Late at night, alone in an empty gym... sweating profusely, a tempting feast of flesh, F-cup breasts, intimate and close-knit private sex. (FSDSS-982)

The 24-hour gym gets less crowded late at night, but it's still a good place for those who want to focus on their workout. Today, a young man started working out, and at the same time, a woman came in and started doing stretching exercises. Her tight pants clearly showed the shape of her buttocks, and her top was almost revealing her breasts. As I was watching, she suddenly touched my penis, climbed on top of me, and seduced me on the machine. On the mat, she inserted my erect penis, penetrated deeply into her vagina, pressed herself against me, and thrust violently. After 3 a.m., there might be some horny women, so it's best to stay away from the gym...
