After a dirty threesome with two male slaves I have the pleasure of sharing a bubble bath with Mistresses Sarah. After being invited into the bath, she kindly helps me wash the cum off my small perky breasts. I return the favour by gently washing her back with bubbles. My moment of pleasure stops there as I must be punished for my slutty behaviour. Bent over on all fours in the bath, Mistress gives me a wet and soapy spanking. Interludes of pussy teasing and nail scratching across my round butt are enjoyed by myself but only for brief moments as the harsh spanking continues until my butt is bright red and sore
