Being paid to be spanked for academic research into corporal punishment isn’t easy money for Belinda Lawson and Helen Stephens at The Institute . They’re surprised at the increasing severity of Earl Grey’s swinging right arm! Bent bare bottomed over his desk, Belinda can’t resist provoking him as a two-tailed tawse lashes across her buttocks 25 times. Helen is bent over alongside her, bottom bare, but has to hold her wrists when Belinda struggles. Epic slow-motion butt-rippling, cheek bouncing replay of every stroke!
