I'm a college student, and I moved to Tokyo with my girlfriend and are living together. One day, I happened to see a woman changing in her underwear in the room of the luxury apartment across the hall, and our eyes met. The older woman was beautiful, had big breasts, a good figure, and was full of adult sex appeal that my girlfriend didn't have. From that day on, I became curious and peeking into the older woman's room became my enjoyment. One day, as if she knew I was peeking, she showed me her underwear and naked body and smiled seductively. Her seductive temptation escalated, and she started showing me her masturbating and having sex with another man. One day, while my girlfriend was away, the older woman came to my room and invited me to drink together. Whether it was the effect of the alcohol or intentional, she suddenly appeared in her underwear and began to seduce me. The mysterious beauty in the room across the hall, who bewitches me, the only one she knows. She seduces me by showing me her seductive lingerie, masturbation, and sex with other men... I couldn't control my reason in the face of overflowing pheromones and erotic beautiful nakedness... I cummed again and again with the experienced adult's too lewd hip movements. Let's enjoy sex to our heart's content until she comes back... No man can refuse! A few hours while she's away... Secret meeting and affair in each other's rooms, reverse NTR.
