It wasn’t like she immediately declared her love for him – she’d been perfectly clear that she was developing feelings for him and had a suspicion they would become more significant – but she did start to act more like she was pursuing a genuine long-term relationship with him.</p><p>Despite knowing that we were potentially playing with fire, I couldn’t help but find it all rather exciting. In truth, it enhanced what had already been exciting. As you know, I rather enjoy watching Naomi get ready for a date with Derek. Well, that got so much hotter when I knew her date was about more than getting fucked. Watching her carefully select a dress or style her hair was so much more arousing.</p><p>Every little relationship milestone between her and Derek felt exceptionally arousing. I know it might sound crazy, but I couldn’t help but get enormously aroused every step of the way.</p><p>We reached one of those milestones on a Friday night. I was watching Naomi get ready for a date with Derek. She’d gone with a more casual look than usual, though she was still gorgeous in a short, colorful sundress and a pair of flats. Her hair was wavy and she wore almost no makeup. She still looked breathtaking, of course.</p><p>“What’s with all the stuff?” I asked as I watched Naomi pack a larger bag than usual.</p><p>“I’m spending the night at Derek’s,” she said.</p><p>She hadn’t yet done that. She’d come home awfully late a few times, but this was the first time she’d be coming home the next morning. Not surprisingly, I found the idea enormously exciting.</p><p>“Really?” I said, though my voice was more lusty than questioning.</p><p>Naomi turned and smiled at me. “You like that, don’t you?”</p><p>It had been almost two months since she’d started dating Derek and we’d both long since come to terms with the idea that I absolutely loved her being with another guy.</p><p>“I love it,” I said.</p><p>I did love it. There was a part of me that was a little sad, too. It wasn’t often that Naomi and I spent the night in separate beds. Still, if it had to happen, this was unquestionably the best way for it to happen.</p><p>Naomi packed a change of clothes along and said, “He’s taking me out to brunch in the morning. I’ll come home after that, okay?”</p><p>“Of course,” I said.</p><p>“Oh, and there’s one more thing,” Naomi said as she moved closer.</p><p>I could see a hint of concern in her eyes. Whatever she was about to say, she wasn’t sure how I was going to react. There was a time when it would have worried me. I didn’t feel worried, though. Mostly, I felt intrigued.</p><p>Naomi took my hands in hers and said, “Derek and I are going to start having unprotected sex.”</p><p>As you might imagine, I was hit with an immediate and incredible sense of lust as she shared her very naughty little detail.</p><p>“He got tested last week and he’s clean, of course. I’m the only woman he’s sleeping with, and since I’m on the pill we both decided it was time,” Naomi continued.</p><p>Naomi reached down and played with my cock, which had grown half hard without being touched. We hadn’t really talked about Derek cumming inside her, but obviously I loved the idea. It was so sexy.</p><p>As her fingers stroked me through my pants, Naomi leaned in and whispered, “You like that another man is going to cum inside me tonight, don’t you?”</p><p>I swear, I almost came. It was the way she delivered the naughty line and the exceptional lust in her voice that thrilled me beyond words.</p><p>“I do,” I whispered in response. “I can’t even tell you how much I like it.”</p><p>“Don’t worry,” Naomi said softly. “You don’t have to tell me, baby. I know what my husband likes. I know what you need.”</p><p>It had been obvious for quite some time that Naomi was on board with my fantasy, but that was the first time she’d talked like that about it, like she was considering my needs along with hers as her relationship with Derek evolved. It made me think that part of her desire to have Derek cum inside her was because she knew I’d find it exceptionally arousing.</p><p>“You’re welcome to masturbate tonight, but it might be even more exciting for you if you wait until tomorrow. I think we could have some very naughty fun together,” Naomi said as she released my cock and gathered her things.</p><p>“That sounds wonderful,” I said, though I honestly wasn’t sure if I could resist masturbating. I knew I’d have trouble thinking about anything other than Naomi and Derek having unprotected sex, likely more than once.</p><p>Naomi then gave me a long kiss and departed for her boyfriend’s house.</p><p><br></p><p>I won’t lie, it was a long night. I somehow managed to hold off on masturbating, though I did play with my cock a little bit here and there. It just felt too good. I’d close my eyes and imagine Derek fucking my wife without a barrier between them. I’d imagine him filling her with cum as Naomi wrapped her legs around him and urged him to release his seed inside her.</p><p>I didn’t cum, though. I wanted to save that for when Naomi got home. I wanted whatever fun she had in mind to be as arousing as possible.</p><p>It was a little after 11 a.m. when I received a message from Naomi. It was a picture of her and Derek at brunch. They were sitting next to each other with their food in front of them and they were sharing a kiss while she took a selfie.</p><p>There was so much about it that triggered my particular brand of cuckold lust. They looked very much like a real couple on a date, which they were. The kiss was flirty and fun. They’d chosen to sit next to each other instead of across from each other, which people often do when they’re first falling for each other. They just wanted to be close.</p><p>I wondered if Naomi had taken the picture specifically so she could send it to me, or if she’d snapped it because she wanted a memento of a really nice date with Derek and it just happened to carry the extra benefit of being useful for teasing and arousing me. I also couldn’t help but wonder if she had Derek’s cum inside her as they sat at brunch. There was absolutely nothing to indicate that, of course, but I still thought about it.</p><p>All of if left me rather aroused, which must have been her overall purpose in sending the picture. She wanted to tease her husband (in a good way) while she was on a date with her boyfriend. It honestly felt perfect.</p><p>It also fueled by my fantasies and desires for the next three hours, as Naomi didn’t get home until a little after 2 p.m. She came through the door with a gorgeous smile on her face and a beautiful bounce in her step.</p><p>As had happened so often since she started dating Derek, Naomi jumped into my arms and kissed me after getting home. I loved that she seemed so overjoyed to see me. It always helped to reassure that we weren’t destroying our marriage and that we might have been strengthening it.</p><p>“How was your night?” Naomi asked.</p><p>“Torturous,” I answered, “but in the best way possible. How was yours?”</p><p>“Incredible in every way,” she answered before kissing me again. “My morning was incredible too. Everything was incredible.”</p><p>I hadn’t seen her in such a good mood in a long time. It was wonderful.</p><p>“Come,” she said while walking towards the bedroom. “I take it that you managed not to masturbate?”</p><p>“That’s right,” I said as we walked into the bedroom.</p><p>Naomi hopped into the bed and spread her legs. She pulled up here dress and revealed a pair of blue cotton panties with an obvious wet spot.</p><p>“Is that?” I asked.</p><p>“It is,” she said.</p><p>Derek’s cum was leaking out of her. For a few moments I couldn’t do anything but stare at it. It was genuinely mesmerizing.</p><p>“It’s beautiful, isn’t it?” Naomi said.</p><p>I looked up at her and saw the broad, beautiful smile on my wife’s face. I saw that she really did think it was beautiful that her boyfriend had cum inside her.</p><p>“The sex was even better, honey,” Naomi continued. “I came even harder knowing that he was going to cum inside me. I can’t really explain it, but it felt so much better. It was the same way for him.”</p><p>I snapped out of my lust-fueled state and moved on top of my wife. I was still dressed, but only because I wanted to prolong the pleasure a bit. I wanted to hear a little about the fun she’d had, because I knew once I plunged into her pussy I wasn’t going to last long.</p><p>“So I guess he came inside you more than once,” I said before leaning down and kissing Naomi’s neck.</p><p>Her hand moved to the back of my head and ran through my hair as she moaned. Her legs wrapped gently around me.</p><p>“Three times last night and twice today,” Naomi said, “and each time it was incredible.”</p><p>I was always amazed and aroused at the volume of sex Naomi had with Derek. She and I had never really gone more than twice in a day, and they routinely fucked three or four times in a single evening.</p><p>This was unquestionably hotter. They hadn’t just had sex five times. Derek had cum inside my wife five times. He’d released five loads of his semen inside her body. Contemplating it as I kissed her neck and rubbed my crotch into hers was an arousing experience on par with few I’d ever had before.</p><p>“He wants me to start spending the night more often, honey,” Naomi said before pulling my lips to hers for a long tongue kiss.</p><p>She wasn’t asking permission. She was telling me that she was going to be spending more time with Derek because she knew I’d find it arousing.</p><p>“How often?” I asked between kisses.</p><p>Naomi’s hands grasped my ass and she gave it a good squeeze. She closed her legs tighter around me and we dry humped like teenagers. In the moment it felt impossibly sexy.</p><p>“At least once a week,” Naomi answered me.</p><p>At first I felt an uncomfortable sense of jealousy. Once a week seemed like a lot, and she was clearly leaving the door open for it to be more than once a week. At the same time, it was exceptionally hot.</p><p>“Is that going to be okay?” Naomi asked as she unzipped my pants and reached inside them to pull out my cock. “Are you going to be okay with me spending a lot more time with my boyfriend?”</p><p>Despite the fact that she’d been dating Derek for two months, it never ceased to arouse me when she called him her boyfriend. Every time it was thrilling. I always took that as a strong confirmation of just how much of a cuckold I was.</p><p>I groaned as she stroked my cock. It felt impossibly good. “Yes, that’s okay. It’s wonderful, in fact,” I answered.</p><p>Naomi released my cock for a moment to pull aside her panties. We kissed as she wrapped her fingers around my erection once more. She rubbed the head around the entrance to her body.</p><p>“Do you want to fuck me?” she asked before kissing me again. She wanted me to have to wait to answer. She wanted to tease me a little more, both with her tongue dancing in my mouth and the way she was rubbing me over her perfect, wet, cum-filled pussy.</p><p>“Yes, desperately,” I answered when Naomi released my lips from hers.</p><p>“Even though you know I’m filled with another man’s cum?” she asked.</p><p>Naomi knew that would only make me want to fuck her more. She was playing with me, and she was doing it perfectly.</p><p>“Especially because you’re filled with another man’s cum,” I answered. It was the absolute truth. I was exceedingly turned on because she had Derek’s cum inside her. I wanted to feel it. I wanted sloppy seconds.</p><p>“You don’t mind using his cum as lube?” Naomi asked.</p><p>It felt like such a naughty thing to say. It was spectacularly vivid, that’s for sure. I couldn’t help but imagine her pussy being completely filled with Derek’s cum as my cock slid inside her. I imagined her cunt welcoming me and my dick swimming in another man’s seed as I fucked her.</p><p>“I want to,” I answered. There was no point in being anything other than completely honest. I wanted to use another man’s cum as lube while I fucked my wife.</p><p>Naomi smiled, guided my cock inside her wet pussy, and kissed me. Despite my insane sense of lust, I took my time. I let my cock bottom out in my wife’s cum-filled cunt. I enjoyed the obvious sensation of someone else’s semen inside her. There was no question it was different. I could absolutely feel it, and the idea that it was Derek’s load only made it that much hotter.</p><p>It was far wetter than usual, which was no surprise. There was less friction, too, but that didn’t stop it from being intensely pleasurable. I was so worked up that I knew it wasn’t going to be long before I came.</p><p>“Fuck, Naomi, your pussy feels so good,” I said between low, lusty moans.</p><p>“You mean my cum-filled pussy?” she asked as her hands grasped my ass and pulled me closer. “Add your cum to his, honey. Add your cum to Derek’s,” she encouraged me.</p><p>At that point I couldn’t hold back. At Naomi’s urging I came inside her. The notion that I was the second man to cum inside her that day was more than enough to make it a genuinely mind-bending orgasm.</p><p>When it was over my mind was awash in pure cuckold joy. It was almost perfect. There was just one little thing that bothered me.</p><p>“You didn’t cum, did you?” I asked.</p><p>Naomi smiled as she ran her fingers through my hair. “I’ve already had four orgasms today, honey. I don’t need another.” She kissed me softly.</p><p>I believed her, but it didn’t stop me from feeling a little insecure. Derek had made her cum four times. I hadn’t made her cum once. It deepened my sense of being a cuckold, but it did worry me a little.</p><p>Despite that worry, I was overjoyed with the experience. Naomi’s first unprotected sex with Derek had been a resounding success and I’d enjoyed a great orgasm as a result. All told, I couldn’t wait for where our journey was going to take us next.</p>
