I made friends with a very friendly and nice Zebra guy the other guy! His name is Samedi!
 
After hanging out a few times with him, he asked me a weird question one day. “Do you like balloons Winter?”
 
“Of course!” I replied, I mean, who doesn’t? they are awesome for birthday parties!
 
“Oh, please come tomorrow to my house and I’ll have something I think you’ll like”. He told me.
 
The next day, visiting his place, I was delighted to see he made a little doll resembling me! Even a little scarf~ But my delight quickly turned into confusion when Samedi got a weird grin on his face… he took a deep breath, and started blowing up the doll through its rear end!
 
Confusion quickly turned into surprise as suddenly I heard some weird noises coming from my stomach, and the sudden sensation of fullness started to overcome me. Looking down, my belly was rapidly expanding!
 
“H-Hey! stop that!” I said as I tried to reach them to take the doll away, but I just felt so full… I couldn’t move from the pressure, and it wasn’t long before other parts of my bodies started expanding too.
 
I heard a giggle coming from Samedi, “No worries friend, you’ll be a lovely balloon soon enough”
 
He took another deep breath and kept blowing the now very round doll… and another, and another, it was just a few minutes but to me it felt like hours, my hooves were now sinking in on his body, a gigantic expanded belly that was connected to a enormous inflated rump… on which Samedi was now laying down as he kept blowing into the doll.
 
“Don’t worry Winter, you’ll be back to normal soon, after I have a little more fun with you~” said Samedi as he resumed back to his work.
 

 
One thing’s for sure, Winter’s not going anywhere for a little while!
 
(thank you to my friend Icy for including winter in this).
