I'm a college student, living with my girlfriend in Tokyo. One day, I saw a woman changing her clothes in her underwear in the apartment across from ours and our eyes met. The lady was beautiful, had big tits, and a great figure, with a mature sex appeal that my girlfriend lacked. From that day on, I started to sneak into my sister's room. One day, she seemed to know I was watching and showed off her underwear or naked body with a seductive smile. Her provocations escalated, and she started masturbating in front of me or bringing men back for sex. One day, my sister came to visit me in my room while her girlfriend was out and invited me to drink alcohol together. Whether it was due to the alcohol or on purpose, she suddenly stripped down to her underwear and started seducing me__. The mysterious beauty in the apartment across from mine that only I know about. Seductive lingerie, masturbation, or sex with other men to entice and seduce... Overflowing pheromones and erotic naked beauty drive reason away... Experienced adult's obscene hip movements make you cum again and again. Let's enjoy sex to the fullest until she comes back… No man can refuse! While the girlfriend is away for a few hours... secret trysts in each other's rooms, reverse NTR.
