The curse of a good pussy

"Drained him, after one orgasm?"

Mitzit giggled before making herself comfortable on the chair nearby.

"Not quite."

She sat up and watched Roy with a concerned look.

"He's fine, don't worry. Luckily he pulled out before you took too much, or I would have had to pull you two away."

Nihja gave a puzzled look, getting comfortable herself with her legs spread slightly.

"I call it a curse we have. You're still learning so I'll try to explain it to the best of my knowledge. We're succubi, right? Lesser succubi to be exact, but like any sex demon we require a... shall we say unique source of food?"

"You mean, cum?" She asked, fingering her used pussy and raising up two fingers with Roy's seed coating them as an example.

Mitzi chuckled and pulled her hand to her, suckling those fingers dry.

Gulp!

"Mm! Not quite hehe, cum does help but what we need exactly is their sexual essence. You know how I caught you by scent, yes? Our sense of smell detects sexual hormones, we can tell if someone is having sex for miles away. Pretty kinky hehe, and probably one reason as to why we're always... eh..."

"Horny."

"Yea, that. Sorry, just never thought my baby sis would be hearing this from me." She giggled lightly, sneaking a glance down below before making eye contact. "There's more to that, but that's like a different topic entirely. Basically, we feed off of sexual energy that comes out from their soul. You know how people can cum a big load? That's when their essence is at the surface in its peak, and a good orgasm from us allows us to drain that from them and sort of feed ourselves in that way. Keeps us young and beautiful, so perks." She smiled proudly at that, her eyes darting a second time before shaking her head. Even her mouth began to salivate.

"But yea, too much of a good thing never ends well. Cumming feels good, but too many orgasms will become painful. Same with feeding, it enhances the feeling for you both but you need to control how much you take. Too much of it and well..." They both glanced over at the sleeping Roy beneath them.

"So what, we're like demonic prostitutes?"

Both girls paused before bursting out in sudden laughter, chuckling and giggling at the silly comparison. It was nice to sort of break the tension and lighten up the mood for the two.

"Yea, sort of I suppose." She replied, licking her lips.

This time Nihja giggled and parted her legs further.

"Okay then teacher, is that it for my lesson? You gonna teach me more about succubus anatomy or are you going to keep staring?"

Mitzi blinked before looking away, covering her eyes. "Sorry! Just... it looks... ughh I don't know,"

"You want a taste?"

She blinked and looked over to see Nihja parting her lips. It was an erotic sight, Roy's cum was seeping out of her pussy and dripping down her thighs, a few drops landing onto the floor. She couldn't help but giggle to herself watching Mitzi stare with an open mouth, like a lost soul in a desert staring at a pool of fresh water.

Her answer was confirmed as her skin changed from flesh to pale gray and her demon eyes resurfaced in it's blood red natural color. Her tongue was much longer and more slender, her tail slipped out from her dress, and she was hungry.

"If you don't mind, yea I'd like that."

Nihja beamed proudly as Mitzi scooted forward between her legs. Looks like she was right about having a curse, a curse so strong even other sex demons succumb to it.

The curse of a good pussy.
