In the dimly lit bedroom, Chi and her brother, Pê, share a secret, taboo desire. Chi, the younger sister, teases her brother, presenting her petite, firm body and pouting lips. Pê, already aroused, can't resist the temptation. He grabs his throbbing cock, stroking it furiously as Chi plays with her clit, moaning softly. The room fills with their heavy breathing and the wet sounds of self-pleasure. As they reach their peak, they lock eyes, Chi opening her mouth wide, inviting Pê to unload his pent-up lust onto her face. The first shot hits her cheek, and she licks it off eagerly, urging him for more. Pê obliges, covering her face in his warm, sticky cum, marking her as his.
