They do.

Sarah reaches down to your hand and taps you twice. The intent is clear, so you withdraw your hand and stop touching her. You believe she just didn’t want to get caught, though, and not that she has a problem with you touching her in general, so you slide your hand between your own legs. This gives you a fantastic angle to run your fingers all over Sarah’s ass from underneath.

Not only does she not make a move to stop you, she shoots you a quick smile letting you know she’s still into it. Happy everything is still good, you settle back and enjoy the rest of the movie, idly groping Sarah’s ass throughout.

Unfortunately, the movie doesn’t last forever and you’re eventually **** to go out and try out Grace’s new pool as promised. You have to spend three whole hours sharing the pool and hot tub with three beautiful women in their swimsuits which show off their fantastic bodies. All while indulging in Grace’s extensive **** selection.

Poor you.

Grace and Tori are wearing bikinis while Sarah opted for a one-piece. While it hides her midriff, it shows off about as much of her ass as the bikinis do, plus you can’t help but get aroused by the way it clings to her skin. Of course, you also can’t help but get aroused by just how much skin Sarah and Tori are showing either. Wins all around for you.

Eventually, the party has to wind down. Since all four of you have been drinking, Grace offers to let everyone stay over. She doesn’t have guest beds yet, but she has a couch and two air mattresses. You decide to be the gentleman and take the couch while the girls take the air mattresses in the guest bedroom.

Grace blows up the air mattresses while the two girls each start getting ready for bed in the two bathrooms. You wait your turn by sitting on the couch that’s going to be your bed tonight while remembering the feeling of Sarah’s ass. The way it felt to run your hands along it, squeeze it gently, and how it felt when she moved it around on your hard cock. Just the thought is getting you hard again.

“Am I interrupting?” A voice whispers.

You get startled back to reality to find Sarah – still in her one-piece - and having removed her swimsuit cover - standing over you with a smirk. You realize that you were rubbing your cock over your swim trunks without realizing it.

“Sarah, I…” You stammer, knowing that you got caught red (actually, almost white) handed and that there’s no good explanation for it.

"Was that...?" she says, trailing off. "Was that because of... I mean, you know."

"Because of earlier? Yeah. I really liked that. Your ass felt amazing."

She blushes slightly. "Well, it's a good thing I brought it with me," she says, twisting her hips to give you a profile view of her ass. The beautiful curve of it makes you subconsciously slide your hand back to your cock, rubbing it over your pants. She watches your hand, transfixed. You reach out tentatively and run your hand along her ass. It's still mostly exposed by the one-piece, so you're finally able to touch her smooth skin. You feel goosebumps raise on her skin, but she doesn't stop you.

"I want you," you hear yourself saying as you stroke her ass. "Right now."

She looks back up at you. "Now? Here? What if someone comes downstairs?"

A good question, you think to yourself.
