this seems more like swingers to me, and thats ok in my book
( i guess Japan doesn't have a term for that?)
the only thing that bugs me is ,  the  artist seems to want to do hentai, im not much a fan of this half-and-half-almost-but-not-really-hentai  type stuff
for me its better when its all or nothing
Note~his actual hentai is tamer than this  loool, i like your stuff but, make up your mind dude
