Due to the popularity of Sportfucker's Thunder Plug, they went all in and turned it into an a-lock!
Just like the original, the plug portion actually taps your prostate as you move. There is a three part interior which creates a deep, penetrating thud. When worn for an extended period of time, the constant and steady tapping on the prostate will slowly and steadily cause you to throb.
The Thunder Plug A-Lock has a long, stretchy connector that goes to a silicone sling to connect your junk to your butt.
