Ecstudy!

Yes!! More of Oohira Sunset's stories. Hope we'll get a book soon!

HOTTEST STUDY SESSION EVER! Her being a osananajimi is icing on the sexy cake that is Ichika.

"I AM the toilet.❤"

Finally, a working solution for educational deficits I can really get behind!!! Ridiculously sexy student, insanely lucky tutor. This is the true definition of "performance enhancing"...!!!

I truly do find her skill to be rather impressive, never knew that sex can dramatically improve someone’s focus. Great story!

Ah yes, the offering of a 'reward', never fails to motivate someone to success.
Smart girl though, he said she couldn't do anything if she failed, but he never said anything about doing anything DURING the test indeed!
So cumming makes her smarter for a short time, eh? Interesting. He makes a fair point at the end, regarding not being able to have sex while she does her tests, but...
I mean, it's Hentai. I'm sure there is a way if you would just try.

Who would have thought that her IQ would go up by fucking only hentai!

Well you can use a vibe or some type of stroker dong dildo

Maybe it’s just me but Oohira Sunset’s art looks a lot more refined here.

Is this teaching method "the carrot or the dick?"

Can't help but think 'Okaa-San' *koff-koff* "KNOWS" (sometimes teens tend to forget parents were their age once upon a time).

Nonetheless, maybe Okaa-san figures it's an equivalent exchange for getting Ichika to be a diligent student. Do Your Best, Ritsu-kun ... you Lucky Bastard (GRR)!

"APPROVED!" ✌
