The act of placing one's face in cleavage and shaking one's face back and forth, while saying Brrrrrrritsky, so that repetitive breast-to-cheek contact is achieved,
I was about to give her the motorboat...then she turned around accidentally gave her the backdoor brumsky. "BRRRRRRRRRRRRRR" Noiseperson would make during the act.
Beautiful hottie at the strip club agrees to a table dance for you, proceeds to strip down either to total nude or just with butt floss on, bends over, grabs her ankles, moves up to where she can surround your nose/mouth area with her glorious butt cheeks, and proceeds to jiggy them back and forth while you inhale/exhale rapidly! A most pleasureable, tasty, sweet-smelling experience most of the time.
Damn dude, that hot wench over there just gave me a million dollar reverse brumsky but she had a couple of straydingleberries up there in her nether region!!
