Squat Exhaustion - BDSM Predicament

Hi, I'm 43-yr-old Sammi Starfish, your favorite real life milf wife and taboo role player. This was one of my most difficult bdsm predicaments yet. I worked up such a sweat. The reason is that my hands are duct taped to my ass cheeks. So I can't move without spreading my own ass apart revealing my juicy milf asshole to everyone. Furthermore, I am tied to a 20kg weigh plate in such a way that I am unable to stand up. So I am stuck in a squat position for the entire length of the video. My thigh muscles were so tired that I didn't think I could go any longer. But my husband would not untie me until the video was completed so I had no choice but to deal with this extreme exhaustion predicament. What a dumb whore, existing for entertainment.
