Let her ride you until you cum.

You're too close and this feels too good. You don't say anything about your impeding orgasm and she continues to ride you with increasing fervor. Your orgasm hits and it hits hard. You let out a loud guttural groan as you let loose and plaster her insides causing her to gasp and moan at the feeling.

She doesn't show you any mercy though and continues to ride until she hits her own climax a moment later, your cum working as lube. Her nails dig into your back as her whole body convulses with pleasure. She cries out and you're certain that the others have heard what's going on by now. If they slept through yours, they can't have slept through hers, could they?

Grace finally slows down as she comes down from her climax and more-or-less collapses into you, her chest heaving and pressing her tits into your chest with breath. Once she's caught her breath, she pulls you in for a deep kiss. "That was fucking hot," she says. "Could have used some warning before you came, though," she adds with a giggle.

She's not the only one who giggles.

You both realize this as you're looking into each others eyes in post-sex bliss. You see her eyes widen and you both whip around and see Sarah and Tori poking their heads around the corner. They seem to have traded their bikinis in for pajamas.

"Oh my god!," Tori says as she tries to cover herself. There's not much she can do, though, since she only has two hands and she still has your softening cock inside her. "How long have you been watching?!"

"Not long, unfortunately," Tori says. "We heard John and came down to see if he was jerking it or something. I was kind of hoping... But anyway, the show was great." She winks at Grace.

She seemed like she was about to say something interesting before trailing off and you're not going to let her off that easily. As Grace grabs and blanket and wraps it around both of you to cover up - and pulling herself off of you in the process - you say, "What were you hoping for?"

"Well..." Tori says shyly. "I can't speak for Sarah, but I was kind of hoping to find you alone so that I could, you know, offer to help you out."

You idly wonder what might have been if she'd walked in on you before Grace. Then you realize that maybe you don't have to wonder. You say, "Well, I'm sure I can get hard again if you wanna do something."

The room is quiet for a minute before Grace says, "That's certainly bold, propositioning a new girl while I still have your cum in me." Luckily, it sounds like she's more amused than angry.

Still, you don't want to ruin things with Grace, so you say, "I mean, as long as you're fine with her joining us."

Grace smirks. "That's better, boy." She looks over at Tori. "You up for it? I can go again."

Tori lights up. "I was hoping you'd say that." She walks into the room and begins stripping down. Her body is as gorgeous as you could have imagined. When she bends over to slide her pajama shorts off, you cock starts stiffening again even though you've just cum.

"What about you, Sarah?" Grace asks. "You're more than welcome too."

She hesitates for a moment, and looks like she's about to bow out. Then her eyes glide up and down Tori's body and you can see the desire in her eyes. She doesn't reply, but she does step into the room and start sliding her own PJs off. If Tori gave you a partial, seeing Sarah's body gets you fully hard again.

"I guess there's no need for this anymore," and you pull off the blanket covering you and Grace.

"So," Sarah says. "How do we start?"
