Kakushi Dere Episode 3

Taiki confesses to his highschool crush, Mihashi Chizuri, not knowing about a nasty rumor
between her and Ikeda-sensei. After hearing about the rumor and confronting his
now-girlfriend about it, Taiki is relieved to know there was no truth to it.

The couple then have sex for the first time, although throughout the episode Taiki had been
fantasizing about his girlfriend in various sexual situations.
