In the dark of the night, as the clock ticked towards three in the morning, the hour that tries... well, some people's souls, three junior-level students at the Highpoint Academy of the Supernatural were attempting a post-graduate level summoning spell.
Ordinarily, most such students would have been doing anything else other than trying to read ahead, but this particular spell had been attempted before, by many such students, for a very obvious reason. Because if there's one thing that can motivate some college students to do difficult, complex supernatural calculus and contract magic, it's hormones.

"Yeah, I double checked the array come on, what do you take me for?" Agata, the short, burly and curvy dwarf girl with black hair said, closing the last of the technically restricted heavy summoning tomes currently resting on a cheap plywood desk in the cramped dorm.
Lena, her tall, waifish, dark skinned wood elf roommate, glared at her, tweaking a line of salt in the complex ring and knot diagram laid our over the cleared floor of their dorm. "Because last time you said you checked, we summoned a bunch of demon cockroaches and lost ten grade points." she answered, standing to her full height and looming over the four-two dwarf girl.
"If you two don't stop with the homoerotic tsundere dance and get casting," the elf and dwarf girls glared at their third companion, saying 'ew' in concert, "none of us are gonna get any tonight." she finished, undaunted. She in question was Sally, a five-foot human girl with generous curves and blonde hair, and a smug demeanor even when frowning at her classmates.
"Homoerotic?" Agata asked, incredulous.
"Tsundere?" Lena asked, glaring.
"We aren't gay!" they both said simultaneously.
"Fuckit." Sally said stomping past and whipping out her smartphone, wrapped in an Elfwood and silver caster case to conduct magic into and out of the magitech device.
She prodded at the screen. "Array locked. Incubus designated, set to quasirandom, mid-scale. We are the offering, so to speak. Anyone got the..."
Lena pulled out a sheet of copier paper with dense writing on it.
"...contract. Cool." Sally finished.
"Get in position, lets do this." she said.
The other two scurried into position at equidistant points on the circle.
"Wait, incubus summoning." Agata said. "Clothes."
"Oh, right duh." the other two said, hurriedly doffing their pajamas, consisting entirely of their panties and a t-shirt, and in Agata's case, a bathrobe on top.
Naked as the day they were born, the three returned to position. Agata was... marginally trimmed, bushy between the legs. Lena was entirely shaved and apparently waxed, judging from the faint redness still present, leaving her brown-green hair only on her head, revealing a small, and now hard penis. And Sally had shaved.
"Time to summon us an incubus." Sally said.
They stood at three points in the circle, Sally placed her phone at a particular point on the circle, the other two following suit, though Lena's was a slick-looking flip phone and Agata's was bulked up with a rough 3d-printed casing instead of whatever it had had originally.
They began chanting, their phones began playing a complex animated image to go along with the magically charged math they were doing, and the salt line began to glow.
Lighting and wind surged in the middle of the diagram, and then suddenly, it was silent and dark as the magic stopped, and the lights went out with a pop.
"Ah come on!" Agata shouted. "This is the
third
time
this week
the damn building has lost power after a spell."
"Everyone hold still." Lena snapped. Agata had been trying to reach for her phone, but she froze at Lena's sudden sharp tone. When she got quiet like that, that meant trouble.
Sally snapped her fingers. Her phone lit back up, bathing the room in a cool light, and revealing a dark figure in the middle of the circle.
"Why hello there." said a voice. It wasn't quite what any of them expected, a smoky contralto with a strange accent.
"Uh, hi?"Agata said.
The lights flickered back on.
"Um, Agata, does this
look
like you got the spell right?"

The demon in question was taller than all three of them, and, in the dim light from their phones, visibly, and unmistakably female.
"Agata, why is the summon a girl?" Lena asked quietly.
"I'm sure I got the summon right!" Agata said, plaintively.
"Well you must have fucked
something
up!" Lena hissed.
Sally sighed. "Not the time, you two." she said, and turned to face the demoness, trying to remember how to cancel a summons.
The lights clicked back on, to reveal the demoness in her full glory. Six foot two, deep maroon skin, with subtle scales, a long, spade-tipped tail and generous curves, she observed the three with an amused demeanor, her glowing gold eyes scanning up and down the three students' bodies with a hungry look.
She had horns. Long, curved horns that jutted straight out of her forehead before arching up and back in sweeping curves that stuck back over the top of her head and her long, straight mane of black, lustrous hair.
Her bare pussy had a neatly trimmed pattern of black bush around it.
Sally focused on her mage sight, only to be half-blinded by the sheer force of the creature's power.
"Fuck, girls, we need to cancel it, now!" she called out.
"Oh my, no. it's far too late for that, dears." the demoness said, her voice giving Sally butterflies in her stomach and setting her pussy to tingling a little.
The other two finally glanced back, only to see the demoness suddenly pulse, a wave of something like a heat haze washing off of her and causing the still faintly glowing circle to wink out.
The same wave washed over them, heating the air in the room until sweat burst out of the three young women's skin, and carrying with it a smell that was like the combination of cinnamon and a gym shower after the girls' team had a long, arduous practice.
It sent a frisson of heat through all three of them.
She stepped forwards, looming over the Elf and Dwarf girls who had been arguing.
"We uh, we were trying to summon an incubus?" Lena squeaked.
"And you succeeded, dear." the demoness said. "And now you must present the contract." she said.
