Reggib Stit

"Say Reggib Stit." You say looking at the panicked beauty attempting to cover herself with her hands.

"REGGIB STIT" She repeats and her already large breasts start to grow until they're twice the size. She only just manages to keep them covered with her hands.
"What are you doing to me!?" She yells.

"Show me." You say and she removes her hands. The now enormous breasts are as perfectly shaped as they were before only now they're four times the size of her head instead of twice the size. You approach her and squeeze the massive mounds and jiggle them while she stands there.
