I'm Kitten! Your cute gym crush! You let me work out with you today and now we are back at my place... I thank you for working out with me and then I decide to show off one last time... In my tiny pink shorts and tight top, I do some squats for you. But I know your favorite was when I was bouncing up and down on the yoga ball. I grab it and plop my fat round ass on in. Humping and grinding on it a bit... I think I would look pretty cute as a yoga ball myself, don't you? I hand you a pump and ask you to start filling me up as I keep grinding on my yoga ball. Bigger and bigger I get. I stand up to show off to you my new swelled up belly. I look 9 months pregnant and I think its hott. I ask you to do a little more... but don't pop me (; You make me swell more and more as I'm bent over my yoga ball. Hey wait! Thats too much! You won't stop pumping me up and I can feel my belly stretching more and more. I beg you to stop but the feeling is so good. I huff and moan and more air is pumped into my expanding belly. I dropped to my knees from the pressure as my belly blimps up to looking like I'm carrying triplets. My ass is looking huge and my belly is hanging between my legs. The perfect view of my underbelly as you play and fondle with my ass. You help me up and I realize I need to get out of here. I waddle around with my massive belly looking totally embarrassed. You corner me and start poking at my belly teasing me as I beg you not to make me burst! I continue to pant and moan with my new balloon belly as you stick the hose back up my bouncing butt again! Plopping down on my yoga ball being filled to the max. I can hear my belly creaking and stretching. I moan in pleasure but I don't want to pop! More and more and more you make my swell. My back on the yoga ball and my belly in the air... its happening... I'm... I'm - I'm gonna POP!
