Synopsis:

Kanata Tanaka, an introvert, got trapped in the gym storage room with the classmate he admires, the mature-looking Mio Yamamoto and managed to gradually work his way into having sex with her.
"That's enough for today! We can have sex on other days, okay...?"
With that kind of promise at the end, the two of them left the now-unlocked gym storage room.

Several days later, their awkward relationship continued and they couldn't even manage to talk to each other. One Sunday, Kanata gathers his courage and using the class contact info sheet, he makes a telephone call to Mio's house; He learns that actually, after all this time Mio also wanted to talk to him. Furthermore, because she is watching over the house, she's home alone! Just like that he gets swept into hanging out with her...

Mio in her private time is seemingly mature, but somehow also innocent, and she opens up her heart to him. It seems she likes manga and music, and surprisingly, it's all things that Kanata likes as well. They were born and raised differently, but they're on the exact same wavelength regarding hobbies, so much that he wants to be with her forever.

In Mio's room, while her scent, warmth and heart touches him, they become one.

3 creampies without pulling out! The curtain rises on sex full of understanding, and they become connected by a deep bond!
