Yorktown Streetsweeper 

When a couple, usually a promiscuous gay couple, is engaging in intercourse and the index finger and thumb are inserted into the anus of either partner, and then used to apply a "Titty twister" to the opposite partner. (Usually done while fingers are dripping in feces for full effect.)

"I gave Dave the best yorktown streetsweeper he's ever had - his prostate practically burst."

When she gave me a yorkstown streetsweeper I was very surprised!
