Sandra, a curvaceous Peruvian woman, sits in her small apartment in Callao, her mind wandering to her secret lover, Santa. She's a 'puta' in the eyes of society, but she doesn't care. She unzips her skirt, letting it pool around her ankles, and leans back, spreading her legs. Her fingers trace the edge of her panties, feeling the dampness. She pushes them aside, exposing her glistening pussy, and begins to rub her clit in slow, deliberate circles. Her moans fill the room as she fantasizes about Santa's skilled tongue and thick cock. She's so lost in her pleasure that she doesn't hear the key turning in the lock.
