"What exactly are you planning?" Ethan asked, looking at Vex suspiciously. He had to focus hard not to stare at her large breasts.
"I haven't got long before I burn up too much power to help you, so let's get right to it, I want to fuck," Vex purred. Ethan stared at her, his eyes roaming her body, but landing on her large semi erect cock.
"You want to..." He muttered.
"Oh don't worry darling, I don't expect you to want that, not yet at least," she chuckled. Ethan wasn't sure what she meant by the not yet, but he didn't have time to think about it was Vex span around and bent over the desk. She wiggled her firm, round ass and showed off her dripping wet cunt.
She didn't say anything more, but she didn't need to. The sight of her was too enticing for Ethan to ignore and he quickly dropped his pants, releasing his already erect cock. Standing behind Vex, he grabbed her hips and felt her soft skin. It was hot, way hotter than a normal humans skin, but not enough to burn him. He moved forward, pressing his cock against the entrance of her wet twat. It slipped inside smoothly and he groaned, it was unlike anything he had ever felt.
Her cunt was tight and hot, but soft and smooth. It gripped him with just the right amount of force, as if it was specifically designed to fit around his cock. The walls were like liquid silk. He buried himself inside her and wasted no time in fucking her hard and fast.
"Oh fuck... YESSS... God I've missed this, fuck me harder," Vex purred, gripping the desk as she pushed herself back onto his cock. Ethan obliged, finding himself picking up the pace and pounding her harder and faster than he thought possible. Vex moaned loudly, begging for more as she shuddered in orgasm. Her cunt squeezed his cock and Ethan knew he wasn't going to last much longer.
He noticed Vex reach down, stroking her cock as he pounded into her. He didn't know why, but he had an urge to touch it. He reached around and grabbed her cock, Vex grinned and removed her own hand, enjoying the sensation of the man fucking her cunt and stroking her cock. She moaned as another orgasm approached and Ethan groaned, his own on the verge of exploding.
Together they cried out, Ethan emptying his load inside the demon as she shuddered in front of him, her own cock emptying its load over the desk. Ethan's orgasm seemed to last forever, he could just register in his pleasure riddled mind that despite the fact he had stopped moving, the walls of Vex's twat seemed to be moving on their own, milking his cock for every drop. Eventually it subsided and he collapsed onto her back, totally spent.
"You have no idea how long I've been waiting for that..." Vex sighed. "But time is up, I have to go."
Ethan nearly face planted his desk as Vex suddenly vanished, no longer supporting his weight. He just managed to catch himself and stood up straight, suddenly full of energy again after being made jump like that.
"Fucking hell, a bit of warning next time?" He groaned.
"Ha! Sorry, I just didn't want to use up any more power," Vex replied from inside the phone.
"It's fine," Scott grumbled.
"This is starting to become a very lucrative partnership. I've not had anyone pick up magic so quickly or provide me with as much power as you have in centuries," Vex commented.
"I'm glad it's working out for both of us," Ethan replied.
"I've got a spell for you, it's a little risky, but I think you can manage it," Vex suggested.
"Go on..."
"It's the more powerful version of the arousal spell, it'll make them uncontrollably horny. I wouldn't leave it active constantly though, people have been known to die of hunger and thirst because of it's effects," Vex warned.
She explained how to take the spell focus he had already created and improve it's power, which surprisingly only required carving some additional runes on it and adding a single quartz crystal to the top side of the focus. He activated it the same way as before and suddenly felt dizzy for a moment. He steadied himself and after a few seconds he felt better.
"Well, you didn't die, that's impressive," Vex giggled.
"That would have been inconvenient," Ethan agreed. The fact he had almost just killed himself didn't seem to bother him, he was just pleased the spell had worked. He heard footsteps on the landing and he stepped outside to find Ruby rushing to her room.
"Wait," Ethan called after her. She quickly stopped and turned to face him.
"What do you want?" She snapped. Ethan could see she was extremely aroused. The front of her panties were soaked and her juices were running down her leg as she subtly rubbed her thighs together. He knew she wanted to go to her room and masturbate, but her heightened obedience was making her obey his command to wait.
"Play with yourself right now," Ethan commanded. He knew normally that would result in her telling him to fuck off and call him a pervert, but he was hoping the obedience combined with the arousal would be enough to make her do it. He watched her face as she was at war with herself. She knew she should be angry at him for what he just said, but equally she couldn't ignore how horny she was.
Looking away, she shoved her hand down her panties and began to stroke herself in front of Ethan. She turned and leaned against the wall as she plunged two fingers inside herself and moaned loudly. Ethan smiled as his cock grew hard. Feeling bold, he unzipped the front of his pants and freed his erection, stroking it slowly as he watched Ruby. She avoided his gaze, but he could tell she kept glancing at his cock from the corner of her eye.
"Look at me," Ethan commanded.
"Fffff..." Ruby began before she looked up, staring him straight in the eye. Ethan could tell she wanted to look anywhere but his face while she was busy fingering herself, but her desire to obey was too strong. They locked eyes as Ruby began to moan loudly, her body twitching occasionally as she grew closer to orgasm. Ethan began to stroke himself faster, never breaking eye contact. The feeling of power he had as she was unable to look away increased his lust substantially.
Ruby came first, crying out loudly as her body shuddered. Her legs wobbled and gave out, causing her to slump against the wall and slide down it as her legs pinned together and trapped her hand, her fingers still working inside her. Ethan saw his chance, he walked over, Ruby still looking at him with wide eyes as he stood over her. With a groan, he came, coating her face with his seed. She finally closed her eyes, the desire not to get her step brothers cum in her eyes overruling her desire to obey, but she didn't move away. She just continued facing upwards with her eyes closed as he painted rope after rope of his sticky fluid across her face.
Ethan grinned as he looked down at the mess he created, her face was covered and some had even landed in her red hair. He noticed that Ruby had begun masturbating again, her fingers working in circles on her clit. It seemed despite her recent orgasm, the spell was keeping her extremely horny. It wasn't having the same effect on Ethan though as his cock began to soften. Still, he watched as she sat against the wall, covered in cum and masturbated herself to another orgasm that left her laying on the floor gasping for breath as she trembled in pleasure.
"Such a slut..." Ethan commented before returning to his room. He removed the crystal from on top of the focus and broke the spell. As much as he liked having Ruby desperately horny and willing to let him cum on her face, he didn't want her dying from being unable to do anything but masturbate.
A few minutes later Ethan's door suddenly burst open. Ruby was stood there looking furious, her face red from washing and her hair still wet. She stared at Ethan with fury in her eyes.
"What the fuck did you do to me!?" She screamed.
"What do you mean?" Ethan asked, feigning ignorance.
"Just then, in the hallway, why couldn't I stop myself from... You know! And why did I suddenly let you do something so disgusting to me!?" She yelled.
"Calm down," Ethan commanded. Ruby seemed to deflate, the tension in her shoulders dropped and her expression went from pure hatred to only mild contempt.
