Give in to the Mystery Girl

David decides that the Mikasa Coplayer can wait, this matter was a little more pressing.

"Oh please, have mercy. If you rub my staff like that I'll be entirely under your control."

"Oh, don't worry little mage, under my control is exactly where I want you to be."

The Mystery Cosplayer turns David around and pulls him close as she puts her hand down his pants and begins rubbing his "staff." Now David can get a good look at the voice in his ear. The girl is dressed like some sort of buxom demon, with a pair of horns In her raven hair and a skimpy outfit that looks more like a dark purple bikini than any sort of armor. Her massive tits stretch the top of the bikini armor almost to bursting, threatening to pop out at any moment. The tiny bottom can barely cover her curvaceous ass, and the fake devil tail that hangs off the back sways seductively as she moves her hips. David see a gleam of devious excitement in her eyes.

"Follow me hero, I will take you to my lair and show you exactly what a succubus can do."

David follows the curvy succubus as she leads him away from the convention center and to the hotel. They take the elevator up to her floor and she lets them into her room. Once inside the succubus orders David to strip. Nervously, David obeys. He has never done anything like this before. Once David was fully naked, the succubus roots around in a nearby suitcase and pulls out what looks like some sort of leather strap with a buckle.

"Turn around, prey. Put your hands together behind you."

David obeys her, and once his hands are clasped behind him the succubus bind his wrists together with the leather strap. The girl circles the bound boy and observes her catch. David's cock was half erect with anticipation. The succubus smiled and began to rub the soft member with her hand.

"My, what a perverted boy. Is my little mage getting excited by the thought of what I am going to do to him? I'd almost think you wanted me to suck out your soul."

Pushing David back onto the bed, the succubus kneels down at the foot of the bed and starts slowly stroking David's cock. She looks up at David watches as his face contorts with desire as she slowly and methodically strokes up and down his shaft. He starts to pull on his bonds as she begins to play with just the head. She seems to be taking pleasure in teasing him.

"Oh my little mage, you look so pent up. Your thick staff is so hard in my hand, and you smell so delicious. I bet you just can't wait to have my soft lips wrapped around you, sucking the energy out of you with my tongue caressing your shaft."

"Y-yes, please..."

"Then I want you to beg for it. Say: 'Mistress, I want you to suck my soul out through my perverted dick.'"

David moans as she licks his frustrated penis from base to tip.

"P-please, Mistress, I want you to s-suck my soul out th-through my perverted dick."

"Good Boy."
