You hear footsteps from upstairs

You hear someone walking around upstairs, trying to be quiet. You make your way up the stairs quickly, thundering up to see a door swing shut. You slam open the door, and see the naked bottom half of a woman sticking out of a small opening in the wall. She seems to be attempting to wriggle her way through the opening, moving her legs quickly.

You dash over and grab her by the thighs, wasting no time and spreading her legs. You insert a finger into her and you her a soft moan from the next room over. She is moderately wet, but getting wetter as you firmly grip her legs and slowly rub against the inner walls of her pussy.

Once she seems sufficiently wet to take your member, you grab her other thigh and fully spread her legs. You then slam your cock into her pussy, and a moan so loud, surprised and horny emanates from the next room over that you can practically see the lewd expression on her face. Grinning to yourself, you start thrusting into her pussy. You start slow, drawing your cock all the way out and slamming back in at a pace that allows you to enjoy her pussy in its entirety as it flexes on your cock. With every thrust, you get a satisfied breath or moan from the other room.

As you pick up the pace, you slam against her ass again and again. The slow buildup of the beginning has gotten you both to the edge, and you know it. So you enjoy these last few minutes. You ravage her pussy, slamming in and out over and over until you hear the screaming moans of ecstasy and her pussy clenches down on your cock, milking you for as much as she can get out of you. Her legs go limp at the end, pumped full of cum and hanging half out of another room. You slap her on the ass and go look somewhere else.
