If trampling is your thing, I will probably choose an MX outfit because of the boots. Imagine those tall heavy boots playing with your delicate exposed cock... so much fun to be had...
Of course, one of the benefits of biker and MX gear is the weight and the body protection that goes with it. The Master feels powerful and the sub feels weighed down and restrained by it.
Biker / MX
The ideal biker has full leathers, gloves, boots and a helmet with tinted glass (of course).
Incredibly sexy and hot!! Of course, if the suit has zips in strategic places then all the better.

Biker/MX
I design fetish gear and so my bike suits have full leather linings and plenty of zips to have some fun. The helmet is interesting too and I have some very nice examples depending on your interests.
