A sultry Spanish sister finds herself alone with her brother, the tension between them palpable. She's been feeling his gaze on her, his desire for her. She decides to give in, to let him have what he wants. She leads him to the couch, her hips swaying enticingly. She straddles him, his cock already hard and ready. She grinds against him, teasing him, before finally taking him inside her. She rides him slowly at first, then faster, her moans filling the room as he grips her ass, pulling her down onto him. She can feel his hot cum filling her, marking her as his.
