Mayuki and I joined the company together. She’s climbing the ranks while I’m stuck. Luckily, despite my stalled career, I got married. Work’s been hectic, and last night I stayed late, not showering. Today, I aimed to finish before the last train to get home to my wife. Since it’s Mayuki’s project, she helped. She finished, but I was still struggling, missing the last train. 'No shower again,' I groaned. 'You didn’t even shower?' she teased. 'You stink! My place is nearby—shower there.' Smelling bad, I went to Mayuki’s. We chatted happily, being close from our trainee days. At her place, she changed into revealing clothes—short shorts showing her big ass, a top teasing her huge breasts. My dick swelled. 'Just tonight,' she said. I couldn’t believe it—she let me fuck her all night! We screwed until morning, even squeezing in one more before work. I didn’t dare ask for more, but when she piled on extra work to keep me late, I knew our fling could continue.
