Glad people are the story so far, although it seems I upset a couple of people with Ethan being fucked by Vex, which I should have put a clear warning for, so I apologise for not doing. Although she did threaten to do it enough times to hint it was coming. Regardless, here's a warning: There will be more futa content, futa on male, transformation, gender swapping and other kinky things coming that may not be everyones cup of tea! So be warned and if that stuff isn't for you, stop reading here. For the rest of you, enjoy!
Ethan woke up and sighed. Ruby and Anna were snuggled up next to him, while Vex was curled up at the end of the bed. He was still pissed with her, but he knew he'd need her help. She had told him he was part demon, it was the only thing she could think of that would explain how he could use demonic magic and the markings.
Except, that was apparently impossible. A demon was basically a human, but without a soul. A human soul was what kept a person alive, if the soul died, so did they. Demons on the other hand were kept alive by magic itself, their bodies were saturated in it, which was why if a demon ran out of power, they died.
The issue was, according to Vex, that a human soul and a demonic body couldn't co-exist. She likened it to putting a ball of fire into a tank of gas, the whole thing would just burn up. Some how though, Ethan was proving that theory wrong.
He wiggled his way out of the two women and climbed out of bed. It was still early in the morning, so he went downstairs and prepared breakfast for everyone. He paused when thinking about how much to make, did Vex need food? Did demons need food? He assumed no, but made some anyway just in case.
He returned to the bedroom to wake the others only to find them already awake. Ruby was riding Vex's cock, while Anna was watching and masturbating. Ethan walked in and grabbed Anna, pushing her backwards and moving between her legs. She grinned at him as she grabbed his cock and guided him inside her. They began fucking hard and fast, Ethan's new strength and stamina taking over leaving Anna incapable of little more than holding onto him tightly as he pounded her into the mattress.
It wasn't long before Ruby was begging Ethan to let her cum, she still needed his permission and he granted it. As the words left his mouth, Ruby shuddered and screamed loudly in pleasure. Ethan was amused by how loud she could be when she didn't have to stay quiet. The pleasure overwhelmed Ruby and she flopped sideways as her eyes rolled into her head. Vex looked annoyed as her cock slipped free of the now barely conscious red head.
Ethan grabbed Anna and rolled over, pulling her on top of him. She began to ride his length, taking every inch inside of her as she moaned and grabbed her breasts. Vex moved behind her, straddling Ethan's legs as she pushed Anna forward, exposing her ass. Anna simply waiting as Vex pressed her cock against her tight asshole and pushed the head inside. With a single thrust, both Vex and Ethan were buried to the hilt inside Anna's two holes and she groaned in delight.
Vex held the woman's hips as she began to thrust, while Ethan thrust up into her. The dual stimulation sent Anna wild. She had done double penetration with toys before, but never two cocks. The feeling of two hard cocks inside her was better than any toy could feel. She dug her nails into Ethan's chest as an orgasm washed over her, the first of many to come.
After Anna had her fourth orgasm, Ethan felt his own approaching. He grunted as his balls tightened and he began emptying his load inside his step mother. Vex asked if she was allowed to cum too, but he denied her. Anna could barely talk by this point and just mewled happily as she felt his seed fill her insides. Once he was done, Ethan ordered Vex to pull out, which she did as Anna rolled onto the bed next to her daughter.
"Breakfast is ready, although it might be cold now," Ethan announced getting up. The two women slowly crawled from the bed on shaking legs and followed him and Vex downstairs.
They ate their breakfast and as it turned out, demons did in fact eat food. Not that they needed to, but it was still enjoyable apparently. At least that's what Ethan gathered from how fast Vex ate and the fact she finished off both Ruby's and Anna's left overs. Although, it was her first meal in centuries, so he could understand her enthusiasm for cold pancakes.
"So what do you want us to do today?" Ruby asked.
"Anna you need to continue going to work, things need to appear normal for now and we still need the income. Ruby, I have an idea for you, but we'll need to go shopping first. So today you can spend the day tidying the house. As for you Vex, you're going to teach me everything I need to know about demons and magic," Ethan explained.
The women all agreed and set to their tasks. Vex and Ethan returned to his room and she gave him a crash course on demons, how they use magic and the most common types of demons. She explained that demonic magic was mostly intuitive, you just thought what you wanted and it happened. They had much more control over magic than humans and didn't require ingredients or potions, although they did use incantations on occasion.
All demons required one thing though, magic. They didn't naturally generate it, nor could they channel it from the environment like humans could. Different demons got their power from different sources. Some examples vex gave were demons of lust, like herself, who got theirs from pleasure. Demons of chaos got theirs from chaotic events, things from someone missing an appointment to a house fire could all provide power for them. Demons of greed got their power from people being selfish. Basically any act humans did, demons had found a way to exploit it.
Vex asked Ethan to lay down on the bed, which he did. She straddled his hips, his cock growing erect into her ass as hers lay across his stomach. She ignored his cock though and suddenly plunged her hand into his stomach. Ethan's eyes went wide as he watched her hand disappear into his abdomen. It took a moment for his brain to realise, there was no pain. Nor was there any blood or wound and he realised her hand was inside his stomach, but it hadn't broken his skin. She was using magic of some kind.
"Keep very, very still," she warned as she began to move her arm. She closed her eyes and focused for a moment before quickly withdrawing her hand as if she had touched something painful. It reminded Ethan of ever time he had accidentally burned his hand on the oven. Vex clutched her arm defensively, looking down at Ethan with fear in her eyes.
"What is it?" He asked.
"You're not possible..." She whispered.
"What? What is it? Tell me!" Ethan commanded.
"Your soul, it's not like anything I've ever seen. There's a technique of measuring someones capabilities of magic, to check their upper limits as it were. This is the theoretical cap on the amount of magic a person can use. You though, you don't have that cap. Your soul feels like ocean with no bottom," Vex replied.
"So what? I can use a lot of magic? Why is that so bad?"
"No, don't you get it, that shouldn't be possible. Everyone has a limit, even demons," Vex replied, her voice still filled with fear.
"So I could become stronger than any demon?" Ethan replied with a grin.
