We have no idea why it's happening, but ever since Sunday night, Helen has been growing a penis. Without warming, my wife's clit expands and transforms into a working cock, a big one. At first we were both terrified, but with the appendage come other changes. Helen is different, she's more aggressive and stronger. It's a new side of her that I like.
But then why am I ashamed of what I want? Why can't I tell her how cool I think it is? Why is her new monster cock all I think about? Why am I having trouble admitting that I want to please her, that I want to give myself to her, that I want I want that monster inside me?
