"En Garde", said Matt, pulling out his fencing foil. Somehow his computerized mind was full of fencing experience. Jacob (1), now back to human was only able to retreat a bit, raising his arms as a piece offering. Matt giggled and put it back. Shy of a meter high he still seemed to be imposing to some degree. As Matt did an internal check on his systems, Jacob (1) got sparsely dressed.
"I wonder what my copy is doing?", Jacob (1) asked and they both went to the bathroom. What they found there was Jacob (2) bent over in a sort of spasm, his robotic body mimicking moaning. "Ahh I see what's happened", explained Jacob (1), "The design was not yet finished, you can get horny, but since you have no privates there is no way to relief yourself." Matt stared at Jacob(2) and started to feel his own groin which was empty as expected. Jacob (1) continued, "We could simply reboot him... or we could try to use it as intended." Matt was puzzled, "...use it as intended? Does that mean...?". Jacob (1) just looked at Matt and grinned.
Matt approached Jacob(2). The bat-robot did look rather attractive, curiously he started to sniff the private area. It didn't smell special as his sensors were measuring the usual trace amounts of solvents one could expect with all the plastics and paint. However there was something else, something caused by his programming. He was drawn towards it, feeling the irresistible urge to lick the blank area between the bat-bot's legs. As he did so, a wave of pleasure went through both of their robot bodies. As if on auto pilot he continued to lick, sending more and more waves to pleasure. Jacob(2) reached for Matt's hat, which was part of his head, and started to thrust his mechanical pelvis into Matt's face. In sync their ecstasy grew with every thrust and every lick, until something clicked and they both collapsed.
After a few seconds they sprung into action again. Jacob(2) asked the other robot, "Are you Matt?" He nodded and smiled at Jacob (2).
