3M

The 3M is a sexual act first popularized in Chicago. The 3M builds off of the Chicago Sunroof. After giving them the Chicago Sunroof, you cum in their ass and seal their asshole shut with a piece of tape, preferably 3M packing tape. The tape is ripped away while performing a second Chicago Sunroof.

Last night, John gave me a righteous 3M. I don't think my asshole ever felt so smooth. He's certain to make his thirteen with 3M skills like that.
