Sleep An Adult [English], by Onapan
Boy side: I’m alone with the girl to whom I want to confess, at last! But… oh no, she fell asleep! I think I’ll undress her, caress her, and test if she’s really sleeping by poking her with my dick.
Girl side: I’m alone with the boy I like at last! But… how to confess? I think I’ll do better: pretend to be asleep, and catch him with his dick out, from there on it will be simpler.
Hentai logic at its finest ¯\_(ツ)_/¯
Mind you, other than that, it was pretty good. Sadly whiteout censored, true, but the girl is cute, her genuine thirst for dick is praisable, and everything is better when the girl wears a hairband :3
(Side note, I very slightly retouched the images. Stronger contrasts, darker darks, fainter light pixel pollution.)
Thanks a lot to N04h and Herzer for this release!
By the same artist, I also share Kyou Koso Nukou Ne Kanjou Sen.

And from all indications, their classmates and friends (a-hem) “helped close the deal”.
That’s pretty good when the whole class is your wingman . . .
