I have had very little throat trampling, but what i have had i thoroughly enjoyed :-)
In this pic the lovely legs and feet belong to Mlicious in detroit, a member here, and part of the Maitresse Society in detroit. I travelled up from charlotte, N.C. for one of their FemDom/malesub parties, which seems to always have plenty of trampling.
It is a GREAT/FUN feeling to be under a lovely Lady's entire bodyweight as She stands on my throat. It is definately a feeling of vulnerability and "suffering". :-)
i felt lucky to be the ground She steps on.
