"Or maybe your little brother?" I grinned at Runt in the mirror. "Do they have demons in Junior High?"
He grinned back. "Maybe not yet, but I can certainly fix that." He shifted behind me and I felt the head of his swollen cock brush my buttocks and then slip into the crack over my anus. "You sure you want to do this? Becoming a demon is purely voluntary, but once you head down this road it's pretty much impossible to go back."
That made me think. "I don't know what a demon is. Never really had much belief in the Heaven and Hell thing. But I don't want to burn in Hell if it does exist."
Runt pressed a little harder, sliding his arms under mine and wrapping them around my chest in a hug. "It's way more complicated and simpler than that religious junk. Hell is pretty much just being stuck here. People who focus on the physical, on things and personal power and sensuality keep coming back to this place. The ones that can get past all that move on to another place."
"Heaven?" I asked uncertainly.
He shrugged, most of the expression hidden behind me. "I guess. I mean, I pretty obviously follow the sensual and physical path, so I've never seen whatever the next place is. I'm happy enough right here."
"Just what is it you do?" I began to feel a little nervous. His cock tip was pressed hard against my anus, not pushing in yet, but starting to stretch the opening. "What would I do?"
Runt chuckled. "Give people what they want. Sex, youth, wealth, beauty, bestiality - we satisfy the dark desires and hidden longings. And that helps bind them to this world."
"Like what you are giving me?" I stared in the mirror at my perfect reflection. Being stuck here didn't seem so bad, but I didn't like being just another of his victims.
"Not quite." Runt gripped me in a tighter embrace and I gasped as the head of his cock suddenly drove past the tight ring of my sphincter. It hurt, but the pain and heat throbbed up into my body becoming curiously pleasant. He held still, the insertion a tease. "I'm giving you what you want, but you will also gain the power to do pretty much anything you want to yourself or others. You will become a demon like me. Where they will die and start over again and again, we remain. But we can be whatever we want."
I yelped as the handsome young man suddenly transformed into a huge Great Dane whose forelegs were clamped around my sides, its pointed cock partly inside me. The Dog seemed to grin, lolling its tongue out for a moment before suddenly swelling huge and dark. The forelegs became massive black-furred arms that hefted me up like a child as Runt shot upward. Coarse fur bristled against my back, and I screamed as the dog cock swelled out into what felt like someone's fist driving into my anus. I was being held by a massive, humanoid bull. A minotaur. The stink was powerful, the dull-eyed brute drooling slightly on my shoulder. Then the monster shrank back, keeping most of the fur, but now goatlike instead of bovine. The easing of pressure made me weak and I sagged, only to feel a pointed cock sliding deeper into me. This new shape stank of the barnyard, of sweat and sex and onion grass and piss. Yellow goat's eyes stared out of a very bestial head, curved horns pale against the black fur. The hands pressed against my chest were thick and three-fingered, with a cool hardness more like hoof than flesh.
The goat-thing bleated "Do you want this? Or do you want to enjoy the changes but stay human? You need to choose now." Its cock pushed in further, more than an inch inside me. It trembled with the effort of holding back.
I wondered why Runt didn't change back to his handsome self, and then realized this goat-thing was probably what he really was. I was shaking in its grasp, terror and desire warring in my head. I thought about my life, about the concept of transforming other people in order to keep them trapped here, of the concept of actually becoming something out of legend and horror stories - a demon. But Runt wasn't horrible. And giving people what they wanted was really their choice, wasn't it? But he hadn't asked me when he changed me. Yes, I wanted it, but I had not spoken the desire, or even consciously thought it. He had acted on my subconscious desires, and everyone can get into trouble when that happens.
Runt seemed to be straining, and I realized he was probably fighting the urge to finish plunging into me, resisting the need to thrust what was probably a large goat cock hard and deep. I had to decide, now.
"Runt, I might regret this later, but I...."
