Yes; just once

"Damn," Vanessa clicked her tongue, "the office just isn't the same without princess shorty."

Just as Cora felt her face turn red she felt something else. At first it felt like she was stretching, but she was standing still. Gradually, she saw the floor drop away as inch after inch poured into her legs. The feeling nearly elicited a moan from her lips as she felt her clothing constrict on her body. Her shoes became too small, her socks slipped down on her swelling feet, her pants became too tight as her thighs and buttocks gained an inch or two themselves.

Cora's brown eyes began tingling as they lightened a shade, her hair became that much more lustrous and her voice became softer. Finally, what Cora had been waiting for: her breasts shifted in her top. Out of habit she had worn a bra that day which she could feel shift alongside her chest.

Cora looked down and once again had to stop herself from making noise. In slow, gradual spurts her breasts began to pump outward. Their growth seemed to gain in speed until Cora was watching her formally smaller, pert breasts push into her bra and blouse. She felt her bust rubbing against underwire and fabric as the expansion continued.
