I use two fingers.
First, I find the right spot.
Then I rub it up and down, up and down.
It’s getting wet. Do I really want it now?
I stop, when I feel that I absolute want it.
Then I use my other finger. I love tapping it on the right spot.
Then I put it in.
When I get it out, Ahhhh what a relieve.
I absolutely enjoy online shopping. $3000+ of it.
