This prompt is still open. This is for 18 erotic roleplay.

I woke up with a groan. "What the-" The bed was rocking and my heart was beating rapidly within my chest. Adrenaline quickly brought me to my senses, and the pale moonlight on my wife's naked body told me everything I needed to know. "Katie?"

I barely got her name out when I moaned. My cock was buried inside her hot, wet pussy. I felt like I was about to cum, so God only knew how much she had edged me before mounting me and waking me up.

Katie whimpered, "Yes, baby... Give me that big dick..." Her inner muscles tightened around me, squeezing my cock and urging me to cum inside her. She heard me and turned her attention back to me now that she knew I was awake. She let out a primal sound of pleasure and said, "I was nursing the babies, and when I came back... I had to have you. You were already hard for me."

I must have slept through the midnight feeding. At mention of it, my eyes dropped to Katie's big tits. She had been busty before the pregnancies, but she had grown twice as big from them. Even now pearly, white drops flowed down her tits. None of our babies would ever go hungry, she made more than enough, even enough to share with me. She knew the power her feminine curves had on me.

"Baby, I'm going to cum," I said in a hurried warning. Katie just moaned and bounced faster on my dick. I felt panic and pleasure rise within me at equal pace. Katie had promised that we would be careful, that we wouldn't get pregnant again so soon after the last time. Not like the second time, or the last time. A strangled groan and grunt emerged from my throat as my heavy balls pulled up and thick, potent cum rushed out of my body and blasted into my beloved wife.

As soon as she felt my seed splash inside her she came, and pushed me as deep as she could inside. She wanted to be sure her womb was soaking in baby batter. For the next several moments we were consumed with our combined pleasure and the natural drive to breed, despite my logical objections.

Katie collapsed onto my chest, her pussy milking me for every drop and her warm skin pressed to mine. After a few minutes, she nuzzled me, kissing my chest, and dismounted, pulling the silk night robe around her body and laying back in her spot. She laid on her back, hips cocked just so to help fulfill her mission. "I needed that," she said in a dreamy voice. "The waiting during the recovery time is torture."

I sighed. I wanted to say a million things, but I bit my tongue. I snuggled her from the side, "I love you." My big body encompassed her and she cooed.

A couple of weeks later Katie shared with me that she thought she was pregnant again with a big grin on her face, though she apologized since I told her we should wait a bit.

I had a feeling that this was no accident.

Katie and I got pregnant, we think, on the first night of our honeymoon. She had her IUD removed and we agreed condoms would ruin the fun of our first time together as a married couple. We got plenty of teasing when our families and friends found out and did the math.

My wife decided that she wanted to document our pregnancy and share it online. She had a lot of friends and family who lived far away, so posting about it helped her feel connected. I was happy to support her in this. The project progressed really nicely and more importantly the pregnancy was textbook perfect.

I had to admit that I loved the changes to her body. Her beautiful baby bump, her glow, her lustrous hair, her growing breasts, and her powerful sex drive all had me quite pleased about this happy accident.

Our baby was happy and healthy, and we were using condoms again until she was ready for more serious birth control. During a particularly passionate money just a couple of months after she gave birth, the condom broke. Katie bit her lip when she saw the shredded latex and the copious seed inside her. "I'm sure it'll be fine."

It wasn't fine - it was twins.

Katie was happy though. Her followers on YouTube/Instagram were overjoyed at her little surprise and it brought in more people. Now she makes enough money off her mommy/pregnancy content of it that she doesn't have to work at all.

And that has been the story since. Pregnancy has turned my pretty, perky fiancé into a fertility goddess. And I can't say it falls just on her either. It seems if she even gives me half a chance my boys will knock up whatever eggs her body offers up. The longest she has gone without getting pregnant since we started was five months.

And there's no signs of it stopping yet...

Hello! Thanks for reading my prompt. The basic idea I had here was a young couple that cannot resist or stop themselves from breeding over and over again, especially as the wife/girlfriend seems particularly unable to resist the urge.

I partially got this idea from a conversation with a friend about social media influencers who seem to embrace this kink in a seemingly wholesome manner. A lot of them are conservative Christian people who take on the mission to be 'fruitful and multiply.' I want the wife to be drawn to be kept barefoot and pregnant, that it feels so good to be pregnant she chases it and makes her stud husband breed her again and again.

I do love big sizes and endowments, growth, large pregnancies, idealized pregnancies (limited suffering or difficulties for the mother), and lots of milk. If this interests you as a concept feel free to check out my DPP Profile for kinks and limits and send me a message with your ideas for the RP. I prefer to write on Reddit and I like long-term projects.

I hope to hear from you!
