A strict, late-thirties female boss who is still single. When a package addressed to her is opened, it's a clitoral suction vibrator called 'The Sucker'! It turns out she's a frustrated woman who loves toys and is obsessed with masturbation, and she accidentally had it shipped to her office instead of her home. Taking advantage of her request for secrecy, her subordinate begins suction training! The intense, clinging stimulation makes her knees shake, and as her exposed, sensitive clit is relentlessly played with, she reaches a humiliating climax, soaking herself in squirt. Furthermore, she is made to wear 'The Sucker' even during work, causing her to repeatedly reach orgasm and leak juices wherever she is, turning her into a complete lewd female.
