"God Karyn I wish you'd just shut up and join her in ridding my cock"
As Jon finishes his statement, Karyn who was mere inches away from having tried to grab the stone, gets sucked into Zoe.
Suddenly Zoe's small body feels heavier, Jon can feel her legs extending, straddling more of his body, her ass filling out and becoming more plush as she bounces up and down his shaft.
Her midrif tightens, her waist constricts revealing a magnificently sculpted washboard abs.
Her chest starts to inflate, becoming fuller and rounder, her hair lightens going from black to brown, then red to blonde all the while gaining in volume and length.
Just as it starts to turn platinum and tickle Jon's balls with it's length, he looses sight of Zoe/Karyn's face behind the up and down sway of her now K cup breasts.
