on her back

You pull your cock out and shoot streams of hot jizz on her back. "Yeah, baby!" she screams as she feels it landing. "Now, take your finger, clean my back off and feed it to me!" You start to comply, and at the same time her roommate, Julie, walks into the room. "Holy fuck! What's going on here?" she exclaims.

Now, Julie is about 5'10" 140 lbs, wavy brown hair down to her ass, dark brown eyes, and sporting a nice set of 34B's.
