@HYBRID_BEING kinda surprised about that too. After "Goblin Slayer" there isn't really that is so "rape-y" except most of the revenge stories. "Revenge Healer Hero" dude was even a sad case of everyone with power "force humping" weaker people.
Some stories have the subtlety of saying turning captives into bed slave but need some training first or the bluntness of near shmentai with full view nipple shots, grunting, screaming and or moaning with drugs here and there.
Its all about the skill of the author and the style of the artist in making it a fit for the story, unnecessary or a total turn off. Just my opinion.
Hey gotta have some chubby ladies for some of the fans that might light that, she ain't so bad.
