just out of sight (consensual rough stuff)

you stand yourself just behind the door with your jumpsuit unzipped to the crotch letting your breasts and cock hang ready for use. you hear a click and hydraulic door noise as a pale blonde woman in a lab-coat enters the room. you immediately come up behind her grabbing her up with your arms around her stomach grasping her neck letting your erect dick slide between her legs as she quickly dampens at the shock.

you: you opened your schedule just for me to ruin you today for a whole hour? you must want mommy to punish you today, such a disgusting girl making me do these things to you.

you tighten your grip around her neck just barely impeding her breathing as you slide your cock down her crotch and up her crack as she wimpers in your grasp looking up at you in vain with pleading puppy dog eyes.

you: you know what they say about "do unto others"? well i say a dirty girl wants a dirty punishment.

as you finish your sentence you push your cock against her panties forcing them an inch into her anus. your captive gives a pained yelp as you feel her twitching around the head. you give it another good thrust dropping her onto your crotch and you hear a snapping sound as her panties break from the stress you feel her shaking from the pleasure and see her cringing from the pain as you grind her ass in circular motions on your crotch.
