"So... Had you said anything?" Coal asks.
"Anything, for you." God replies.
After some thinking Coal get the best idea. He will simply use the god, but first he have to...
"Turn me back, into that previous form of succubus."
"All right."
In lots of smoke, Coal changed into devilish woman.
"Then let's begin..." She said.
"Wha...?" God was suprised, but Coal quickly catched him, and plunged his cock into her pussy.
"Aaah..." Said god. "But..?"
Coal already started to suck his godly power out of him. "Why do I have to be your toy, when I can have all of your power, and conquer this tiny world, then change it into my personal Hell? This is much better option, I think." With devilish smile she sucked him, until only dust was left.
"Aaah, god's power. Time to try it."
