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.
