The act of taking one's penis and wrapping it around his own wrist, to where the head is tucked back out of sight. In doing so, you have the fashionableappearance of a fleshy watch band. Perhaps it should be called the Italian bracelet, but it is more of a counter to the Irish wristwatch.
When receiving a hand job, the man's ejaculate lands on the female's wrist and, by gravity, runs around her wrist. This creates the look of a white band on the woman's wrist. Popular because it normally requires just 2 to 4 ropes.
I remember in seventh grade at the movies Courtney gave me a handjob. I came so quickly, she got a Riverton Wristwatch.
I'll never forget the Riverton Wristwatch I gave her after a nice HJ.
