Sat on by an idol girl in black leather pants. Drinking down the sweat of a bratty maknae right out of her used latex catsuit. Letting the idols slap you to take out their anger at jerky paparazzi. Are these things you fantasize about? If so, welcome to your new job S&M Entertainment.

Yuna Yu was the hottest (and meanest) girl at your university. You’ll never forget how she made you her slave for a year, forcing you to appear in her degrading fetish videos . When Yuna graduated, you thought you’d never be subject to her humiliations again. You were wrong. Unbeknownst to you, Yuna was hired as a young executive at S&M Entertainment, the hot new K-pop label, and she already worked her way up the ranks. Every day, a new scandal involving one of the label’s starts hits her desk that she has to respond to. Her toughest challenge?

Finding competent and obedient servant boys to keep the idol girls happy. No band is harder to please than Sugar Rush. The cute “girls next door” of Sugar Rush are nothing like their curated on-air personas: Baby Cleo: A leather-clad tyrant with impossible coffee orders and a very heavy boot. Mina: A cold goddess who dreams up sadistic punishments for your aching balls. Jiyu: A smart mouth with the right insult to pierce your soul—and a wad of spit for you to swallow. Bomi: The bratty maknae who always gives it to you the worst, whether sitting her pretty leather-clad ass on your face or making you lick her sneakers.

When Yuna sees your humiliating application video in her emails, she knows just who she needs: you! You take center stage in this scintillating second-person femdom erotica, which builds on the story of Worship Yuna (Parts 1-12) and Yuna’s Graduation. Behind the scenes, Yuna is battling useless old male producers to launch a dominant new girl group concept. She’s secretly engineering your humiliation to prove her theory: that a "Ballbusting Bitch" is the ultimate K-pop evolution.
