Sneak a peek at Sarah's ass.

“Getting a good look, you little perv?”

You look up and realize that all three women have turned their heads back towards you without straightening up. You start stammering, trying to come up with an excuse that will convince Grace not to kick you out and never talk to you again, but nothing’s coming.

After what feels like at least thirty full seconds of stuttering, Sarah giggles. “I’m only teasing you. Honestly, it’s my fault for shoving my ass in your face. Sometimes I forget how well equipped I am. But don’t worry, I’ll try to be more considerate in the future.”

Somehow your mouth as stopped working, which might be for the best since all you can think to say is "if you want to be more considerate, you’d shove your ass in my face more." Probably best not to press your luck, though.

You all grab drinks and climb into the hot tub. You’re particularly excited because the jets will help hide your erection. The four of you chat for a little while, talking about your lives, making jokes, you know, the usual friend stuff. After a little while, Sarah’s phone chimes from where its sitting on the ground outside the hot tub.

Sarah can’t quite reach it from where she’s sitting across from you, so she has to stand up and turn to reach it. This gives you yet another fantastic view of her ass as she’s bending over. You absent-mindedly start rubbing your cock through your pants, knowing the hot tub’s jets will hid the motion.

Luckily, she doesn’t catch you looking this time – and somehow neither do the other two – as she finishes replying to whatever message she received and sits back down.

But just because she didn’t catch you looking doesn’t mean you weren’t caught. Because right then, the jets decide to cut out. “Damn it, what’s going on now?” Grace says. She starts to stand up to go see what the problem but freezes, staring down at you. You look down and see a visible tent in your pants.

Too late, whatever issue caused the jets to stop for a moment resolves itself and the jets come back on. Grace already saw, though. The others likely did too.

“So, uh,” Sarah says. “Looks like you’re having a good time, huh, John?”

“I’m so sorry,” you stammer. “I-”

“No, really, it’s fine. It’s good, actually. It’s a perfectly natural reaction, I just… I didn’t realize you saw me that way. I kind of like it, though.”

The other two girls share a look. “Are we in the middle of something here?” Tori asks.

Sarah flushes, suddenly remembering that there’s an audience. “I don’t know,” she mumbles.

Grace and Tori share a look. “I think we might be,” Grace says. “Hey, if you two want to go take my bedroom for a little bit, don’t let me stop you.”

“What?” Sarah says. You have to admit, you’re caught off guard yourself. You knew Grace and Tori were more open about having sex, but this was more than you were expecting.

“Seems like a simple question to me,” Tori says. “Do you want to take John up to Grace’s bedroom and fuck?”

Sarah’s face goes even brighter red, and she starts stammering. Grace shoots you a look that says answer the question, idiot.
