Enslavement

"What's wrong, human?" Demona asked, with a smirk on her face.

Before you could answer, you felt a bit different, like you should listen to Demona.

"What.... What did you do to me?" you ask.

"Just a simple spell. I can see that you would make a worthwhile servant, so I used a special spell on you." Demona said, as she continued to use her tail to stroke your dick. "Every time you cum, you are further enslaved to me."

After hearing that, you put more effort into trying to escape her grip. Too bad she places her breasts in your face.

"Why don't you suckle from my breasts? You might get some milk?" Demona taunted.
