Collaborative sex stories let us write the plot together

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

Mary contorts her face in a painful squeal and practically falls off the desk, barely catching herself as Rachel roughly tugs her by the arms. Then your girlfriend presses the young woman forward against the desk and slaps her bluntly on the butt. “Mary today I promise you some real sweaty overtime where you get your money’s worth!”

Then she releases the handcuffs from one hand and pulls Mary’s arm across the desk to latch it to the table leg. Your workmate squirms a bit, but more for show, as it seems to you, because the following blow on her plump ass elicits a much more comfortable sigh than expected. Quickly, Rachel retrieves another handcuff from her pants pocket and ties Mary’s second arm to the other table leg.

She is now all tied up and bent over her own desk and at your mercy for good. Gosh! Your dick itches at the thought to plunge it into your coworker and inseminate her womb. You have to admit that you sometimes thought about exactly that when you both sat together at work.

But before you can think that out completely Rachel catches your attention. She spanks Mary once more but then moves around the table to stand in front of your tied workmate. Stroking Mary’s chin, she lifts her as high as she can with her body tied to the table and pushes her tongue into her mouth.

This displays the luscious ass of your beloved excitingly well and you envy Mary for a moment that she is guaranteed to enjoy it in front of you. Rachel has a few more well-distributed pounds than your young colleague and her waist is not so slim, but nice and grippy and her ass is just as soft and lush.

Now your girlfriend opens her pants without letting go of the kiss and peels out of the tight jeans. Then standing up after all, she turns around in front of Mary and bends down provocatively to take off her shoes and the pants right along with them.

This leaves her ass full and round in the rather large panties posing directly in front of Mary. Just like you, she stares enthralled at the covered mound of supple flesh. Oh Rachel is such a fucking bitch! you think and grin, while stroking the big bulge in your pants.

You watch as your girlfriend shifts her butt to the desk and half turns to reach for Mary to rub her face into her full backside. Mary makes a muffled moan, trying to breathe through the panty and Rachel giggles in pleasure. Then she takes off her shirt and bra and teasingly lets you ogle her gorgeous bosom, which she bobs around with both hands.

When she turns around again, Mary is staring at those big sagging breasts just as much as you were before. Rachel again pulls her up from the table by the chin and gives her the breasts.

Mary hesitates briefly, perhaps a little second thoughts about pleasuring a woman? But actually it is too late and no one gives her a choice. Without mercy your girlfriend rubs her breast against Mary’s lips and finally she complies and begins to kiss and suck her, so that your sweetheart grunts with pleasure.

Your boner gets painfully hard from the show but still you hold back, knowing that you might have a really amazing reward later. Or do you try to get some of it now?
