You enter the bedroom, where you ordered your brand new Shelby robot pony to lay and “rest” after you came home from work, discovering she swallowed the couple of ponies from the nearby apartment, with the purpose to assimilate their chemical components for energy so she could help you economize on the electricity bill. How… gentle? Whatever, you had some sick morbid attraction to that squirming belly of hers, so you gathered all the will you had to order her to go to the bedroom the day before today, and now as you enter you are greeted by the noisy gurgles and boiling of your probably faulty robotpony’s belly, that now appears soft and swollen, with nothing moving in there. You sigh, trying to kill your sick arousal.
 
“Seven-eight-nine, what is the status of the, um… recharge?”
 
“Digestion of neighbor individuals designation PrettyFlowerPone and PoneButt at 75%, Master.”
 
She answers you while an actual damn progress bar appears on her belly, a deep and muffled groan resonating from the deepest part of her belly… energy converter, whatever it’s called. You both stare at the swollen sack, before a thunderous belch escapes her mouth. She doesnt mind it at all, not knowing that “gastric activity” is a source of embarrassment, but you mind it… greatly, as a terrible heat assaults your body.
 
“Oh… cool. I hope this doesn’t cause you ventilation issues, hahaha.”
 
“Rear ventilation activated, Master.”
 
“No wait, don’t actually do it- Shit, ugh.”
 
You curse trying to reach the nearest window.
