A fit, young stepSister discovers her stepBrother's workout routine and decides to join in. As they sweat together, she can't help but notice his growing bulge. She suggests a cool-down stretch, using it as an excuse to rub against him. He responds by pushing her against the wall, kissing her deeply. She moans, guiding his hand to her soaking pussy. He fingers her, then she drops to her knees, taking his hard cock in her mouth. She rides him hard, her tight teen pussy gripping his length as she comes undone.
