“There you go, now you just get comfy up there my lovely birthday baby balloon, I’ve still got to get a few things ready for your special present%”  
“M-mmf, ooh, T-Twinnie, is the puffy padding inside here supposed to be… oooh… v-vibrating?_{”  
“Hm? Oh, oh! Right, almost forgot to mention, I did have a little bit of fun putting this one together for you, too. Just so you don’t go and try to ruin your surprise early, I might’ve added a few little things inside these puffy and plush pampers around your rump, just so you don’t get too far if you try wriggling to escape… or wriggle too much, in general}”  
“Like… oooh… l-like what?”  
“Oh, just a few fluff-bangs and forty millimeter balls of fun, one for every year%”  
“For every… eep.”  
“Mmhm~ And, just to keep things especially fun for you, they’re on a few timers! I’ll try and have your big present ready for you before they all go off%”  
Paff!  
“Oh, guess that fluff-bang was on a shorter one than I expected% Or were you just bouncing a little?_{”  
“Mmmmf}”
 
It’s Minty’s birthday today, and unfortunately I wasn’t quite able to get his proper puffy present done for him before the actual day of, so I decided to improvise a little and give myself a bit more time to prepare it~ I’m sure Minty won’t mind the wait, though, especially when he’s got a pair of puffy rumbly padding on underneath some thick, heavy, cushy padding, especially when both start swelling and filling up to squeeze against him even more~
 
I just hope he doesn’t go and start bouncing too much, those extra surprises inside are rather sensitive, and I wouldn’t want him tiring himself out before he can fully appreciate his present~
