Your boss motivates you in a special way. She keeps your cock & balls locked in chastity with the reward of being unlocked & milked once a month IF you meet all productivity goals. It means you end up working long hours & much harder than you ever thought possible, but you get so horny that you'll do anything to cum. Your boss isn't very nice about your monthly milking, she degrades you, ignores you & does little to help your orgasm along. She doesn't really care if you cum or not. She increases your goals for next month & it's unfair, but you'll keep coming back for more because she holds the key to your chastity device.
