Spanish cousins Armando and Maria, drawn together by familial bonds and sexual curiosity, find themselves alone in the house. Their initial conversation is innocent, but the air grows thick with tension as they lock eyes. Maria's gaze falls to Armando's crotch, his bulge growing evident. She licks her lips, and he takes the hint, unzipping his pants to reveal a thick, throbbing cock. Maria, intrigued by the taboo, tentatively touches it, then leans in to take it into her mouth. Armando moans, his hands tangling in her hair. He pushes her gently back onto the couch, lifting her skirt to reveal her wet pussy. He teases her with his fingers before replacing them with his cock, fucking her hard and fast. Maria gasps, "Fuck me in the ass," surprising them both. Armando hesitates, then spreads her ass cheeks, pushing his cock into her tight hole, pounding her until they both climax, their cries of pleasure echoing through the house.
