In the heart of Brazil, cousins Ana and Bino find themselves alone in their grandma's old house, the Casa do Bino. As they reminisce about their childhood, Ana playfully teases Bino, making him blush. Later, Ana catches Bino masturbating in the bathroom, his thick cock hard and ready. Embarrassed, Bino confesses his long-suppressed feelings for her. Ana, equally aroused, admits she's always been attracted to him. They share a passionate, taboo kiss, their hands exploring each other's bodies hungrily. Bino's cock throbs as Ana guides it inside her, filling her tight pussy as they fuck quietly, their moans echoing through the empty house.
