invisible Wrist Watch

After having sex with a woman you don't want to forget, ejaculate in your hand and give her an Indian Rug Burn where her wrist watch would be. Then Everytime she goes to look at the time she will think of you.

So Davey and I keep sharing Sally as a sex partner but she is always calling Davey not me. But last time I gave her the old Invisible Wrist Watch and now she calls me like clock work!

Inverted Turtle

When an individual is performing oral sex on a male, they cup the balls in the palm of their hand and insert their middle finger into the bunghole. The term comes from the way the hand of the person administering it looks like a turtle that has been flipped over.

My girlfriend was sucking my dick and without any warning she gave me an Inverted Turtle. It felt so good I immediately busted a nut in her mouth.
