In a secret corner of the gym, Shely81, clad in tight yoga pants, stretches, her cameltoe prominent. Her stepbrother, hidden, watches, his cock tenting his shorts. He pulls it out, stroking it, fantasizing about her fat, puffy pussy. She catches him, and he quickly hides, but his cumshot on her gym pants gives him away. She's furious but also aroused, her pussy mound throbbing with desire.
