Everything has a price

"Because, Mistress, you made me yours by making me climax and letting me give you pleasure. You are my lover, and I am your ****.", Tiffany replies. You're a little shocked by how she is so matter of fact about it.

'Oh, I should have mentioned that, shouldn't I? Anyone that you have sex with will be yours for a limited amount of time, relative to how many times they cum and if they make you cum. It's only temporary with each person, but the more people you make yours, the stronger and longer the connection is.', the spirit explains.

'What? So, how strong is this connection, and what can I get people to do?', you ask in your mind.

'That depends on how much of a relationship you had with the person before. For example, if you fucked a random guy on campus, it might last a couple of days, and you could get him to do simple things for you. If, say, you are kinky enough to be into **** and fucked your father, it would be months and, well, I think that the best way to put it is he would take a bullet for you. Since Tiffany isn't family, but you are friends, she'll do anything that doesn't involve actually enduring physical harm and she should be good until Christmas.', the lust spirit explains.

You know that you should be shocked by the fact that the necklace mentioned **** and that now you can control people, but the pleasure of having sex with your roommate and the energy that you're feeding off of from the orgasms is warping your worldview a little bit. Still, there is time to get back to normal, because what would you do with so much power? You can take the necklace off and go back to being you, right?
