Collaborative sex stories let us write the plot together

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

Rachel comes home the next day very late. It’s a good thing you put the boys to bed because she is looking like shit. Her hair is dishevelled, her facial makeup is all smeared and it looks like she has dried cum all over her face.

“How was your day?” you ask your exhausted looking girlfriend.

“Oh Ross… today was the most exciting and most humiliating day of my life!”

“What happened?” you ask, starting to develop a hard on.

“First of all, I had to get all my work done today before noon and the dildos in my ass and pussy were so uncomfortable,” Rachel starts. She begins to describe how as soon as she completed her work, John called her into his office and had her strip. Then he put a thick leather and metal collar on her neck and attached the loop to a leash. After walking her around on her hands and knees for a few minutes, John sat on his couch for a while petting her hair, her back, her tits, and her ass.

Then John walked her over to his desk, made her crawl under and point her ass at his chair. Slowly removing the two dildos, John inserted his giant cock directly into her asshole to replace the dildo. He kept his cock inside her as he returned to work.

Rachel went on to explain how John had two appointments, each a half hour long with his cock buried inside her asshole under his desk. After his second meeting Rachel describes how John shuddered and emptied his nuts deep inside her bowels.

Rachel says her body went into a near convulsive orgasm from the powerful jets of sperm shot into her asshole with John’s cock balls-deep inside her. Rachel said she could feel the hot jets of cum so deep inside her body it felt like he was filling up her stomach!

As the day went on, John slowly fucked her and filled her asshole with three more large loads of cum, each time cumming into her bowels, and keeping his mostly still-hard cock buried inside her. Rachel described how she could feel his cum overflowing out of her ass as he slowly fucked her and could feel the hot cum flowing over her spread pussy lips, and run down in gooey rivulets down her belly and inner thighs.

“It wasn’t until five minutes to five that John pulled his cock out of my asshole and replaced the two huge dildos in my ass and pussy, Ross. I think some of his cum might have gotten into my pussy when he jammed the large dildos back in me,” Rachel says looking anxious as hell.

“When do you ovulate?” you ask.

“In three days Ross,” Rachel responds.

“Shit! That’s cutting it close. You need to tell him to not get any of his sperm in your pussy, babe. You’re not on any birth control!” You say feeling some panic rising inside your throat as well.

“I’ll try Ross, but he doesn’t let me say anything when he has me in his office being his plaything,” Rachel says, closes her eyes, and covers them with her forearm as if to prevent herself from crying.

You scoot over and give her a big hug which she seems to appreciate. After a while she gets cleaned up, calls John and goes to poop.

“Good girl Rachel. Now this time, have your boyfriend Ross hold the camera and angle the lens so I can see you pushing the poop and all my cum out of your asshole, you slut!” you hear John say to your girlfriend.

“Ross? Can you help me please?” Rachel calls like a dutiful slave.

You do as she asks, and point the camera at the space between her legs. You are able to get the phone down between her legs and partially in the bowl so the angle catches the slowly spreading pucker as she pushes her shit out.

It’s a huge log and smells so bad it makes both you and Rachel gag when you smell it. You stare at the bowl and a gush of thick white cum flows out of her ass like diarrhoea. It’s a thick stream that splashes into the water. You can also tell there is a substantial amount of shiny cum stuck all inside her spread pussy lips.

“Good girl Rachel. Now have your boyfriend wipe your ass, then get those dildos back inside you, my little cock whore!” John says so commandingly you almost drop the phone in the shit-cum water in the bowl.

You wipe Rachel’s ass — something you never imagined ever having to do — then jam the dildos back inside her like you did last night, pushing them into her hard so she can get the buckles clasped.

John dismisses her and Rachel gets into bed next to you, completely exhausted.

“Thank you Ross. You’re the most supportive boyfriend ever!” Rachel says and falls asleep. She snores loudly, something else she has never done before in the time you have known her.

You are thinking how fucked up your lives have become in just three short days, and that’s what you fall asleep to.
