She took his hand and looked up at her boyfriend to see a smile on his face.</p><p>“Are you satisfied?” Bella asked.</p><p>“Satisfied with what?” Zack replied.</p><p>“With us…with this…with where our relationship has gone,” she clarified.</p><p>Zack stopped and turned towards her with a concerned look on his face. “Bella, are you unsatisfied? Are you unhappy? You can tell me if you are. I’ll do whatever it takes to make you happy.”</p><p>Bella couldn’t help but laugh. “Zack, no, it’s not that. I’m happy. I’ve never been happier, in fact. I’m asking because I genuinely want to know if you’re satisfied.”</p><p>“Why wouldn’t I be?” Zack asked.</p><p>Bella took his hand and they continued down the sidewalk. “Well, because our relationship is different than most. I mean, I have sex with Luke more than I have sex with you. A lot more, in fact.”</p><p>Zack stopped again. “Bella, honestly, you can tell me if you’re thinking of leaving me. I’d prefer it if you just told me now, in fact. I’m all in on this relationship – as in, I want to be with you forever – and I’d prefer not to commit further if you’re planning on dumping me for Luke.”</p><p>Bella couldn’t tell if she’d completely failed to convey that she was genuinely concerned for Zack’s happiness or if he was being obstinate for some reason she couldn’t discern. Her frustration couldn’t help but emerge when she responded to him.</p><p>“Okay, I’m sorry for being so clumsy about this,” Bella said. “But I need you to believe me when I say I’m happy with you, Zack. It’s actually a little bit unfair for you to assume that I’m unhappy when all I’m doing is trying to see if you’re actually happy in a relationship where your girlfriend is having more sex with her ex-boyfriend than she’s having with you. You understand that this is an unusual arrangement, right?”</p><p>Bella watched an array of emotions wash over Zack’s face and she felt terrible. He was clearly feeling a little bit insecure – or more than a little bit, perhaps – and she’d made it worse by scolding him in public.</p><p>“I’m sorry,” Bella said as she reached up to caress her boyfriend’s face. “I shouldn’t be so short with you. You’re a wonderful boyfriend, Zack. You happily packed up and moved with me. You’re happily living in my mom’s house while we save money. You’re happily letting me sleep with my ex-boyfriend. I have no right to get frustrated with you.”</p><p>“Yes, you do,” Zack replied. “You were asking a perfectly reasonable question and I was being insecure. I don’t know why, but the moment you asked me if I was satisfied I just assumed you were about to tell me that you’re not satisfied. I guess I just feel like because I can’t satisfy you sexually that at some point you’re going to decide that you’d rather just be with someone that can, that there’s no point in having me around.”</p><p>Bella opened her mouth to stay something, but Zack kept going.</p><p>“But I am satisfied,” he said. “I’m happy. Like you, I’m as happy as I’ve ever been. I understand why that might seem kind of crazy to you – you’re not wrong that our relationship is different than most – but I’m happy. I’m really, really happy.”</p><p>Bella believed him, in part because it would have been an insane thing to lie about and in part because she saw nothing in his eyes to indicate even a hint of dishonesty. Bella’s fingers snaked behind his neck and she pulled Zack’s lips to hers for a kiss. She intended for it to be a soft-but-lingering kiss – the sort you might share on a public street – but it quickly evolved into something far more appropriate for the bedroom.</p><p>“Wow,” Zack said when their lips finally parted.</p><p>Bella smiled as she felt his erection press into her stomach. “Yeah, that was something, wasn’t it?”</p><p>Zack nodded.</p><p>“Can I ask you something?” Bella asked. “If I told you that I wanted to stop by Luke’s bar and fuck him before we went to dinner, would you be okay with that?”</p><p>“Yes,” Zack answered without hesitation.</p><p>Bella studied his face for a few moments in search of some indication that he wasn’t telling the truth. She still marveled at the idea that Zack was genuinely okay with her putting her lust for Luke before his needs, but it seemed that he was.</p><p>“What if I gave you a choice?” she asked. “You could fuck me in the restaurant bathroom or I could fuck Luke, but you’d be the one to make the decision. What would you choose?”</p><p>Zack didn’t have an immediate answer for that question. Bella smiled and kissed his neck as he considered the question. When she moaned Zack gently pushed his crotch forward, rubbing his stiff dick against her body.</p><p>“I’d choose to fuck you,” he finally answered.</p><p>“Why did it take so long to answer?” Bella asked.</p><p>“Because I kept telling myself that the right choice was to let you fuck Luke,” Zack replied. “But then you kissed my neck and you moaned and all I could think about was how badly I wanted to fuck you and how good it would feel to be inside you.”</p><p>Bella stepped back and smiled at the tent in Zack’s pants. She took his hand and led him to a bench so they could sit while his erection faded. “Do you really think it was the right choice?” she asked. “To let me fuck Luke, I mean.”</p><p>“That’s the choice you would make, isn’t it?” Zack said.</p><p>Bella expected to see pain on his face as he posed the question, but there was none. Instead, there was a brief flash of arousal in his eyes, leading her to believe that some part of Zack liked the idea that his girlfriend would choose to fuck someone else.</p><p>“Yes, it is,” she admitted. “It’s not because you’re bad in bed, or anything.”</p><p>“It’s because Luke is better,” Zack said.</p><p>He was right, but Bella felt bad saying it out loud. Instead, she held his hand and rested her head on his shoulder.</p><p>“I love you, Bella,” Zack said. “I suppose it would be accurate to say that I’m still wrapping my head around how our relationship has changed since we moved to Colorado, but I’m genuinely happier than I was before we moved.”</p><p>“Me too,” Bella replied as she looked up and gave Zack a kiss on the cheek.</p><p>“The craziest part is that this all really turns me on,” Zack said. “Like, really turns me on. I mean, if I’m being honest, I’d probably find it just as satisfying – or satisfying in a different way, I suppose – if you fucked Luke, went to dinner with me, spent the night teasing me, and then let me go down on you when we got home, especially if I got to masturbate while I was going down on you. I don’t know, maybe I’d actually find that more satisfying because I’d spend a few hours in a highly aroused state.”</p><p>“Maybe you’d be even more aroused if I fucked Luke, went to dinner with you, and then dragged you to the restaurant bathroom to eat my pussy for a few minutes. Maybe I’d even suck your cock for a little bit to drive you absolutely mad with desire before tucking you back into your pants and leading you back to the table,” Bella said as she gleefully played along with Zack’s idea.</p><p>Zack smiled at her and Bella glanced up and down the street before reaching between his legs and grasping his cock through his pants as her lips found his for another long, wonderfully lusty kiss.</p><p>“How long until our reservation?” she asked.</p><p>Zack pulled out his phone to check the time and answered, “Ten minutes.”</p><p>“You wait here until your boner goes down. Then go ahead to the restaurant and get seated at our table,” Bella said.</p><p>“Where are you going?” Zack asked, though he must have known the answer.</p><p>“I’m going to fuck Luke,” she said. Bella gave him a kiss on the cheek, got up, and headed for Luke’s bar. Her pussy tingled with desire and she nearly broke out into a run to get there quicker. She wanted Luke’s cock inside her, though not entirely because fucking him was so much fun. She wanted to play with Zack, too. She wanted to spend the night teasing him. She wanted to give him the sort of orgasm he deserved, and it seemed like fucking her ex-boyfriend and then toying with her boyfriend all night would give Zack that kind of orgasm.</p><p>Zack took a sip from the glass of cold water he’d just poured himself and smiled as he leaned against the kitchen counter. The taste of Bella’s pussy was fresh in his mouth after spending ten solid minutes between her legs offering his tongue for her pleasure. Much to his delight, she’d seen fit to let him inside her after the oral worship. He’d climaxed in less than a minute, but Bella hadn’t offered sex as a means for both of them to orgasm. She’d offered it as a means for Zack to have the most satisfying orgasm possible. It was a gift he deeply appreciated and he’d made that clear after he’d unloaded in the condom she put on his cock before they fucked.</p><p>After a long day at work and a long evening of pleasure – starting with Luke and ending with Zack – Bella had jumped in the shower, leaving Zack to head to the kitchen for a glass of water before he retreated back to the bedroom for a well-earned night of rest.</p><p>Zack perked up when he heard footsteps coming down the hallway and he smiled as Camilla entered the kitchen in a pair of pink satin shorts and a rather skimpy camisole.</p><p>“Good evening, Zachary,” she said with a smile on her face.</p><p>“Hey, Camilla,” he replied. “Can I get you anything to drink?”</p><p>“A glass of water would be lovely,” Camilla said as she pulled out a chair and sat. “It sounded like you and Bella had fun tonight.”</p><p>Zack grabbed a glass from the cabinet and filled it with cold, filtered water from the fridge as he smiled at Camilla. “We certainly did.”</p><p>“Sit and share the details,” Camilla said.</p><p>Zack handed her the glass and pulled out a chair to sit with his future mother in law. “Well, I met Bella downtown so we could go to dinner after work. We were talking about our relationship and Luke and that sort of stuff on the way there and somehow we arrived at a place of arousal. There was something kissing, some teasing, some dirty talk. Bella decided she was going to fuck Luke before our dinner so she went to the bar and sent me to the restaurant to get seated at our table.”</p><p>“My daughter certainly isn’t shy about pursuing her pleasure, is she Zachary?” Camilla interjected.</p><p>“She certainly isn’t,” he replied. “Her hair was a little messy and her dress a little rumpled when she arrived at the restaurant, though I’m pretty sure that was on purpose. We’ve gotten to a point where Bella knows and accepts that I’m turned on by the fact that she’s having sex with Luke and I think she wanted to show it off.”</p><p>Camilla chuckled and sipped her water.</p><p>“Anyway, after we ordered Bella told me to meet her in the bathroom and then got up and headed that way. I joined her a minute later and she dragged me into the bathroom, pushed me to my knees, and had me go down on her. She filled my head with dirty talk about sex with Luke and I was honestly hard as a rock. It felt so good, Camilla,” he said.</p><p>“That’s because you’re a natural born cuckold, Zachary,” she replied. “I’ve helped you realize that, of course, but it was in you all along. You’re the sort of man that can’t help but get aroused as he tastes his girlfriend’s pussy after another man has been inside her. You’re a rare breed, which is a wonderful thing for my daughter, for she’s going to be very happy being married to a cuckold.”</p><p>“I feel so grateful, Camilla,” Zack said as he got caught up in feelings of warmth for his future mother in law. “I feel like you’ve ensured that Bella and I are going to be happy together, that she’s actually going to be willing to marry me, and I can’t tell you how much that means to me.”</p><p>Camilla reached out and ran her fingers over Zack’s arm as she said, “I did it for my daughter, Zachary. I know her better than she knows herself in some ways, and I knew she’d end up divorcing you if you weren’t willing – eager, even – to be her cuckold. Did you make her cum with your tongue?”</p><p>“Not in the restaurant, no,” Zack answered. “It was just a little teasing. Bella went down on me for a little bit and then we returned to the table and had our meal. She played footsie with my cock when she could do it without anyone seeing and by the time we were finished I was desperate for relief.”</p><p>“Did you get any?” Camilla asked.</p><p>“Bella kept teasing me on the drive home,” he said. “She took out my cock and stroked me while I drove. She told me about how Luke fucked her. She told me how good he felt inside her. She stroked slow enough that I didn’t cum, but it felt so good.”</p><p>Camilla lifted her foot and placed it between Zack’s legs. Her toes worked their way towards his cock and he felt a small rush of panic.</p><p>“Camilla, I don’t know if we should do that while Bella’s home,” Zack said. “I don’t know what she would think.”</p><p>“No, you don’t,” Camilla answered. “And I think we both know you’re not really in charge here, don’t we, Zachary?”</p><p>Her toes found his cock and Zack gripped the edge of the table as he felt a surprising renewal of his lust.</p><p>“I heard my daughter moaning quite a bit after you got home, Zachary,” Camilla said. “Did you make her feel good?”</p><p>“She let me go down on her,” Zack replied as his cock came to life. “She let me strip her naked and then she got in bed, spread her legs, and invited me between them. She told me all about the sex with Luke, about how they fucked on his desk and then she bent over it and let him take her from behind. She told me about how she pulled out a chair and sat on him and rode him while they kissed and he played with her breasts.”</p><p>“Did you masturbate while she told you about fucking her ex-boyfriend?” Camilla asked.</p><p>“I did,” Zack answered. “But I wasn’t allowed to cum.”</p><p>Camilla smiled. “No, of course not.”</p><p>Zack moaned as Camilla’s toes brought his cock to a full erection. “Eventually Bella came on my tongue. Only then did she invite me inside her. It was incredible, Camilla.”</p><p>“You came very quickly, didn’t you Zachary?” she asked.</p><p>He nodded.</p><p>“That’s okay,” she said. “It’s good, even. A cuckold is rarely capable of satisfying his wife when they have sex, so it’s better that he cum as quickly as possible. That way she can enjoy the fact that you find such pleasure in her pussy without having to endure a seemingly endless fucking that will bring her little to no satisfaction.”</p><p>“She did seem happy afterwards,” Zack replied.</p><p>“Of course she was happy,” Camilla said. “My daughter loves you, Zachary. She loves you dearly. She wants to marry you. I’m certain of it. She probably would have married you without your willingness to be cuckolded. She would have divorced you or started cheating on your soon after, but now none of that is necessary. As long as you continue to evolve into the perfect cuckold, Bella will be as happy as a woman can be when you’re married.”</p><p>Zack had thoroughly enjoyed his evening and there was no question in his mind he’d enjoyed it more than he would have if he’d fucked Bella in the restaurant bathroom and that had been the end of it. Instead, she fucked Luke, spent a few hours teasing Zack, and then welcomed him into her pussy after she’d claimed her second orgasm of the night. It seemed that everyone had gotten the best version of what they wanted.</p><p>“You should encourage Bella to let Luke cum inside her,” Camilla instructed.</p><p>“What?” Zack asked.</p><p>“She wants it, Zachary,” Camilla said. “Every woman wants the man she’s having sex with to cum inside her. It’s far more satisfying that way. You should encourage her to go on birth control so she can start letting Luke cum inside her. It will deepen her satisfaction. His too. Plus, you need to get used to the sight of another man’s cum leaking out of Bella’s pussy. It will help you get to a place where you’re eager to clean her pussy after she’s been with someone else.”</p><p>Camilla had mentioned that before and Zack still couldn’t wrap his head around the idea. It seemed so wrong, so disgusting. He just couldn’t imagine doing it.</p><p>“I know it’s scary, Zachary,” Camilla said. “But it’s part of being a good cuckold. There’s no better way to show Bella that you both know your place and embrace your place. When you crawl between her legs and lick her lover’s cum out of her, Bella will know that you’re a cuckold through and through. She’ll know she doesn’t have to worry about you, that she’s free to enjoy other men as she sees fit. Plus, it will help keep your ego in check.”</p><p>“It just seems so…gross, so humiliating,” Zack replied.</p><p>“It is,” Camilla said. “Very few things are more humiliating than licking another man’s cum from your wife or girlfriend’s pussy. That’s the point, though. A cuckold must be humiliated to keep his ego in check. Otherwise he’ll inevitably argue with his reality. You don’t have to do it anytime soon, Zachary. You just have to convince Bella to let Luke cum inside her. The clean up can come much later. Will you do that for me, Zachary? Will you show that you’re a suitable husband for my daughter and convince her to invite Luke to finish inside her?”</p><p>Zack nodded. He’d long since learned that resisting Camilla was pointless.</p><p>“Good,” she said before pulling her toes from between his legs. “Alex was supposed to come over tonight but he got called away on a work emergency, so I’d like you to make me cum before Bella finishes showering. Can you do that for me?”</p><p>“Yes,” Zack said.</p><p>Camilla pulled off her satin shorts and revealed her pussy. “Get on your knees, Zachary. Eat my pussy like a good boy. Make me cum.”</p><p>Zack slid off the chair and fell to his knees. The whole thing felt insanely dangerous, but he did as Camilla desired. He ate her pussy with every bit of skill he had. He made her cum fairly quickly, thanked Camilla for her continued help, and made it back to the bedroom before Bella was finished with her shower.</p>
