"And that's how we calculate the area under these curves," Professor Malphas finished, pointing at his rather suggestive diagram on the board. "Remember, these principles apply to many aspects of seduction and pleasure."

I fought the urge to roll my eyes as the class erupted in giggles and appreciative murmurs. Basic calculus dressed up with erotic illustrations - hardly groundbreaking stuff.

"That was amazing!" Aria bounced in her seat next to me. "I finally understand integration! The way he explained it with those... visual aids."

"It's just elementary math with extra steps," I muttered under my breath, remembering the complex engineering calculations from my past life.

The bell rang, and we gathered our books. As we stepped into the hallway, Isabella materialized beside us, her silver hair catching the crimson light streaming through the windows.

"So," Isabella's ice-blue eyes sparkled with mischief. "Shall we settle our wager now, or do you have other commitments?"

My stomach did a flip. I'd hoped she might forget about the bet, but no such luck.

"I'm free!" Aria chirped, practically vibrating with excitement.

I opened my mouth to make an excuse, then closed it. Better to face this now than let it hang over my head.

"Let's... let's just get it over with," I managed, heat creeping up my neck.

"Excellent choice," Isabella purred, linking her arm through mine. "My room isn't far."

I let her lead us down the corridor, trying to ignore how my body trembled with both nervousness and anticipation. These demonic instincts were becoming harder to distinguish from my own desires - and that scared me more than anything else.

The crimson sun cast long shadows as Isabella led us away from the Academy's main building. My feet felt heavier with each step, but my body hummed with an electric anticipation I couldn't quite suppress.

"This way," Isabella gestured toward a separate stone structure adjacent to the Academy. The building's architecture matched the Academy's gothic style, but appeared newer, with sharper edges and more ornate decorations.

"Wait, why aren't we going to the dorms?" Aria's violet eyes darted between Isabella and the building.

Isabella's lips curled into a slight smile. "While the Academy provides dormitory accommodations, I opted for private quarters here." She brushed a strand of silver hair from her face. "I'd rather not share living space with other purebloods on a daily basis. They're absolutely insufferable with their constant posturing and politics."

The statement caught me off guard. "I thought the Academy didn't discriminate? Why do purebloods have separate dorms from regular succubi in the first place?"

"Politics, naturally." Isabella's ice-blue eyes hardened. "The Academy administration likely concluded that mixing purebloods and regular succubi in dorms would create unnecessary tension. So they implemented this segregation as a compromise." She unlocked an ornate door with a wave of her hand. "Most purebloods insisted on it, claiming they needed 'special accommodations' for their delicate sensibilities."

"Makes sense," Aria nodded, her purple eyes narrowing. "I couldn't imagine sharing living space with Valentina. The constant sneering would drive me insane within days."

Isabella guided us through several winding corridors before stopping at a black door adorned with silver runes. She pressed her palm against the centre, and the door swung open silently.

"Welcome to my humble abode," Isabella stepped inside. "I didn't want anything too extravagant. That would've drawn unnecessary attention."

I scanned the room. While larger than our dorm, it maintained a similar layout - a bed, desk, wardrobe, and sitting area. The main differences were the higher ceiling, and better quality furniture.

"The only downside of using personal funds for housing is that I had to acquire my own slave as well," Isabella said, gesturing toward the back of the room.

My eyes followed her motion. An orc stood quietly in the corner, his muscular frame impossible to miss. A thick collar encircled his neck, and silver rings pierced his nipples. The only clothing he wore was a loincloth that hung to his knees.

"So," Aria settled onto a plush armchair, her tone deliberately casual. "How are you finding Professor Malphas's teaching style? Those... interesting diagrams certainly made calculus more engaging."

"They certainly kept the class awake," Isabella replied, pouring blood-red drink into delicate cups. "Though I suspect some students were more focused on the illustrations than the actual mathematics."

"The equations were fairly straightforward," I added, accepting a cup. "Though the anatomical accuracy of the drawings was impressive."

"Speaking of impressive things," Isabella's ice-blue eyes fixed on me, her lips curving into a knowing smile. "I believe we have a certain wager to discuss."

I couldn't deny it any longer. My face burned hot as I stared into my cup, avoiding Isabella's piercing gaze. This felt worse than any other encounter I'd experienced since becoming a succubus. Those times had been driven by supernatural hunger - an external force I could blame. But now? I had initiated this myself. It felt more personal, which only amplified my embarrassment.

"What's there to discuss?" I managed to keep my voice steady despite the flutter in my chest.

Isabella's ice-blue eyes sparkled with amusement. "Many things." She took a deliberate sip from her cup. "After all, you won the bet, so you're the one who gets to choose."

"That's right," Aria chimed in, leaning forward in her chair with evident interest.

I gulped. My mind went blank. What was I supposed to choose? For once, my demonic instincts remained oddly silent, as if they were content to let me stew in my own embarrassment. The usual supernatural confidence that guided my actions had abandoned me, leaving me to flounder in this self-created situation.

I took a deep breath, letting my usual analytical mind take over. What was I so worried about? These were my friends. And this was Hell - being shy about intimacy made as much sense as being shy about breathing.

"You know what?" My voice came out stronger than expected. "Screw it."

Isabella's eyebrow arched. "Oh?"

I stood up, my supernatural grace taking over as I moved. In one fluid motion, I grabbed both of their hands and pulled them toward me.

"We're going to improvise." My fingers traced along Isabella's wrist, feeling her pulse quicken. "No planning. No overthinking."

Aria's violet eyes widened with delight. "Now this is the Lily I like to see."

I tugged them closer, letting my succubus nature guide my movements. Isabella's cool composure cracked just slightly - a subtle parting of her lips, a catch in her breath. Aria practically melted against me, her natural enthusiasm shining through.

"Both of you." I pulled them against me. "Right here."

Isabella's ice-blue eyes darkened. "Bold move, Nightstar."

"Scared?" I challenged, using her own family name pattern.

A flash of heat crossed her face. "You wish."

My hands found their waists, drawing them even closer. The familiar surge of supernatural confidence washed through me, drowning out any lingering doubts. This wasn't just about a bet anymore. This was about what I wanted.

I pulled Aria closer first, drawn to her familiar warmth. Our lips met with practiced ease - soft and welcoming. Her hand traced up my back as I deepened the kiss, tasting the sweetness that was uniquely Aria. When we parted, her violet eyes sparkled with joy.

Turning to Isabella, I found a different kind of anticipation. Her usual cool facade had slipped, revealing something raw underneath. Our kiss started tentative, exploring, before melting into something deeper. Where Aria was warm sunshine, Isabella was cool moonlight - both beautiful in their own ways.

We moved together, hands wandering with increasing boldness. Isabella's fingers traced patterns across my skin while Aria's lips found my neck. Each touch felt electric, sending shivers through my supernatural form.

As we continued exploring each other, something clicked in my mind. This wasn't just physical pleasure - it was deeper, more meaningful. The way we touched, the gentle caresses and soft sighs - this was intimacy on a different level.

I felt it in the way Isabella's usual barriers fell away, in how Aria's playfulness turned tender. This wasn't about feeding or satisfying urges. This was about showing complete trust in each other. Each touch, each kiss was a promise, an acceptance.

A pleasant warmth spread through my body as Isabella's cool fingers traced patterns down my spine. Aria's lips found my collarbone, her breath hot against my skin. My succubus instincts hummed in satisfaction, guiding my movements with supernatural grace. They recognized this ancient pattern even as my conscious mind was just beginning to realize it.

We helped each other undress, taking our time to appreciate every revealed inch. Isabella's pale skin contrasted beautifully with Aria's warmer tones. I found myself mesmerized by the differences - Isabella's lithe frame versus Aria's fuller curves.

If you come across this story on Amazon, be aware that it has been stolen from Royal Road. Please report it.

I gasped as Isabella's cool fingers reached between my thighs, teasing my intimacy. The sensation was delightfully different from Aria's warm touch on my breasts. My back arched involuntarily as pleasure coursed through me.

Following my instincts, I returned their touches with equal enthusiasm. My hands explored their bodies, discovering what made them sigh and moan. This felt nothing like my encounters with Arthur or Bellas. There was no hunger here, no need to feed. Instead, I felt a deep connection forming between us.

This was friendship expressed in the most succubus way possible - through intimacy without barriers or pretence.

"You're so beautiful," Aria whispered, her violet eyes full of genuine admiration as she traced the curve of my hip.

"Both of you are amazing," Isabella added, her usual coolness replaced by warm affection.

These weren't empty compliments meant to seduce. They were honest expressions of appreciation. Every touch, every kiss held meaning beyond mere physical pleasure.

We moved together in perfect harmony, sharing sensations that flowed between us like electricity. When Isabella's fingers curled inside me, I felt Aria shiver in response. When I kissed Aria deeply, Isabella moaned softly. We were connected on a level I hadn't experienced before.

Time seemed to lose meaning as we explored each other. My hands found all the places that made Isabella gasp, while Aria's clever tongue drew sounds from me I didn't know I could make. We took turns pleasuring each other, learning what each of us liked best.

The pleasure built gradually, like a symphony reaching its crescendo. When we finally peaked together, it wasn't just physical release - it was a moment of perfect unity. We collapsed onto Isabella's plush couch, our limbs pleasantly tangled.

But we were succubi. Our supernatural stamina meant this was just a pause, not an ending. Isabella's ice-blue eyes sparkled with mischief as she disentangled herself and walked to an ornate drawer.

"Since we're all warmed up," she said with a sultry smile, "perhaps you'd like to see my collection? I have some very interesting toys we could try."

I raised an eyebrow as she began pulling out various items, while Aria clapped her hands in delight.

I watched with growing curiosity as Isabella approached us, carrying what looked like flesh-colored implements in her hands. They weren't the plastic toys I'd expected - these seemed almost... alive.

Aria leaned forward, her eyes widening. "Those look so real!"

"They practically are." Isabella gave one a playful flick with her finger. The toy twitched in response. "Want to try it?"

"Yes!" Aria bounced excitedly.

My heart skipped a beat as both of them turned to look at me, their expressions reminding me of cats who'd spotted a particularly interesting mouse. Though their smiles were warm and playful, I found myself backing away slowly.

"Now wait just a minute-" I held up my hands defensively, trying to think of an excuse. But my mind went blank as they stalked closer, their grins widening.

"Don't be silly," Aria teased. "I can tell how much you want to try these."

To prove her point, she ran her tongue along one of the toys. "Mmm, it really does feel real. It even twitches!"

Isabella's ice-blue eyes sparkled with mischief. "You can have your turn with them later. For now..." She exchanged a look with Aria.

"After we've had our fun!" they declared in unison, pouncing toward me.

I yelped as they tackled me onto the plush couch, their laughter echoing through the room.

"You two are impossible," I complained without any real heat.

"You love us anyway," Aria grinned, pressing a kiss to my neck.

Isabella's cool fingers traced patterns on my thigh. "Besides, isn't this what best friends are for?"

I couldn't argue with that logic - not that I wanted to anymore.

"Fine," I sighed dramatically, trying to hide my smile. "Have your wicked way with me then."

"Oh, we plan to," Isabella purred.

Aria giggled. "This is going to be fun!"

They guided my hands to their breasts, and I followed my body's natural impulses, massaging the soft flesh. A shiver ran through me as I contemplated what they had planned.

"Your hands are so soft, Lily," Aria purred, her violet eyes half-lidded with pleasure. "They feel amazing."

Before I could respond, Isabella pushed me back onto the sofa, hovering above me with predatory grace. My breath caught in my throat as I felt something press against my entrance - Aria positioning one of those lifelike toys.

Isabella's ice-blue eyes locked with mine, a playful smile dancing across her lips. "I've wanted to do this since I first saw you." She captured my mouth in another deep kiss, our tongues dancing together as Aria slowly pushed the toy inside me.

I moaned into Isabella's mouth as the toy stretched me, the sensation sending waves of pleasure through my body. Isabella's cool skin provided a delicious contrast to the heat building within me, making every touch more intense.

"I wonder how it would feel to have one," Aria mused as she continued her movements, each thrust sending sparks of pleasure through me.

Isabella broke our kiss, a mischievous glint in her eyes. "We can try that later if you'd like." She brought the toy in her hand to her lips and gave it a long, slow lick before bringing it to my lips, clearly wanting to share.

I hesitated for a moment. As Liam, I never imagined being in this position. But I wasn't Liam anymore - I was a succubus, and I'd already crossed so many lines that my former self would have balked at. What was one more?

I extended my tongue, tasting the toy. Isabella's taste mixed with something else - slightly salty but not unpleasant. The sensation sparked something primal in my supernatural body, making me crave more.

Isabella's breath hitched as Aria's mouth found her most intimate place. She moved the toy away from our lips and pressed it between our hips, the pressure against my sensitive bud making me gasp.

Isabella shuddered above me, clearly feeling the same sensations. The toy seemed to pulse between us, responding to our movements like a living thing.

Aria's fingers traced patterns on my thigh as she continued her ministrations. The combined sensations of the toy inside me, the one pressed against my sensitive spot, and Isabella's cool skin against mine created a symphony of pleasure that made my head spin.

Our bodies moved together in perfect harmony, each touch and caress amplifying the others' pleasure. I could feel every shiver that ran through Isabella, every gasp that escaped Aria's lips. The connection between us grew stronger with each passing moment.

Isabella's usual composed demeanour had completely dissolved, replaced by raw passion. Her ice-blue eyes had darkened with desire, and soft moans escaped her lips with each movement. Aria's usual playfulness had transformed into focused intensity as she worked to bring us pleasure.

The toy inside me seemed to pulse with supernatural energy, matching the rhythm of our movements perfectly. Every thrust sent waves of pleasure through my body, building toward something greater than simple physical release.

The heat building inside me reached new heights as Isabella ground against me, the toy between us creating delicious friction. Aria's skilled movements with the other toy hit exactly the right spots, making me see stars.

I reached up to pull Isabella down for another kiss, tasting her moans as our pleasure built together. My other hand found Aria's thigh, squeezing gently in appreciation of her efforts.

Our supernatural stamina meant we could maintain this connection for hours, but the intensity of our shared pleasure was quickly becoming overwhelming. I could feel Isabella trembling above me, while Aria's movements grew more focused and deliberate.

The toys seemed to respond to our arousal, their movements becoming more pronounced. The one inside me hit spots I didn't even know existed, while the one pressed between Isabella and me seemed to pulse with its own rhythm.

I could still taste Isabella on my tongue as Aria's skilled movements drew increasingly desperate sounds from both of us. My body trembled with each expert touch, electricity racing through my nerves.

"My turn with her now," Aria announced, her violet eyes dark with desire.

Isabella released her hold on me but snatched the toy from Aria's hands. "Fine, but I'll be the one using this."

Before I could move, Aria straddled me, pinning me to the plush couch. "No running away tonight," she purred, her curves pressing against mine.

"Just relax." Aria's fingers traced patterns across my skin. "The night is still young." Her lips captured mine in a deep kiss that made my toes curl. Her hands roamed freely, finding all the spots that made me gasp and arch into her touch.

We moaned together as Isabella slipped the toys inside us both in one smooth motion. The initial stretch sent sparks of pleasure through my core.

"These have a special function," Isabella announced smugly from behind us. Suddenly, I felt the toy begin to move independently inside me, writhing and pulsing in ways that defied description. Aria's expression told me she felt the same incredible sensation.

"Oh gods," I gasped, my back arching off the couch. The toy seemed to know exactly where to press, how to move to drive me wild. Each twist and pulse sent waves of pleasure crashing through me.

"Someone really likes it," Isabella teased, her ice-blue eyes glinting with satisfaction.

"Just wait until it's your turn," I managed between moans. "We'll see how smug you are then."

The writhing sensation created an intense rhythm that had me seeing stars. Aria's weight on top of me, her breasts pressed against mine, only amplified every movement. Our bodies moved together instinctively, supernatural grace making each motion fluid and perfect.

Isabella's cool hands traced patterns on my heated skin, adding another layer to the overwhelming sensations. She knew exactly where to touch, how much pressure to apply to drive me closer to the edge.

Aria captured my mouth in another deep kiss, swallowing my increasingly desperate sounds. Her tongue danced with mine as the toys continued their relentless movements inside us both.

The pleasure built higher and higher, like a wave growing impossibly large. I could feel Aria trembling above me, her movements becoming erratic as she approached her peak. Isabella's skilled manipulation of the toys brought us closer and closer to release.

When it finally crashed over us, Aria and I reached our climax in perfect synchronization. The toy pulsed one final time before I felt warm liquid filling me. My eyes widened at the surprisingly realistic sensation.

"Impressed?" Isabella's voice dripped with satisfaction. "They're quite special, aren't they?"

Before I could respond, she withdrew the toys slowly, making both Aria and me shiver with aftershocks. But Isabella wasn't done - she had only just begun showing us her collection.

The next hours passed in a blur of pleasure as we traded positions and tried different toys from Isabella's extensive collection. Each one seemed designed to bring maximum pleasure in unique ways. Some vibrated, others pulsed, and a few did things I couldn't even describe.

I lost count of how many times we peaked together, our supernatural stamina allowing us to continue long past what would have exhausted mortals. Isabella proved to be as responsive as we were when it was her turn to be on the receiving end.

Aria's usual playfulness transformed into focused intensity as she worked to bring us pleasure, while Isabella's cool composure melted away completely under our combined attention.

We explored each other thoroughly, learning what made each of us gasp and moan. Isabella's ice-blue eyes would darken with desire whenever we found a particularly sensitive spot, while Aria's whole body would shiver when we hit just the right angle.

The toys enhanced our natural abilities, creating sensations that had us crying out in ecstasy. Some seemed to respond to our movements, adapting their rhythms to match our needs perfectly. Others created entirely new sensations that left us breathless and begging for more.

Time lost all meaning as we continued our exploration. Each peak seemed higher than the last, yet our supernatural nature meant we never tired. Instead, each climax just left us craving more, eager to try new combinations and positions.

I collapsed back against the silk sheets, panting heavily as another wave of pleasure subsided. Through half-lidded eyes, I saw Isabella glance at an ornate clock on her bedside table.

"We should probably stop," she said, her usual composure slightly dishevelled. "Classes start in two hours."

"Already?" Aria pouted, her violet eyes still dark with desire. "Time flies when you're having fun."

I sat up slowly, my body still tingling from our activities. "We need to clean up and change before anyone sees us."

Isabella slid off the bed with supernatural grace, gathering her scattered clothes. "You can use my private bath. It's through that door." She gestured to an archway carved with demonic runes.

"Dibs on first shower!" Aria bounced up, but Isabella caught her arm.

"It's big enough for all of us," Isabella smirked. "Unless you're suddenly shy?"

The bathroom proved as luxurious as the rest of Isabella's quarters. Black marble and gold fixtures gleamed in the crystal-powered lighting. Steam rose from a sunken tub large enough for ten people.

We helped each other wash away the evidence of our passionate night. Aria's fingers worked shampoo through my hair while Isabella's hands massaged soap across my back.

"We should do this again sometime," Aria suggested, helping me rinse my hair.

"Definitely," Isabella agreed. "Though perhaps with fewer toys next time." She winked at me. "Just us."

I felt my cheeks flush but nodded. What had started as stupid bet had evolved into something deeper - a strengthening of our friendship through shared intimacy.

We dried off and dressed quickly, knowing other students would soon fill the academy halls. Isabella summoned her slave to change her sheets while we gathered our things.

"See you in class," Isabella said, pressing a light kiss to my cheek before doing the same to Aria.

We slipped out of her private quarters just as Igneus crystal dome begun glowing with dawn's red light. My body felt pleasantly relaxed despite the lack of sleep, and I couldn't keep a small smile off my face as we headed back to our room to change for classes.
