The Sit Plug was designed by ToyTorture as a trainings toy for his puppy Sit* to help him become fistable. The double-conic shape stretches the sphincter both soft and consistently, both being pushed in and pulled out. This maximizes the trainings effect. A sturdy and handy base is perfect for solo play and enabled regular training units.
The steps between the different sizes were chosen for a motivating yet challanging training according to ToyTorture's Anal Fisting 101.
