"...a cowboy robot", Jeff announced as he hit the enter key, "You might want to strip though, I don't know if your clothes can handle this."
Confused by the strange prospect Dean stripped naked, waiting for any changes to appear. Immediately the reason for stripping became apparent, as the first wave of changes bulked him up considerably making him look somewhat more muscular while seemingly retreating his body hair, leaving him completely bald and smooth.
At his feet the second wave of changes started to happen. At first his toes started to merge together into one solid block, then the sole of his feet started to turn black and formed a thick layer which bent upwards where the toes were, giving them a wide trapezoid. At the back of the feet it was turning into a heel and along its length a pattern started to form. The rest of his feet started to become even smoother up to the point of being shiny, it also changed to a reddish brown up to his knees. Then its surface widened to a cone, leaving a core inside.
At the changes progressed upwards Deans thighs started to change too, taking on a similar shiny finish, but in a bright blue tone. At his knees joints formed sturdy, but also protected by the boots. On the inside and the outside a set of vents started to appear. Dean was petrified as the changes reached his already erect member which also turned into a bright red stack of cylinders apparently telescopic. He tried to touch it, which immediately sent a strong wave of pleasure through his body. Like in trance he continued rubbing his shaft.
Unnoticed in his bliss the changes started to spread upwards, turning his torso blue and shiny. On his front large sturdy plates appeared in a roughly triangular form, sculpting out stylized versions of pecs. Below it, mostly visible at his sides, black shingles appeared giving both flexibility and protection. On his back 2 brown strips started to grow around his body. As they joined at the front a thick rectangular belt buckle appeared with a red window inside of it. It became stuck to the lower angle of the triangles. From there the strips grew downwards to his right leg forming a holster for a gun, as well as the gun itself.
Then his arms started to change, at first his shoulders grew in side as if he was wearing massive shoulder pads. Then his arms became equally shiny and joints formed at his elbow, his wrists and even his individual fingers. His finger-pads turned black and also got a structure, though much finer than what he had on his boots. They turned brown and into a similar shape as his boots were.
The only thing that was left was his head. Dean had a goofy grin full of bliss from the constant pleasure he was getting from his new body. Quickly his neck turned black, then his mouth seized up forming a block. His early also merged with the rest of his body leaving a bold scalp. His scalp turned blue and a rim started to push outwards, forming something like a hat. As it finishes it pulls upwards, mimicking the style of some cowboy hats. The last part to go were his eyes, which filled up with the rest and turned into a red visor covering the space where both eyes were.
Dean now was a full robot he couldn't experience much of it as his systems were about to shutdown. quickly his new telescopic member retracted and a hatch closed over it, then everything went black.
