I was in my early 30s and my dominant MIL, R, was in her 50s. My MIL was a graying voluptuous lady, that always wore seductive clothing, and especially loved, showing off her beautiful breasts. Right after we married, my wife gave her an open ticket to discipline me whenever she felt I needed it. Coming from old school, Germany. She definitely believed in disciplining me with a cane. To keep it from being a sexual experience, she would strip me naked, then suck my cock and swallow my cum before the whipping. She believed that, swallowing my cum and taking my semen and wiggling sperm into her belly empowered her for the whipping. Truthfully, having an orgasm prior to a whipping actually made the painful blows more intense. After she sucked me off, she would take me outside to her favorite whipping bench that a Carpenter made it for her out of wood. She would give me the choice to be buckled down, or be a man and voluntarily hold myself down for all the strokes. If I knew she was pissed off and was going to lay on the strokes, I would beg her to strap me down. Taking her rattan cane she would deliver 13 painful strokes, administering one every 30 seconds until my ass was completely striped. Writhing in tears She would rub arnica oil into my just caned cheeks that made the stripes hurt even more. My mother-in-law loved strap on sex and see me bent over in pain gave her the perfect opportunity to strap on her 9“ x 2“ cock and give me a good fuck. She definitely put the fear of the goddess in me, and whenever she told me that she was going to give me a caning I got sick to my stomach.
