In the kitchen

You sneak into the Kitchen and you see that no one is here. You could tell that Katlyn Is now sitting watching tv and your mother and Miley are in there bedrooms.

You decide that you should pretend to be your mother or your sister and portend to walk into Taylor playing with herself.

But who to choose. If you choose your mother it would be funnier. But if you choose Miley she could be expecting a round 2 of the sex you had earlier.
