It took five weeks for Karen to get pregnant. We fucked at least once a day – and sometimes multiple times a day – during that span, and not in that mechanical way that couples sometimes do when they're desperate to conceive. It was wild, passionate, astoundingly pleasurable sex driven by our love for each other and our mutual lust for my seed to take hold inside her.
Jay was involved every step of the way. He watched almost every time we fucked and he frequently participated by preparing us both with his mouth. Occasionally I'd have him worship Karen's ass while she rode me and there were times when I'd have him eating my ass while I was inside her in missionary. I can't say for sure, but I'm fairly certain that Jay experienced the best orgasms of his life during that time, as each was infused by the idea that his wife was desperate for another man to get her pregnant. It's the ultimate form of cuckolding, after all - Karen literally chose not to let her husband pass on his DNA - and Jay couldn't help but get off on that humiliation.
I basically stayed with them for the entirety of those five weeks - I think Karen and I spent a few nights at my place, but otherwise I'd all but moved in. Jay was in the guest room, I was in the primary bedroom with Karen, and we were living like a couple with a cuckold servant there to tend to our needs and to indulge in his lust for humiliation as he did as we desired.
The day she got the positive pregnancy test was among the most joyful of my life. It wasn't until the moment that she came running out of the bathroom with the test in her hand that I realized just how badly I wanted to start a family with her. It was even more than that, though. It was that I wanted Karen in every way. I wanted her to be mine. Luckily, that wasn't something I had to convince her of. She was already prepared - eager, even - to be mine, as she'd expressed when we were on vacation.
We decided to delay any big decisions until after the first trimester, which is when most of the significant risk has passed. Then, right as Karen began to show, we decided it was time to make some genuine, permanent changes. We shared the first of those decisions one night shortly after the first trimester had officially passed.
"She looks beautiful, doesn't she?" I asked Jay as Karen stepped into the living room in a pair of boyshort panties and a camisole that stretched out over her newly-showing stomach. Her breasts had swollen a little, too, and her nipples were rock hard and poking through the soft fabric of her top.
I was sitting on the couch and Jay was on his knees in the middle of the living room, which was exactly where he belonged. He turned to look at his wife and his eyes lit up as he stared at her belly. "She does," he answered. "She looks perfect."
Karen stopped in front of her cuckold - who craned his neck to look up at her - and gently ran her hand over her slightly protruding pregnant belly. "I feel beautiful," she said. "Having his baby growing inside me has made me feel more beautiful than I ever have, Jay. It's made me happier than I've ever been, too."
Jay reached up and Karen smiled and took his hand. She placed it against her pregnant belly and he rubbed it slowly with a smile on his face.
"Does it turn you on, Jay?" Karen asked. "To rub my pregnant belly? To see my swollen breasts? To know that another man's baby is growing inside me? To know that I've chosen to start a family with another man instead of you?"
"Yes," Jay admitted.
I saw a hint of disgust on Karen's face, like she was embarrassed that her husband couldn't help but find it arousing that she thought so little of him that she'd chosen to have me get her pregnant. The look only remained for a few moments before swiftly washing away as Karen smiled at her cuckold husband and then joined me on the couch.
I put my arm around her, pulled her close, and we shared a deep kiss. She cuddled a little closer and her hand rested on my thigh. Her lips parted and she practically sucked my tongue into her mouth while moaning. I ran my fingers over her stomach and up to her breasts. I gently played with them in the exquisitely soft fabric of her camisole and Karen's moan deepened. Just like that, the intense, unyielding desire we'd felt for each other over the previous months was once again ignited. I absolutely would have enjoyed fucking her right then and there, but we had business to attend to, so the kiss ended and Karen remained cuddled up next to me as we both turned our attention to Jay.
"Jay, darling," Karen began, "we need to talk about the future."
"Okay," Jay replied with a wary look on his face.
"Things are going to change," Karen said. "Permanently."
Jay's nervousness seemed to deepen, and with good reason.
"I'm moving in," I added. "Permanently. I'll be selling my house - it's not really suitable for a family - and moving in with Karen so we can raise our family here. I'll use some of the money from the sale of my house to make improvements here - adding some extra square footage and an upgrade to the yard at the very least - and of course I'll be in the master bedroom with Karen."
"The guest bedroom will be converted to your room, Jay," Karen continued. "We can make any changes you want to make it exactly as you desire, but you need to accept that things will never go back to the way they were before I cuckolded you. What was once a thrilling sexual kink has become so much more for me. I'm in love with another man. His baby is growing inside me. For the past six months I've really been living with him, not you, and now we're going to make that arrangement permanent."
I couldn't quite read Jay's face, though I'm fairly certain that's because he was experiencing half a dozen emotions at the same time. I didn't really get a sense of surprise from him - he really shouldn't have been, given that I had been living with them for nearly six months by that point - but it looked like just about everything else a man could be feeling upon hearing that news was running through his body.
"So, what am I?" Jay asked after a long silence settled over the living room.
"What do you mean?" Karen replied.
"I mean, am I still your husband?" he asked. "Am I...I don't know, am I your roommate?"
Karen studied her husband for a few seconds and said, "Come closer, Jay."
Jay crawled towards us until he was on the floor in front of Karen. She spread her legs and beckoned him to come just a little bit closer. He did so and she reached out and caressed his face before gently guiding him to rest his head against the warm, soft flesh of her inner thigh.
"You're our cuckold, Jay," she said softly. "You're exactly what you've been since this journey began. This probably isn't how you envisioned this turning out, but now I know this is how it was always going to end. I was meant to be with a different kind of man. That's what makes me happiest. You were meant to be a cuckold, to serve me and the new man in our life. You were meant to submit to both of us, and that's what you're going to continue to do."
Jay turned his head and softly kissed Karen's thigh. He closed his eyes and his lips lingered against her soft skin as he purred.
"You don't have to be our cuckold, of course," Karen continued while reaching down to run her fingers through her husband's hair. "We'd both like you to remain with us and to serve as our cuckold, but you don't have to. You're free to leave if you desire."
There was real panic in his eyes when Jay looked up at Karen and me. "No, I don't want that," he said. "I want to stay. I want to serve. I do. I want to be your cuckold."
"You want to live a life of service?" Karen asked. "Because that's what you'll be tasked with, Jay. You'll serve us. You'll do everything you've been doing as our cuckold and a great deal more."
Jay nodded. "I want that. I do. I want to be a good cuckold for you. For both of you."
"Good," Karen replied softly. "That's good, Jay. That's what I want too." She leaned down like she was going to kiss him - her lips were inches from his - but instead Karen slipped two fingers into his mouth and pushed them all the way to the back of his throat. "You will serve us well, Jay," she said with a harsh edge to her voice. "You will know your place and inhabit it without question. You will not introduce any stress into our lives. You will be an obedient, submissive cuckold who understands his place. You will do everything in your power to make our lives better. Do you understand?"
Jay nodded as Karen gently fucked his mouth with her fingers. I was certain I saw a wild kind of desire in his eyes, as if Karen had tapped into a deep well of lust inside him and unleashed it with just a few well-chosen words.
"I'm horny," Karen said to her husband. "What should you do to help meet my needs in this situation?"
She pulled her fingers from his mouth and Jay looked at me and said, "I should fluff his cock for you."
Karen smiled. "Yes you should. Now do it, you fucking cocksucker."
Jay moved between my legs and got to work freeing my cock as I considered how significantly Karen's view of her husband had changed over the course of my time with him. There was a time when she felt genuine love and affection for her husband, but that had clearly faded as she'd witnessed him surrender over and over to his desires, many of which were built around his need to feel a deep sense of humiliation. Karen still felt some kind of affection for him - she wanted him to remain our cuckold - but she clearly didn't love him anymore, at least not in the same romantic way a woman tends to love her husband.
I couldn't really blame her. I suppose I'd ruined Jay for her. I'd humiliated him - for his pleasure, of course - and while he'd experienced the blissful highs of pleasure that cuckolding can provide, he'd also fallen low and lost his wife in the process.
"That's it, cocksucker," Karen said as she watched Jay take me in his mouth. "Suck on that big dick. Show us both that you know your place. Show us that you'll always know your place, that you understand that you're a fucking cuck and that's all you'll ever be."
Jay looked up at his wife - who'd cuddled tightly against my body and was busy kissing my neck as she watched her husband blow me - and moaned around my cock. He liked giving me head. He'd come around fully. He was every bit the cuckold I'd turned him into. He was everything Karen thought he was and I had every confidence he could remain a part of our lives and act as a good submissive cuckold that largely existed to make us happy.
Karen pulled her panties off, handed them to Jay - who'd gotten me hard - and said, "Put these on. Right now." Jay stood and stepped into her panties before dropping to his knees once more. Karen straddled me, looked over her shoulder, and said, "Put his cock inside me, cuckold."
Jay wrapped his fingers around the base of my shaft and guided me into her slick pussy. I felt her warmth and wetness envelop me as she said, "Now watch a real man satisfy me, cuckold."
Karen turned her attention to me and her face softened. The harshness she'd directed at her husband turned into a soft, loving look as she sank down onto my cock and kissed me. Our tongues mingled gently and I moved my hands to her ass and took a firm grip, helping her ride me at the speed I enjoyed.
"Does my pussy feel good?" she asked softly. "Am I making you feel good?"
Karen was submissive too. Just like Jay. She'd come to balance her dominant and submissive side as she'd taken greater pleasure in humiliating Jay, but at heart she was a sexual submissive and that side of her couldn't help but come out when we fucked. Of course, I liked that side of her, as I thoroughly enjoy being dominant in bed.
"You are," I replied with a smile. "You always make me feel good, Karen. From the first moment you gave me your pussy you've made me feel good. You've always been a good girl for me."
She moaned and rode me faster. "You've always given me everything I need, including the baby that's now growing inside me." Her pussy was soaked as she started riding me with wild abandon, like her body had demanded that she pursue her orgasm with as much vigor as she could manage and Karen just couldn't say no.
"Eat her ass, Jay," I instructed while spreading her cheeks.
I saw the look of joy on Karen's face when Jay's tongue found her asshole. She smiled at me, moaned, and then we kissed as she rode me faster. Her pussy felt utterly perfect and she seemed determined to give me a fantastically pleasurable orgasm while Jay rimmed her ass like a good cuck.
"Cum on my cock," I said as I got close to my climax. "Be a good girl and cum on my cock while your cuckold husband eats your ass."
It took just a few seconds for Karen to follow my order. She closed her eyes and let out a wild, loud scream of pleasure as I fucked my cock up into her pussy. A moment later I unleashed my seed inside her, claiming my climax while Karen's body trembled from the thrill of her orgasm.
"Lick up any cum that leaks out of her, cuckold," I instructed.
I felt Jay's tongue on my cock and balls. He was licking up my load like a good cuck. He was following orders without hesitation and he was doing so while wearing his wife's panties. He was exactly what we'd made him and it seemed like he was happy to be that way.

Selling my house and moving in with Karen and Jay was the most significant change we made in the first two trimesters of her pregnancy. It represented a full commitment to the idea of Karen and me starting a family together with Jay acting as our cuckold servant. There was one more change that Karen wanted to make, though, and one that caught me off guard.
She was a few weeks into her third trimester when she made her intentions clear. I'd long since moved in by that point and it felt very much like Karen and I were a happy couple with a roommate who also happened to be a sexually submissive cuckold that did everything in his power to improve our lives. In fact, Jay had embraced his role to such a significant degree that it really did feel like he was, without question, always meant to play the part of a cuckold.
I don't know if it was his embrace of that role that led Karen to her decision or if she'd always planned on it, but I arrived home from work on a Friday evening to find her at the kitchen table with a serious look on her face and a wealth of paperwork spread out in front of her.
"What's going on?" I asked.
Karen lifted herself from the chair - she was showing quite a bit at that point and she looked exquisite in a pair of leggings and a top that left most of her pregnant belly exposed - and stepped into a hug. She looked up at me, offered a soft and surprisingly romantic kiss, and said, "I've made a decision."
"What's the decision?" I asked.
"It's time for Jay and me to get divorced," she answered. "I'm not saying you and I need to get married, but it's time for my marriage to Jay to officially end."
"And those are the papers?" I asked as I gestured towards the table.
Karen looked up at me and nodded. I can't say I was surprised. Karen's decision was utterly unsurprising, in fact, and it was probably a long time coming. Still, it was a big deal and a fairly significant change, even if that change was on paper more than anything else.
"Does Jay know yet?" I said.
"No, not yet," she replied. "I was thinking we could tell him together, in fact. I assume you're okay with him staying in the home with us even after we're divorced?"
I nodded. "Absolutely. He's proven to be quite valuable, in fact. I never imagined taking cuckolding to this extreme, but I feel like Jay is really well-suited to it."
"He is, isn't he?" Karen replied. "Can we tell him tonight, then?"
"Of course," I said. I paused for a few moments before adding, "I do want to marry you, by the way. After the baby comes - and I want to do a proper proposal - but I do want to marry you."
Karen looked up at me with complete and utter joy on her face. I think she would have been okay with not getting married, but it was clearly something she wanted. I wanted it too - and we did end up getting married about six months after the baby arrived - but that's another story.
Karen kissed me with intense passion and then pushed me into one of the kitchen chairs. She straddled me - she was still capable of doing that despite her increasingly large belly - and ground her hips over my crotch until I had a throbbing erection. Not long after, I was inside her as she slowly moved back and forth over my crotch, milking me with her pussy as we kissed and slowly moved towards our mutually blissful climaxes.
I came inside her, she came on my cock, and then we took a shower together and cleaned up before Jay got home. We had him come to the living room and strip naked, which he did without question because he's a good cuckold. Karen then produced a pair of panties - she'd tucked them into a pocket - and had Jay change into them before falling to his knees.
"Are you enjoying your life as our cuckold?" Karen asked.
"Yes," Jay admitted with a vigorous nod. He looked a little nervous, though it struck me that his nerves came from a worry that Karen was about to tell him he was no longer welcome to be our cuckold. "I love it."
"And you believe you're well-suited to life as a cuckold?" she asked.
"Yes, yes, I do," Jay replied. "It's my place. I know most men wouldn't like it, but I do. I really do, Karen."
"Come closer," Karen said.
Jay crawled closer and when he reached her feet she leaned forward and ran her fingers through his hair. It looked a little like she was showing affection to a pet, which in some ways was exactly what she was doing.
"I think you're a wonderful cuckold, Jay," Karen said softly. "You've done everything we've asked of you. You've taken on a large role in maintaining the house and doing chores. You always offer sexual service when requested. You suck cock. You eat pussy. You clean us both after we've had sex. You find it endlessly pleasurable that another man's baby is growing inside me. You've surrendered most - if not all - of your masculinity to us."
While most men would have been horrified to hear how they'd been reduced to something far less than a man, Jay seemed thrilled by it, as if every single thing Karen mentioned turned him on. In that way, he was a cuckold to the core.
"However," Karen began, eliciting a panicked look on Jay's face, "you're not longer well-suited to being my husband." She let that revelation hang in the air as Jay looked up at her with worry in his eyes. "Which is why I'm going to divorce you."
I was honestly a little surprised that Jay didn't seem more panicked by the news, though perhaps I shouldn't have been. Looking back on it now, I understand that Jay wasn't panicked because Karen hadn't said a thing about refusing to let him remain our cuckold, which was, as it turns out, the only thing he really cared about.
"You will no longer be my husband because you're not worthy of being my husband," Karen continued. "You're a panty wearing, chastised, cocksucking, cum eating cuckold."
It was utterly unsurprising to see arousal on Jay's face as Karen offered up the kind of humiliation he'd come to crave.
"You're not really even a man, and I deserve to be married to a man," she said.
Jay looked at me and then back at Karen and asked, "Are you...are you marrying him?"
"Eventually," Karen answered. "He'll be my husband and the father of my baby. He'll be the head of our family. He'll be the man of the house. If you choose to remain with us, you'll be our subservient cuckold."
"I want to remain with you," Jay said immediately. "I want to be your cuckold."
"You'll sign the divorce papers?" she asked.
Jay nodded.
"That makes me very happy, Jay," Karen said as she stood up and slowly stripped as her soon-to-be ex-husband stared up at her with worshipful eyes. Once she was naked Karen ran her hands over her beautiful, pregnant belly and asked, "Would you like to kiss it, Jay? Would you like to kiss my belly?"
Jay nodded and Karen stepped closer. Jay leaned forward, closed his eyes, and pressed his lips against her wondrous pregnant belly. It had become something of a ritual between them, and each and every time it seemed to bring Jay a wealth of pleasure. He almost always moaned while kissing the ultimate symbol of his status as a cuckold and he almost always seemed to feel a rush of arousal between his legs, as evidenced by the look of mild pain while his cock tried in vain to get hard in its cage.
"Worship my pussy, cuckold," Karen instructed.
Jay kissed his way down her belly, sank a little lower, and put his tongue to work on her pussy.
"You will never fuck me again, Jay," Karen said. "If you stay with us, you will never fuck anyone again. You will forever be a pussy free cuckold. Your cock will spend most of its time locked in that cage, because that's where it belongs. You'll spend most of your time in a pair of panties, because a man like you doesn't deserve to wear men's underwear. You'll be permitted to worship my body and you'll do a great deal of cocksucking, of course, but you won't ever fuck anyone again, because you're not worthy of pussy."
Jay licked with great passion as Karen laid out what his future would look like. Her rules made perfect sense to me. I probably wouldn't have objected if she wanted to throw Jay a pity fuck from time to time, but I wasn't going to object if she decided that keeping him pussy free was the way to go. He was, after all, utterly incapable of satisfying her and there was nothing wrong with punishing him for that.
"We may find someone to fuck you," Karen said.
That elicited a panicked-sounding moan from Jay, though he didn't stop licking her pussy.
"We may find a man that's more than happy to bend you over and take your ass, Jay," she continued. "That will be the only kind of sex you're allowed, and in time you may come to enjoy getting fucked in the ass and taking a thick, creamy load in your hole like a good little bitch. You won't like it the first time - no man likes getting fucked the first time - but you might get used to it, you might come to crave it, we might even be able to offer it as a reward when you're a good cuckold."
I have to admit that I was somewhat astounded by Karen's transformation into a woman willing to take control of her cuckold. I felt proud, too, like I'd trained her well and she'd learned all the important lessons while playing the part of my sexual submissive.
"Are you leaking precum into your panties?" Karen asked.
"Yes," Jay admitted before immediately returning to licking her pussy.
"How pathetic," she said with a laugh. "I've just told you that every bit of your masculinity is going to be taken away and you're turned on. I guess this is exactly the kind of man you were meant to be, Jay."
Karen grabbed a handful of his hair and rubbed her wet pussy over his face for a few moments before stepping back and then turning and heading for the kitchen. She returned with the divorce papers and a pen and then set them on the coffee table and said, "Sign."
Jay grabbed the pen, turned, and signed the papers without hesitation. Just a few days later their divorce would be official. Jay would be nothing more than our cuckold.
"Now suck his cock," Karen instructed. "Get him hard. Then you can watch him make love to your pregnant wife."
Jay turned around, got between my legs, and freed my cock to take me in his mouth. He sucked like a man possessed and he did so for his wife's pleasure. He got me hard and I made love to Karen on the couch while Jay watched. He cleaned us up afterwards and then Karen instructed him to make dinner while we cuddled on the couch. Like a good cuckold, Jay did exactly as his wife desired.
And that's where my story ends. Years later, Jay remains with us. To the outside world we seem like a happy couple with a son (and a daughter on the way) and a helpful roommate that lives with us. Jay's submission is complete as he spends the entirety of his live in service to us, and by all accounts he's never been happier. The same goes for me and Karen, too. Things really are blissful and I can't imagine how they could get any better.
I couldn't have predicted how things would turn out, but I'm thrilled that I found Karen and Jay and that I was exactly what they needed in their lives, just like they were exactly what I needed.
The End.
