Stepsister Succubus 9
As wild as his life had become, Marc was happy there was still normalcy to it, like sitting on the couch and playing games in the living room when no one else was around.
His dad was out with friends on a fishing trip, one he'd been planning for some time. One Maria had been on him to remember, seemingly because she wanted him to take a vacation for himself for a change.
He always seemed sheepish whenever she reminded him, especially when she gently chastised him for seemingly forgetting.
Meanwhile, Sofia had gone on a 'day out' with Chaney, though Marc had an idea what she might've been getting up to with his girlfriend. They'd definitely regale him the details later. Maybe even 'reenact' what they did, and have him join in. Or maybe they were doing something normal, like he was. Probably both.
He smirked at the idea, but his brow quickly furrowed as he came to a particularly challenging section in his game.
He was focused such that he didn't notice Maria come down from upstairs, until she spoke on her way into the kitchen.
"Not out with Chaney?" she asked.
Maria and his dad had met Chaney by now, and they thought her delightful. No issues on that front, and they were quite thrilled with the idea that her and Marc would be able to attend the same college together. In different courses, sure, but in a somewhat embarrassing display, they were happy to know he and Chaney wouldn't have to deal with the logistics of attending different universities whilst they were dating.
"No, she and Sofia are doing a thing. Probably shopping," he answered, pausing his game so he could make eye contact. He might've been young, but he wasn't that rude. Not anymore at least.
Besides, Maria had a... way, of commanding attention. Mostly that, stepmother or not, he found her rather hot.
And after what Sofia had done to his brain, he sometimes imagined more taboo scenarios between him and Maria.
He did keep those in check though, even if he knew what she was. Especially because she was his dad's partner.
At the same time, he was confident Maria knew of everything he and Sofia got up to. Probably from the beginning, and Sofia had confirmed that, after she nearly killed that iced-up asshole, as much as Maria understood Sofia's regret, mama succubus made it damn clear she couldn't screw up like that again.
And since that night, he had grown comfortable with Sofia again, but he also saw her in a slightly different light. He understood just how dangerous she could be. But that was tempered by seeing how much it seemed to genuinely affect her.
It fuelled his fascination for her kind, it made her feel more alien in a way that drew him in. He was still going to go into the sciences, he was looking at astrophysics, or similar courses that might put him on a path to an aerospace career doing rocket science shit.
Maybe not the engineering side of things, but the studying space side of things.
He was definitely going to do some stuff on the side though, to learn more about the history of lust demons, though he'd have to keep it discrete. Mostly because looking up stuff about succubi would be weird enough, but he didn't want people thinking he was legit crazy because he believed they were real.
Maybe he was being paranoid.
"Well, if they're shopping, maybe Sofia can get me some milk," Maria said, looking in the fridge with a disappointed look. "Less than half a bottle."
"Her phone's never off, you can text her," Marc answered, returning his attention to his game.
"Ah, later, I'll let her spend time with Chaney," Maria conceded. Marc was certain Maria knew, if they weren't doing regular girl friends stuff, they were probably doing lewd shit.
"But what about you, anxious about going to uni?" she asked, shutting the fridge and walking over to the living room.
Truth be told, he was a little nervous, but he didn't really feel the dread. It was still months off before they were to even start.
"Nah, not really. Maybe when the time comes, but right now I'm pretty good," he admitted.
"Good to hear that," Maria agreed as she strolled behind the couch, idly watching Marc play his game. "But you know I'm always here to talk if you need it."
"I know, and thanks," he said, tilting his head up briefly to smile at her. He didn't think he could really call her 'mum', but besides the errant perverted thoughts, he did like and appreciate Maria. She was a good person, for a soul-sucking demon from hell. Or wherever it was they came from.
She smiled back before he returned to his game.
"But, speaking of being here..." she trailed off... and leaned down to rest her bust upon his head.
It made Marc freeze up, and get himself killed in his game.
"... we could do something else to pass the time~"
One of her hands drifted low, and Marc twitched when she began to knead his junk with exquisite ministrations.
He turned to face her, even with her generously endowed bust resting on his head.
"Uh... Maria?" he asked slowly, but she simply smirked.
"I know what you think about me. Your little fantasies. And you know what I am~ This shouldn't come as a surprise~"
She put a bit more pressure on his head with her bust, her hand kneading his crotch until she could fondle the growing bulge with fleeting touches, her other hand reaching down to grasp one of his thighs, and slowly bring it up his body until she was clutching his chest, gently bunching up his shirt.
Marc huffed, feeling heat spread across his face and arousal permeate his being.
"I mean... I don't..."
"Marc, my boy, you've always found me attractive... why deny yourself~?"
She gave his cock a firmer squeeze through his pants, and he groaned in arousal, laying the controller down on the cushion next to him, the game left idling.
"But... what about dad?" he asked, feeling embarrassed even mentioning it.
"Oh come now, you've been with Sofia how long? You should know by now that we don't work like that when it comes to our hearts. I love Peter, he is my Soul Mate... but you are equally compatible with me, and I just... cannot keep myself away from you~"
She sighed in seductive desire, and Marc wasn't exactly resisting her advances, starting to shift his hips as his erection strained against his pants, feeling his balls fondled through the material.
"You didn't encourage him on this trip just to get me al--"
