The bell for recess rang and the demons sauntered out of class, looking sneaky no matter how hard they tried not to. Jake had Alex hang out with other people while he and Anna searched for a place they could have fun. They ended up using their magic to teleport to Jake's bedroom. Once there they met in a kiss and were soon making out with intense passion and lust, all typical of lilitus. As they did so Anna unzipped Jake's vest and threw it off, and feeling every single one of his toned, solid muscles. Her slim hands worked across his pecs, his solid six-pack abs, his biceps, and the muscles on his back. Then she pulled off his booty shorts and grabbed his firm, round ass.
Jake grinned seductively and pulled back for a moment. "You're a girl who likes quality," he said, "But guess what? I'm more than just a normal incubus."
"I'll say," Anna replied, gazing at his thong and the noticeable bulge within.
"Not exactly what I meant. You know how we lilitus can change our appearances to make ourselves appealing to others? Well I can do an extended version of that on others."
To punctuate his point he caused Anna's budding breasts to expand, filling out her corset. They grew to A-cup, then B, then C and finally stopped at D-Cup, but sized to fit her body as well. "Mmm, well why didn't you mention this to start?" asked the succubus, feeling her newly enlarged breasts for a moment.
"I do good work," said Jake, gazing almost hungrily at her impressive cleavage, caused by her breasts practically spilling out the top of her corset. "And there's more."
Although Anna already possessed some curves, namely a smooth, round, heart-shaped ass and somewhat wide hips, Jake increased these attributes further, expanding her rear until it was as large as it could be without losing its perfection. He made her hips grow wider too, making her hourglass figure much more obvious. "So nice," moaned Anna as she ran her hands over her newly enhanced figure. "You know sexy, I think you could afford to be sexier," she suggested, pushing up close to him and kissing him.
"I think you're right," said Jake.
He increased his muscle a little, not so that he became bulky, but enough that it was fairly noticeable. He was still lean though, but with a little extra size, both in muscle and a couple inches in height. Anna, already drooling as much over him as he was over her was looking even more impressed as she felt his larger pecs and solid abs. He increased his own ass too, making it a bit larger, and rounder, and maintaining its muscular firmness. Finally the aspect that was most interesting Anna was the bulge in Jake's thong, which grew even larger. The two demons stood about five foot even, rather tall for ten year olds, with the incubus being as buff as a miniature pro-athlete and as large as a miniature porn star, while the succubus was like a miniature supermodel crossed with a porn star. But their pale skin, their demonic features, and the twisted, seductive expressions on their youthful faces made the sight almost more creepy than sexy.
"Now that's sexy," Anna purred, bringing her barbed tail whipping across Jake's bare back.
Jake grunted in pleasure as the pain of the barbs sank into his back. Soon he was kissing her again, and undoing her corset, throwing the garment off and leaving the succubus shirtless while he felt up her naked torso. He brought his tail whipping into her and she moaned in pleasure too. Then he pulled off her skirt and it left the two demons in nothing but a thong each. The one interesting thing with lilitus, though, is they're equal. And as the two of them rolled around in their erotic fun, it was obvious that neither was superior to the other. Each delivered equal amount of whipping, and as they threw off their thongs and began pushing into sex, they both took turns on top. Both horny demons who existed for sex, doing what they did best.
