The Change

"You're not supposed to be able to touch me."

"Let me guess, the translation again." Her hand passed through my sister again and again Jess screamed as she was lifted up. "As you can see, I can do whatever I want. For example, what I'm doing right now is slightly squeezing your soul. Would you like to feel what it feels like when I close my fist?"

"No! Please, God, stop! I'll obey! I'll obey!"

"Willingly obey?"

"Yes, I'll willingly obey you."

The demon smiled and glanced at me, "And him."

"What?"

"He's my vessel on Earth. Does me no good to have you willingly obey me if I'm in Hell or on the other side of the planet doing my job now does it? How am I going to feed if you're so far away?"

"But, I thought this was a one-time thing?"

"You aren't asking for a one-time thing like a bunch of money or anything like that, you're asking to be famous. So, as long as you're getting what you want, I get fed."

"That would mean, you're giving him control over me for the rest of my life."

"No, pumpkin, you're willing to submit to him for the rest of my life, and it's not even that. It's more like when he whips his dick out, you satisfy him in any way he wants. Maybe it's once, maybe it's a million times. Doesn't matter."

"You know what I want, how will I be able if I'm his slave?"

"I'll take care of that part, don't worry, I always keep up on my side of things, but only if you never refuse him. Do you understand what I'm telling you? You can choose to refuse him, but if you do then..." Her hand disappeared into Jess's body and my sister screamed. Jess said she understood and was released. "Good, then COMPLETE THE GODDAMN RITUAL!!"

My sister, the woman who once thought she was smart enough to outsmart a demon meekly fell to her knees and crawled toward her burnt brother. I could see in her eyes the slow realization that the only choice left to her was to serve the overweight loser of a brother she was so eager to sacrifice only moments ago. To become who she wanted to be, she would have to become my willing slave or suffer the torments of Hell.

"Wait, this isn't right," the demon called out as she reached out to touch me.

"Oh, thank God," Jess said in relief.

The demon snorted, "Let's not thank Him just yet, shall we?" The demon stepped close to me and whispered, "I don't have time for you to finish in a timely manner and since I can't have a fat man with a micro-dick out in the world representing me I'm going to speed this along. Sorry, but this is going to hurt, a lot."

She pressed her palm to my head and pain exploded through my body. My screams ripped through the forest causing Jess to jump up and step away from me even as I felt the demon reshape my body. By the time she was done, I was taller than Jess and was rippling with muscles. My hair was thick and long with a matching beard to go with it.

"There's that's better," she said as she pulled my face from side to side. "Now this is a cock I'd proudly call one of mine," she said as her hand slid around my manhood.

My head was free from whatever my sister did to me, I looked down and was able to see that my small Tootsie Roll had disappeared and in his place, there was a long thick slug hanging from my body. I wasn't sure how long I had become, but I was bigger and rounder limp than I'd ever been hard my entire life.

The demon smirked as she stroked me. I grew hard at her fondling. "Mmm, I may come back and use this beauty myself." She turned to Jess, "Okay, we're good to go, time to hop on pop."

"No. This isn't right or fair. You can't take my soul just because I won't fuck my brother."

The demon shook her head and laughed, "I like you, you're stupid. If it makes you feel better, he wants it."

"You're lying. No one wants to fuck their sibling."

She walked around me and I could feel her hand touching places only my doctor had touched in a very long time. "Lying? Little girl, this cock isn't hard for me, if it wasn't for me he would've already buried his bone in you. Granted, he's little more than a beast right now, but believe me when I tell you all he can think about is fucking you like an animal in heat right now." She shuddered and hefted my balls. "Damn, come feel the weight of these things. This is forty years of taking shit from everyone, including you."

The more she talked the more I could feel the overwhelming urge to take my sister whether she wanted it or not. I tried to push it back down, but it was like a living thing boiling me from the inside.

The demon looked at me and smiled. "Don't fight it, baby. Trust me, it'll feel so much better if you give in." She turned back to Jess and said, "It doesn't really matter if he gives in or not, at least not mentally because regardless of what he wants, he's too weak-willed to stop my desire. That's good because I have plans for him. His life will become a testament to the Dark Lord of Wants and Desires." She touched me and I jerked a little. "Ooo, he's fighting so hard and you know what? He might actually succeed, at least for a little bit, but the more you tempt him with your sex, the less he'll be able to resist. The more he experiences you, the more he will feed me."

"But what if he finds a way to resist me? Like permanently? What'll happen to me?"

"Then you'll become a bigger failure than you are now, but don't worry, he might be able to resist for a bit, but with you offering him the very thing his body craves, he'll eventually give in. And besides, I have faith in you. Faith that what you want is bigger than what he wants because unless you accept his orgasm, my essence, into your body regularly, then my little deal maker, our bargain will begin to crumble."

"He's too big for me." Both I and the demon knew it was her last-ditch effort to prevent what was inevitable.

The demon laughed, "He's eight inches and he's thick enough to stretch the pussy of every woman on the planet. Not those size queens of course, but even they wouldn't turn him down. He's perfect and we both know you've taken bigger." She smiled as she aimed my hardness directly at Jess, "Your fans calling out for your greatness so go ahead, feed me, and rocket into stardom."

Jess glanced at the demon before looking back at my groin. I could see her weighing her options to either damn her brother or suffer the slow destruction of her own soul. Her demeanor changed when her decision was made. My heart sank even as my excitement rose as she dropped back to her knees and lean forward. Her nose nestle into my crotch and I heard her take a deep breath breathing in my scent.

"Dammit, I love that smell. So masculine, so powerful," she mumbled causing the demon to smile.

The more she drew my smell into her body the more excited she became. She smiled as she began squeezing her breasts even as the other took me from the demon. Surprised, my eyes grew wider when she wrapped her fingers around me and found themselves lacking. Jess's hand slowly began stroking me and I could feel the demon's hunger ached for her. When she flattened her tongue and dragged it up from my heavy sack to the tip of my erect member I almost came.

"Oh God, Jess," I gasped as my voice returned.

She glanced up and smiled at me. "Don't worry, big brother, this is your lucky night. I might not be good at many things, but I'm damn good at this."

Her mouth opened as she locked her eyes onto mine and sucked my cock into her wet mouth. My tip quickly hit the back of her throat and I knew my neglected body would want to cum sooner rather than later. She pushed me past the point of no return when she grabbed my ass and guided me to fuck her face.

I growled and the demon smiled, "Yes, my vessel, take your sister."

The demon's hunger broke free from my control and took over my body. My fingers slid into Jess's hair and as she moaned, my blood began to boil. She palmed my balls and I began to thrust into her harder and deeper. Her hands grasped my hips and tried to slow me down as I used her mouth as I would her pussy, but I refused to stop. Her only hope to stop my onslaught of her throat was to make me cum. She was right in that I was almost too big for her mouth and throat, but even though I was filling her mouth, her tongue bathed me as she pushed me toward the edge. Tears and spit flowed down her face and my balls as I pushed myself deep into her throat and pulled her face to my stomach. I felt my sack tighten as my tip pulled all the way out to her lips then raced back into her until my balls rested on her chin.

She hadn't been lying when she said she was good at cock sucking. It didn't matter how hard I drove myself into her, she moaned in ecstasy as much as she gagged. It was those noises coupled with whatever her tongue was doing that created that old familiar tingle and within moments, I pushed deep into her and exploded directly into her stomach. Her eyes were squeezed shut but she didn't try to pull away from me. She just kept swallowing everything I gave her and it felt amazing on my shaft. As I relaxed, I released her finally allowing her to lean back until I fell from her lips. She wiped her face taking long deep breaths and I expected her to look at me with fear, but she didn't. She looked up at me, completely under my dominion and when as her breathing became calmer she leaned forward and began nursing on my cock. I reached down and stroked her hair and she hummed contently.

"Yes," the demon moaned as she licked her lips and hugged my muscular body. "God, that tastes so good," she said. "Mmm, do that often and you will be rewarded. Serve me well, my vessel, and you too will be generously rewarded."

The demon smiled as she vanished and left us in the middle of the forest, me standing naked over my equally naked sister as she stared wantonly up at me. As the cum left my body and my softening cock slipped from her mouth, my ability to clearly think again came rushing back to me. I pushed her back and looked around for my clothes.

"Holy shit, Jess," I said in a deep voice, "What the fuck is happening?"

Her voice was rougher than normal, a result of my vicious face fucking. "You were so demanding, so forceful."

"I don't know what came over me. I'm so sorry."

The grin she gave me was almost scary. "I don't want you to be sorry, I want you to do it again."

She grabbed at me, but I backed away. "Are you crazy?!"

"Jesus, Alex, I've never had anyone dominate me like that. You didn't care what I wanted, you just knew what you wanted and I was you're fuck toy. It's awakened something in me. Or more accurately, it's re-awakened something in me and I want more, baby."

She grabbed at my leg again but I caught her wrist and pulled her up. Another surprise, my new strength allowed me to easily lifted her to her feet. She took a deep breath and leaned into me her tongue slipping between my lips. For a moment, the lust returned and I gave in. I groped at her ass as I pressed myself against her nude body and had to fight from splitting her legs open to take her again.

I pushed her back, "Stop," I commanded. "Where are my clothes?"

"I don't know," she said as she looked around, "I think Brenda put them in her bag. She didn't want them to get dirty."

"Yeah, that makes sense. Kill me, but keep my clothes clean, fucking geniuses."

As I walked away, not knowing where I was going, she yelled, "Wait, Master." I looked around to see her holding out her robe. "I'm sorry I don't have anything better." Weirdly, she looked genuinely distressed at my disapproval, but she perked up when I wrapped the material around my waist, it wouldn't fit any other way. We found my shoes, but my change rendered them useless. I threw them and again seemingly upset that I was mad, Jess ran to pick them up. It was a strange sight, my sister who rarely did anything for me running and fetching like she was my pet. I began to wonder what my pet would do for me, but pulled my mind away from such thoughts and started walking again. Jess pointed without saying a word and I assumed she was pointing to the car. With every step I gritted my teeth against the sharp little objects I was forced to walk on, and with every wince, Jess asked if I was alright. I told her over and over again I was fine and to keep going, but after the hundredth time, I stopped.

"No, Jess, I'm not alright, okay? You gave me to a demon so you could have a good life. Not only that but my body was literally forced to change within minutes. Do you know how painful that was?! Yesterday, I had a sister who loved me and watched out for me, but today, I've got one who I hate and at the same time am forcing myself not to throw down and fuck."

She started pulling at her clothes, "If that's what you want, I'd be happy to please you, Master."

I watched as she disrobed and stood before me naked again. Damn her, I thought as my cock grew. I looked around and saw where a tree had fallen over and because my need was greater than my logic I pushed her across the log and stepped behind her. I ran my fingers across her warm opening and found her almost dripping with excitement. I didn't bother to tease her as I forced her waist into a position best suited for me and slammed my hardness deep within her tight cunt.

"Oh God, Alex, fucking split me in two! Fuck my pussy, brother, fuck me until you flood my womb with your hot cum!"

Her voice was still raw from earlier, but I didn't care, I just wanted to hear her scream my name again. I gripped her hips tight as I drove in and out of her little box. My sister might have been chubby, but her pussy was nice and small. If she hadn't been so wet, I was sure she would have stripped at least two layers of skin from my new cock. I enjoyed the power I had over her and as our bodies slammed together her ass jiggled a little and for some reason that made me hotter. Quicker than I thought possible, she was screaming and I could feel her inner walls get tighter. Holy shit, I'm making my sister cum on my dick. I was both disgusted with myself and reveling in her body.

My sister's body, in her younger days, was the desire of every man around her, but as time went on, her attitude and exercise routine changed allowing her to gain the extra weight. As I fucked her in the forest that night, her once large B-cup breasts had grown over the years to mid-sized Ds and her once taut stomach had turned grown. She wasn't large enough to have an overhang over her shaved pubic mound, but she was getting closer every day. She still kept up with her beauty routine and still chased the latest fashion so she still turned heads, but not as many as she did in college. Honestly, I think she could have found a good man and still had a good life without sacrificing me, but her anger pushed everyone away until she was left with no one. I almost felt sorry for her as I flooded her gushing twat, but I was still pissed about what she'd done to me.

I pulled out of her and said, "Clean me with your mouth."

I didn't ask, I demanded and as she complied I wondered where my new arrogance was coming from, but as I looked down and couldn't see a part of me that had been with me for over a decade, my huge gut, the demon flashed in my mind. Pushing it all out of my mind, I rested my hand on my sister's head and enjoyed feeling her movements as she licked me clean.

She finished and looked up at me with a smile on her face. "You taste so good, Master."

"Is that our new role now? Am I your Master and you are my slave? Is that part of what you agreed to?"

She looked at the ground and shrugged. "All I know is that I know what I did and I know how shitty it was, and I know what I have to do to keep it." She looked up at me and said, "Alex, I know I put up a good act, but it was what was expected." She laughed, but it was mixed with tears. "Wanna know what's fucked up? The only time I've ever felt good, like a deep down contentment with life is when I've been used sexually. You fucking my throat back there without regard for my comfort gave me such a sense of purpose. Bending me over and satisfying yourself with my body... even now I can feel my body glowing from the warmth of your hot cum."

"That's the most twisted thing I've ever heard. Especially from someone who's had a life like you've had."

She laughed and there was a little maniac quality to it. "You don't think I don't know that? I mean, I was never diddled by a pervy uncle or anything like that, but all my life I could feel something missing. Then I got into college and I started experimenting with my sexuality. The more I played the more I realized I wanted and needed someone to control my life, but none of the guys I know wanted to be my Master."

I petted her head and said, "Is that why you're life went to shit?"

She nodded. "I started feeling like my sexual needs were wrong, like my wanting what you've been giving me tonight was something I shouldn't be wanting so I just stopped. Stopped living, stopped taking care of myself, and started diving deeper into social media. I mean, I still want that life, but God, Alex, I want you so much more."

"And that's why you sacrifice me to a demon?" She nodded. "Are you even sorry?"

"I want to say yes, but... Well, look at you, Alex, you're a god now," she said as she ran her hands up my stomach to my chest and kissed my dick. "You heard the demon, you'll have a life most people could only dream of, and with me by your side..."

"With you by my side, what?"

"For one, you'll never have to worry about pussy, or blowjobs, or even anal. I'll give you whatever you want, I'll be whatever you want. You want a threesome? A foursome? Hell, you want me to help you pack a room full of women all begging to be dominated by you? I'll start scouring the countryside."

I sighed and held my hand out to help her up. She went around my neck kissing me. I hesitated for a moment then gave in. She must have sensed my acceptance because her body melted into me. The fire in my groin began to grow again and even though I would've been happy to bury myself in her again, I knew I needed time to think. She dressed and led us to the car. While she drove us home, I leaned the seat back and dreamed.

I was standing on a balcony under a blanket of stars. The sky was clear and I felt as if I were looking into eternity. I knew it was a dream because I could see moons, planets, solar systems, and galaxies moving over my head. When I looked around I discovered the platform I was standing on was attached to a large castle. It was made of some kind of reddish black stone which was held together by a vibrant blue mortar. All of it, the stars and the castle, blended together into a gorgeous tableau. At least until I looked over the edge. The balcony jutted out from the castle to hang over a large cliff that seemed to disappear into nothingness.

I gasped and backed away bumping into someone. I turned to find the demon. She was smiling at me and wearing a dark, blood-red gown. "I love this view," she said as she guided me back to the railing. I stared, a little shocked at seeing my sister's demon lord. She laughed. "Demon lord, huh? Can't say I hate it, but fortunately, I've never been promoted to that level and God willing, I never will."

"I guess I shouldn't be surprised I'd be dreaming about you."

"Well, you're not dreaming... I mean, you are but you're not at the same time. See, the only way a human can visit this realm is through a dream or death."

"So, all of this is real?"

"Yes, and no. It is a replica of a real place that I put into your mind. It's my place, my home."

"It's gorgeous."

"Thanks."

We stood for a moment and watched the planets pass overhead. "Why am I here?"

"We need to talk and I've got a party later so I figure this would be the quickest way to have our little convo." She looked at me and I looked at her until she said, "Technically, I'm not supposed to just take the soul of an unwilling participant. It happens, but it's frowned upon by the douchebags on the other side, so I brought you here to strike a bargain."
