[START-318] [Completely subjective] The cheerful dancer girl who is like a little brother to my club and is okay with dirty jokes only shows me a cute smile, but when I noticed, I ended up ejaculating 10 times in a week. Mei Miyajima (Censored)

Mei is a cheerful girl who is like a younger brother to me and is in the same dance club. She has a mischievous personality and is always talking about dirty jokes without caring about others. After a drinking party, we were playing around as usual and when I played a prank on Mei who was half asleep, we ended up having sex...I couldn't contain my feelings for Mei who I usually don't show to others, and before I knew it, I had ejaculated 10 times in a week.
