You gulp it all up.

“Aren’t demons evil?” You ask, a thread of saliva connecting your bottom lip to her engorged member.

She smiles, dressed as a latex nun she seems almost angelic, “Don’t be silly. Do you feel evil?”

“No. Well maybe.” You answer in a whisper then plunge her cock into the depths of your body once more. Savoring the delectable taste of it.

“Oh god yes.” She howls and clutches the back of your head. Her spunk rises up the shaft. You can feel it in your throat. It splashes a first spray directly into your stomach. The glue holding the wig on melts away and you feel the strands of fake hair fall over your shoulders. Another blast. The latex encasing you hardens and begins to crack.

“Mistress.” You hear a new higher pitched voice flow from your new mouth. Your tongue flits about in your mouth. Perfect teeth, a tongue stud. “Who am I?” You ask her. You remember being a human. You are pretty sure that is right, but you also know you are hers somehow.

“I will have to cast a spell to find your true name. I’ll do it later. I need to rest. There is a mirror in the bedroom, go play, see if you can figure out what powers you have.” She points to a hallway and closes her eyes. Suddenly another thought pops in your head, an evil one. You can see energy in her. Energy you think you could feed on. You shake the thought away. No she is your mistress. You look down the hall. A mirror. Powers. Hmm…
