Mistress Sarah Kelly, a British dominatrix with a reputation for British sternness, takes her submissive's control to new heights. She uses an electric massage tool to stimulate his nipples, the hum vibrating through his body. She humiliates him verbally, making him confess his desires, as she uses a cane to control his air supply. With his body bound in a scissor hold, she teases him with her stocking-clad thighs, bringing him to the brink of orgasm, only to deny him, over and over again.
