Both, my wife (6'2" 190 lbs.), & my mother-in-law (6'3" 220 lbs.), strip me (5'10" 165 lbs.) & put me over their knees, whenever, they think I need a good spanking. Both, are stronger & much more dominant than me. One time, my mil, took me from behind like this, (after my spanking), while my wife milked me dry. Another time, they traded places.
