1) To perform fellatio (dick-sucking) similar to Deep Throat, where the entire penis

determines the name of the act, i.e., two fingers would be a Triple
performee's ass sets off the mighty, uncontrollable
finale'. (Sometimes variations including gentle scrotum-sucking
by performer, enhanced by alternating stuffing of a nut into
mouth opening not more than what would cause a breathing restriction is said to enhance
the eroticism level for both participants);
"Dude, my #1 squeeze insisted she Double Deep
me last night. It was awesome,...bigtime. Way better that her best Rusty Trombone has ever
been! Whoa. I still tingle!"
