"You've reached the saturation point," Caelum finally whispered.
He didn't move her to the desk. He stood her up, turning her around and slamming her chest-first against the heavy oak bookshelves. The jars of ingredients rattled as he hiked her indigo robes up to her waist, revealing her **milky, wide backside** and the **deep, wet crevice** that was practically weeping for him.
He rewarded her with a single, devastating thrust.
Vespera let out a sound that wasn't human—a raw, guttural wail of absolute release. The penetration was deep, hitting her overtaxed core with the force of a tidal wave. Caelum didn't hold back; he used his **Gold Aether** to vibrate her internal walls, creating a friction that felt like liquid fire.
The encounter was a masterclass in carnal science. Caelum's hands were everywhere, kneading her **heavy, swaying breasts** and digging into the **soft, abundant flesh of her hips**. Vespera's **buttocks clapped loudly** against his pelvis, the sound mixing with the wet, squelching friction of their union.
She was shivering, her entire frame caught in a continuous, high-frequency tremor. Every thrust sent a new wave of indigo light through the room as her magic gave in to his pleasure. She was no longer a Professor; she was a **vessel**, being filled and reshaped by his golden will.
"Caelum! I'm melting! I'm yours!" she cried out, her head thumping against the books.
The climax was a total system failure. Caelum gripped her waist, his thumbs bruising her skin as he delivered a final, pressurized surge of Gold Aether. Vespera's body went rigid, her **eyes rolling back** as she experienced a soul-shattering orgasm that lasted for nearly a minute. Her **indigo Aether flooded the room**, turning the air itself into a thick, intoxicating violet haze.
She collapsed into his arms, a **shattered, saturated mess** of silk and spent magic. Caelum looked down at his work, the three women in the room now completely bonded to his frequency.
"The experiment," Caelum murmured, looking at the unconscious Vespera, "is a resounding success."
