It didn't take long for Thalya to sigh, his lust was too much, he tried to fight it off countless times, restraining himself from making the changes rip away his humanity, thinking that it would be a disadvantage and that he would turn into a feral creature.
And yet here was his apprentice, transformed into a beautiful hermaphrodite dragon, shi didn't seem to mind the face shi was no longer human, infact, shi seemed to be enjoying it.
"Well?" asked Lyra, breaking the awkward silence between the two, Thalya took a deep breath before finally making his decision.
Without saying anything, he laid near a wall and carefully undid his robe, shuddering a little as he felt a cold breeze against his privates, Thalya closed his eyes and gently started stroking his stallion phallus.
He shuddered as he felt the soft skin of his hands rub againt his organ, he hated to admit it, but it felt so good, he quickly picked up the pace as black fur started growing all around his body and ears changed into the ones of a horse.
Lyra meanwhile watched, hir draconic dicks peaking out of their slits as shi watched hir teacher pleasure himself, his feminine pants and moans gradually changing into masculine huffs and whinnies, reminiscent of a horse.
Thalya's shoes bursted open, revealing how his feet changed into hooves, with each heartbeat, his muscles grew, eventually ripping open his robe, revealing his tough figure.
The changes reached his face, Thalya at first had a look of denial while he started stroking himself, but as he felt the satisfaction and relief, his face perfectly reflected his current ecstasy, the bones of his face pushed out, turning it into the snout of a horse.
"YEEESSSS!!!!" Shouted Thalya all of a sudden, his voice incredibly masculine, letting out a loud whiny as his dick shot equine seed around the room, his apprentice barely managing to evade it all.
After that climax, Thalya quickly fell asleep, due to his exhaustion, Lyra let out a childish giggle as shi huddled close to hie teacher, letting out a quiet laugh as shi fely his mane rub against hir snout, before falling asleep as well.
