Ero Konbini Tenchou – Episode 4 (EN)

Yui secretly masturbates while watching Shii-chan get violated by Yoshihiro, planning to tease her with hidden footage as usual. But Yoshihiro confronts her gravely: due to economic pressures, she's fired. Devastated—Yui lives with her single mother and can't burden her further—she reluctantly accepts his ultimatum: become his "slave" to keep the job. Swearing inwardly to never forgive him, Yui complies with his lewd demands, stripping her dignity as he greedily ravishes the niece-like JK. She endures forced service tasks, including no-panties restocking under his watchful eye, secret groping, and full-on violations hidden from Shii-chan's view. Despite her resentment and clenched fists of rage, Yui's body responds traitorously to the relentless domination. Yoshihiro's "power" escalates, turning the blackhearted true-diligent girl into a compliant toy for anytime, anywhere creampie punishments on the arrogant JK crew. Miki's presence adds harem tension, but focus stays on Yui's humiliating transition from voyeuristic schemer to obedient slave. Loaded with blackmail coercion, no-panties exposure play, tearful submission, blowjob service, and mind-breaking power-harassment erotica, this finale arc delivers peak JK corruption and depraved manager dominance.
