She follows his instructions

"Alright, but make it quick. We have work to do," Katarina said coolly. She had tried to sound non-nonchalant but really she was nervous with what was about to happen.

"Yes boss! Open up," Xeblec said gleefully.

She opened her mouth per the imp's instructions. Instantly the top of the imp's cock pushed towards her and she realised that she needed to really stretch to fit it in. The imp's girthy cock pushed at the sides of her mouth and her lips stretched lewdly.

Angry that the imp hadn't really given her any warning she looked up at the imp, trying to stare daggers at him. Xeblec was looking at her and smiled when he saw her looking at him.

"You look so beautiful, defiant like that yet still sucking my cock, he said. "Stars this is the best night ever!"

Katarina moaned in protest at his words but was unable to say anything as the demon shoved himself into her mouth even further. The entire tip of his cock was just about to make it all the way into her mouth. A bit of his semen dribbled out and she got a small taste of that delectable seed. Opening her mouth wider, the head passed through and the imp slammed his cock to the back of her throat in all in one go. Cum spattered to the back of her throat and Katarina jerked her head back, gagging and coughing. A string of saliva and cum fell from the tip of the imps cock and her lips, landing on the ground in front of her. She looked at it for a moment when she recovered.

"Hey now, you're going to have to get used to this. Aren't you the one who is in a hurry anyway?"

"Doesn't mean I have to like it imp," Katarina shot back. Despite her words though that brief taste of his cum must have done something to her again as she felt hot all over, emanating from between her legs. She placed her hands on the floor on either side of her, shifting her weight so it was easier on her knees and butt. Her earlier embarrassment replaced by her anger at Xeblec. "Lets get this over with then."

Opening her mouth again, this time she stuck her tongue out, thinking it would be easier to open her mouth wider like this.

"So you do want it!"

Before she could retort the imp once again shoved his penis into her mouth. This time he didn't push in slowly and his cockhead had already passed her lips. Something grabbed the back of her head, roughing up her long red hair and pushed her from behind.

Katarina struggled not to gag as his cock filled her mouth and made its way to the back of her throat. She was determined not to show weakness to the imp as she stared defiantly up at him. Tears welled up in her eyes as the imp pulled on her hair this time and the back of her throat got a very brief reprieve before he pushed again and his cock filled her.

With that thrust she got a little taste of his cum again and she moaned at the taste. Xeblec simply grunted and a little bit more of cum leaked out. He picked up the pace and started to thrust in and out of her mouth slowly. It was difficult to see through the tears but Katarina saw that he wasn't thrusting his entire cock in her mouth yet. There was still about half of it left!

I wonder if I'll ever be able to get the whole thing

At some point her fingers had found her pussy and she was running them in circles around her clit. Not actually touching the small bundle of nerves but teasing herself. The attention sent small jolts of electricity throughout her body, it felt so good, especially when compared to the imp fucking her mouth.

Xeblec sped up once again and started to thrust faster. His huge cock had driven her tongue back into her mouth and even with the speed that he was thrusting in and out she could feel the outline of his cock. She could feel the change in thickness of it between the head and the shaft as well as the thick vein on the underside. Her mouth had molded into the shape of his cock and really she was just a receptacle for his cum.

She moaned continuously now, actually enjoying the experience. She looked up at the imp again and saw that he was leaning back with every thrust, not even looking down anymore. Katarina felt this hands on the back of her head push harder and Xeblec humped into her face.

Her throat stretched, accommodating for the last part of his cock as her nose hit his hairless pelvis. The imp yelled something incoherent and thick cum exploded out of his cock. Much more than before Katarina gagged as it filled her throat. There was so much that she felt like it was going to go up her nose too!

She swallowed, and immediately swallowed again. Partly trying not let it go up her nose and also partly because she couldn't stop.

Suddenly the imp pulled back before she could drink any more of his cum. Thick ropes of his seed flew into the air before it landed on her face and hair. It seemed endless as it coated her forehead, just under her nostrils and her chin. Some of it found its way on her hair as well as in the small valley between her pale breasts.

The imp looked down at her now, watching her fingers which would have been a blur over her pussy. Rubbing it for all she was worth. Katarina was openly moaning now, the effects of the demon cum making her abandon her thoughts other than the need to climax.

"Ahhh that was brilliant. Best I've ever had I think.... Oh let me help you out here."

Katarina felt something grab her. She opened her eyes and looked down. Xeblec was holding her wrist away from her pussy, he made eye contact with her again. He grinned, then his other hand reached out to her soaked pussy, pulsing on the edge of orgasm and leaking more juices than ever before.

FLICK

Katarina screamed.
