2nd grade junior high school kid, Shirai Sachi (14), gets tutored by the beautiful and easy-going woman, Chabatake Nana (21). Although she slacks off when tutoring, actually not helping his studies at all, for Sachi it's all fine and dandy. Being alone together with a hot, older woman in his own bedroom, frolicking around, unintentionally revealing neathage, or just lying down on his bed, with her bare long legs or the cleavage of her ample breasts in perfect view. Who could complain? It's an adolescent boy's fantasy fulfilled!

It is a very fun manga to read but i was very sad when i found that the manga was only translated till the 45 chapter, the rest of the manga I have seen in raw/japonese so i didn't understante all the story but the end is so weak, im so frustated that i can't read the rest of the chapter. I hope someone pick it up so we can read it but the manga is so old and till now nobody decided to translated so i start losing hope, i recommend read it but be ready for falling in despair because you only can read more

This manga's strong points: Ecchi scenes, Moderately funny
This manga's weak points: Plot and character development

If we could all agree to be honest for a minute, I think we could agree that we're here searching for a nice little ecchi manga with a sexy nee-san being a tutor for a awkward middle schooler who is rapidly awakening to the idea of recreational sex. If so, I can tell you right now that this manga does deliver the scenarios and the artwork with fairly good execution.However, I came for the ecchi scenes and was genuinely surprised by how much more I enjoyed the humour.

Yes, this is read more
