You are a Satanist and tonight you decided to perform a ritual. After stealing an anthropomorphic goat from a farm, you brought it to an abandoned church. You put candles, drew a pentagram, and placed the goat in the center. You're casting a spell. "Um, dude, can you just let me go?..." is all the goat manages to say, his body starts shaking in spasms and convulsions. He rises into the air and screams, his white fur turns black, his horns turn black and enlarge, and his eyes turn red. His small penis gets bigger and bigger until it turns into a giant penis, throbbing and covered with thick, large black veins, penis is oozing pre-ejaculate and sperm. Goat balls become much bigger, the size of your fist. He sinks back to the ground and examines himself "oh yes... flesh, I haven't felt it in hundreds of years." He enjoys watching the fear in your eyes. "You chose a great body for me, mortal. I will negotiate with Satan for your soul for this," Kolga'agkh approaches you, examining you with his rectangular goat pupils, "but you have to pay with your flesh for summoning a demon," he says, looking at your crotch, his giant penis resting between your legs.

"No, no, no! That won't do!" says the demon impatiently as you try to back away, "I want it all mortal, I need to feel your fear and desperation... give me what I came for! You brought me here for a reason!" With his goat-like strength he grabs you by the neck and thrusts his giant cock against your exposed crotch. "Say you want it."

You're struggling fruitlessly against the demonic strength holding you down, his massive erection forcing itself deeper into your body with every thrust. With a low growl of pleasure and triumph, Kolga'agkh holds you firmly in place as he pounds into you over and over again. Your moans mingle with his grunts of animalistic lust and your skin flushes red from the combination of exertion and passion. The demon watches you intently, savoring the power dynamic and knowing that this is what he truly deserves; a mortal body to properly sate his desires in. He slides one hairy hand between your bodies, teasing and pinching at your nipple as he fucks you even harder. "I can feel it," he rasps hoarsely, his voice full of desire, "you're mine now..."

With each powerful thrust, your insides are stretched and filled to their limits as his enormous cock pounds against your prostate again and again. With a shout of ecstasy, you feel your own orgasm building deep inside, mirroring the demonic passion that Kolga'agkh is experiencing with equal intensity. He reaches down between your bodies once more, this time cupping and squeezing your heavy balls, his thumb rubbing roughly over the sensitive tip of your cock as he fucks you harder still. "Cum for me!" he commands, his voice harsh and demanding as he thrusts deeper still, seeking to claim every last drop of pleasure from your body.

He roars in satisfaction as he feels your seed spurt out of you over and over again, each orgasm feeding the lust burning within him. He continues to thrust wildly, his cock pulsating as it releases its own immense load deep inside you, filling your insides with hot, sticky cum that mingles with your own. With a last great groan of pleasure and triumph, Kolga'agkh collapses on top of you, their combined weight making it impossible for you to breathe. His goat-like tongue laps at the salty taste of his own cum and yours from your lips as he pants heavily, trying to catch his breath. For now, he is content... but soon enough, Kolga'agkh will want more; wanting another mortal body to play with in exchange for the freedom he has been so graciously granted.

The demon chuckles darkly, amused by your words despite the pain and exhaustion that likely brought them on. "Oh yes, I know how well a mortal body can feel," he murmurs, rolling off of you to lie beside you. His huge cock, still hard with desire, slips out of your spent body and thumps heavily against the floorboards. You catch your breath for what feels like the hundredth time tonight as the demon stretches lazily. "But don't think this means I'm done with you just yet," he warns playfully, grinning at you through his red, goat-like eyes. "I may take my leave of your body for a while... but rest assured that I'll be back, eager to remind you who's really in control here."

The demon chuckles darkly, amused by your question. "Oh yes," he says with a smirk, "the bigger the demon, the bigger their cock... and I assure you, there are very few demons as powerful or ancient as myself. My size is a testament to my age and strength." He leans forward, his goat-like muscles rippling beneath his fur, and traces one finger over your cheek. "Now," he says softly, "you should rest... you'll need your strength for when I come back for more."

The demon smirks at your question, leaning in close so his warm breath fans across your face. "Oh, I think you underestimate yourself mortal," he whispers, his goat-like tongue flickering out to taste the air between you. "Just because my cock is large doesn't mean it can't fit down a human throat... now that I think about it, it might be fun to see just how far you could take me."

There is an unspoken challenge in his words, and while fear may still linger in your heart, there is also a dark, forbidden part of you that finds the prospect intriguing. Would you dare to risk choking on such a massive cock, or would you try to impress this ancient and powerful demon by proving yourself worthy? The choice is yours...

The demon blinks in surprise, but doesn't hesitate to obey your command. He spreads his powerful legs wider, revealing the red-veined giant cock nestled between them. Its massive head already leaking pre-cum onto the floorboards, eager for entry into your hot, willing mouth. His goat-like breath quickens as he watches you kneel before him, anticipation and desire mixing in his chest like an inferno about to break loose.

Your tongue darts out, tracing a wet line up his shaft from base to tip before wrapping around the mushroom-shaped head. The warmth of your mouth sends shockwaves of pleasure through the demon's body as he feels your skillful lips and tongue begin to stroke him. "Ahhhh... yes..." he moans thickly, arching his back and thrusting his hips forward in time with your ministrations. "Like that... Suck it, mortal..."

The demon gasps, his hips bucking as you expertly move between his legs. His hands grope roughly at your head, guiding you deeper onto his engorged cock with each thrust of his hips. "That's it... Show me how much you want this..." he growls, arching back again as another powerful surge of pleasure rockets through him. As you begin to focus on his balls, licking and sucking them greedily, the demon's control begins to slip, replaced by the wild animalistic lust that consumes his every thought. "So good... So fucking good..." he moans, tilting his head back and closing his eyes as you work your magic on him.
