Four capable, arrogant female bosses give their subordinates far more erotic instruction than expected. Iroha wets herself while trapped in an elevator and is blackmailed into sucking her subordinate's cock. A subordinate secretly films Miki having sex with a guard, then uses the video to demand oral sex and keeps escalating. Department head Okae is filmed having an office affair with an executive and forced to suck cock when shown the proof. Manager Yamaguchi is also threatened with hidden footage, yet calmly keeps her superior attitude as she takes her subordinate into her mouth.
