Collaborative sex stories let us write the plot together

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

As your best friend’s cock is buried deep inside your girlfriend she looks at you and says, “How could you do that to me, put his cum in me without my knowledge? Is this what you wanted? Me to be slut and fuck his huge cock? Well?”

“I was just having a bit of fun, I didn’t want you to fuck him.”

“Jamie, harder… I need to feel your massive cock, it’s much bigger than his. I want to feel full. Sorry, you were saying?” she says looking at you with a sly smile.

Jamie picks up the pace behind your girlfriend, slamming his rock-hard cock into her soaking wet pussy. “Wow, you are so wet Rachel, I can’t believe it!”

“What can I say? I’m a slut for my boyfriend, but at least I now know about it. You are a bastard though. What about your wife Emma?”

Jamie grins at Rachel. “Oh don’t worry, there’s plenty to go round, slut!”

As all this is going on you are sitting there quietly with the biggest hard-on of your life, watching your girlfriend get fucked and loving it. Suddenly Jamie picks up the pace and as Rachel starts to moan (something she’s never done with you) Jamie pushes deep inside her and you can tell he’s just erupted by the look and sounds of your girlfriend.

As he pulls out a torrent of cum flows from her cunt. Smiling, Jamie stands up. “Well I better get back to Emma, thanks for that. Anytime you want a fuck let me know.” He looks at you. ‘“Cheers mate, see you soon!” And with that he walks out of the room.

Your girlfriend looks at you. “It’s okay, you can get your cock out now. Jamie’s gone so you won’t have to compare the difference. Now get on your knees and suck my cunt. It’s your fault it’s this messy. Once it’s clean I might let you cum.”

Slowly you lower your head and gently begin to lick your girlfriend’s swollen pussy, which is covered in your mate’s cum. As you try to pull back, your girlfriend pushes your head deeper into her. “I’ve decided I like being a slut,” Rachel says, “but I’m not sure what I’m going to do about it. I know, tomorrow we’ll watch two more films at random and we re-enact one of them. You get to choose which one we do but you have to help me recruit the cast.”

She gushes onto your face in one huge orgasm. As she finishes, Rachel stands up and takes her knickers of the floor and wipes herself with them, trying to soak up the juices. “I’m going to have a shower, you take care of yourself. Here,” she says, throwing the wet knickers to you, “you can use these if you want to help you cum.”

She slams the bathroom door on her way out.
