You go on vacation to your country house, enjoy the great outdoors and take a long walk. On the way back you find two bracelets on the ground, you pick them up and put them on your wrists but when you put the second one the spikes come out and stick into your skin, you feel tingling in your arms then it moves throughout your body.
You run to your house and your way of running becomes more feminine, you reach your house and you enter, you feel your hair tickle your back, you go to the bathroom and you see your face become more feminine, your clothes also change.
