Four is better than one.

"Sounds good to me," you answer. Evan leads you and the girls down to the parking garage, and in less than half an hour, you're pulling up behind him at a nice apartment building. The four of you ride the elevator to the topmost floor, and the girls make no disguise about their groping of each other, Evan, and you. At one point, the girls are making out while rubbing both cocks through the respective owners' pants. You know you've fantasized about Nat more than once, and your current view down her blouse is nothing short of fantastic.

The elevator chimes and the doors open. Nat doesn't give up even when you and Sarah shift away. Evan smiles and explains, "Four apartments on this floor. Two are empty, and the third one is an old deaf guy. Nat and I had sex outside his door for two hours once and never had a complaint lodged."

Sarah giggles, but that might come as much from the hands under her shirt as it does from Evan's story. He leads you into their apartment, already stripping down. Even you have to admit, the guy is good-looking. Nat is busy taking off Sarah's clothes. You start to strip down as the door finally closes.

Sarah's top comes off first, revealing her firm breasts. Nat starts to suck on a nipple as she works at Sarah's skirt. The sheath of black fabric falls, revealing her full nakedness at last. Evan's cock leads him to the new girl, and his tongue starts to twirl with hers in the split second before their lips meet.

Dropping the last of your own clothes, you move to Nat and start by lifting up her dress. Bringing it up to her hips, you reveal a lacy black thong splitting her tight ass in half. You give it an appreciative spank and pull the panties down, letting them drop to her ankles as soon as you're able.

Nat pulls away from Sarah's tit for just a moment and looks over her shoulder at you. She smiles. "You want to fuck me? I want you to fuck me. Just don't jizz in my pussy." She slips two fingers into Sarah's hairless cunt while Evan fondles her tits. Nat winks at you. "You can cum in my ass if you want, though. There's lube in the drawer right there." She nods toward an end table within arm's reach. You slide a finger into Nat's pussy, wiggling it around inside and getting it soaked before sliding it into her tight, hot rosebud.

Evan takes Sarah's hand and puts it on his cock. She begins to stroke him, slowly at first, but picking up speed in time with Nat's movements. She breaks from her kiss to inhale sharply, releasing it as a lust-filled moan. Your cock is throbbing; you need release, and there are two holes in front of you that you'd only previously imagined.
