A method for holding in a poop that is very persistent that utalizes the seatbelt and a tennis ball. When you feel a poop coming on, place a tennis ball directly under your butthole, next put on your seat belt and pull it tight, this will cause you to be pulled down onto the tennis ball whilst sitting in your seat thus plugging your butt hole and keeping your shorts clean from invasive poop.
Heading off shore twenty miles, Brian felt the second wave of troops coming to destroy his short pants so he strapped on the reverse ball gag.
If a ball-gag appears in a work of erotica, one or more characters must use said ball-gag before the story's end. Variation of Chekhov's "gun on the mantle." Bonus points if you put the ball-gag on a mantle.
That ball-gag hasn't been used yet, but it seems important - it must be a Chekhov's Ball-Gag!
When receiving a nice blow and you get greedy and try to shove the balls into the girls mouth as well pushing her past her limits instigating the gag reflex....
The party was over when I tried to tap the balls in last night w/her during my blow. She started Ball Gagging....
