This 25 year old will go to school pretending to be her truant younger cousin! While she can handle going to class, she has trouble following all the showy pretenses of high school life and ends up in a tough spot, forcing her to take refuge in the nurse’s office when all of a sudden Kanie, a teacher, greets her by saying, “Aren’t you Hana Natori?”, which totally blows her cover. In a surprising turn of events, it turns out that Kanie was a former classmate of hers back in high school! Moreover, without any warning he asks her, “do you know what to do to keep a man quiet?” and starts kissing her deeply, pushing her down in the process! With secrets piling up on one another, there’s no running away!

“I suppose I can keep your secret.” Kanie claims he will work with me to hide the fact that I’m attending school in place of my cousin. After we did all that lewd stuff, he affectionately patted me on the head and now my heart won’t stop pounding! What’s more, that night I got a surprise call from Kanie. He said he’d train for the athletic festival with me, but that would mean the two of us being alone together after school!

“We were doing stretches in the athletic storage room and… wait, that’s not right!” Kanie is working out with me in preparation for the athletic festival. After our workout, he helps me stretch, but while he was touches me, I accidentally make some weird noises! He accuses me of leading him on, and no matter how much I squirmed I couldn’t resist or run away… It was just the two of us, alone after school—I’m so hot and sweaty, I feel like I’ll melt away…

“Today you aren’t a student, so I won’t stop halfway.” At our class reunion, where there are no other students or teachers around, we meet as fellow 25-year-olds. It started out as an ordinary evening, but took a sudden turn when I was grabbed by the wrist and lead out of the assembly hall! In a private toilet stall he pulls me close and starts kissing me… Even though we’re supposed to be at the class reunion, he can’t keep his hands off me. But then, all of a sudden, we’re no longer alone in here!

Hana’s heart races as Kanie stares at her. With a serious expression, Kanie says, “Skirt length, makeup, hair… all against code.” “What?!” That’s right, this is a dress code inspection. Hana, summoned for punishment to a prep room after class, explains that she is only dressed this way to look like her cousin Kaho. Nevertheless he asks if she intends to disobey a teacher in a seductive voice and draws closer… After they do it, Kaho looses something important! What could it be? You’ll have to watch to find out!

“W-What do I do? I’m not wearing any underwear, and then this happens!” Hana is corned behind the gym, called out there by Aida. He is about to grope her butt. Hana is in quite the pinch! At just that moment, Kanie appearers from behind…

She agreed to be tutored, but never imagined the place would be Kanie’s apartment! Hana is tense with apprehension at being close, and at having him rest his hand on her back. There’s no way she can study like this! Moreover, it’s gotten late, and it looks like she’ll be staying over!

You said we wouldn’t do this kind of thing today!”—Hana is spending the night at Kanie’s after staying up late studying. Just out of the bath, it seems the cloths she borrowed are too baggy! Her collarbone and boobs are licked mercilessly and she is pushed down onto the bed…
