In this intense, unscripted encounter, a muscular art model thinks he's in for a usual casting session. But Mistress Red Herring has other plans. As he poses, she sneaks up behind him, lubing up her dominant hand. He tenses as she presses against his tight hole, then relaxes into the unexpected pleasure. She starts slow, working her way in, but soon she's pounding his prostate, making him moan and squirm. He takes it like a champ, his ass stretching to accommodate her skilled fist.
