Hina, a third year university student, was worried.
She can't sleep...
She's job hunting, internships, and vague anxiety about the future...
While she is spending her sleep-deprived days, Tani-senpai, a popular student in the same seminar, approaches her with a proposal.

“Isn’t it bad to sleep alone?Aren’t you saying you can sleep better when you have human skin?”

The two of them end up sleeping together in the senior's bed at his house.
Although they were skeptical, the effect is tremendous --!?

In this way, Hina became a co-sleeping friend = "Sofure" with Tani-senpai.
One night, several months later, by chance, Hina ends up clit-masturbating with the fingers of her sleeping senior.
Just when she was finally about to reach her climax -...

"You're a bad boy."

Here, just say, I used my senior's fingers without permission to masturbate.'
' ``If you say it properly, I'll forgive you.''

Just like that, her clitoris and portio were being fucked, and she was drowned in too strong pleasure...

After that, Hina's relationship with Tani-senpai became more than just a "souffle".
However, due to some circumstances, she will not be able to meet her senior for a while...

At first, Hina thought she was fine, but
there was no way she would be able to sleep alone, having learned the taste of being put to bed by having sex with her senior...

(I...I don't have a senior anymore...)

After reuniting with her senior, Hina is at the limit of her patience...

"Really, Hina-chan is no good without me."

"It's my fault that I was able to discipline you like that."

This is a story about a kind and gentle senior who speaks the Kansai dialect who teaches a lot of pleasant things to her body,
makes her cum a lot while teasing her, and puts her to bed.
