Kouta, a timid university student is tasked with tutoring the outgoing yet dense Chieri to help her get through her exams. However, they couldn't be more different. Find out what hijinks ensue in Oral Lessons With Chii-chan!

"Heya, Kou-chin. You should totally, like, tutor me!"

It was the Saturday right after exams. Summer vacation was right around the corner.

Muroto Kouta, who was living on his own due to complications with his family, encountered his gyaru classmate, Shiina Chieri. And Chieri, known to her friends as Chii-chan, was casually sucking on a popsicle at the convenience store near his apartment.

Chii-chan's a girl who lets her titanic tits, plump thighs, and meaty ass shake with every single step. She flashes her panties like second nature and oozes so much sex appeal that she ruins the grades of any guy sitting next to her in class.

Since she's got the body of a goddess and a fun-loving, ditzy personality, there are all sorts of rumors about her. Some say she's got an older sugar daddy. Some say she supports herself through prostitution. Some say she's an insatiable glutton who's dined on a thousand virgin cocks.

And now, it's Kouta's job to tutor her at his apartment every day after school. He gets to spend some quality alone time with a tanned gyaru who has a body so smoking hot even god would get a boner!

"I've got a boyfriend, so we, like, can't go all the way, buuut..." Chii-chan licks her lips with a lustful smile.

"Kou-chin, since you're, like, totally helping my grades not suck... maybe I'd be willing to suck on something else"
