What we happens here is slow progression of breaking me down. After being tied for over 45 minutes on top of being for to orgasm, I've had more than I can take. Loss for words, loss for energy, in tears, adrenaline brought to sky high levels, then crashing after orgasm - I was done. But with Martin finishing me off with the nipple clamps to the ceiling has my pain tolerance eating away at me until I had nothing left.
