In the quiet of her dorm room, a university coed, uninhibited and curious, explores her body's desires. She's a buena puta, a good girl by day, but by night, she's a sexual explorer. She teases her nipples through her thin shirt, feeling them harden, then slips a hand beneath her skirt, rubbing her panties, already damp with anticipation. Her fingers find their way inside, mimicking the thrusts she imagines from a lover. She's a student of pleasure, learning, growing, masturbating with abandon, her moans echoing in the empty halls.
