Barbie was ecstatic. She had actually managed to transform her sister, but she only know for certain due to Tammy's scream. Barbie wanted to be able to see the changes for herself, and she also wanted to test the limits of the program. It was time to try to accomplish both.
Barbie entered a series of commands into the program. Her intent was to make it so that Tammy wouldn't be able to help but obey every command Barbie gave, and to have Tammy feel compelled to walk into Barbie's room, lock the door behind her, and stand in the middle of the room, and not to move unless told to.
Barbie could here movement from Tammy's room, followed by Tammy entering the hall and approaching her room. As Tammy entered, Barbie's eyes went to Tammy's flat chest. Tammy was wearing a revealing shirt and large bra that looked comical draped over her flat chest. Tammy was also wearing a short, tight skirt, and what must've been a thong underneath based on the definition of her buttocks as she turned to close and lock the door. She also wore white socks that stopped short of her knees.
Barbie was so intent on the flatness of Tammy's chest that she didn't notice Tammy's confused, rattled, and temperamental face as she made her way to the center of the room. Tammy blew the bangs of her shoulder length blonde hair out of her face as she looked intently at Barbie.
"What the hell is going on?" Tammy asked angrily. "Why did I come in here, and what the hell is wrong with my breasts?! Did you--"
"Stop talking," Barbie said calmly. Tammy, despite all her desire to do otherwise, clammed up.
Barbie grinned widely...
