She lets you play with her tits.

With one hand still stroking my cock--which was slowly getting closer and closer to exploding--Traci reached behind her and unhooked her lacy black bra. She slowly slid it forward and off her shoulders, continuing to jack me off as I stared at her newly-naked tits.

I’d been right before: they were great tits, each a solid handful in size and perky on her slender torso, the skin smooth and creamy, and topped with surprisingly large pink areolas. After giving me a good look, Traci let go of my dick and ran her hands over her breasts, rubbing and lightly squeezing them, occasionally pinching a thick nipple and moaning softly.

“Your turn, Mike,” Traci said, her voice husky. She grabbed my hands and pressed them to her breasts. I squeezed her jiggling globes eagerly, beginning to maul them passionately like I had done in my previous high school hookups. But faced with my relative inexperience, unlike the girls I’d groped in the past, Traci was way too serious about getting off to put up with any well-intentioned clumsiness.
