The act of inserting a vibrator into a female's vagina, then proceeding to fuck her in the ass. The vibrating sensation is felt through the thin membrane separating the vaginal canal and the anal cavity, hence giving the affect of a vibrating anus. A must try!
I shoved a vibrator in your mother's cunt then fucked her in the ass until she bled, best vibranus ever!
