Flunk the Written, Ace the Practical

Did this guy really put a dildo causally into his mouth?

I would describe that teacher as "Moe AF"

"Kazami-chan Sensei.... I've loved you.... for as long as I can remember... which was yesterday...."
:) My personal edit.

Who does not love a Lolita with big tits

Oh, god, is she adorable... ^_^

Can i nominate page 21 top right panel for best in show?

If his friends thought they were jealous before.....wait til they notice how much "extra time" sensei is putting into him.

...Taste testing the dildo? Can't think of any other reason he'd stick it in his mouth.
Still, you find out your cute teacher was masturbating all the time during supplementary classes with you, so the logical thing to do is just offer to take its place, right?
Great ending though. True, she doesn't need it anymore, now that he's there. Also, seeing her in just the Y shirt (Would have been better without the underwear but still lovely) is really nice.
Great art too. A sweet Vanilla release that's just really nice and deserves to be read.
