A sexual act in which a woman lies on her back on a bed or couch with her head hanging back off the edge. The man then enters her mouth while playing with her breasts. A snowblower effect can be achieved at orgasm by removing the penis and showering the buxom lass with semen across her midsection.
My girlfriend has trouble getting the whole thing in her mouth, so we do the Chicago Snowblower so it slides down her throat easier.
