Tonari no Ano Ko wa Kikoku Chijo

The girl who moved in next door was a year younger than me and had spent a long time living overseas.
Her name was Yuumi.
For some reason, her name felt familiar, but I was sure I didn’t know anyone as cute as her.
Yuumi had a clear, serious vibe, but her curvy figure was obvious even through her clothes.
Her parents asked me to look after her since we went to the same school, and Yuumi herself asked me to help her with her studies. I agreed.

Yuumi came over to my place to study.
But while we were going over her work, she kept leaning forward, giving me a clear view of her chest.
Trying to stay calm, I excused myself and went back to my room… only to find Yuumi pleasuring herself!?
And to my shock, she reached out and grabbed me down there!
Turns out, Yuumi—despite her innocent appearance—was actually a bold, naughty girl who was very into this kind of thing!!
