The action is seen through the male character's point of view.
So your girl friend wins a trip to the hot springs.
And while doing certain activities there (e.g. table tennis) once in a while you’ll get horny and you ask her to satisfy you.
It’s not that great of a hentai in my opinion, I found it boring. But I’m not saying it wasn’t good, it was simple, some hentai are too complicated some times.
Well for one the girl never stops talking, it’s just
“yap yap yap”
*She complains about you staring at her*
“no I don’t want to”
“ok I will just this once” We know
So 5/10 is my score.
