Like Martin said, steel, crotch chain, elbows, gagged, throat, hogcuffed... all elements that I love. What I enjoyed the most was the strain of having to hold myself up to keep my nipples off the table. After a while, it gets tiring. Martin then slides the wand between my legs and leaves it there. It's so FRUSTRATING to feel all those vibrations, yet it's not hitting my sweet spot! Frustrating until Martin grabs my hair, pulls my head back and pushes that wand to the right place. I was cumming so hard that I was smashing my clamped tits into the table and it didn't even phase me lol.
