Rocky Mounting is when the man/woman with strapon/top puts on first one condom, followed by a large even spread of extra chunky peanut butter, only to be followed by yet another condom, so as to trap the chunky creamy treat inside of them. Then the phallically studded partner starts to consummate the loving act with or without added lube.
