Shishunki No Obenkyou [English], by Meganei
It’s kind of a weird funny share, here, with a girl obsessed with the thought of male penises but not knowing shit about sexual relations. She’ll get practical live sex ed soon, anyway, after a comical relief situation. Around the end the dialogues become weirder, with a reinvention of the “manko” term, it felt WTF ^^;;
Honest warning, I felt ill at ease sharing that one, the girl is borderline too young. I told myself it wouldn’t be the first time, other mangakas have done worse, but, well, here’s for the warning.
It’s been released by Shippoyasha, thank you!
–Update: there’s a second part now, Shishunki No Obenkyou 2!
–Update#2: excellent news, this post has become obsolete!
The present share is now part of a complete 216 pages long volume:
Shishunki No Obenkyou
Perhaps she could just be considered “barely” pettanko. That aside, it was a novel approach to two curious (if not outright horny) teens having their “first time together”.
Curious how you consider the girl to be “borderline” too young, but not the guy, considering they are ein the same class.
Oooooold topic. Underage girls is bad, booooooh, underage boys is less bad

You could say then have to get it hard so it’s a matter of having the will and a body that’s old enough for the deed, stuff like that, but I’m not interested in discussing it for the 299th time
C’mon man, don’t be stingy with the black, bar, onomatopoeia penis; give the girl what she wants.
On another note, there was a movie, Being John Malkovich.
In the movie, the MCs found a portal into the actor’s mind.
Sometimes I look at the pics Oliver selects for posts; and a dread washes over me, thinking of if that portal existed into his mind and witnessing the gooey machinations within.

You don’t want to enter that portal, man, you’ll exit it with scars all over your soul.
The artists here really know a thing about what gets people horny with fantastic hentai artwork. Your words are almost more addicted than image
