[NTRH-027] I was cuckolded even though I had a girlfriend next to me, and I was seduced by showing off my overflowing sex appeal and lewd lingerie and bewitching me.

As a college student, I moved to Tokyo with her and live with her.
One day, I saw a woman changing in her underwear in a room in a luxury apartment across the street and our eyes met.
The older sister was beautiful, had big breasts, had a good style, and was full of adult sex appeal that she didn't have.
From that day on, I was curious about it and looked forward to looking into my sister's room.
Then one day, my sister seemed to know that I was peeking at her, and she smiled glamorously at me, showing me her underwear and naked body.
Her temptation to show off escalated, and she began to masturbate and bring in men to show her sex.
Then one day, my sister came to my room while she was away and invited me to drink with her.
Whether it's because of the momentum of the alcohol or on purpose, she quietly got into her underwear and seduced me.
A mysterious beauty in the opposite room who confuses me, who only knows her.
Showing off her glamorous lingerie, masturbation, and sex with other men and seducing her...
I can't suppress my reason at the overflowing pheromones and erotic beautiful naked body...
Ejaculate over and over again at the overly nasty hips of an experienced adult.
Let's enjoy sex to our heart's content until she comes back...
If you're a man, you can never refuse! A few hours away from her... Secret meeting affair reverse NTR in each other's room.
