Tiff looked at the bottle she held "Gurenteed penis in every box" sounded corny but she know that she had to use it. She instantly drank it as soon as she got out of Katies sight. Tifff felt a weird feeling just above her sex as a lump appeared, it grew and extended pushing its way out longer and longer until her new member reached 4 inchs long "good thing it isnt erect" thought Tiff as she would have trouble hideing it.
She turned around to face Katie now, who was feeling her new rolls over. "Ooooh mabye you should lie down" Tiff suggested, "all that weight could hurt your back". "Yeah I guess I should" was the reply.
Tiff then helped Katie lie down slowley onto the floor, the suspense was killing her. Then as Katie finally lay back in relife Tiff could stand it no longer.
Tiff pounced on Katies lower belly and undid her pants, "Whats going on down there?" Katie Katie called to her "I cant see past my stomach". Nothing just relax" Tiff called back, sh then heaved up the massive belly revealing the thong like panties, they were very stretch already so Tiff quicklly finished them off with a loud rip.
"Ooooo that tickles" Katie squealed, then it started getting arouseing for her as Tiff plundged her now massive erect cock right into Katies warm inviteing sex. She moved in and out with inhuman speed, both girls started moaning long and loud. Tiff didnt stop, not until she unleashed a massive load into Katie. Then she fell back exhuasted, "how?" was Katies only breathless word.
As both girls tried to get thier breath back, Katie started to feel funny, differently this time.
