Doesn't seem like he's got much of a choice.

"Okay. I'll do what you want. Just please... stop."

Kinzie's smile was bigger than the Cheshire Cat's. She pulled out of my mom, and pointed her dick to the left. Thick ropes of sticky cum shot out of her cock, coating the walls of the living room. The semen was smoking lightly, smelling like sulfur, before evaporating, leaving no trace. My mom and my sister both got a foggy look in their eyes, before passing out where they lied.

Kinzie walked over to me, and kissed me on my cheek, or rather, she kissed a forcefield appearing in front of my cheek.

She looked amused.

"Time to get rid of that!" She sang.

She grabbed my arm, and dragged me up to my room. I looked behind, and saw my mom sleeping, naked on the dinner table, and my sister slumped over a tableleg.

"What about them?" I asked with concern.

Kinzie didn't even look back, but continued dragging me up the stairs, into my room.

"Don't worry about them," she said, kicking my door open. "They'll wake up in an hour or so, dazed for half an hour, where they'll put some clothes on, and cook dinner, without any memory of what just happened."

"Really?" I asked, skeptically.

"Hey man, if this relationship is going to work, you gotta learn to trust me!"

"You just **** my family!"

"Oh shut up, you big baby, and let's get down to business!"

She did some weird hand-movements and a large flame erupted from my floor. I yelped, and leapt back, while Kinzie looked wholly undisturbed.

A long piece of paper materialized from the flames, and Kinzie took a pen from my desk and handed it to me.

"So if you'll just sign here..."

"Ohh no. No way." I said, crossing my arms in defiance.

"Ugh, what now?" Asked Kinzie, flapping her wings impatiently.

"Do you think I've never seen a contract in a demon movie?" I said, knowingly.

"Never, ever, EVER sign a contract from hell. Aside from the contract probably making me sign with my own blood, there's probably some teeny tiny atom-sized text saying how I'll accept you pegging me with a cactus or something like that."

"You... you have issues." Kinzie said, with a disgusted look on her face.

"No contracts." I said, sternly.

"Fiiiine!" Moaned Kinzie, and waved her hand. The contract disintegrated into dust.

"Then just repeat after me:" Kinzie said.

"I, (your name here)"

I repeated what she said. She raised an eyebrow upon hearing my name.

"Really? That's your name?"

I shrugged.

"Oh well. Ahem! I will now repeal the Angelic Presence within me, but only when it comes to sexual favors from the Succubus by the name of Kinzie!"

I repeated what she said. "But no physical harm, right?"

She smiled. "Only sexual favors, man. But if you're feeling curious one day, we can always re-negotiate the terms..."

I felt a shiver down my spine.

Kinzie continued.

"Kinzie will be allowed to do whatever she wants to me, on every hour of every day, no matter what I happen to be doing at the time."

I repeated. "But no pegging. Or nasty stuff."

"I won't get cum from that, dummy!" She laughed heartily.

"This repeal will be in order from now, to the end of time." She continued. "I am aware that this will be permanent, without any takebacks. I accept whatever consequences this will bring."

"...will bring. Ok, what happens neWHOA!"

As soon as I had repeated Kinzie's sentence, she had picked me up with inhuman strength, and threw me down on my bed. I tried sitting up, but in the next second she was on top of me, forcing me down by by inserting her tongue into my mouth. I stared up at her soulless eyes, her wings spreaded out, drowning out the light from my lamp in eternal darkness. I felt her tongue, which was most definitely longer than any human's, explore every nook and cranny in my mouth, before sliding deep into my throat. I felt myself being choked, and I stared terrified into her merciless black eyes, void of any hope.

Just when black spots started inching their way into my vision, and I began losing consciousness, her tongue retracted, and slithered back into her own mouth again.

"Now," she panted, smiling maliciously, while I coughed wildly. "You get the night of your fucking life!"
