Baby-faced boy <Nurumayu>, with his shy smile and voluptuous chest, appears in a solo shoot. Shame and perverse acts intertwine as a remote-controlled vibrator is inserted into his anus, leading to exposure on a balcony. Led outdoors in a nearly naked bondage outfit, <Nurumayu> curls his body in embarrassment, yet undeniable arousal begins to surface. As erotic acts continue—urethral vibration, anal licking, spitting into a cup followed by kissing, and anal intercourse—he gradually melts into ecstasy, climaxing beautifully and intensely in this humiliating training sex session.
