much—Aaron had mentioned once that it was a pity I couldn’t pull off a schoolgirl outfit like my sister did, so I’d maxed out my credit card and bought the sluttiest schoolgirl costumes I could find.

It’s weird—until then, my sister had never come around in a schoolgirl outfit, and she hadn’t been wearing one in any the nudes I’d seen on Aaron’s huge monitors. But as soon as she saw me in one, she practically turned green, and since then Madison had been wearing one every time she came around.

I stripped out of a plaid micro-skirt, undid the single button on my white ‘button-up’ shirt, but kept the school shoes on. I say ‘shoes’—they were 5-inch heels, really.

But Aaron liked them. And that was all that mattered.

As I undressed, I checked out my sister—this was, after all, the first time I’d actually seen her naked since we were teenagers. I was surprised to see that her breasts _were_ slightly bigger than mine, but I knew my legs were more shapely. All that running had quickly paid off.

When my housemate came up for air, he saw me standing there naked, and the smirk returned to his face.

“Well well well…” he said. “What have we got here?”

“Once and for all,” I said, in my best ‘little girl’ voice—Aaron had told me that Madison’s ability to do slutty-cute was off the charts, and I was trying my hardest to outdo her. “You’re gonna have to decide which of us is better in bed.”

There was a pause as he thought about it, but he eventually nodded.

“Let the games,” he said with a pompous flourish that made me want to slap him, “…begin.”

He pointed at his crotch, and there was a brief pause as Madison and I stared at each other, until we both dove for his cock.

“No scratching!” he quickly added, and Madison and I took it down a notch. It didn’t take us long to find a rhythm—I’d suck on his shaft while she took his balls into her mouth, or we’d each just take one side of his cock.

The whole while we were panting and moaning, making the best porn noises that we could.

I was the first to cum—the whole situation was so bizarrely erotic, it only took me a few minutes to bring myself off, but Madison quickly followed suit. The room was soon filled with the smell of two girls in heat, and the sexiest sounds we knew how to make.

When I sensed Aaron’s orgasm was approaching, I tried to ensure that I had my lips wrapped around the end of his cock, but apparently my sister had learned the warning signs as well, and she pushed me away at the last second.

His head popped out of my mouth and started spurting, covering the two of us in his seed.

“Oh, Aaron…” she moaned, reaching up and coating her fingers in his cum, before licking them off laviciously.

“So much _cum_ …” I said, raising the bar by licking his seed directly off my sister’s face.

We stopped just short of making out, and when all the cum was gone, turned to face Aaron. I fell to my knees (what guy doesn’t like a naked, busty woman kneeling in front of him?) and Madison quickly joined him.

The sight of two naked twins in front of him, submissively looking to him for instruction quickly had the desired effect, and Aaron was soon hard again.

I drooled at the sight of his erection—I’d like to claim that it was purely for show, but things had started to get a little mixed up in my brain.

Aaron’s cock had given me _so_ many orgasms; it was hard not to get a little aroused when I saw it.

“Girls...” he said, a thoughtful look on his face. “You must know how hard this is for me—you’re easily the two best fucks I’ve ever had in my life, and I can’t just decide who’s better...”

“You have to,” I little girl’d at him, and after another long pause, he nodded.

“Okay,” he said, “but please, one at a time.”

For reasons unknown, he chose Madison to go first. I sat outside the bedroom and played with myself for almost an hour while I listened to them fucking. It wasn’t anything new, of course—my sister had even gotten pretty good at dirty talk (I don’t know if Aaron had told her how much he liked it, or if she’d somehow overheard me and my housemate fucking) but I had an ace up my sleeve, and I was delighted when my snooping confirmed that it hadn’t occurred to her as well.

Maybe I _was_ better than my sister.

Madison must have cum at least a dozen times while I was listening. When she was done, she stumbled past me bleary-eyed. I watched her collapse onto the couch, cum dripping out of her pussy as she did, and went into Aaron’s room.

He was laying naked on the bed, looking pretty exhausted himself. Perhaps that would have frightened a less confident woman, but I knew that I could get him energised, get him hard, and then give him the best fuck of his life.

I’d found some lingerie while he’d been taking Madison, over and over, and my heart leapt at the smile he gave me when he saw it. I knew I was competing with what was essentially an identical version of myself, so I’d really gone all out—the bra emphasized my tits to the point where they managed to look even bigger than Madison’s, and my red thong made sure that the effects that my many hours of running had on my ass were readily apparent.

As I slowly slipped the thong down my legs (I had decided to keep the bra on, at least for my first few orgasms, just so I could show him the contrast between how hard I cum with and without nipple stimulation) he plumped up, and I slowly lowered myself onto his member.

I knew the lingerie was hot, but that was just a starter. My plan was so, so much more than that.

“I want you to knock me up,” I hissed into his ear.

“What?” he said, shocked. I couldn’t help but smile as his eyes filled with lust.

Brilliant, right? I guess I can’t take all the credit—the idea had actually come to me in a dream. I’d dreamt about being pregnant to Aaron, bearing his child...it’s a primal thing. It’s the reason sex exists, after all.

Men exist to get women pregnant, women exist to get knocked up by their man.

Not that Aaron was my man, of course.

And so even though the idea doesn’t particularly do anything for me (Aaron’s just my housemate, y’know?) I somehow knew that he would find it hot as hell.

I’d do anything to be better than my twin.

“I haven’t been taking the pill,” I said, in my sexy-cute little girl voice. Aaron groaned at my words. “I want you to knock me up, daddy. I want your cum inside me, finding its way to my fertile womb.”

“Oh, _fuck_ …”

The first of what I knew would be many orgasms rippled across my body, but when I had recovered, I continued my erotic onslaught.

“Fill me up with your seed. Please. I want your sperm to impregnate me. I want to be knocked up with your baby.”

I reached down, moving one of his hands to my tits.

“These tits will be so bloated and full of milk.”

I moved his other hand to my stomach.

“My tummy will start to grow, daddy. Every time you fuck me, you’ll know that I’m yours. That my baby is growing inside of me, that you’ve marked me as my property…”

My stomach clenched as I came again. I had to admit, I was starting to turn even myself on.

“Fuck, Aaron…I’m going to be pregnant. For you. I’m going to be so, so huge.”

Without warning, Aaron flipped me over, and I reached out to steady myself. He fucked me from behind, as I sat on his bed on all fours.

“In just a few months, I’m going to be your knocked-up little slut.”

Aaron grabbed my hair with one hand, and used the other to hold my waist. My tits were bouncing everywhere as he began to thrust into me faster and faster, and I could feel his balls slapping against my legs.

I reached behind me and grabbed his scrotum, caressing his testes gently as he pounded into me.

“Do you know what’s inside of these?” I panted. “Millions of sperm. Millions upon millions of potential babies…that will soon be surging into me, filling me up. Knocking me up. Making you mine…”

“I’m going to knock you up,” he gasped, and I nodded frantically, my eyes rolling back with pleasure.

“Do it!” I gasped. “Please…”

Aaron thrust into me and let out a loud groan as he came, pumping his seed deep into me. I could feel a powerful orgasm of my own hit—the kind of orgasm I only had when I felt his cum splashing inside me.

“Yessss…” I moaned, impressing myself. I couldn’t remember the last time Aaron had cum that quickly—especially after a bout with my sister.

When we’d both come down from our respective orgasms, Aaron shot me a funny look.

“Was that true?” he said, and I reluctantly shook my head.

“I just wanted to show you that I was a better fuck than my sister.”

_Was I?_ I wanted to ask, but I knew Aaron didn’t like needy women.

“So you’ve been taking your pill?”

“Yeah…” I nodded, not sure where he was going with this.

“Madison!” he called out, and my sister opened the door, like she’d been sitting directly outside listening to us fuck. Which I think we all knew she had been.

“Are you going to choose between us?” I asked nervously. “Are you finally going to tell us who won?”

“Even better,” Aaron said, beaming.

Madison and I gave him identical skeptical looks, but it did nothing to dim his smile.

“Here’s the plan,” he said. “I want both of you to stop taking birth control immediately.”

My eyes widened, but I didn’t say anything.

I had to be better than my twin.

I’d do whatever it took to be better than my twin.

I’d do anything to be better than my twin.

_Anything._

“I’m going to knock both you up,” he said with a smile. I nodded frantically, and could see Madison doing the same next to me. “And to decide who’s better, you or your sister…”

“Yes?” I asked, after the silence got too long for me to bear.

“The better twin will be…whoever bears twins with me.”

My eyes flashed competitively. “Genius,” I said.

“Absolutely brilliant,” my sister nodded.

“This is the best idea you’ve ever had.”

“I can’t _wait_ to bear your children,” Madison said.

“You’ll be _such_ a good father.”

“That’s all for now,” Aaron said, getting up and heading to his large monitor. I saw that the numbers at the top had each changed to 4.

Computer stuff. I doubt I’ll ever understand it.

Madison and I—both as naked as the day we’d been born together—were left on his bed, and I turned to my sister with a smile. Suddenly, all the competitiveness, all the rivalry I’d felt for so long dissipated, and I held out my hand.

Until we knew who had twins, there was no possible way of competing with her, so why not embrace the new closeness we’d inevitably feel?

Aaron glanced at us, looking extremely satisfied as Madison lay her head on my chest, then turned her face up to look at me. I made eye-contact with her and smiled.

“We’re going to be mommies together...” she whispered, and I nodded in reply.

“Of course,” I added, “my kids will be better...”

	Chapter 3

The second I saw that look in Aaron’s eyes, I was suspicious.

“What?” I asked, and when he just smiled and ignored me, I pushed harder. “What??”

“Oh,” he said, a casual smile upon his face. “Nothing…”

“What is it?” I pressed, and when he continued to ignore me, that smug grin upon his face, I pulled out the big guns.

Aaron is my housemate. He’s also the father of my unborn child. He’s also the, uh, the father of my identical twin’s unborn child…she lives with us too.

Yeah, it’s a long story.

See, Madison and I have always been super competitive. It really escalated in the last six months or so—when I found out that Madison was sleeping with Aaron, I just had to do whatever I could to compete. I started trying to match her however I could—I shaved my pussy for the first time, I made sure that my orgasms were longer, louder…and over the last little while, I’ve spent hours reading “sex tips” and “sex manuals” and everything like that I could find.

But the look in Aaron’s eyes told me—my twin had managed to find something that I hadn’t done yet.

And so I did what I always did when I wanted to get my way. I pulled out my huge, swollen tits, and pouted.

“Aaron,” I said, a slight whine in my voice, “I’m so full of milk…but unless you tell me what’s up, I can’t let you milk me…”

Practically salivating at the sight of my huge, oh-so-sensitive nipples, Aaron looked conflicted. I knew that he wanted to taste the milk as it poured out of my teats, but he hated giving in so easily.

“I’ll tell you what,” he said. “I’ll suck your tits dry, and tell you while _you_ suck _me_ dry.”

I agreed immediately, as he knew I would, and my eyes rolled back with pleasure as Aaron’s mouth latched onto my tits and started sucking the milk out of me. There was something so primal, so sexy about being milked like this, and it was particularly sexy to be sucked dry by a lover.

Sometimes, when Aaron was in the mood, he’d get me and Madison to do this to each other. I tried to tell myself that those moments weren’t sexual, but I could imagine how it would look from Aaron’s point of view—two curvy, naked twins, each pregnant with his child, sucking the milk out of each other…

After he was done he switched to the other breast, and my fingers wandered down to my cunt. A side-effect of pregnancy that you don’t always hear about is the hormones—I could go from laughing to crying in an instant, of course, but more than that…I was constantly, constantly horny. Unless Aaron was able to find and fuck me, it was rare for me to go more than a few hours without having to get myself off, and from the sounds I heard coming from Madison when she locked herself in the bathroom, her pregnancy was having much the same effect.

I ran out of milk all too soon (though I knew that by the next day, they’d again be swollen to the point of overflowing) and in a movement that I’m sure was much sexier when I hadn’t had a belly full of baby, got down on my knees in front of Aaron.

For some reason, perhaps as a result of the pregnancy hormones, I’d started to find giving head deeply erotic. I mean, I’d been giving head to Aaron for months, but it hadn’t really been a sexual thing before.

From my end. I imagine he’d found it pretty sexual, especially because I’d let him cum anywhere he wanted. My face, my tits, my mouth, my meal… _anywhere_.

But ever since the second trimester, something about giving head was just so _sexy_.

Maybe it was the submissiveness of it…there’s something hot about kneeling in front of your man, focusing entirely on his pleasure. Not that Aaron was my man, of course, but it wasn’t like I was dating anyone else. Who’s going to go out with a heavily pregnant woman who lives with her twin sister and the father of their children?

So yeah, like it or not, I was stuck with Aaron.

And for some reason…I’d kind of started to like it.

I moaned as I took my housemate’s cock into my mouth. Though it was a challenge, I was proud of the fact that I managed to refrain from cumming until I was swallowing his load down my throat. I wouldn’t want the distraction of an orgasm causing me to give Aaron anything less than 100%.

I bet Madison doesn’t consider that.

I’d do anything to be better than my twin.

I’d do anything for Aaron’s approval.

As I came down from my orgasm, my mind finally absorbed what my housemate had told me as I blew him.

“Madison let me take her ass last night,” he’d said simply, and I had nodded, so focused on his orgasm and my own that though I’d heard the words, I hadn’t processed them.

I’ve never known Aaron to flag, not even slightly—he manages to take care of two nymphomanic twins, and as if that wasn’t enough, he even brings other girls home pretty regularly. Madison and I share a bed, and when we hear the sounds of pleasure coming from Aaron’s room, we’ll wake up, and get off as quietly as we can to the sound of our housemate pleasing yet another woman.

A part of me is terrified by the idea of him impregnating one of these hookups, forcing us to stretch our already-limited housing situation to fit another huge woman, but if he asked us to, we would.

We’d probably rush over each other to do it, each of us desperate to demonstrate that we were the more accommodating twin.

I’d do anything for Aaron’s approval.

And so while I’m sure that he would have been happy to take my ass for the first time that night, I wasn’t ready for it, mentally or physically. I was still wrapping my head around the fact that yes, I could take all of Aaron’s cock inside me without any risk of damaging the baby—the idea of having him stretch out another of my holes was sexy, sure, but I’d need some time to think about it first. (As well as make sure that I cleaned up.)

Aaron understood and, instead, quite happily deposited another load of baby-batter inside my hungry cunt. As I lay there afterwards, enjoying the feeling of fullness that I always got when Aaron deposited his seed inside of me, I was tempted to get up and give him another blow-job, just for the sheer fun of it, but exhaustion quickly hit me, and I drifted off to sleep.

* * *

I dreamt that night of what it would be like when Aaron took my ass. He would, we both knew—there was no way that I could let my sister beat me. I had to be the better twin.

I just had to.

Pictures flowed through my head—Aaron, kneeling behind me, beaming at me as he slowly split my ass-cheeks…my pregnant body, wracked with orgasm as he came deep in my ass…my sister watching with a proud smile as Aaron took my rear entrance.

That was the image that stuck with me when I woke up the next morning. It was just a dream, of course, but it had felt so real.

And I’d woken up so, so horny.

I carefully got up, and entered Aaron’s room. When Madison had moved in with us, we’d done something dumb. We’d told Aaron that he had to choose which of us shared a room with him.

That’s the thing about being competitive—it can be pretty hard to switch off.

Madison had claimed that since my room was already full of all my stuff, I should stay where I am. I countered by letting her know that Aaron and I had gotten so used to each other’s presence, it made more sense for me to be the one to share space with him.

Things had started to get heated, until eventually Aaron held up his hands, and we fell silent. He’d explained that if we were going to fight about it, Madison would just have to move into my room, and he’d have the bedroom to himself. At least until we learned to share.

Looking back, that doesn’t seem like the best solution, but it really seemed to make sense at the time.

If I wasn’t in the middle of an ongoing contest with Madison to see who could complain to Aaron less*, I probably would’ve done something about it. Sometimes he’d just be so, so biased towards my sister in these little competitions of ours—it was so blatantly unfair.

*which I was winning, by the way.

So when I entered Aaron’s bedroom, dripping wet, ready to beg him to take my ass (he loves it when Madison and I beg), I am not going to lie, I was a little annoyed to see that Madison had beat me to it. She was on all fours, her pregnant belly and huge tits swinging back and forth as Aaron slowly, carefully, but very firmly fucked her ass.

“God, Aaron,” she moaned. “You’re so big.”

It was _totally_ unfair, right? Aaron had already fucked her ass! It was my turn!

But I didn’t want to be ungrateful, so I just quietly made my way to his office chair, took a seat, and leaned back to watch.

Madison looked like she was having a good time, but she always did. It was hard to tell how much was performance—ever since we were kids, she’s been the sort who’d do anything for attention—and how much of it was genuine pleasure. If it was even half as good as the dream I’d just had, I’d guess it was mostly the latter.

Aaron shot me a grin, and I beamed back at him.

I’d do anything for Aaron’s approval.

He’s an okay housemate. Not the worst I’ve ever had, but also not the best. (Although he was better than Madison, that was for sure—she _never_ did the dishes, and sometimes I’d catch her blowing Aaron when it was my night)

But I’ve just had so many orgasms around his cock, I guess it’s a instinctive thing. Sometimes I’d get a rush of endorphins just at the sight of his erection, or from the way he’d smile at me.

And I think he’ll be a good father to our kids.

But mostly I smiled at hime because I knew that if I could keep him in a good mood, he’d probably fuck my ass next.

His brow was coated in sweat, and he closed his eyes to continue fucking my twin. I was tempted to reach between my legs and get off at the real-life porno in progress in front of me, but I’d never had anal sex before, and I figured the whole process would be easier if I kept myself turned on.

Something on Aaron’s computer caught my eye, and I turned to see that he had the program open that I always saw from across the room. Sitting this close actually allowed me to read what was on the screen, and it took me a moment to realize why it had grabbed my attention—my name was there, along with Madison’s. We both had green checkmarks listed, along with a few lines.

“Stage 1-4 complete. Stage 5 in progress.”

“What’s stage 5?” I asked, and Aaron’s eyes widened as he realized what I was reading.

“Don’t look at that!” he warned. Madison opened her eyes as well.

“Yeah, sis…” she gasped, her voice thick with lust. “What kind of a girlfriend would go snooping around a guy’s stuff like that?”

My eyes widened.

Madison wouldn’t, that’s for sure.

“I’m not Aaron’s girlfriend,” I shot back. “Neither of us are!”

It was really important that I made that clear. I wasn’t into Aaron, but if my sister suddenly started treating him like she was his girlfriend, I knew myself well enough to recognize that I’d get competitive about it, and insist that he was my boyfriend.

And god, who knew how _that_ would end.

Madison didn’t respond. My twin’s eyes were closed, her mind once more subsumed by pleasure. I turned away from the computer, and resolved not to pry.

But I watched my sister cum, her ass wrapped around my housemate’s glorious cock, my mind kept niggling away at the strange program. While I’d been scanning it to see what had caught my eye, I’d read some other names, all with different numbers listed beside them. Angela, level 1. Taylor, level 2. Priscilla, level 3. None of them had a checkmarks beside their names—instead, there had been a cross, and “FAILED” in big letters.

It looked like Aaron was cumming too. I licked my lips as I watched, when a thought struck me.

One of the girls Aaron had brought home was called Priscilla, now that I’d thought about it. She seemed like a typical rich brat, as so many Priscillas were. They’d had long, loud sex a few times, and then—like many of the girls Aaron brought over—we’d never seen her again.

Why was he tracking the girls he had sex with on his computer?

My sister was finally done, and—as I knew Aaron would like—I begged to take my ass. After a few minutes of teasing he obliged, and half an hour later he was pumping his seed deep within my rectum, as I came again and again around his cock.

I’m always a little hazy after sex, so it was several hours before I remembered what I’d seen.

“What does stage 5 mean?” I asked him again, as I served him lunch while Madison knelt in front of him, sucking his cock.

Yeah, that’s right. Aaron would never actually _say_ it, but I’m pretty sure he likes my cooking better. I’m always in charge of lunch on Fridays, while Madison is delegated to blowjob duty.

It’s nice to have the occasional clear win, y’know?

“God,” Madison said, pulling Aaron’s erection out of her mouth to chide me. “Just leave it _alone_ , would you?”

I wanted to shoot her a glare, but I didn’t want Aaron to see. Instead, I carefully got to my knees, and joined her in fellating my housemate. I knew he liked it when our tongues touched around his cock.

I even reached out to squeeze her breast. I probably could have milked her through her top, but I was worried that would distract her from giving Aaron the best blowjob possible.

I’d do anything for Aaron’s approval.

“No,” Aaron said thoughtfully. “That’s a valid question. You two are in the fifth month of pregnancy, right?”

“Seventh,” I corrected, before taking Aaron’s cock as deep into my throat as I could.

“Right,” he said with a laugh. “Looks like I’ll have to update the tracking software.”

When she was sure Aaron wasn’t watching, Madison shot me a smug glare. It had been a pretty stupid mistake on my half, I guess. I don’t know what I’d thought it was—something sinister, maybe? Instead, Aaron was just using some advanced software to make sure our babies were safe.

But…why had it been two months out of date? And why were the other women listed?

Unable to resist my curiosity, I let Madison take the head of his dick into her mouth and continued the line of questioning.

“Why was Priscilla on there?”

Aaron’s eyes darted around the room at that one, but it was only a few seconds before he responded.

“She asked me to track her pregnancy too,” he said. “And I was, until…well, I couldn’t any more.”

My cheeks flushed as I realized what he was saying.

Well, great. I’d really put my foot in it.

“Sorry,” I said in a small voice. He smiled down at me, and ruffled my hair.

“That’s okay,” he said kindly. “We can’t all be good at everything.”

God, the self-satisfied look on Madison’s eyes as she swallowed down Aaron’s cum. I could’ve killed her.

I didn’t think about the software again until I was cleaning Aaron’s room a few days later (he’d said that he thought Madison was better at tidying up AND scrubbing floors than I would, even while pregnant. Obviously there was no way I could let _that_ shit stand) when I was cleaning off his keyboard, and accidentally unlocked his screen.

There it was again. My name and Madison’s, both listed as being at level 5.

Aaron may have been a smart guy, but clearly he wasn’t great at record-keeping. I clicked through and updated us both to level 7.

What a strange system. You’d expect it to go by trimesters, or at least call them months, but nope!

I glanced through the rest of the list. Aaron’s friends sure had poor luck with pregnancy. It looked like Madison and I were the only two who’d gotten past level 4 with green checkmarks beside our names, although right at the bottom of the list were a few checkmarks besides early-stage names. Carla, Merideth—both level 1. Matilda, Angela, Sarah—level 2.

I sure hoped that they’d be okay.

That night, as I was checking my email, something strange happened.

I don’t really consider myself a, like, tech addict. Aaron doesn’t like seeing me or Madison on our phones—he says we look like ‘zombies’—so we generally only use those for phonecalls; for everything else, we’ll use our computers directly.

It’s probably good for us, honestly—you know how you can accidentally pour a bunch of time into social media? Well, when you’re sitting up at a desk (and especially when you’re seven months pregnant), that’s _much_ less likely.

Not that it never happens, though. Every now and then—maybe every few months or so—I’ll find myself in a Wikipedia hole, and I’ll suddenly notice that _hours_ have passed without me noticing.

That night, I accidentally pulled an all-nighter.

It was _so weird_. I wasn’t even doing anything interesting! I had, like, five emails from work. (They’d moved me to remote when my belly had gotten large enough, which was great—it meant I could spend even more time demonstrating to Aaron that I was the better twin.)

I’d gotten through four of them when the next thing I knew, it was eight-thirty am. My stomach was grumbling, my eyes were sore, my back was _killing me_ (even more than it had been for the last few months of pregnancy), and more than anything I was just…confused as hell.

Like, the time I’d pulled an all-nighter watching Tiger King, I’d known what I was doing. It had been stupid, yes, but I’d _known_ that it was stupid, and I’d done it anyway.

This time, I’d been checking emails, and all of a sudden the time had just…gone.

I turned around from my desk—Madison had been on our bed on her laptop when I sat down. She was still there, in the exact same position, a completely dead look on her face.

All of a sudden she came back to life and looked at me strangely.

“What _time_ is it?” she croaked, looking aghast when I told her. “Jesus…I told myself I was just going to read _one_ Reddit thread.”

“I know, right?” I said, trying to laugh it off. I sat beside her on the bed, trying to decide whether to have a nap or grab a snack, when tiredness overcame me and made the decision on my behalf.

Madison and I woke up around twelve, at almost the exact same time. I’d had a series of strange, erotic dreams—all of which starred my _sister_ , weirdly—and so when I woke up, I didn’t immediately realize that I wasn’t still in one.

“What are you doing?” my sister asked, and I silenced her by moving my lips to hers. Her eyes widened in shock, but as my tongue slipped between her lips, she began caressing it with hers, while moving her hands down my body.

It felt like we were making out for an hour, gently groping and exploring each other’s pregnant bodies, before I finally realized this was no longer a dream, and pulled back.

“Uh…sorry about that.”

“It’s okay,” Madison replied calmly, leaning forward to give me a soft peck. “I’m going to go see if Aaron is up.”

Aaron was awake but not up—he had a girl over. My twin later told me that she’d seemed surprised to be brought breakfast in bed by a pregnant, mostly-naked woman, especially since Madison hadn’t batted an eyelid when she’d found Aaron balls-deep inside the woman—“Sarah”, her name was. She couldn’t have been the same Sarah as I’d seen on the computer, however; after leaving Aaron’s room, I found her in the kitchen smoking a cigarette.

“Hi,” I said.

“Hi again,” she said, looking at me nervously. She obviously thought I was Madison, despite the _clear_ differences between us. Madison’s tits were bigger, my legs were more toned, and I was wearing a red negligee, whereas my sister was wearing a matching blue one.

We chatted for a few minutes, before she left, muttering something about it being too fucking weird.

Pity. She’d seemed nice.

A few minutes later, Aaron came storming out of his room.

“What did you do to my computer??” he asked, his eyes flashing with anger. I’d never seen him so worked up.

It took me a moment to work out what he was talking about—I was still pretty hazy from lack of sleep. “Oh, I updated the pregnancy tracker,” I said with a yawn. “It was still out of date.”

Aaron’s mouth gaped at my response. “Have you…have you been on your computer since then?”

“Uh huh,” I nodded. “Checked my emails last night.”

I didn’t mention that I’d then apparently spent more than twelve hours staring slackjawed at my screen. I didn’t want to give him any more ammunition to compare me to my sister.

Although by all accounts, she’d done the same thing.

“And you’re…okay?”

“Yes,” I said, rolling my eyes. “I know I’m seven months pregnant—better than you, apparently—but I am capable of checking emails without suspicion.”

Aaron continued to stare at me for a few moments, before nodding.

“Cool,” he said, his half-grin returning. “That’s…that’s good.”

I raised one eyebrow.

“Thanks,” I said, turning away from my housemate’s strange behaviour and focusing my attention on the coffee-pot that I’d just brewed for Sarah. “I know I’m not meant to drink caffeine while I’m pregnant, but…god, I don’t know how else I’m going to stay awake.”

“You can if you want,” Aaron said, that smug smile of his firmly on his face. “I mean, Madison wouldn’t. But you can.”
