This adult man's nipples are extremely sensitive, and dominant Mai Shirakawa toys with them mercilessly. She makes him wait before touching them with her long tongue, then keeps teasing with her tongue and fingers until his cock is rock hard. She eagerly sucks him, gives him a long blowjob, and goes right back to torturing his nipples afterward. The stimulation is so intense that he cums almost immediately in missionary, leaving Mai complaining that he finished too fast. Let this be a warning about teasing sensitive nipples too much.
