"Katie, look! The label reads "Breasts Expansion". Maybe you can finally grow proper breasts instead of the ironing board you got." Tiffany shoved the bottle of oil into her hands. "Go ahead, try it!"
Katie got more flustered, partly from the mocking and partly from the swelling inside her panties. Plus Tiffany had failed to make the connection between the growth on her chest and the fact the first fruits she had eaten were shaped like breasts... She was totally oblivious of Katie's change for now, probably for the best. Katie didn't want to freak out her friend.
"Can I get some privacy at least? Maybe I don't want to rub my boobs with oil in front of you." Katie suggested.
"Whaat? I've seen your punny little breasts before in the changeing room and all. C'mon, I gotta see if this works!" Tiffany insisted.
"Let me try this in a bathroom perhaps and then I show you the results. I'll be quick."
