I light the last candle in the circle around the symbol painted on the floor, the flickering glow of the flames filling the room with a warm and eerie glow, one that constantly changes, shadows dancing madly across the walls. After so long it's finally ready, years of proportion and research, doing everything to make this ritual happen, even degrading myself for the pleasure of others, gangbangs, public acts, filthy beds and motels, piss drinking and ass rimming, crawling on alls, dragged around on a leash like an animal, tied up and chained and caged, the plaything of others, consuming the cum of 666 men, but it will all be worth it, and I won't lie I did enjoy it. Tonight I summon a powerful demon of desire, lust, pleasure and pain and perform the ritual for everlasting pleasure, if everything goes as planned I'll soon be immortal and in a constant state of sexual bliss. 

I stand in the centre of the symbol and chant the incantation, as I do I remove my robe revealing my shaven and naked body, one marked by my many sexual acts, whip marks and burns permanently reminding me of my encounters, as I do another man comes into the circle and I feel his cock as it enters my ass, one that is used to being penetrated and takes it easily, although I have to struggle to keep chanting as he moves inside me, my chanting growing louder as he thrusts deeper and harder into me, my cock growing hard as I shout the chant as I cum, my cum spraying over the symbol, as it does a red flaming light glows beneath us both. A part of me feels sorry for the man I convinced to take part as his cock remains deep inside me, his body frozen in shock and fear, he just thought I was kinky, he never knew any of this was real but I needed a sacrifice, and he was willing to enjoy my body.

"I sense one who seeks eternal pleasure." The demonic voice echoes in my head from all directions. I’ve finally done it, I’ve succeeded in my goal, eternal pleasure is mine to obtain.

"You have made the appropriate offerings and done the deeds, I accept your soul and bind it to my service forever, to feed off of your pleasure, fuelling my growing power." I feel a burning wave of energy flow over my body, I cry in pain as my body changes, the pain slowly becoming pleasurable, an overwhelming hunger and desire growing inside me, my mind unable to think as it consumes me. 

"You like the pain don't you, that's one of my gifts, pain and pleasure are now the same, your body feeds off of it, it lives off of it, luckily for you I'll give you plenty of both." I barely notice as the man behind me cries out in pain as his body grows and changes, his skin turning a dark red, bat like wings bursting from his back, tearing through the flesh as it does, horns and spikes piece his skin and his cock buried deep in my ass expands and pushes deeper than before, stretching my ass painfully, causing me to cry out in pain, my wrapped mind enjoying the feeling as I'm lifted off the ground, impaled on the large demon cock as it rips my ass open. I hang limply, moaning in both pain and pleasure, slight fear growing inside me, this wasn't what I was expecting to happen. I feel burning metal around my throat, wrists and ankles, screaming in pain as it burns my flesh, the chains attached to them pull tightly in different directions, stretching out my body, my back and joints popping as I’m stretched uncomfortably, like a prisoner on the rack, the burning collar choking me slightly, my arms and legs spread wide apart, secured to the demon who is deep inside me, his cock slowly and rhythmically moving, I can't help but struggle and moan in a mixture of pain and pleasure. His rough scaly skin cutting onto my back as I do. 

"You will forever keep my new demon happy, his eternal cocksleeve, an immortal slut always lost in the blissful pleasure of their painful and sexual existence, a horny, lustful, needy whore for the beast it is bound to, a beast that will never be satiated, who will constantly fuck you, their cock never tiring or going limp. You are now mine forever, willingly damned to my realm, never to be freed. Enjoy your eternal existence being fucked my soul bound slave." I feel fear as I realise what I’ve done, I pull on the still burning metal restraints as the cock in my ass begins to move more violently, the small spikes along their cock shredding my insides, as it tears open my ass even more as it forces itself deeper into me. My fears slowly drowned out by my moaning of bliss and pleasure, my hard cock cumming as I sink into the glowing fiery symbol and travel to my new home, forever lost in the demonic realm. 

Epilogue:

I moan cocooned in the demons wings as they wrap around me, his huge cock thrusting deep into my ass, my limbs restlessly pulling on the chains holding me firmly to my eternal lover, not in an attempt to escape my fate but instinctual as I writhe in pleasure and pain, my mind lost in a haze of horniness, lust, desire, hunger and bliss, always craving more as his cum fills my sweating body, my stomach swelling as he pumps his huge load inside me over and over again, my own cock erupting in a body shaking orgasm. For the briefest of moments my mind clears, the heat, the screams of agony from other damned like me, the terrible pain of my impaled body, the hunger of my starvation, the thirst of my dehydration, the horror of my existence managing to reach the surface of my broken mind, I pull frantically on my red hot shackles, my panicked movements only causing me pain as I dig the burning metal deeper into my flesh, pulling my joints and choking my throat, rub my back against the rough skin of my demonic lover, tearing my skin and pushing the cock impaling my ass deeper, the movement causing my lover to become aroused once more as my body processes the pain as pleasure and as he begins to fuck me once again I'm lost in the fog of blissful lust, my mind nothing but a horny slave, a willing whore and cocksleeve for my eternal lover, bound to him not just physically but mentally, constantly craving his cock, addicted to the pleasure and pain he brings me. I got everything I ever wanted and I will gratefully serve my role forever, pleasuring the beast I serve, rewarded with the pleasure and pain it brings, desiring nothing else.
