Help the demon

You glance briefly at the staff, hearing the librarian's plea. You even intend to get it, but not before taking another glance at the incredible show going on within the circle... Your eyes drift along her ruby-red skin, drinking in her devilish good looks. The more you look, the more jealous you get of the librarian. As your eyes drift over her large breasts, each adorned with a golden piercing, you feel your mouth water, and it's all you can do to stop yourself from drooling. As your eyes make their way down to the two enormous cocks, your mouth is no longer the only thing that's wet.

"Don't just stand there!" The blond shouts between loud moans. The librarian tries to pull away again, but the demoness grabs her by the hair and pulls her back onto the twin cocks in her ass and cunt, "That's right human," the scarlet-skinned devil purrs, her voice oozing with desire, "Don't just stand there, come on in. I promise I won't bite...unless you beg for it," she says with a sexy smirk.

What could go wrong? The demonness is contained within the circle, after all.

Pulling off the minimal clothes the school has provided you with, you step into the circle. Immediately, you can feel the hell-resident's power overcome you. She's definitely a succubus, no doubt about that, you can tell by the aura of overwhelming lust, and that wonderful scent. It's thick enough that if you stick out your tongue, you can taste it. It smells so good in here, you can't understand why the librarian would've wanted to leave.

You're broken out of your stupor by a loud moan coming from the librarian as the succubus finishes inside her, both her cocks pumping what must be a gallon of semen inside her, leaving the blonde a cum-soaked wreck. By her expression though, her tongue lolling out of her mouth and her eyes rolled back, she seems to have had an amazing time of it.

Now, the demonness turns to you, "Aaah, that was a nice start, but I'm not easily satisfied," she says, taking you by the chin and pulling her against you. Your tits rub together, and the piercings on her breasts feel almost electric against your nipples. "Now, be a good little witch and give your new mistress a titjob, won't you?" she says, running a hand through your hair, "If you do it, I'll make you feel so very good," she promises, her voice enticing. Motivated by the promise of pleasure, you drop to your knees, rubbing her two giant pricks between your breasts. You barely manage to fit them both between your tits, but with some determination, you make it happen.

The succubus moans with pleasure, and you fill with a sort of perverted pride knowing that you're making her feel good. "Mhmm, yes, now won't you be a good pet and suck my cocks? If you want to be naughty, I'll have to punish you..."
