Deal with the devil

Katarina sat up and stared hard at the imp now. His cock had shrunk somewhat, going slightly flaccid after that magnificent cumshot. She licked her lips. Maybe there will be more where that came from.

"Imp, I'm going to need you to come with me to stop the others. You said you would help right?" The imp looked at her quizzically, considering her for a moment. She felt his eyes scan her body up and down and he started to mutter under his breath. She heard a few choice words like 'betray' 'beautiful' 'chance' and 'run'.

Impatient and ridiculously horny Katarina got up from the ground and grabbed the imps cock squeezing hard. "Well?"

"Ahhhhhh yes, mistress. Imp help you! But brother cannot find out I betray them. They will kill me you see. Or tell Lord Xandius. That would not be good. Not good." his cock was growing hard again, almost fully erect.

"Fine, I'll make sure nobody finds out. I can't let anyone else know anyway."

"I get to fuck you. Five times a day."

"Absolutely not, you already told me what happens if you cum inside me. And FIVE?"

Can he really go five times a day? Stars, could she?

"I pull out? Four."

"I can't possible trust you with that. I'll use my hands or feet. Three."

"Once in mouth, then you can use whatever for other two. But I get to choose when."

"That sounds incredibly convenient for you. I'll choose when," Katarina was getting impatient, she was stroking the imps cock, not really paying any attention but enjoying the feeling of it in her hands.

"No, I get to choose, but I promise not to request it when not appropriate."

"Fine. Wait! When did you start being able to speak normally?"

"Oh, that pink spell you cast at me wore off when I came. I am the smartest of my brothers actually and my jaw is healed too."

He snapped his fingers and a piece of parchment appeared with red ink scrawled all over it. He handed it to her and she took it in her left hand, her right still stroking the demon.

"Read it thoroughly, there's no going back."
