You found a special herb that can make woman expand in all the right places and makes them uncontrollably horny. So you decide to test it out my putting some in Step-Mommy's breakfast. In a few hours you here Step-Mommy calling you into living room where she has clearly grown. Her boobs are busting out of her bra and her skirt is so tight from her ass and belly growing she can barely squeeze out of it. In no time she is playing with herself right in front of you. She can't help herself she is just so turned on with her new found size. What an interesting day.
