Ok, you've chosen your number. Now turn up the dial just a little bit on your little friend. Feels good, doesn't it!
Now, you need to get your panty collection up to or down to the number you selected. You've already got 5 in the drawer, so that's a start. So one of two things is going to have to happen.
1. You have too many panties in front of you, and you need to throw away some more to get down to your number.
2. You don't have enough panties in front of you, so you need to build up a larger supply.
