El Pelon's sleep is shattered by a warm, wet sensation. His step-sister, La Flaca, is under his sheets, her mouth full of his hard cock, her small tits pressed against his legs. She moans, taking him deep, her skinny body writhing. He watches, mesmerized, as she starts to fuck him, her big butt shaking, her perfect tits bouncing. She's dirty-talking, telling him how much she loves his big cock, her pussy dripping, ready. He can't help but cum, hard, his load covering her pussy, their taboo lust complete.
