Matt dutifully responded "Yes sir!", after all that was what he was made for. He was a powered armored suit and it was his duty to protect and serve his wearer even though it was unclear what that meant if his wearer was a being made out of electricity like Jacob.
"Good", Jacob said, "now bend over". Matt did so, getting down on all fours. He certainly wasn't meant to be entered from behind, but this was not going to be normal in any case. Jacob went to face his bum, arcing into Matt from his crotch, stimulating his electronics in ways they were not meant to be stimulated, causing a form of electronic orgasm rising and rising in tension before, Matt became paralyzed from the overload.
Jacob dissolved into a flash of light and entered Matt's electronic mind. Matt was way more interesting than his computer. He could easily read all his memories, his tastes, his ideas.... and even change them to his will. He could also see the abilities of his robotic body. Not only could he interface with his wearer to follow its movements, he also had a special camouflage function allowing Matt to change his shape. This intrigued him so he looked into it. It seemed to be a cut down version of the Chronivac, allowing himself to change in many ways. If the wearer wouldn't fit the form, it could simply be digitized for the time being.
Jacob decided to try it out and designed one set of camouflage and released Matt's mind from its stasis. "I've designed you a camouflage", Jacob said as he was walking Matt over to the nearest full-sided mirror, "put it on." "Aye sir!", replied Matt unsure about what this would bring, but a direct command from his wearer was a direct command.
The first change was at his chest. His armour plated dissolved and turned into black leather or latex following the contours of a fictional muscular body, a body that was quickly shrinking. For now his arms, legs and head stayed the same, supported by a leather clad body the size of a mouse. Finally the changes spread to his arms, which also shrunk in size to about a tenth of their original size with their hands remaining robotic and shrinking as their last part. Sleeves split from the arms and his torso, forming a leather coat. As the changes go down his waist a leather belt forms and his crotch shows evidence of a fairly massive package in that department. By that point the changes went down to his knees widening up to fill them giving him a rather comical look of a tiny toy sized body with a huge helmet and huge boots. Then his robotic feet shrunk to become what looks like armour cladded boots. Finally his head changed and shrunk, dissolving into a blob that became more and more organic before it reached its final size when it's front formed a pointy muzzle with grey fur and bucket teeth and its sides pushed out forming comparatively large rodent ears.
Jacob, still in control of the situation posed for the mirror, "Well I need to work on the change sequence, but I think I'll keep you that way for the moment.". He inhibited Matt's control over the camouflage options and arced out of the little mouse hunk. He then picked up Matt, who was still technically an armoured suit disguised as a tiny mouse hunk, perhaps 3 inches in height with a face that would be described as cute if it wasn't for his member clearly showing through the leather. Matt, now again able to show facial expressions struggled with being picked up, but essentially gave up as there was little he could do.
