The Devil went down to Jons house

Jon got home and headed up to his room when his doorbell rang. Knowing that he was the only one home he went downstairs to get the door, He opened it and no one was there. He shut the door and turned around and standing there holding the stone was a lanky man of about six foot with long golden blond hair going down to mid back, he wore a black suit with a red silk shirt and tie, and red leather gloves. His features where worn and he had wrinkles looking like a well sixty.
"Who are you? And how did you get my stone?" Jon asked preparing for the worst.
"I'm he of the morning star, Lucifer" He said
"What seriously?" Jon asked only half believing him
"I bet you didn't know this but I got a wishing stone too, stronger. And if you'd care to take a dare, I'll make a bet with you. Now you've been pretty cautious,Boy, but give the devil his due: I bet my wishing stone against your soul, 'cos I think I'm better than you."
"I'm listening" Jon said intrigued
"I'll tempt you into using the stone for selfish means and if you are able to resist for a week you get this stone which will merge with yours giving it a major power boost"
Jon Said ""My name's Jon and it might be a sin, But I'll take your bet, your gonna regret, 'cos I'm the best that's ever been."
Jon blinked and Lucifer was gone
