Manga-wise, Maou no Hajimekata is one I like and pretty close to what you want. Some asterisks.
The main character, unapologetically awful (ex)-human being, well, he uses whatever he can get his hands on. But his stated motives are eternal youth, power, wealth and women(in actuality, those are only about 90% of his motives, but spoilers!). He is very happy to brainwash, dominate or bind through magical contract the women he wants. If the eternal youth, power and/or wealth do not do the trick.
He has a main harem of about 6 people(debatable). Of those, all of them are bound by contract, two of them are bound by Several, one is hypnotized to love him, one is brainwashed into a double agent, one was trained into a sex addict until she gave up her soul for the D... This manga is a lot of things, but it is not subtle.
When he does not do that, he still manipulates and corrupts the hell out of them, and everyone else besides, which I find has a similar appeal. Sometimes he Could mind control people in an instant, but chooses to fuck with them normally just to flex the muscles.
