BACJ-170 The out-of-place princess who came to the otaku club seduces me with her panties. She shows me her friend having sex with me right in front of me, and I masturbate to a humiliating ejaculation. Masako Rina

Today, as always, I was playing games with my best friend in the club room. But suddenly, my classmate Rina came over... She asked me to go to her house and drink, what's up with this girl... and she even showed me her panties in a sexy way... Grrrr. I don't know where to look... but then I realized, she's trying to seduce me!? Of course she is, she's been staring at me the whole time! What's going on?! Just when I thought she was making fun of my modest son, she's giving him a sex lesson using the playboy Ryuta as an example. What's going on all of a sudden, what's going to happen to my student life!?!?
