A man's hand

You can tell by the shape and weight of it against your cheek that it belongs to a man. His hand gropes and squeezes at your cheeks, slowly prizing them apart and exposing more of you to the cool air. Then you hear the sound of trousers being undone, muffled through the wall.

Suddenly a hard cock flops down against your wet pussy. It grinds slowly over your lips, before the tip presses against your entrance and thrusts inside you. It only takes him one motion, and he starts to fuck you quick and hard. His hands grab that of your thighs which sticks through the wall, using it to pull himself closer and harder against you as he continues to pound you relentlessly. You can hear him starting to groan, lost in the pleasure of using your pussy. All you can do is lie there and take it, tied down to the bench beneath you.

Eventually you can feel him start to tire, and you know he must be close. His thrusts have slowed down, becoming more forceful instead, rocking you and making your tits bounce. He makes an especially large thrust, and you think he's about to cum inside you until he pulls out and you feel his hot cum splatter over your pussy and lower stomach.

He gives your ass a hard slap and you can feel an odd sensation, like someone's writing on your asscheek.

"Number One." You hear him mutter under his breath. "Good slut."

You can tell he's walking off, and you can also tell someone's already taken his place by your exposed rear end.
