"Oh jeeze, what a long day.  (YAWN) Oh!  Hey!  Please hold the elevator!  Hey, wait for me!  Phew, got it just in time!  Um, 31 please.  Thanks."

"(Doors close. Elevator shakes somewhat violently as it begins to ascend) Whoa!  THAT'S never happened before!  I hope we don't get...Ooh...stuck."

"(Thinking to self again) I feel...light headed all of the sudden.  What...the hell?  My ass feels all tingly.  Ugh, keep it together.  I'm almost home.  Gah, my skirt feels...tight?  W-What the fuck?!  My ass!  It's huge!"

"(Still thinking to self)Oh God, I must be having an allergic reaction or something!  I hope they don't notice!  I-I'll just keep my skirt pulled down and...Oh no, my arms...They feel...longer?!  Oh shit!  Did I just...?"

"Oh my, I-I'm sorry!  I didn't mean to elbow you like that!  I-I don't know what's happening to...me?  Oh God...oh God, my hands are swelling!  They're...They're huge!  And my arms...I-I'm touching my toes without even bending over!  Please!  You've got to help me!  W-What kind of reaction is..."

"OW!  My feet...My shoes, they're...t-they're so tight!  No, please!  STOP GROWING!  WHOOOOA!  OUCH!  Mmmm...At least my big ass broke the fall...Dammit, those were my favorite platform shoes, too!

"Oooooh...I grew again?  Phew, I'm not even touching myself!  Another one of those and we won't be able to move at all in here!  Aw, my clit's normal sized again!  Er, compared to the rest of me.
