Kate brings Meg home

After shutting your first shrunken girl away, you go upstairs to greet your girlfriend.

"Hi John", she says as she walks in, "hope you don't mind, Meg is just gonna stay the night with us".

"Thats fine", you reply knowing this only means there will be more girls in your harem.

Meg sits down on the couch as you walk over to your girlfriend. "I'm gonna go take a shower, I'll be back in a sec", Kate says as she walks up the stairs leaving you alone with Meg.

So, which one are you going to shrink first?
