Your sister

You decide yourself for your sister, since she is younger and even hotter than your mom. You take her suit and start to put her on. As you are completly her you look down at yourself. You could feel and see her enormous breast on your chest, zou could see blonde hair falling into your view and felt how big her butt was. You were now wearing some short jeans and a T-shirt. You go out of your own room and wait, just to be sure mom doesn't see your sister in your room. You hear that she wakes up after 10 minutes, without questioning what happened. You see her, continuing her day like nothing happened.
