Collaborative sex stories let us write the plot together

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

Mark has set up a mat on the floor where he directs Rachel to lie. There are three cameras pointed down at her. One on her face, one full body shot, and one directed at her pussy. He then directs her to lift up her hips and point them skyward. She is so weak from the day’s fucking that two guys have to help her by holding her legs on either side.

Mark opens a small box from which he pulls out what looks like a diaphragm. It is shaped just like any other diaphragm, but has a smooth metal disc on top of the dome that extends down into the cavity of the diaphragm about an inch. Mark turns it over and over, showing it in high detail and explains how it works. “This device has a metal insertion tube that flares out at the tip and is connected to the top of the diaphragm dome. The flared end is wide open, but the dome end has multiple layers of medical grade rubber that overlap and form a seal. It will allow an object such as this metal tipped inserter on the end of this plastic tube to be pushed into it like so. In this next scene we will be inserting this diaphragm into Bianca’s cervix then we will pump as much of the collected cum in that gallon jar and any more cum you men can produce directly into her uterus. The audience will get to watch as the cum is pumped into her uterus and her flat belly starts to distend. When all of the cum is pumped into her, the insertion tube is removed and all of that precious sperm-filled cum will remain inside Bianca. She will carry it around inside her until we are ready to let it out. To ensure it stays there I have this!”

He pulls out a vinyl bikini with buckles on either side and a zipper down the front. He shows us that there are two twelve inch dildos with the one in front that looks like it has a cup at the tip, both attach securely to the bikini bottom. “The promise we will make to the audience will be that if they pay a special fee, they can come back during a special midnight showing Monday to Thursday or a mid-morning showing on Fridays to Sundays to see the releasing of the cum.”

Rachel looks on in amazed anxiousness but doesn’t raise any objections.

Mark proceeds to insert the cervical plug. He doesn’t use a speculum or anything else to open up her pussy. He just shoves his whole hand inside her. Rachel makes a grunting noise and bites her lip as Mark’s hand reaches her cervix. Her eyes shut tight and her hands reach out to the edges of the mat, grasping so tightly her knuckles turn white.

“Got it!” announces Mark, and Rachel seems to relax. “How does that feel?” Mark asks her.

“Actually, not too bad. The longer it’s in there, the less uncomfortable I feel. I think it’ll be okay.”

“Good. Now let’s get ready to pump some cum into your uterus!” says Mark. He positions her on her back as before, with her hips points skyward. Mark pulls out a horse speculum which he inserts almost all the way and dilates her pussy open nearly three inches. Her cervical plug is clearly visible. The camera man adjusts the angle of the camera and shines a light into her body. Nothing will be missed. The metal inserter is pushed into the cervical plug and locked into place. The other end of the tube is connected to a small but powerful pump that is attached to a glass basin with an opening at the bottom that will allow liquid to drain out. This gallon jug is then pours into the glass basin which is filled nearly two thirds of the way. Mark turns on the pump and you see the collected cum being pumped through the clear plastic tube and finally into Rachel’s waiting womb.

“Aaahhhhhhhh” Rachel cries out for nearly ten seconds. The pump is slower than you thought it would be, but all of the men are continuously jerking and adding to the basin, eventually adding another half gallon of cum into the basin. It takes the pump nearly ten minutes to get all that cum inside your Rachel’s womb. Mark is very good at shutting off the pump so no unnecessary air is pumped into her. He pulls out the tube and pulls out another gallon jug. “This is what we collected from a hundred random black men in ten different neighborhoods this morning.”

He pulls out a gigantic syringe, sucks all of the cum from the gallon jug into it, then pushes about ten inches of it inside your girlfriend’s asshole. She screams, “Aaaaiiiiiiiiii!!!!!” He then pushes down hard on the syringe and Rachel stops screaming and can do nothing but grit her teeth and try to breathe. When the syringe is empty, Mark quickly removes the horse speculum from her pussy and puts her in the vinyl bikini with the two dildos attached. He expertly inserts the two dildos, pushing them in about eight inches each. Then he grabs the sides of the bikini and pulls hard, making them go into Rachel the rest of the way, but hard and fast. “Oh my god, oh my god, oh my god…” is all that comes out of her mouth.

Mark zips her up and tightens the straps. He then takes out three small locks and secures the zippers and buckles. “So you don’t try to take them out tonight.” He stands her up and she can barely stand up straight. Her once-flat belly is distended so much from the gallon and half of cum in her uterus and the gallon of cum in her intestines that she looks like she is eight months pregnant. Mark rubs her belly and gives her a long, spit-swapping kiss. He puts his arm around her waist and calls the day.

All the actors clap and cheer, then get dressed and leave the theater. Rachel starts to get dressed as well, but Mark suddenly turns to her and says, “You know, I think I’m going to keep an eye on you tonight, and maybe for the remainder of the play.”

He turns to you and says, “I’m taking her home with me until the play is over. You can call her and talk to her if she wants. You know my number. You are also free to come to any of the rehearsals, but you’ll have to pay to get into the shows. You might want to be here at midnight so you can see me draining the cum from her body.”

And with that he walks out of the play house with your girlfriend, not bothering to get her dress. She is completely naked except for the contraption that is keeping all that cum inside her. You watch from a window as they walk across the parking lot, cars driving by on the street. He is lazily playing with one of her breasts as they walk.
