Harem Gathering

Whatever kind of power you have, has certain a guideline to be able to gain your harem:

For this power to work, you have to cum in whatever girl you are trying to get. Either mouth, pussy or ass. However, each hole has a different effect: the mouth makes them more submissive before you claim them, the ass makes them hornier around you, and the pussy is what turns them into your loving .

For example: say you've gotten a girl to date and do other things, but not go all the way. The more times you cum in her mouth, the more willing she'll be if you demand to fuck her pussy. The more times you cum in her ass, the hornier she'll be around you and she'll be the one who wants you to fuck her pussy, however the ass takes time, she won't feel the effects until later that day, after you've gone about your daily business. When you cum in her pussy, the effects of cumming in her ass and mouth will vanish, as she becomes your obedient harem .

And that's it. You are your own OC with whatever extra powers you want.
