"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~"

One day near the end of summer vacation, Kouta runs into his classmate Chieri near his home, where he lives alone. He was waiting here because he wanted to learn from Kouta, an honor student. Kouta agrees and teaches her how to study, and she offers to do something naughty with him in return, albeit with no actual intercourse since she has a boyfriend. Kouta becomes more and more attracted to Chieri's surprisingly honest and dedicated personality, who says that she will take care of his dick instead of studying...
