Collaborative sex stories let us write the plot together

(Her Secret Fantasy, continued by 7...)

“Yes,” you reply.

Rachel texts back a ton of love and heart emojis, telling you that you’re the best boyfriend in the world for letting her fuck a stranger, letting him impregnate her, fulfilling her fanstasy.

You get the rest of the bottle from the bartender, then go to the front desk and ask for a second room adjoining the first one. You know you’ll want your privacy for what comes next.

Your phone rings about ten minutes later, and your girlfriend tells you on video call, with Brian behind her, that the act is up and Brian knows what’s going on. The fake innocence, that Rachel is really fertile, and you’re going to watch him continue to fuck her and fill her with his cum. Brian, seemingly politely, points out that he tends to cum more the second time around. While you find that hard to believe, you just nod for now.

Over the next thirty hours you watch your girlfriend fucked relentlessly, taking massive load after load, and captured in HD on Brian’s professional grade camera, only breaking for an hour or two to eat room service in between sessions.

You lose count of the number of times Rachel squirts, instead keeping track of the number of times she goes temporarily blind from low blood flow to the optic nerves due to the constant orgasms.

After checking out of the hotel two days after you arrived, Brian catches you on your way out. “Hey, Ross,so there’s really no hard feelings about all this? I find it hard to believe.”

You smile thinly, then tell him, “It’s about her pleasure, her happiness. I love her no matter what.”

About sex weeks go by without incident, when your girlfriend suddenly comes down with a stomach virus. After seeing the doctor, she comes home to tell you what you already suspected — she isn’t sick. She’s pregnant.

You both decide to raise the child together as your own, although sex between you isn’t as intense as it used to be and Rachel starts seeming a little depressed. So around eight months into the pregnancy you surprise her with a visit from Brian while the kids are away at summer camp. While he obviously has to be gentle compared to the last time, when he leaves a week later your girlfriend is much happier, and more enthusiastic in bed with you.

About two months after the baby is born you both decide that maybe you want to try for a fourth kid, and promptly begin trying to knock her up. After two months of negative results though, Rachel approaches you with a crazy plan.

It would be a “couples” vacation, so your mom would watch the kids again while you and Rachel take a trip to the Bahamas. In reality she tells you that many men find their sperm perform better when faced with competition. You finally realize what she means — a baby roulette with a bunch of black locals’ sperm competing with your sperm. She also tells you that she found out Brian has a cousin that is similarly endowed, and that that could be an option as well. You consider this for a couple of days, with your girlfriend giving you time to decide without pressure.

Finally you sit down with Rachel and tell her what you decided.
