I got a job and moved to Tokyo, and one day I noticed a cute high school girl coming in and out of the room next door. The man who lives there said he didn't have any relatives or friends... I knew it was wrong, but when I peeked in, the high school girl started having sex with the man! She straddled him, teased his nipples, and shook her hips in a cowgirl position! Damn, I'm jealous! But unfortunately, she found out... I was in a dangerous and desperate situation!?
