Pregnant stepsister gets creampied in school shower

A pregnant stepsister slips away to the school showers, hoping for privacy, but her boyfriend's brother follows her in. He pushes her against the wet tiles, his hands roaming over her swollen belly before sliding lower. The hot water pours down their naked bodies as he lifts her leg onto his shoulder for easier access. He thrusts deep into her, the contrast between her pregnancy and the act heightening the taboo thrill. She bites her lip, a wave of relief washing over her as he fills her up completely.
