First time I was impaled with this Bad Dragons large size, medium firmess Gryphon. It is mounted on a homemade fucking machine with about .75 hp and upto 200 rpm. Had a hands free orgasm after a 20 minuet ride. This is the best way I have ever used my Gryphon and can't get enough of the brutal stretching and thrusting my machine generates. The mount was 3D printed to hold the oversized base and could be adapted to any Bad Dragon toy.
