Ganki Tengoku

One night, an unskilled salaryman meets up for a date with a cute young girl. They talk, and just that way he becomes happy. They meet again at a combini. She has a part-time job there.

From there the relationship takes flight, the two of them playing together, meeting together, and being together...
Who knew his life could be this great... as soon as he finishes work he's mailing her, meeting her every single day...

And then there's a sexual electricity between them. And she says to him with a new, aroused gleam, her face beet-red with embarrassment...

"Can I sit on your face?"

Teenage Yuzuko and (you!) in sexual sixty-nine heaven.
