Asleep

Asleep. Which is great. As you go over to his bed and wave in front of his face, he only lets out a loud snore and you attempt to put Jenny on Kyle. The whole house would be more quieter with at least one of them gone, and you are pretty sure Kyle would have a blast going through puberty again.

Then upon realization, you sneak out of Kyle's room and into your older sister's, fishing out a remote controlled vibrator. Grinning, you attach it just at the base of Jenny's pussy, on the inside. You aren't sure how the bodysuit works, but if it does, you can turn Kyle into a wet mess that looks like Jenny.

Now there is a Kyle who looks like your youngest sibling snoring, with a built-in vibrator wedged somewhere in her groin.
