Secret Training

Ain't nothing wrong with taken the girl you been so mercilessly Fucking, out on a nice relaxing date every once's in a while, is there? What a good kid.

Ah yes, vanilla filled "Secret training" with a 'demon' teacher! Lovely.
Also, for some reason her facial expression on the bottom left panel of page 4...I really liked.
Great ending though. Yes, of course, nothing like a great 'reward' to motivate the hell out of a Hentai Protagonist. Works for tests and competitions alike.  Also there's nothing wrong with a normal date. Those can be quite nice and vanilla filled too. Unfortunately we don't get to see it, but I'm sure even a normal date can have a...happy ending, so to speak.

Get you someone that can do both

I cant get enought of the lusty P.E. teacher trope when done properly

That ending was so wholesome, this dude is A-OK.

Oh my god, that got so wholesome at the end. I love it.

See "the beast' become unleashed in Tamura-kun ... and it seems it's the way Randou-sensei likes it (the lucky bastard ... GRR)! And possibly, the aquarium date was merely a prelude to (*cough-cough*) a later session best described as: "Jungle Boogie"!

APPROVED!

"I'm gonna work you to the bone!" Yes. Yes, I'd wholehearted love to have you work on my bone.

After the aquarium date, he took her to love hotel and confirmed the shape of her pussy maintained that of his dick.

I†˜ll take two secret trainings please! And I have this coupon for a secret training secret wife...
