In a cramped, dimly lit closet, I push my sister against the wall, her breath hitching as I growl, "You're mine, putinha." She moans softly, her body betraying her, pressing against my hardness. I narrator, guiding her hands to her breasts, pinching her nipples as I grind against her. Her moan echoes in the tiny space, fueling my desire. I slip my hand under her skirt, finding her wet, ready. She gasps, "You're so bad," but her hips move in rhythm with my fingers, begging for more.
