But still a demon

Drayce unzipped his fly. His throbbing member sprang forth, relieved to be free of the confines of his trousers. He was fully erect and of admirable size and girth.

"Mmm, that looks tasty!" Fiona breathed, licking her lips with her forked tongue.

He knew what she wanted him to do. He knew what would happen if he put his cock in her mouth. His balls ached like they never had before. They wanted, no, they needed release.

"Let me suck you, Drayce," she beckoned. "It will be the best blow job you've ever had."

Drayce hand slid up and down his shaft. The pleasure he gave himself was better than any of the too-many other times he spent stroking himself to Internet porn after a long day's work.

Wait. Other times? That's it!

"No," Drayce replied.

Fiona stopped, surprised by Drayce's sudden refusal.

"You said my soul is pure, but I've masturbated many times in my life. That must mean that jerking off isn't a sin. If I let you suck me off, it would be lust, thus corrupting my soul and allowing you to take it."

Drayce stroked his cock several feet in front of Fiona, never moving closer. He pumped his cock with the energy of a teenager.

Fiona smiled wickedly. "Oh, you clever, dirty boy! You teasing me like that makes me so wet!"

The added arousal made Fiona's horns grow from her head; her large black bat wings extended to their fullest. Her two slaves thrust in and out of her so fast that a normal man's lungs would collapse. Her eyes, now bright red, stared into Drayce's while he kept stroking his cock. He was unfazed by her demonic appearance. Her beauty was eerily enhanced. The horns, the wings, and now the tail that wrapped around the throat of the man behind her -- oh yes, she was supernaturally sexy.

But still a demon.

Drayce let out a bestial roar when he reached the edge. Fiona screeched loudly like a banshee, her orgasm in full force, her energy magnetic. The two men moaned, unable to hold it back any longer. They sent their seed deep inside both of Fiona's hungry holes while Drayce shot his flying into the air towards her. Like a vacuum, she sucked in every drop of Drayce's cum, never allowing a single drop to touch the ground.

Drayce saw at first hand what happened when Fiona consumed a soul. The two men rapidly shriveled and shrank like raisins under a merciless hot sun. Their eyes dried to fine powder. Their hair turned pure white. Their skin darkened and collapsed around their bones. Their lifeless components fell silently to the ground.

Unsure of what to do, Drayce stood dumbfounded with his cock still protruding into open air, aimed at the unseen horizon.

"Mmm..." Fiona stood. She folded her wings behind her. "It has been centuries since I've tasted the cum of a pure soul. Such a sweet dessert after a large meal like this." She looked intently at Drayce's cock, still in the open. A small dollop of cum hanging from the tip of Drayce's penis slowly floated through the air to the tip of Fiona's forked tongue.

Drayce quickly put his cock back into his trousers. "Now what are we going to do about them? We can't leave their bodies here for the CPD to find. Cops don't like unexplained corpses."

Fiona flashed Drayce a smile. She raised her hands and clicked her fingers. In an instant, the bodies of the two men ignited like rags soaked in gasoline. The fire burned with such intensity that Drayce had to step back for his face hurt from the heat. The bodies were charred beyond recognition within seconds.

The flames slowly dissipated. Fiona calmly knelt down, puckered her lips and blew air from her mouth. The charred corpses disintegrated into ash, blowing through the air until there was literally no trace there ever had been two men.

She pointed at the pistol on the ground where she tossed it earlier. She snapped her fingers again. The steel weapon crumbled into rust.

"Ashes to ashes," Fiona said, winking at Drayce.

Fiona walked casually to her dress puddled on the ground. Her tail, wings, and horns all returned inside her body, leaving just a tattooed nude beauty in the moonlight.

"So where were we?" Fiona said as she slipped her dress back on.

Drayce stood motionless, trying to sort out all that had just transpired. He was almost mugged, then he watched two guys fuck Fiona, and have their souls ripped from their bodies, then set on fire and vanish without a trace. All of that, while experiencing the best orgasm he had ever given himself.

She stood in front of Drayce and clicked her fingers in front of his eyes. "Hello? Anyone in there?"

"Oh! Um. We were discussing terms. I think."

She gave him a stern look. "It's decision time, Drayce. Do you agree to our deal, or not?"

Drayce paused for a moment. He knew she had powers that he didn't yet fully understand. He also knew he had no one to turn to for help in finding Phoebe's killer. What choice did he really have?

"Okay, I'll do it." he replied.

"Great!" Fiona said, jumping up and hugging Drayce. "If you are certain of your answer, then kiss me. It's how we succubus seal these types of arrangements."

He was hesitant, but he leaned forward and gave Fiona a small peck on the lips.

"You call that a kiss?" she scolded.

"Fine." Drayce leaned in and kissed her passionately this time.

Their lips pressed together and fireworks exploded in Drayce's mind. The way her kiss felt was unlike anything he had ever experienced with Phoebe, which he was ashamed to admit to himself.

"That was much better. I'm actually impressed," Fiona said.

"Thanks, I guess." Drayce said.

Fiona looked at herself. "Whew, I'm sweaty and dirty from all that. I need a shower. Thankfully, my lair isn't far from here. Care to walk me home?"

Drayce nodded. There were still things he didn't understand, plenty more that he needed to discuss with her. Visiting her lair would be a good place to start.

And so they walked, Fiona's arm around Drayce's back and her head rested on his shoulder.

Here we are!" Fiona said.

"Here? But there's nothing here." Drayce was puzzled. A concrete wall?

They were under one of Chicago's many overpasses. The traffic roar was deafening. The fetid space showed no sign that anyone had been down here for quite some time. Moldy piles of litter and debris lay scattered across the uneven ground. This looked like home-sweet-home for a troll.

Fiona gave Drayce a sultry smile. "Looks can be deceiving. You should know that by now."

She placed her hand to the concrete wall. It responded vividly to her touch. Purple glyphs glowed like bright street signs and spun on the wall in a psychedelic clockwise whirl. The glyphs became a portal, a gateway, which opened to reveal a hidden room.

Without a word, Fiona stepped through the portal.
