Hidden in her room, the teen dips her hand into her panties, fingers dancing around her clit. She's lost in thought when her brother walks in, catching her red-handed. Embarrassed, she tries to shoo him away, but he's intrigued. She offers him a show, and he watches as she spreads her legs, revealing her glistening pussy. She fingers herself, moaning, until she can't take it anymore, cumming hard with her brother watching.
