Thalya glanced at each one of the containers and their labels, she really didn't want to drink from any of them, she knew that they would somehow make her condition far worse than now, but she had no choice.
There was nothing that could change her back, there was a keg labeled "Succubi's gift" , but she would be a beast rather than a demon, even if it would've given her more magical knowledge than now. Thalya glanced over to a keg labeled "Stallion's pride" , shaking her head as she headed closer to it.
She gently positioned a small empty vial under the handle of the keg, before pulling the lever, a velvet liquid pouring out as it filled up most of the vial.
She let out a deep sigh before gently taking a sip, coughing a little as the taste of the substance mixed up with the musky scent, she laid there for a few seconds, waiting to see if something would happen, it seemed like it didn't affect her in any way, perhaps she could take another sip...
"Aaaah!" moaned Thalya all of a sudden, as she doubled over, a large amount of heat gathered within her body, forcing her to take off her robe.
She stood there paralyzed as her cock throbbed and grew, shaping itself into the mottled dick of a proud stallion, her breasts shrunk, before melting in her body due to the growing muscles, snapping her bra open, leaving her fully naked. Her hair, which used to be shoulder length grew, reaching her back and seemingly becoming shinier.
Thalya let out multiple pants as the changes stopped, she or rather, he, looked at his body, his breasts were gone, his phallus and testicles were now ones of a horse. He clearly was not a female anymore.
Thalya felt like she was on the verge of crying, a tear streamed down his eye, rolling down his still feminine cheeks and face. Maybe... maybe he and Lyra shouldn't have went into this dungeon.
He took a final deep breath, shaking his head multiple times, "Lyra, I will find you and save you from these monsters. And together, we shall take the boon from this place." he said, with a still feminine yet determined voice.
Thalya picked up his robe, still suprised it somehow fitted him, although it did little to cover up his erection, before making his way towards the door to the next room, it almost seemed like he grew a little during his change.
A thought passed through his mind, maybe... maybe he could use these substances for a good cause, to make himself more stronger, despite shedding his humanity away in the process, he thought that maybe, there would be some way, after he and Lyra left the dungeon to change back into humans. With a deep breath, he picked up two small empty vials from within his robe, used to gather small sources of liquids for research, before carefully filling them both with the "Stallion's pride" and the "Dragon's heart" , one for himself and one for his beloved apprentice.
Another thought crossed his mind, as he saw small droplets leak out from the handle of the "Stallion's Pride" keg, should he just drink more of it? It would surely make him faster and stronger, not needing sleep or rest to continue his search, despite possibly completely transforming him into something else.
