The interior of the carriage had become a literal pressure cooker of Aether. The windows were fogged with a thick, sweet-smelling steam—the physical result of Lyra's wind and Caelum's gold heating Vespera's ice until it turned into vapor.
Vespera was no longer the stern Professor. She knelt on the plush carpet between Caelum's legs, her indigo robes pulled open at the shoulders. Her breathing was ragged, her chest glistening with a fine sheen of sweat that caught the golden light radiating from Caelum.
"I... I have studied Aether for twenty years," Vespera panted, her hands clutching Caelum's knees for balance. "But this... this is like drinking liquid sun. My core... it's melting."
Caelum looked down at her, then shifted his gaze to Lyra. The village girl was already halfway out of her thin tunic, her skin flushed a deep, beautiful pink. She was sitting behind Caelum, her arms wrapped tightly around his neck, her soft, bare breasts pressing firmly against his back.
"Don't just watch, Lyra," Caelum commanded softly. "Help the Professor find her balance."
Lyra leaned forward, her teal energy flowing like a river. She reached around Caelum and placed her small, warm hands over Vespera's, locking them all together in a physical and energetic circuit.
The "Triple Distillation" began. Caelum acted as the pump, sending a heavy, throb of golden Aether through Lyra. Lyra's wind refined the energy, making it light and tingly, and then it slammed into Vespera.
Vespera's back arched, her mouth falling open in a silent scream of pure, biological ecstasy. The indigo energy inside her, which had been frozen and rigid for years, finally shattered. It wasn't just a sexual release; it was a magical breakthrough. Her power level was rising, fueled by the "trash" energy she was burning off and the "pure" gold she was taking in from Caelum.
"Caelum, please..." Vespera whimpered, her dignified persona completely gone. She looked up at him with eyes clouded by lust and devotion. "I need... the source. I need to take it all."
Caelum didn't make her wait. He pulled Vespera up, her silk stockings sliding against the velvet seat, and brought her into the heat of the center. Lyra moved as well, her body slick and hungry, pressing against Caelum's side.
The carriage was no longer just a vehicle; it was a sanctuary of skin and light. Caelum moved with a calm, logical precision, ensuring that every touch and every thrust served a purpose—to maximize the resonance between the three of them.
Every time he entered one of them, a pulse of gold light exploded in the carriage, making the fog on the windows glow. Lyra's voice was high and melodic, a constant song of pleasure, while Vespera's was a deep, sophisticated moan that shook the air.
As the final "Reaction" hit, the three of them were blinded by a flash of white-gold light. Vespera collapsed against Caelum's chest, her indigo Aether now swirling with beautiful golden flecks. Lyra lay draped over his lap, her teal energy soft and satisfied.
Caelum leaned back, his golden eyes glowing brighter than ever. He felt stronger, faster, and more alive. He hadn't just enjoyed two beautiful women; he had upgraded his own soul and theirs.
"Is the lesson... over... Professor?" Caelum whispered into Vespera's ear.
Vespera couldn't even speak. She simply nodded, her head resting on his shoulder, her heart beating in perfect time with his. She knew that when they walked out of this carriage and into the Academy, she would never be able to look at him as just a student ever again. He was her master, her catalyst, and her greatest discovery.
