This chapter reminded me why I dislike harems so much. This derogatory attitude and "hierarchy" are really messed up. Sure, it looks sexy, but at the same time kind of disgusting. It was Sherry's first time experience, and it was completely ruined by some random talk about order. Yet she still looked so happy about getting attention from her "owner". This guy came from the modern world, but his morality is completely messed up. It's one thing to buy slaves, as long as you don't treat them like actual slaves, and it's completely different when you actually treat them like some kind of pets. This kind of plot is fine for hentai, if it's only made for the purpose of fapping to it, but this tries to be a real manga, yet it treats female characters like brainless bitches in heat.
