Sister seduces brother for a quick romp before mom's return

College life can be quite stressful, but when this young man walks in on his supposed sister sunbathing on the roof, he figures she's just trying to get his attention. However, things take an unexpected turn when she reveals her true intentions. She's been craving his attention and now she's ready to give him a show he won't forget. She starts by teasing him with her perky little tits, before slowly removing her bikini bottoms to reveal her shaved pussy. He's taken aback at first, but then gives in to her seduction. She eagerly takes his cock in her mouth, sucking it with enthusiasm before mounting him. They have a quick and intense fuck session, with him taking her from behind and then letting her ride him in a cowgirl position. The encounter ends with him cumming inside her, just as their mother walks in, setting the stage for a potential future encounter with the mother-in-law.
