Shade did not care, the sensations were too much for her brain to think about anything else, and nothing else mattered. She was taking out her stress from weeks past that weren't even Alexa's fault and the stress developed from their recent bout. All she cared about was plunging her cock in and out of Alexa as hard as she could for as long as she could, and it would be a long time indeed, considering she had both her arms and legs replaced with cybernetic limbs, her stamina for thrusting was quite literally infinite, her back was still human however, but her fit nature would ensure that not even that would tire soon. "What?" Shade said through a few thrusts, still panting, a few seconds later she forgot what she was talking about as the sensations overwhelmed her once again. It was like a drug, she should probably stop and check on Alexa, as things did seem strange but clearly they were both enjoying themselves. So Fay did what Fay was best at, pounding things, not just flesh on flesh either, with her cybernetic enhancements she was pretty good at punching holes in walls, metal sheets, skulls, pretty much if she could make contact with her fist, there would be holes. This pounding however, was flesh on flesh, and there was already a hole for her to pound, she gritted her teeth and sped up more, hammering Alexa's pussy into oblivion and overloading her own optical sensors.
System overheat........Emergency counter measures engaged.....disabling heat vision, night vision, xray vision........optics function 60%.....emergency emergency countermeasures engaged, disabling vocal box synthesizer. Shade's moans then turned to nothing as only air came out of her mouth.
Overheat potential reduced to 40%.......rebooting optics in 5.........4.........3........2........1
Things went black for a second but she kept pounding, ten seconds later her optics booted back up and she could see Alexa again, although her noises were still air as her system had shut down some primary functions to prevent an overheat.
Danger! Overheat potential at 45%.......further increase will shut down optics....system lock up to follow.....optics capacity reduced to 50%.
Her vision went black and white, all color drained from the world but she kept at it, if this is how she died it would be perfect. The system would never shut down her heart though but it would shut down everything else to preserve itself and her.
