Rule of Thumb

During coitus, if you're ready to move from the pink to the stink, but you're not sure if she's into it, you can always gently mash your strongest thumb into her butthole, as if to say, "What do you think?" If she smiles or goes with it, trade your thumb for your cock Indiana Jones style.
