I want it to be humiliating when I turn into a berry. People will give me weird looks and stare as I turn blue, making me confused and uncomfortable but I'm too stupid to notice until my stomach starts to blow up. It'll start as a small potbelly and I'll grow flustered and try to hide it. But then I realize it's not just my stomach but my sides and back filling out too. My clothes grow tight around me and my shirt pulls up to show my blue belly. I'll start panicking and I'll try and push it down but it doesn't stop - I'll just feel the gurgle of juice under my skin. Now people will stop and circle around me, talking about how big I'm getting, asking if it's an allergic reaction or if it's something contagious, that I look like a balloon, that I'm putting on an act. They'll pull out their phones and record me. My clothes burst open as I'm forced to spread my thickening arms and legs, my body one big round ball and still growing. My crotch will sink between my knees and my sides will lift up and out until my limbs are sucked into my belly. My blubbers for help will become muffled as my neck disappears into a divot where my chin hits my chest and my round cheeks fill in the space until there's no gap. I can't turn my head anymore - I'll be forced to stare forward into the watching crowd as I feel myself expand even bigger. My hands bounce off my sides as my arms are swallowed to the wrists and my crotch finally presses against the floor. More pressure and then my feet lift off and I'm wobbling balanced on my crotch.
The swelling will have stopped but the humiliation won't be over. I'll be perfectly round, as wide as I am tall, and completely immobile. People will poke and pat me all over and push me into a roll. They can do whatever they want with me: make me their ball for a game, or squeeze the juice out of me, or climb on top of me like I'm a circus ball to walk on, or try to breed me. They can see if they can squeeze me through a doorway and get me stuck. I can't stop them and I don't want to even if I could.
