Stuck in the bottom half of the giant suit, you find you can't move your legs. The instructions say that you'll get your mobility back when the whole of the costume is on. "Help me with the top part" you say.
Jack lifts the costume towards you and you wriggle in. Once again you feel like you've being stretched and a little inflated too. The body sits upright on the leg part, and your head pops out. Your arms find the arms of the bear and your penis wriggles into the fat furry condom. "Oooh!" you say, enjoying the feeling. You've still immoble, though
"Your face looks fatter." says Jack "Ready for the head."
You reply yes, and Jack stands on the crate and pushes your head down over you. Your cheeks feel like they're puffing out by themselves and your belly feels like it's inflating again. To your releif you find yourself able to move, although you have no sence of feeling where your body ends or the costume begins. As far as you are aware you've an 8 foot bear with a 5 foot wide belly and footpaws the size of dinner trays.
"Woah!!" gasps Jack "Careful where you sit!" although you guess he'd actually enjoy being sat on by you.
