I'm a college student living together with my girlfriend in Tokyo. One day, I accidentally made eye contact with a woman across the way in a luxury apartment, changing into her underwear. She was stunning, big-breasted, with a perfect figure and an alluring mature charm that my girlfriend didn't have, instantly captivating me. Soon, peeking into her room became my daily pleasure, and each time I saw her, my excitement grew. One day, as if she'd discovered my spying, she began deliberately exposing her lingerie and naked body, seductively smiling at me as she tempted me. From then on, her teasing escalated—she started showing me her masturbation and even sex with other men. Then one day, while my girlfriend was away, she came over to my place, inviting me to drink together. Whether it was the alcohol or intentional, she stripped down to her lingerie and began seducing me. The mysterious beauty from the apartment across the way, who knows me when no one else does, tempts me with her sensual lingerie, masturbation, and sex with other men. Overwhelmed by her overflowing pheromones and erotic naked beauty, I lose control and climax again and again under her experienced, skillful movements. Until my girlfriend returns, I'll indulge in wild sex without restraint. No man could ever refuse! For a few stolen hours while my girlfriend is away, we secretly meet between our rooms in this reverse NTR affair.
