An imp

You see a small creature with red skin, and a pointy tail come out of the bushes. It's an imp. A small, lesser demon

"Hello there miss" he greets you quite charmingly for an internal creature. "Would you perchance be trapped in this tower against your will?"

You slowly nod your head.

"In that case." he smirks "I think we can be of service to one another"

"What are you suggesting?" You query him, does he know of a secret exit you can use?

"I'll get you out of this tower." He proposed "I can use my magic to open a portal and get you out of here." He continued "But, I'm too pent up to focus my magic enough to create a portal. I need you to relieve me of this burden by making me cum."
