Girl Vengeance
An M2F (and a Little F2M) Transformation Tale

When Tina finds her husband Billy and her best friend Maria in a compromising position, she decides to get revenge! At first she thinks about hopping into bed with Maria's boyfriend Carl for revenge...but then a much more fitting plan occurs to her. Using a newly developed hormone, she makes Billy undergo a total gender transformation, turning into a hot, curvaceous girl right in front of them! After Carl puts Billy in his place with a brisk spanking, he then uses Billy's new girl body in the most shameful ways! But Tina has one more trick up her sleeve...she has taken a little of the hormone herself, just enough to develop an interesting bulge in her bikini bottoms. Now she and Carl are sharing Billy, utterly humiliating her husband!
