Forbidden Affairs Vol. 3: The Stepdaughter. James Avalon, a premier director of porn for couples, helms Sweet Sinner's 'Forbidden Affairs 3: The Stepdaughter'. Struggling writer Nigel Radcliffe (Marcus London) is in search of a muse, and he finds that his gorgeous nymphomanic wife (Dana Vespoli) no longer inspires him. But when his young, tantalizingly naughty stepdaughter Dakota (Carter Cruise) moves in, Nigel rediscovers his love of writing. He can't help but watch as Dakota becomes increasingly rebellious and brings her misbehavior under her stepfather's roof, until the film reaches its climax and the heated Father/Daughter relationship comes to a head. Also starring Erik Everhard, Scarlet Red, Logan Pierce, and newcomer Gavin Kane..
