Smaller room? Bigger Sister?

You wake up some time later, and notice something is off, besides the fact that you are in your sisters body with a 15 inch cock that reaches your chin...no your boobs...your d-cup boobs. Wait your sister had b-cups originally. You quickly run to a mirror and examine your body. Your body is completely different now you are much taller, at least 6 foot and your body has filled out a lot, your boobs are well into d-cup range and your ass has filled out to match. Your figure is also much more athletic and your arms and legs have much more definition to them. And you are still sporting the monstrosity of a dick you created which actually fits your form alot better now.

A wave of arousal hits you as you are turned on by your new body. You start working your shaft with one of your hands and finger yourself with the other. You explore your pussy for a while discovering your weak points. You find your dick is incredibly sensitive as well and you find yourself close to climax.

You have a massive orgasm, your dick ejaculating like a firehose coating the mirror and yourself with a layer of your cum while simultaneously a wave of juices gushes out of your pussy soaking the carpet below the mirror.

After a while you come down off the high from your orgasm, you here a knock on your room door. Its your mother telling you that you need to get ready for school.
