Not if she has any say! But... does she?

(Stacy's Pov)

I was dreaming right? I had to be dreaming. First, Chrissy, the most beautiful woman in the world knocks on my door in the middle of spring break, cooks me dinner, takes a picture of us cooking and then eats me out. That, this can't be real. Now she is saying this could be forever? What could I say but well.

"Okay," I said looking at her. She was holding an odd book. It looked like entomology? It had a pinned moth on it with a purple cover. It had, runes? The purple color made it look like something from an anime. I got a bit of an evil sense from it. But, well, for Chrissy. Anything. I would do anything.

She smiled, and my heart melted. "It may sound a bit strange but this thing can be a bit intense even with touch. It gave me a real challenge yesterday. Mind if I tie you up? That way, you can't escape us?"

I smiled. "Okay."

For anyone else, that probably would have bee a red flag, but why should I care? This was Chrissy. She was soooo gorgeous! So amazing! I closed my eyes and could just feel her tying my arms to my own bed post. "Your not gonna leave me right?" I asked.

She smiled. "Never. I want you, silly."

What was she, oh, she's using pillowcases to tie me up. I could feel them tightening around my ankles next, right against my bedposts. I bit my lip. I just came a few minutes again but thinking of having kinky sex with Chrissy was already making me beyond horny. With my eyes closed, I could hear the desk chair wheels coming over.

"Ready?" she asked.

I nodded.

I felt something heavy touching my stomach and... what? Suddenly my entire stomach was on fire. "Ugh! That's soooo. Hmmmm. What is that?"

Opening my eyes, I noticed she had put the strange book on me. I let out a slight moan. Wait. But, how?

She just smiled. "Yesterday, you thought I was having sex with Eddie, but I wasn't. This is what was happening. I was begging you for help. And you didn't come-"

Wait what? I re-

She pressed her finger to my lips. "Don't worry, this isn't revenge. I'm not mad. I am so happy. This is me returning the favor. I wouldn't do this for just anyone. So, enjoy it. Feel what I felt. Become a sister with me."

"I-"

My back arched and I moaned. My pussy was on fire. It was hard to breath or talk like this.

She leaned in close and kissed my cheek. "It is so fucking hot, watching my Lord work on you. I wonder how long you will last. He said I lasted almost three hours. Don't worry. I won't leave you alone. But don't scream, I don't want anyone interrupting us."

Hmm. The heat was... subtle but constant. Hmm, it was... like a subtle but constant throb. I could feel a kind of hunger underneath it. She occasionally came over and licked me when she noticed I was about to cum. Fuuuck. Hard to think. Was this magic? She stared at the book and occasionally nodded to it. When she did she began taking aware cues. Like taking the clock off the wall. Putting a blanket over the window.

Everything she did just made it harder and harder for me to understand how much time was passing. It was like it wanted me to feel a distorted flow of time. Ooooof fuuuck, her tongue.... so soft. "I love you." I whimpered.

Don't you want relief?

Huh? Was... the book talking to me? Interesting. No. I can take it. I wanted a full night of being fucked by Chrissy, so the jokes on you.

"Hmm? Yes my Lord. Stacy, I can no longer touch you until either you or my Lord has given up," she said.

"Huh? Your lord? What... MMMhhhhmnnng," that sudden just of arousal felt good.

"Yes. Oh, right. How to explain it," Chrissy said, rubbing her chin. "A mortal can't hear Him. Not directly, but since your touching his Him. He can't infuse a few of His words in your mind. You'd probably recognize it as thoughts you didn't think?"

Fuuuck. Fuuuck. I'm cumming, even without her licking me. I was nearly panting afterwards. "Wait. Touching me.... but," I paused to breath. "The book?" I asked.

She nodded. "Please show Him respect. I can handle neutral even if I don't prefer it. But disrespect Him and I will hate you."

Hmmmmm. What did that... no wait, it could speak to Chrissy. Book, you know humans have.... fuck, that feels so good. Humans struggle with intrusive thoughts! Okay, so you did something to her. Mmmmhnnn.

"Ha... aaaah....., explain. What happens.... context... pleaa-"

My entire body tightened. God damn! Fucking fuuuck fuck me.

"Can I? Yes my Lord. Well, if you give in. You become, like me. Hence me saying sisters," she said. "If you resist, a few things could happen apparently. But I mean, my Lord losing just sounds like coup to me."

I didn't know what to think. I mean, this felt like a demon obviously but was there any truth to this? Was it some crossroad demon with there some can't lie aspect? Maybe it was just gaslighting me? Hmmm. Fuck. Bursts of arousal to disrupt my thoughts. Chrissy charged her phone, but she walked around. She unplugged her phone as well. Was that? A measurement of time? No, I can't relay on that.

For all I knew, this book had a time limit I was close too, or it had unlimited time and it was just trying to get me into a state where I would bargain.

Everyone desires. Bargain, eventually.

Yeah, well. To that I say. Do you like math? Three point one four one five nine two six five three five eight nine seven nine three two three eight four six.....

Thirsty. Hungry. Sweaty. The bed was soaked. How much fluid mass had I lost? I needed fluids soon.

"Oh, shoot. Lord. Eddie is texting me. Should I ignore him? I did say I would stay with her the entire time," Chrissy said.

Chrissy leaving, unless you accept relief.

Fine then. "Wait a second though, before you go. I need water."

She smiled. She adjusted the book slightly and her smile faded. "Lord, but... oh. I see, the mark won't appear until she consents. Gotcha," she turned to me. "Wanting to eat, to drink. Such... good things. They will help you give in. My Lord said no. You are stubborn."

"..."

Wait... was that a static buzz? I... no that doesn't matter. "But, I could die," I shouted. "This game isn't fair if I could-"

"It isn't a game," she said. "I would hate for you to die. I really did enjoy my time with you. My Lord would never let you die, but you have to consent to him. You already beat my record. Lord, may I- Thank you."

She leaned in close and kissed me. "I'll be back. If you do give in. Come next store. We can suck Eddie's cock together. I would love to share your first cock with my new sister."

With that, the door clicked shut. Ugh! I... Urgh! No no no no! I didn't want to suck anyone's cock! Not even for Chrissy! Hmmmmhhnnnngggg stupid boook. Giving me an orgasm while I was thinking about something so gross. Okay! Fine! Let's lock in! If I lose, your gonna like make me a slave right?

Not exactly.

If I win, I get to leave?

Maybe.

Lets raise the stakes!

You propose what?

If I become a demon, do whatever you want to me! But! If I win! I want you to free Chrissy.

Hmm? Was he too scared? He wasn't answering. That was for sure.

Cannot undo change to Chrissy, but can modify, acceptable?

Yes! Bring it on!

Suddenly my entire body went tense. My eyes were crossing and I couldn't breath. This orgasm was like fifteen times stronger than anything before. It wasn't stopping either. Ugh! No. Not going to.... lose that.... easily! Three point one four one five nine two six five three five eight nine seven nine three...
