A Femboy robot has the special feature that causes him to grow additional data storage hardware as fat on his frame.
This becomes a problem(?) when a virus get into his system. The virus isn't necessarily dangerous to him, but the exponentially duplicating data, which was just meant to slow down normal computers, is overclocking his hardware and is causing his blubbery body to expand exponentially as well.
It'll only be a matter of time until his curves smother the entire planet.
I know I'd be filling him with files if I knew he had no specified limits in his programming (nor on his frame) that'd prevent him from letting bloatware really fill him like that...
Good thing that virus was such a big 'problem' that it caused exactly that to happen, causing the poor, overwhelmed femboy bot to overflow with blubber everywhere. His ass, thighs and hips definitely are a prioritary spot for this data storage mechanism, since they always seem to gain weight first and at faster rates than the rest of him, which might be due to his femboy nature.
Though when his ass could touch three walls AND the ceiling all at once before breaking through the house, he was getting pretty damn fat in general, and at the pace he was gaining, the files also needed some additional spots to bloat, and his belly followed, being the second biggest area on his body, providing him with a robotically divine, bottom heavy figure. He already had so much padding to go around, but his moobs also had room to grow. They wouldn't match his tremendous ass, but they'd put many female bots that hadn't been affected by any virus to shame with the chest size difference!
His unending bloating and limitless software+hardware combination (even if his hardware was very soft now~) were surely going to end up smothering not just the planet but everything, unless the virus itself stopped...but I had already made many copies of said virus on external hardware, and would be prepared if such a terrible scenario were to occur. Whatever happens, he won't stop growing~
