"So, what do you think?" Biff asked, holding up the lacy bra to his chest.
Sarah looked at it and felt her crotch getting wet at the sight of it. She was already imagining what it would look like on Biff's naked body.
Biff saw the expression on Sarah's face and smiled. "I guess you like it." He then moved on towards another rack full of sexy lingerie.
Being in a store full of sexy female underwear was a definite turn-on for Sarah, who slowly became more muscular, as her hair shortened and her breasts slowly got smaller. But she wasn't really all that interested in the shopping part. Honestly, she never understood why girls liked that so much. She paused, as a voice whispered at the back of her mind, telling her that something was wrong, that she should understand why girls liked shopping so much, because she was a girl. But that was ridiculous. Sure, she was female. But she wasn't a girl. She was just one of the guys.
"How about this?" Biff asked, his voice pitching higher, as he stood there holding another sexy bra up to his chest, which already had a pair of A-cup breasts that were slowly getting larger and larger.
