Yes

After a short while to think about it, you come to the conclusion that making an imp cum is a worth him helping you escape this place. At least he's offering you a deal, who knows what other beastly creatures lurk in this tower, and how you'd fare in their company.

"Alright." You nod "I'll do it."

A fittingly devilish grin grows on the imp's face as he removes his loincloth. Your eyes go wide as you are greeted with the sight of his cock. It would be considered large were it on a human, but on the imp's small frame its positively huge! He steps up onto a log so as to give you an easier time of reaching his cock. How thoughtful of him.

You position yourself in front of him, take hold of his impressive manhood and begin to stroke it. You feel it quickly swell with his infernal blood and rise, almost hitting you in face. The imp leering down at you as you work is quite intimidating despite his otherwise small frame, its as though you can feel his presence weighing down on your mind, infiltrating your thoughts

Only now do you notice the creatures barbed tail waving back and forth behind him. You hope that it's just for show, it looks like you wouldn't want to be on the receiving end of its sting.

"You should use your mouth too" He suggests, trying to be coy

"And why would I do that?" You respond in kind.

"Because the quicker I cum, the quicker I can get you out of here"

You find yourself agreeing with the imp in your mind. He does make a compelling argument.
