My wife and I live together in our home when her mother comes to visit from out of town. She's been scouted as a lingerie model, convinced my father-in-law to agree, and arrived to prepare for an upcoming audition in one week. Secretly, she begins practicing by wearing flashy, seductive lingerie designed to allure men. Catching sight of her like this, I can't help but get aroused, my erection becoming impossible to ignore. Noticing my reaction, my stepmother takes the opportunity to approach me—dressed in even more provocative lingerie—and asks me to do a test photoshoot with her. The atmosphere shifts into something surreal, crossing the boundary of ordinary family life.
