Self-control

It never fails, give a guy the ability to change his own body at will and he'll invariably try turning himself into a girl.

True, some hold off a few hours or even days choosing to get buff and improve their manhood first but sooner or later they all get to wondering what it would feel like to have their own tits.

They usually start small, just a pair of perky B's to see what it's like but after they've taken that first step they just have to go the  rest of the way. Long hair, nice ass, smooth legs, the whole package so to speak.

After that they rarely even think about going back. It feels so good all they want is more... well, more!

The more they change the better it feels, the better it feels the more they want to change. The result is a feedback loop they can't resist. It rarely takes more than a few hours before any trace of masculinity is wiped away altogether and all that's left is another happy horny bimbo.
