Uuuuuh.
Three pipes blow air into my now gigantic body.
I feel my belly and boobs drawn upwards due to the volume of helium filling me.
I can feel the bed almost lifting up.
Oh man I'm huge.
The bonds around my feet snap suddenly.
And I float upwards doing a sort of handstand in mid air.
I emit a muffled squeal over the pipe in my mouth.
I kick my legs in the air.
Still expanding.
Mmmp.
Mmmmmmm mmm mmm…mmmmm
I'm really really big now.
