Find another way to get off.

You both are sporting erections again by the time you are home. Neither of you put your cocks away. She follows you closely as you walk to your appartment building. Her cock bumps you with each step, leaving a dab of precum on your butt. Your fellow residents look on in shock and jealousy. The old people jealous they can't do young people and the gay guys next door jealous that this large cock is attatched to a female body, which turns them off and leaves you free to enjoy your kinky desires.

She has your butt coated with enough precum to lube her entire cock as she presses it to your butt. She bends you over and pushes her cock into your ass before you even finish climbing the stairs to your floor.

"You looked so hot climbing those stairs. I had to tap that ass now. Mmmmm...yea I'm just gonna cum now..."

She pulls out, and shoots onto your ass. There is more than the first time, and it is thicker and the ropes stay stuck to your ass which you stuck out farther to catch them. Some people look shocked...others, interested.

"If anyone else wants a piece of this cock, get in line. He gets as much as he wants, first." She giggles and has her cock in your ass again. She gives you a minute or so of fucking. The cum squishes all over her crotch and your ass. She then cums on your ass again. Since the cum was spread around, your ass is all shiny now.
