"Gostosa," Michelle whispers, her eyes locked onto her brother's throbbing cock. They're alone, their parents away, and the house is silent except for their ragged breaths. Michelle, dressed in a tiny top and shorts, straddles her brother, feeling his length through his pants. He's hard, ready. She grinds against him, her pussy dampening her shorts. "Fuck me," she begs, her voice barely a whisper. He complies, pushing her down onto the bed, pulling her shorts aside to plunge into her wet, waiting cunt.
