As Leslie turned around to face the shelves again, Alex quickly switched incognito mode back on with trembling fingers.
After the lag disappeared, they navigated to the physical tab again.
So many choices, so many choices, what to start with? Breasts? Hips? Face? Ass? Musculature? Height?
Gripped by crippling indecision, Alex scrolled up to the top of the list again and just decided to start alphabetically and go from there.
Investigating the ass sliders revealed a wide range of options; size, tone, shape, circularity, bounce, firmness, texture, verticality, perkiness... Plus a checkbox that was check by default for "adjust clothing to fit." Curiously, there was also a set of butt sliders which had identical options. Redundancy seemed to be the name of the game.
Alex thumbed over the size slider and looked up at their friend.
Leslie had just started to bend over to check a lower shelf as Alex began the changes which presented them with a clear view of her derriere as it expanded, dragging her hips along with it. It was hypnotic to watch as the nearly flat ass swelled, becoming full and sitting between wide, curvy hips. If the "adjust clothing" setting hadn't been on, her jeans would have surely ripped, but they slowly morphed along with her.
Alex quivered, aroused, as they looked at their freshly filled-out friend. They made a few more tweaks, increasing firmness and perkiness, making Leslie's butt a little more toned.
Numerous other little tweaks and Leslie was now the owner of a rather pleasantly pear-shaped and callipygian body.
Alex could tell that the way she walked had also changed, from the small movements Leslie made as she searched the shelves. There was more swing to her hips that emphasized her new derrier, which was cleanly pressed against her expanded jeans.
Absolutely all doubt that the app worked was gone. Now Alex just had to decide whether to leave it there for now or continue with the changes...
