When a girl puts peanut butter all over her vagina, and lets her dog into her room. Her dog then licks her vagina until all the peanut butter is gone. The woman will get sexually pleasured. This is just like a man eating a woman out, so the woman has a high chance of an orgasm.
Sally: Want to come over tonight so we can eat each other out?

Carley: I can't my mom already caught me watching lesbian porn, so now I'm grounded. Maybe next week!

Sally: Seriously, now I have to peanut butter doggy time.
