Adam grabbed the horse fur and stuffed it in the elixir. He waited impatiently and once the potion turned deep purple he grabs and drinks it all without hesitation. Adam stands, awaiting his change. Suddenly, a tingling sensation fills his body. "Yes! It's finally happening!" he exclaims. Adam looks down and sees the outline of his cock and balls pressing against his pants. The seems of his pants rip and shred as his big meaty cock flops out.
Adam instantly grabs his cock and moans loudly. He takes off his pants and underwear and watches as his balls enlarged and hang low. Adam huffs as his cock becomes uncomfortably erect, he starts masturbating aggressively. He starts to notice more changes in his dick, the tip slowly becomes flat and rigid, his forskin retracts to the center of his shaft and forms a ring, the flesh of both his cock and balls turn black. Before he can process the sudden changes to his manhood, Adam gives one involuntary thrust into the air and cum so hards his horse balls vibrate. He covers the floor in his seed and falls on all fours, panting heavy. Adam looks down at his new horse cock and smiles, but was this all he wanted from the elixir he created?
Some still remains in the bottle on his desk.
