[Asai Makoto] OneShota Sports Gym!!!

Yuuki-kun's quiet errand to return a classmate's forgotten clothes takes a wildly unexpected turn when he stumbles into a private locker room and discovers his voluptuous gym instructor fresh from the shower. With a playful smirk and a towel that does little to hide her dripping, ample curves, she questions whether he prefers doing at the girl's place before pinning him down for an intense, sweat-soaked session that leaves him utterly spent. As the story closes, she finds him practicing soccer later and teases about a promised match, her top clinging tightly to her enormous chest while the tension between them continues to build.
