Stepmom Susan stumbles upon her stepson, Machine, lost in his own world, vigorously stroking his hard cock in the bathroom. Caught red-handed, he freezes, his face flushed with embarrassment. Susan, shocked and disapproving, scolds him, "You're just a perverted boy, aren't you?" Her words sting, yet Machine can't help but feel a thrill, his cock twitching as he's forced to confront his taboo desires under her stern gaze.
