London River, the sultry stepmother, finds her son's idiocy strangely arousing. She corners him in the living room, her eyes gleaming with lust. 'You're such a stupid boy,' she purrs, 'but you're my stupid boy.' She strips for him, her ample assets spilling out, beckoning him. He hesitates, but she's having none of that. She grabs his cock, stroking it until it's rock hard. Then, she rides him, her pussy swallowing his length, her tits bouncing as she fucks him rough and raw, just like the naughty, taboo mom she is.
