mexican ripcord

a male inserts a long plastic, or rubber string of anal beads into one's anus. the male then rapidly and forcefully pulls the anal beads out of the victim's anus. Due to the unexpected pressure change of the rectum to the outside world, the feces of the individual spray out in a "thumb covering hose fashion." the action also creates a starting engine/shart noise that im comparable to a lawn mowers ripcord/ starting mechanism.

A sexually explicit act. The male participant proceeds to anally gape another willing participant. Once the ass is suitably opened the males balls will be dropped in the open stretched ass. The asshole then begins to retract to the original size. Once the correct tension is achieved the male begins the jerk off while pulling his balls out swiftly and quickly as he ejaculates on the back of his partner. This turn the stretched partner into a wet-back as the sudden ball removal is the ripcord.
