As a junior employee, the woman who joined the company after me suddenly became my boss, while I remained stuck as a low-ranking staff member. Once again today, I messed up and was harshly scolded by the department chief. Seeing my pitiful state, my junior colleague Sumire Kuramoto invited me out for drinks. At the bar, she did her best to cheer me up. "You taught me so much when I first started, that's why I've been able to work hard too... So please don't feel so down," she said gently. Her words pierced my heart and stirred deep emotions within me. Before I knew it, time had flown by, and I'd missed the last train. Since I was alone anyway, I figured I'd just stay overnight at an internet cafe, but Sumire worried about me and insisted, "As your superior, that's an order! Stay at my place and get some proper rest!" Though I hesitated at first, I eventually gave in to her kind intentions and agreed to stay at her apartment. After changing into loungewear, I was shocked to see Sumire standing before me completely naked—no bra, no panties. The sight instantly made my cock hard. Our proximity felt natural, and from that moment on, my heart pounded with anticipation each day. Suddenly, she whispered, "Senpai... can't you tell how I feel about you already?" and kissed me passionately. Surprised though I was, her kiss grew intense, her tongue aggressively exploring my mouth, completely seducing me. Unable to hold back any longer, I finally merged with Sumire. We exchanged fierce, hungry kisses as we desperately craved each other, climaxing again and again. Sumire clung tightly to me, endlessly affectionate. "Let's do it again... Senpai," she pleaded. In the morning, we resumed with wild kissing, her tenderly sucking my cock before impaling herself on it. Overwhelmed by her vigorous thrusting, I erupted inside her. "I can feel your cum filling me up... I'm so happy," she moaned. No man could resist such words. Giving in completely to her affection, I flooded her depths with my cum.
