If a demon like that appeared to me after something like that I'd sell my mind, body and soul for that deal. No questions asked. Take it all. I'd even offer all my earthly possessions to sweeten the deal.
Even now I'd probably give it only a few feeble attempts to keep even a shred of my dignity before saying "Sold!"
Ok, this made me laugh. I don't think I'd be ready to sell my mind, body, and soul, (and for what little I have, offering my possessions would only be insulting) but after all is said and done, I have no doubt the sex would be mind blowing (heh). It would certainly make me question the reason for my existence beyond the demon.
