## Description
"Hey, Kou-chin. Sorry to bug you but, will you help me study?"

It was a Saturday. There was still a month of summer vacation to go. Due to complicated family circumstances, Kouta - "Kou-chin" - who lives alone meet Chieri - "Chi-chan" - a classmate of Kouta's at the conbini near his house.

Chi-chan oozed sex. Her big tits and lazily protruding ass were a distraction from whatever he was supposed to be helping her with. She had the kind of body that, if you sat behind her at school, your grades would plummet. Somehow or another she was renting her own place. Whether she had a sugar daddy or did the whole "paid date" scene, Kouta didn't know. There were rumors about her, though.

This ditzy kurogal was his benefactor for the summer. Kouta helped her study - though he could hardly focus - and as a bonus he was endlessly visually entertained. He knew Chi-chan had a boyfriend so...... well, he didn't torture himself with fantasies, but at the same time Chi-chan had a flirty, cockteasing way.

"Help me study, Kou-chiii~n. Take care of me and I'll take care of your chiiiiiin~"

## Characters
### Muroto Kouta (室戸 浩太)

One day he meets [url=https://vndb.org/c51006]Shiina Chieri[/url], a classmate of his, in front of a convenience store. After helping her with her studies, he is then offered sexual favors as a way to thank him for his tutoring, but only on the condition that they don't have penetrative sex. He is immediately captivated by Chii-chan's revealing clothes, voluptuous body, cute face and promiscuous behavior, all of which only make him want to lose his virginity with her even more.

Despite knowing that Chii-chan has a boyfriend, he still develops feelings for her beyond mere sexual attraction. This results in him developing deep jealousy of Chii-chan's boyfriend, as well as suffering in fear of his feelings never being reciprocated.

### Shiina Chieri (椎名 ちえり)
Chii-chan is a classmate of [url=https://vndb.org/c57763]Kouta[/url]. She is first seen waiting for him on a summer day in front of a convenience store. She asks him for help with her studies, seeing as her terrible grades could be an issue for her in the future. Kouta agrees to help her, which leads to Chii-chan offering sexual favors in exchange for his tutoring.

Because she has a boyfriend, she doesn't allow Kouta to have penetrative sex with her, believing that it's not cheating as long as it's not "real sex."

[spoiler]She has a lot of sexual experience with countless different partners. She has even prostituted herself at a very young age, believing that to be a way of getting back at her father. Despite her amount of sexual experience, however, she is still weak to sweet and heartfelt compliments from Kouta, such as when he calls her cute or praises her academic improvements.

It is implied that her current boyfriend is her first one. The boyfriend in question is Mr. Kubo, her homeroom teacher who is also a married man with children. They have a very distant and unhealthy relationship. Chii-chan often gets stood up by Kubo on important dates, such as the summer festival and Christmas Eve. The state of their relationship has been deteriorating for a while, which culminates into a breakup after Chii-chan realizes that she's always been just a convenient fuck buddy to Mr. Kubo.[/spoiler]
