Joe began to pant violently, lurching back and forth on all fours as he became possessed by an inhuman desire - a burning passion originating from satyr-dom. The Human was not a creature adapted for such desire, the pleasure that could satisfy gods and split humans in two, but soon that would change.
Joe kicked away his bathers, groaning with relief as his form was released now naked and free. His mind welcomed the nudity, for it was just as nature intended. It felt perfect and all together good. Now spread across the wet tiles on his side, Joe was gripped his cock and began pounding away at it wildly, untamed and unabashedly unashamed. His chest heaved and hoed as he rode the high of brilliant, magically induced, pleasurer - it was a physicals sensation unlike anything Joe had felt in his simple, human life. How how the lust burned him!
Adam simply admired the display from the comfort of his spa. What luck to watch a new brother be born into existence, and how envious was he to see the man welcomed into the pleasures of satyr love.

Adam giggled and watched Joe's hairy legs grow shagger and shaggier by the second, slowly until it couldn't be anything other than fur. Then at once with a loud snap, his legs changed into that which resembled goats. His feet rapidly twisted and curled into hoofs.
With one last wail, the last inches of humanity vanishing from his form, as his cock sprung to twelve glorious inches! It was goatish, inhuman and now fired an endless load of cum as the new Satyr Joe fell to the spa floor a changed man.
Adam hopped on out of his spa and then approached the new, unconscious satyr and...
