Suddenly you feel a tingle on your chest. Than your were waved by pleasure.
You look down and see that your not small breasts under your tight dress bulge out and become ample and bigger. With every wave the breats expand more.
After a couple of moments your breasts have just the right size for water melons. The are firm and perky. Your nipples are errected so you can see them through the hard wear outed fabric of your dress.
What a luck that you doesn't wear a bra instead the straps would torture your back.
But the breasts aren'#t the only change.
Your buttom also expands until he is now bigger and sexier than before, so now you can see the bulge on the back side of your dress.
Also you notice that something has changed with your mind.
During the continous pleasure you have the demand to swirl the two braids of your long blond hair.
Because the new tightness of your clothes your dress is a bit lifted up and that aroused you.
With out thinking you put of your panties to feel the cold air in your crotch.
Automatically you have the demand to put something into your pussy.
The feeling overhelmes you and you can't think to anything others, so you search for an object which can put in.
Accindental you find a dildo in the stuff on the table.
You take it and begin to use it.
Instantly you get an orgasm and continue to pull it in and out.
You notice that your sex drive increases rapidly and also your IQ gets lower, but you can't do anything against this.
