Plot:
Main Character is kidnapped by 5 women and tortured by them...and that's it. Some chapters are just him being tortured.
And we need to talk about the tortures...well, they are highly sexual.
This manga include: cross-dressing, shaving, cunnilingus, anilingus, fisting, pissing (golden shower and drinking), diaper fetish, dog role-play, baby&mom role-play, shota, rape, lesbian rape, etc...I think the only thing I didn't see was scat, but a character was threating to shit in the MC's plate if he don't eat his food, so that's that.
Anyway this manga is a masochist dream.
The story truly have a mystery which is why they are torturing him, but well, we still don't know and showing the sexual tortures take precedence.

Art:
As you probably noticed the manga is a borderline hentai. Expect a lot panties shots, ahegao, girls are naked most of the time and having big boobs.

Characters:
Nothing much to talk about them without spoilers, but to summarize all the girls are very crazy. In fact, all women in this manga are crazy and weird sex maniacs.
It's difficult to judge MC...He do nothing to try to escape most of the time and It's not even enough time to Stockholm to kick in.

Enjoyment: Meh, just reading because I'm curious about why they kidnapped him.

Overall: If you are a masochist, read. You probably will like.
