The summoning circles filled up a good portion of Star Tracker's bedroom floor. Candles lined the chalk inscriptions. And, in the center, lay the tribute required for the ritual.
A textbook on Advanced Arcane Theory.
(He'd been careful to get a first edition. The spell had been very specific about that.)
On his knees in front of the circle, Star Tracker closed his eyes, activated his horn, and laid his hands on the circle.
"I hope this works," he prayed. Someone had told him how to do it on an online forum, but they'd been an earth pony. He wasn't sure how earth ponies did magic.
A flash of light shone through his eyelids, then subsided. He popped them open and his heart backflipped inside his chest.
He gazed upon well-formed hooves that tapered up into the ankle, then the knee, leading into nice, round thighs, and capped by child-bearing hips. The waist tapered back in and led into breasts that were barely contained by the slick leather corset that sleeved her purple body. As his gaze skimmed up, he took note of the wings flexing behind her, the smooth muscles punctuated with skeletal supports.
Her face was a different matter entirely.
The structure suggested youth, if not purity, framed by violet hair with a stripe of hot pink. Upon her head was the curved horn of a unicorn—much like his—which was flanked by spiraled ram's horns.
He had done it. He had summoned a succubus!
A realization that was only further confirmed when she used the spade-end of her long, wiry tail to close his mouth. She then leaned down and offered a hand, which provided him with a perfect view of her luscious cleavage.
"Hi," she said as she grasped his hand and helped him to his feet, "I'm Twilight Sparkle, and I'll be attending to you for the next, uh…"
Star Tracker's brain hit a loose cog. He wasn't expecting succubi to be cordial.
She looked behind her and took note of the runes, then pulled out a tablet computer and poked at it. "The… next… let's see, kink at ten o'clock, spiral at six-thirty…" Twilight looked up into Star Tracker's eyes. "Fifteen minutes!" She pursed her lips and looked around, then tickled the tablet a bit more. "Or whenever you decide to end the session."
Star Tracker blinked. "F-fifteen minutes?" He shook his head. "Wh-what do you mean fifteen minutes?"
A smile pierced her cheeks as she presented the tablet to the poor young stallion. "It's all right here in the terms and agreements."
"Terms and agreements…" he trailed off as he sat back on his bed and carefully dragged his finger up. He was perusing through the legal language when he felt the warmth of flesh next to him. Star Tracker looked over to see the succubus looking over his shoulder, biting her lip. He gave her a "what are you doing you're all up in my grill" look. But, you know, kindly, because she was a guest.
A small bit of saliva escaped from the corner of Twilight's mouth as she put her hand on his thigh. "Keep scrolling, you're almost at the best part."
"Mhm." He supposed the female attention was nice. "Okay, so, it says that the time doesn't start until I sign."
"Uh-huh," she purred.
Star Tracker nodded, scrolled to the end, then set the tablet down. "So, uh, it says you have an app?"
Twilight breathed in, then out, then snapped to attention. "Oh, uh, yeah! We have a phone app that you can download, so you can save money on chalk and candles!" She grasped the tablet in the glow of her magic and swiped several times. "Here, just scan this QR code with your phone."
Star Tracker grabbed his phone from the end table and did as Twilight said, then put his phone back.
"Okay, uh, I guess bring up the signature page again."
"So, what do you do?" Twilight asked as she brought up the signature page.
"I, uh, work in food service," he said as he wiggled his finger across the tablet and confirmed.
Twilight nodded and put the tablet away. "I've heard that's rough, I don't envy you." She slitted her eyes and moved the corners of her mouth upwards. "If you work with food, I suggest you pick up Pinkie Pie's Perfect Party Pastries for some at home fun with cooking."
Star Tracker bit his lip and blushed. "I uh…
I… uh…"
She put a hand to his cheek and unzipped his pants with the other, his half swollen member unfurling itself. "It's okay," Twilight said as she coiled her tail around his penis, stroking it slow and smoothly akin to a silken hand.
Star Tracker gritted his teeth, and the blood in his brain flowed to his dick as it reached full mast, as well as full sensitivity. "I-I really admire your articles on friendship harmonics."
Twilight nodded and picked up the pace, Star Tracker gripping the comforter in response. "Oh, yes, I put a lot of research into adjusting verbal and body language to establish camaraderie." Her tail-coil twisted as it slithered along his shaft, causing his eyes to roll a bit.
"And I...and I—ooh!"
"Just stimulating your prostate with my magic to maximize ejaculation volume."
He looked up to see her central horn glowing. "Oh, okay. An-Anyway. I found your," he grunted and grit his teeth as the multiple points of stimulation overwhelmed his senses. "I liked your dissertation on relationship harmonics!"
"Yeah, I found that an interesting paper to write, you know, trying to zero in on how people could be the best they can be for one another."
Star Tracker took deep breaths as he could feel his stack about to blow. "I bet most people just look at your big boobs, but all I can see is that big sexy brain!"
Twilight blushed a bit and put a hand to her lips. "That's very flattering of you to say." Her tail was rotating and sliding like some kind of big sexy silky machine designed to make him cum.
"I really wanna fuck your brain!" Star Tracker shouted as a decent shot of semen shot out of his cock and fell onto his thigh. He took deep breaths at Twilight's tail uncoiled and she scooped the glob of vitality off of him.
"I can say I've never heard that before," Twilight snickered as she licked the cum off of her tail.
He scratched the back of his head as his cheeks turned a deep crimson. "Sorry, I just get in the moment and say weird things."
Twilight stood up. "No, it's okay. If there's anything I've learned in my studies, it's what makes us different is what makes us special." She levitated the tablet over to her. "Now my favorite part!"
The smile that appeared was not unlike one a serial killer would give. Star Tracker's breath hitched.
"A-and what would that be?"
He brow furrowed as she retained her smile. "The checklist!"
Star Tracker's entire body relaxed as she muttered to herself.
"Okay... Introduce… legal… app promotion… small talk… advertisement… sexual activity…" Twilight pursed her lips. "Just one more thing." She waved at her client. "Enjoy your day!"
Star Tracker waved as she disappeared as she appeared, his arm reflexively raising to shield his eyes from the flash of light.
He reflected on his good fortune when he found out that Twilight Sparkle was a succubus and he could have some alone time with her. He wished he could do it again.
Speaking of…
He grabbed his phone off of the end table and excitedly downloaded the app. An eyebrow raised in confusion.
"...why does it need permission to send and receive calls?"
