Collaborative sex stories let us write the plot together

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

“Hey Rachel, let's turn over so I can be on top. I want to fuck another load of cum into your fertile pussy before we go to sleep…” John instructs your sexbot girlfriend.

“Yes John… please be on top of me, pounding your huge cock balls deep into this tight little cunt full of your sperm! I want nothing more to be completely saturated with your sperm inside…” Rachel says and rolls over with John.

“Oh yeah John… I love that dick inside my cult so much! Fuck me! Pound my pussy until it's raw!” Rachel begs her Asian boss.

This was definitely not in John's instructions, but Rachel seems to be just ad-hocing it and adding whatever comment she thinks John might want to hear in the skit. It's turning you on something fierce, but you have been so hard for so long, you just can't seem to cum. You keep stroking anyway… maybe they will do something really racy to get your balls to explode.

John takes his time this last time around and slowly fucks Rachel. His long, thick cock looks so damned big pushing into Rachel's little pussy. You can see her lips stretched so tightly around his shaft, getting pulled out nearly an inch every time John pulls his cock out of her body.

You look at your clock and John has been slow fucking Rachel for almost an hour. Her skin is sweating bullets and bright pink everywhere. John is dripping his sweat all over her body, especially her face. Their tongues are dancing in and out of each other's mouths.

You watch and begin to wonder why your sex with Rachel is not like this… why Rachel never sweats or begs you to make her pregnant… and then you look down and see how your four inch and very thin cock might not inspire her very much…

John announces he's gonna cum deep inside your girlfriend again, “Oh fuck Rachel… I'm gonna cum so hard inside your fertile pussy. I'm gonna deposit my sperm in your uterus… I'm gonna make you pregnant!” And he spasms as he pushes his cock balls deep into your girlfriend.

Rachel begins to spasm as well, “Oh Gawd John… yes! I feel your cum shooting into me! It's so hot! So wet! I love your hot cum deep inside me… I want you to make me pregnant! Please put your baby inside me!”

The two love birds shake and twitch and orgasm together until they calm down a few minutes later. Then John looks into your girlfriend's sweat dripping face and gives her a very tender kiss, “Hey Rachel, don't squeeze your pussy muscles. In fact, relax them and keep them as relaxed as possible. I want to see my cum pooled inside your gaped pussy…”

“Oh Course John… anything you want…” Rachel responds, looking very intently at her boss.

John slowly pulls out of her. As the tip of his cock clears her pussy lips, he uses his fingers to pulls her tiny pink and puffy slit open. For a slit second there's a gaping hole, then like a volcanic eruption, a thick white column of John's sperm-filled cum rises up from deep inside Rachel's pussy and threatens to bubble over… but not quite… then Rachel seems to breathe out slowly and the cum column inside her drops half an inch before rising again.

This triggers the most massive orgasm of your life. There was a thick column of another man's sperm filling your girlfriend's thighs pussy from the entrance to her uterus! It must have been a half inch thick! You cum in a fountain of sterile seminal fluid that sails over Rachel's work computer and hits the window behind it… the next three spurts land all over her monitor and keyboard, the next three hitting your face, then the rest landing all over your lap and belly.

You almost pass out, and your cock feel so painfully good, but John begins to speak, drawing your attention to the screen. “Wow Rachel… that's amazing. I can't believe how tight your pussy is, and how my cum can just sit inside you like that. Do you think us pretending to make you pregnant with my child helped Ross to get off and relieve his blue balls?”

“I'm sure Ross got off John… and I hadn't expected you to make me rub your sperm inside my pussy or cum inside me… I'm not on any birth control and I ovulated this morning…” Rachel responds sounding unusually calm.

“What? Why would you let me do this to you if you could become pregnant for real?” John questions Rachel, sounding pretty upset.

“You asked anything… and I told you anything… so nothing was off limits… if I get pregnant from this, I'm not gonna make trouble for you John… Ross and I will just keep it and raise it as our own… don't worry. I asked you for this,” Rachel says.

“I… I don't know what to say…” John sputters in disbelief.

“How about… you're welcome Rachel for making sexting with your boyfriend possible… and… I'd love to do more skits with you while we are here at the conference…” Rachel suggests… then she squeezes her pussy and all of John's thick, white cum oozes out of her and onto her belly.
