Even after marriage, I was able to continue thriving at work thanks to my respected superior, Department Chief Sakai. He was excellent at his job, kind-hearted, deeply trusted by his subordinates, and someone I truly admired. However, one night, I discovered an unbelievable secret about him. While staying late at the office to plan a surprise for a colleague retiring for marriage, his true nature suddenly emerged. The Sakai Department Chief I once idealized began frantically groping my big ass like an uncontrollable child. In that instant, my entire image of him shattered, and a new, intimate relationship began to awaken.
