Under the watchful eyes of their family portrait, the cousins' secret rendezvous begins. The brother's hands tremble as he unbuttons his cousin's dress, revealing her lacy bra and panties. He kisses her neck, his hands cupping her breasts, feeling her nipples harden. She turns, their lips meeting in a passionate kiss. He picks her up, carrying her to the bed. She giggles, her legs wrapping around him. He lays her down, his hands caressing her body, his fingers hooking into her panties, pulling them off. He spreads her legs, his tongue finding her clit, licking and sucking until she's writhing. Then, he stands, unbuckling his pants, his hard cock springing free. She reaches for it, guiding it to her ass, her eyes locked with his as he enters her, filling her completely.
