Maria, in the throes of teenage hormones, retreats to her room for some private time. Her boyfriend's been distant, and she's craving release. She strips off her shirt, letting her pert breasts free, and slides her hand into her panties, finding her clit already wet and eager. She bites her lip, moaning softly as she imagines her boyfriend's touch. Suddenly, her little brother bursts in, catching her in the act. Embarrassed, she quickly covers up, but the sight of his wide-eyed shock sends a thrill through her. She decides to tease him, putting on a show, rubbing her breasts and fingering herself until she cums, leaving him breathless.
