dragon pink ruined me when i was a youngun, now i can only get off to stuff that have santa and pink dynamic. Well not really but it is an ideal, a rare one too. Master-slave stuff is either the case where they're in essence just a gf, or its all about sex and rape and there's nothing else to the relationship. Or they're completely submissive, which devalues the master slave power dynamic. The essence of a slave is them being property and having free labor and having no veto rights. What's the point if they're not treated like property and aren't used for free labor?
Mainly, there should be at least a bit of callous regard towards the slave, I like how he is willing to use her as bait, or to set off traps or as collateral or whatever.
I fapped to the scene of Pink pulling the wagon a lot back then...
and yeah i know its copied from rance, but I knew dragon pink first so
I like Itoyoko a lot in general, alice in slaveland, and slave girls were another couple old time favorites.
I read some time ago that Itoyoko was a woman too. Not sure if true.
see it says so on mangaupdates too
