On her ass.

You pull out and grab your cock. With two strokes, jets of jizz flies hits her ass and back. "Fuck, Sara!" you roar.

Sara tosses her hair to the side and looks over her shoulder. "Your hot sticky cum feels so good on my back!” She says, wagging her ass.

“You guys are so hot!” You hear a voice behind you say. You spin around and see Jen and Alice giggling. Jen is holding her phone up, apparently she’s been recording the two of you.

"Oh my God!" Sara gasps. "How much did you record?!"

"Enough," Alice smirks. "We heard you yelling about how big he is, so we had to check it out for ourselves." The brunette looks you up and down. "Damn. I'm a lesbian and even I'm impressed how big your cock is even when it’s limp!"

"Listen, you may have noticed that I’m covered in cum," Sara says, winking at you. "I need a shower now."

"Oh, I’ll help scrub your back!" Jen volunteers.

"Haha, sure!" Sara giggles.

The two girls give you sly glances as they walk down the hall towards the bathroom, leaving you alone with your naked brunette roommate.
