Meet Yumi, a stunning 29-year-old wife and accomplished flower arrangement master, who's never known the touch of another man until today. She tentatively steps into her tryst, her heart pounding as she sees her lover for the first time. He's a towering, muscular stranger with an intimidatingly large cock. Yumi's eyes widen in anticipation and apprehension as he approaches, his eager hands already unfastening his pants. He pushes her gently onto the bed, his massive member throbbing as he rubs it against her wet, married pussy. Yumi gasps, her body arching as he enters her, stretching her tight walls. He fucks her hard, his hips slapping against her ass, his cock thrusting deep inside her. Yumi's cries fill the room as he pounds her, her body writhing in ecstasy. She can't believe how good it feels, how different it is from her husband. He pulls out, his cock glistening with her juices, and strokes himself, releasing a torrent of cum onto her stomach and pussy. Yumi looks down at her body, marked by her lover's seed, and feels a surge of guilt, but also a primal satisfaction.
