Carrie asks him to stay

"No...no, you can stay David." Carrie says. She softly grinds against him. "I enjoyed myself so you don't have to leave."

You see David smirk as he removes his hand from the curtain and goes back to playing with Carrie's pussy. You see the clear ecstasy that she feels having him play with her body. Now that it's on full display for you to see, it's even hotter than you imagined.

"Oh, but Carrie, you know what that means right?" He says pulling her in closer to him. "If you let me stay, can do whatever I want to you. You sure you're okay with that? What about your boyfriend?"

For a faint second you see a look of doubt wash over Carrie's face, but then it quickly goes away.

"Like you said, anything past the massage can be our little secret." She moans. She reaches back between David's legs giving long, slow strokes to his cock. You see desire in Carrie that you've never seen when she was with you. She's absolutely transfixed on David in this moment. A part of you wonders if she even remembers that this was set up for you. Right now, looking at her want David more than anything, you don't think it matters what the reason was.

"Good girl!" David says giving her breast one last squeeze. "Then I'm gonna make good on my promise and give you a shower you'll never forget! Go ahead and bend over for me."

Carrie gives David's cock a squeeze then slowly bends forward. Placing her ass up and giving it a little wiggle on his cock to tease him.

"God you have such a sexy body Carrie!" David says slapping her ass and squeezing it. "Admit it, you've had your eye on me for a while. That's why you pretended that the shower was broken huh?"

As he says all of this he's rubbing his bare cock against her ass. You can't believe it, but you're going to witness Carrie get fucked by your roommate. It's a fantasy that you've replayed a thousand times in your head but seeing it happen has you stroking your cock to the point of bursting. In this moment, you want more than anything to see this through to the end.

"I..." Carrie starts, she takes a second to think, "I will admit I did set this up to get you in here with me."

"Ha!" David laughs, "I knew it you're just a dirty slut who finally couldn't handle not feeling what this cock was like!"

Carrie's choice of words were so subtle. Yes, this was planned, but not entirely how David assumed. But, there was something in Carrie's voice. You couldn't help but wonder... had she thought about what David would feel like before this?

"Don't worry babe, you'll finally get your answer! I think you're finally wet enough to take it!" David positions his cock at the lips of Carrie's pussy. "Just tell me when and I'll stick it right in."

Then for a second you see it. Carrie looks over at the door out of the corner of her eye. She looks directly at the crack, directly at you! She knows you're watching! She might have known this whole time!

"Do it David, fuck me!" Carrie says
