You feel shocked as she states that she wants to feed you even more, but your belly and a small part of your mind have already begun to accept this. Your stomach rumbles loudly, the pain still very much present; each passing second drives you closer to wanting food little-by-little.
The nanny smiles and pinches your cheek. "Stay here honey-buns! I'll be right back with some food for you..." She walks away for what seems like an eternity, but was really more like a minute, as she comes back out with a large tray. Setting it down, you see another large bottle and several good-sized containers of baby food, each about three times as large as ones you'd seen fed to "normal" babies.
"Here we are, sweetie!" She puts a bib around your pudgy neck, the thing rather large compared to your bare torso, before popping the top off one of the large jars of baby food. She dips the spoon down into it and aims it towards your mouth. "Say ahh!"
Part of you wanted to resist. Wanted to preserve your dignity. You weren't a baby, damn it! But the milk still kept you relatively-relaxed and, more importantly, hungry. You open your mouth while wondering what this mush will taste like, and find yourself overwhelmed. This stuff is amazing! You gulp it down and open your mouth, hungry for more. It tastes like a gooey, mashed-up cheeseburger, and probably the best thing you've ever eaten. The nanny happily responds to your now-grinning face by getting another spoonful of the baby food and putting it into your mouth.
Finally, your belly was beginning to feel relieved, with the key word being "beginning". You continued to eat the food this wonderful woman was feeding you, not really noticing the effect it was having on your waistline.
Your stomach immediately felt more bloated than before, but was beginning to fill up with soft, doughy fat, the once-flat surface slowly swelling. Your entire body actually seemed to get fatter with each spoonful: Your face was plumping up, giving you round, cherubic cheeks, and a forming double chin. Your arms that rested on your sides fattened as well, not that you really wanted or needed to move them anyway; your fingers and hands became cute and fat. Your chest, once toned like your stomach, was now swelling out into a fine pair of plump boy breasts with widening nipples; the bib also began to fit your body a bit better as it shrank in comparison to your larger form. Your diaper began to feel snug, as your thickening hips, butt, and thighs grew into it, causing you to feel quite comfy. Your legs slowly grew to become just as unneeded as your arms, fattening with your adorably plump feet and toes.
As the nanny fed you more and more, your body grew and grew; the contents of each jar of baby food disappeared into your expanding stomach. Soon, all four jars were empty, leaving only the bottle which she also popped into your mouth and you happily sucked on. Once all was said and done, she smiled and set aside the tray.
"My, my. Looks like someone had quite the appetite! " She gently pat your huge, sensitive belly, causing you to giggle childishly. Now that you had been fed, you felt much calmer and more relaxed. You wonder why you ever hesitated to stay here. She reached her arm behind you and began to pat your back, causing you to let out a few large burps. You feel your large form, noting how soft and jiggly it is. "Such a good baby." She pinches your very chubby cheek as you glance down, looking at yourself curiously and wondering how much you weigh...
