Probably my most wanted concept of all. If you're interested to play a bunch of girls against my harem protagonist, I will be overjoyed, please contact me so we can work this out. As harem scenarios always result in imbalanced workloads, I'd be happy to play some of the female characters at times.

Enthralled series by Prax Venter - an incredibly niche piece of erotica

Don't worry if you haven't read it. I'm open to deviating pretty far from the source material anyways.
Essentially, the pitch goes that the male character is in a fantasy world where he can 'enthrall' and take several women as his companions. They fight alongside him, and he has magical powers that boost their abilities.
When they've completed quests and defeated monsters, the acquired experience goes to MC, and he has to transfer it to the women through sex acts before they can spend their acquired experience points.
I can see the overarching story going in a lot of different directions, so I'll end it here!
