Ian decided to click on Transform. Suddenly, both models - Lily and himself - lit up in various segments. Some of the older menus also disappeared, leaving 'Copy', 'Paste', and 'Edit'.
"Hmm...." Ian thought to himself. With no teacher around, he still had at least some time to play around with this. "Let's try..."
Ian tapped on Lily's chest, and saw her boobs light up on the screen. The DS automatically zoomed in, giving him a rather close view of her chest, wrapped up in that school uniform. Tapping now on edit, a dropdown of more options appeared.
"Remove? Sure!" Ian sniggered, tapping the button, and watched the shirt on the model of Lily disappear. Left behind was a plain white bra which covered her modest boobs. By chance, Ian looked up and nearly dropped his DS. In front of him, the real Lily was also missing her shirt, wearing only a bra! And she continued to sit as if nothing happened!
"Is this for real?" Ian asked himself, before feverishly tapping at the screen some more. Shortly after, Lily's boobs swelled from their previous modest size to gigantic DDs. Her bra matched them, and no one in the class seemed to notice anything - not Lily, whose own chest had just effectively tripled in size, nor any of the guys who periodically glanced in her direction.
"So that means..." After a few more presses, Lily had long, toned legs, and her uniform had been reduced to thigh-high stockings, a ruffled miniskirt and a bra. She seemed none the wiser, despite being significantly taller, more well endowed and very provocatively dressed.
"Wonder if I can do myself too?" Ian wondered, before testing it out. Naturally, the first thing he did was give himself a massive cock. Feeling the change in his own pants, he wondered. "Well I felt it.. why doesn't anyone else? Could it be the DS?" Deciding not to let a good thing go to waste, he further transformed himself, becoming taller and more buff.
What now, though?
