25-sai no Joshikousei 04 English Sub

As predicted at the end of the previous episode, their high school reunion was approaching and both were going to attend. At the reunion, some people mentioned how different Kanie was from back then. He meets Hana and ends up staying with her the whole time and talking to her. She starts to get nervous when she’s around him, but he tells her that if she starts behaving suspiciously, people will know something is wrong (seeing a girl nervous with a guy would surely lead anyone to logically conclude that it must be because she is posing).

Kanie is bored at the party and grabs Hana and takes her to the bathroom in which he does kinky Hentai things to her. While they are having sex, they hear people walking down the hallway and Kanie tells him to be quiet or they will be found out. They hear the two guys talking. While listening to this, Hana also hears one of the guys mention how much Kanie liked Hana, even in high school, so it makes sense that they are dating now. Hana is surprised by this, but Kanie then starts doing even more things to her to try to distract her. 

25-sai no Joshikousei is about a grown woman named Hana Natori who now has to replace her absent cousin who is in danger of failing in school. Hana is not the strong type and relents, being a girl ten years younger than her. However, when she thinks she is safe, a teacher pulls her aside and tells her he knows who she is! Shocked, she learns that her teacher was her own high school classmate. He agrees to keep her secret as long as she comes to him for « private lessons ». Can she bear it?
