Eternal bliss

You are tired of fighting.

You are tired of being afraid.

But above all, you really want eternal bliss.

As you walk over to Lilith, she smiles, licking her perfect lips. "Drink from me, lay with me, serve me!" She offers an engorged nipple, leaking black milk.

You drink deeply of her sweet nectar, damning your soul and possibly all of humanity. And it feels fucking great.

Finally, you release the nipple with a pop. You feel incredible. You take your clothes off in a hurry and survey your mistress. Her glorious red breasts still leak her milk, and her pussy drips with damnation, and damn yourself you do, right up to the hilt. As soon as your cock is buried within Lilith's fiery depths, you cum in waves. Your soul is lost immediately, and with its loss, your change is triggered.

Your skin erupts in supernatural flames; you feel only pleasure. Just as suddenly, the fire extinguishes itself, leaving your skin a perfect crimson. Your frame ripples with muscles, and Lilith coos as your cock reaches twelve inches. Finally, your horns, tail and wings burst forth simultaneously, and you ride out yet another orgasm.

"Take the stone and corrupt it; then corrupt every last one within the church," your mistress commands.

"Yes, my mistress," you reply, pulling your cock out of her snatch and bowing as you are whisked back to Earth.
