Growth-XX
A Size Matters spinoff
In Size Matters, we learned of the misadventures of Adam and his bottle of Growth-X pills. But what happens if another guy who's unhappy with his penis orders a bottle? -- Over the past two years, this story has grown to encompass all my major fetishes and then some. Expect gender bender, breast expansion, latexification, a lot of transformation and wholesome hedonism with a pinch of here and there. --
