(With obscene muscles... Fallen into pleasure!? Me!?)
When Akane returns home, Okada-kun, a Tsugaru dialect university student next door who forgot the key, is always waiting for Akane.
It all started by chance, and at first I felt sorry for him and let him stay, but he gradually began to stay more often, and Okada's demands escalated!

"You like my muscles, don't you?"
Faced with beautiful sculpture-level muscles, I still wanted to endure them with adult reason... (past tense).
Okada-kun, who thought that he was like a younger brother, declared that he wanted to have sex seriously, even though he was overcapacity with just mountain-class muscles!?

"So cute, you fell so easily."
He's selfish, cute, but he's more erotic than anyone else... It seems that Okada-kun has a "secret"...?
