I half expected some delinquent BSS stuff out of this but it's ridiculously sweet. A girl turning herself into a pervert out of curiosity (with consent) is adorable.

That Yamada girl on the last page needs a sequel of her own.

Hatsuyasumi seems to be damn good at incorporating character development along with the required higher than normal page counts.
I hope they can keep this style up as their career grows.

This was great, that girl is thirsty, i wish there was more chapters with them.

Also, big kudos to Yamada who knew about what was happening but kept quiet, she (he?) deserves some love as well
