@AMetroid I'm afraid I have to whole-heartedly disagree with you about Slave Harem's relationships. The MC of that story does not treat his girls as people so much as he does like valuable "tools" and "toys". All of his emotions towards them (the care he shows in maintaining their health and appearance, the jealousy he feels towards other men lusting after them, etc) is merely the feeling of a individual towards a cherished possession rather than a person (comrade, friend, family, whatever). Everything he does with them and for them is somehow based in his own selfish desires, and no matter how much care he takes with them, I have no doubt that he would abandon them in a heartbeat if his life was truly in danger. He may ask their advice, but he doesn't truly consider their feelings. I mean, sure... the girls he buys agree to the sex clause in their slave contracts, so eventual sexual activity is probably a given. But he doesn't even have the consideration to wait a little while for them to get used to him before he jumps on them. He has sex with Roxy little more than an hour after he gets her (if I remember right), and took the dwarf girl's virginity the night he bought her as well. It's ridiculous.
Now, don't get me wrong, I'm not against or trying to say there's something wrong with treating a slave like a slave (especially in a world where slavery is so widely accepted as to be common sense). But trying to wrap it up in some sort of way when it clearly isn't that way is stupid. Additionally, his slave girls are way too happy and accepting of his behavior just because he takes somewhat better care of them than a slave is normally, without realizing that he still treats them as objects and possessions rather than people. I probably sound like a hypocrite, but just... the attitudes of everyone in that story rubbed me the wrong way.
