Succubus: Taken by my Boyfriend's Present (Futanari Succubus Erotica)

Sandra has kept her succubus blood a secret from everyone. It’s never been a problem, until her boyfriend binds a powerful futanari demoness named Azel, and sends her home as a bodyguard for Sandra. Her boyfriend has no idea about Sandra’s succubus blood, or the fact that Sandra won’t be able to control or subdue the demoness Azel. Sandra will be powerless to the demoness’s naughty intentions for her, as her succubus blood is gradually awoken.

Excerpt:
"
I lifted a brow at her. “And what sort of demoness are you?”
“The kind that’s good at getting what she wants,” she said.
I turned my head and looked across the room, towards the storage closet. “Is that why you went and got yourself bound to a human? I doubt that’s what you had in mind when you started the day,” I told her.
“Everything works out in the end,” she said. “After all, now I’m here with a lovely little succubus. I haven’t been around one of your kind in a number of years. Tell me, when was the last time you serviced a demon, as your kind is compelled to do?”
I listened to her question, but didn’t immediately respond. My heart rate had increased the entire time she’s been here. It was as if something was in the air...or perhaps her presence was riling me up.
