Adult PC Game: Silly Girls Quest v1.20 by IZAKAYA YOTTYANN Archive

An erotic RPG where you have sex and go on adventures with your sexually active friends.
H scenes are released by exploration elements.
The world view is connected to the previous work Obasans Saga, but
I don’t think there is a big problem even if you haven’t played it.
(It may be easier to grasp the world view if you have already played.)​
