This is absolute hardcore anal stretching! Mistress Sandra has mastered the game of immediately recognizing and assessing the limits of hers. When I put myself in their hands, I feel absolutely safe and in good hands. Every move is perfect. She inserts this stainless steel spreader into my anus and thereby widens my sphincter muscle bit by bit. The feeling is awesome and yet it slowly brings me to my pain limit. This is real BDSM the way you want it to be. Lovingly sadistic!
