The step-grandson arrives at his step-granddaughter's house, sweaty and disheveled from a night of gambling. He finds her in the living room wearing a tiny bikini, drinking a frosty beer. She smiles seductively as he sits down next to her, his hard-on already poking through his pants. They move to the bedroom where he rips off her bikini, revealing perfect tanned breasts and a shaved pussy. He devours her, licking her clit as she begs for more. He stands up and pulls down his pants, revealing a throbbing, uncut cock. She takes it in her hand and starts stroking it as he flips her onto the bed. He slaps her ass hard as he pushes inside her, filling her tight pussy with his girth As she moans loudly, her body arching into his, she feels him grind against her, their sweat mingling as they move together in a primal rhythm.
