3M 

A sexual act far worse than the well known Chicago Sunroof, involving stuffed animals, dry ice, dead pandas and Susan B. Anthony Dollar.

I though John was going to give me a Chicago Sunroof but then sick Bastard gave me a "3M" while screaming "DADDY needs his 13" I haven't stopped crying.

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.

3M 

A variation of the famous Chicago Sunroof, a highly erotic and invasive sex act using the Susan B. Anthony dollars, 3M tape, and a submissive partner. After the completion of the act, medical personnel are usually needed to remove the coins from your anus. Not for beginners.

John is usually never around when the shit goes down, but I was finally able to 3M him and he was shitting change for a week! His screams for one more coin to make 13 in his ass were oddly sad and endearing.
