Fucking all night with a colleague with big tits

Mayuki and I joined the company at the same time. She is rapidly advancing while I seem to be stuck in place. But fortunately, although my career isn’t great, I was able to get married. Recently, I've had a lot of work; last night I couldn’t go home and worked through the night at the office, and of course, I haven't showered yet. Today, I'm trying to finish before the last train to get home to my wife. Since this is Mayuki's project, she also came to help me complete it. But she finished while I was still struggling, and by the time I completed my work, I had missed the last train. So today, I won't get to shower again. You didn’t shower at all? You stink too much! My house is nearby. Come over to my place to shower. Because I'm full of sweat, I had to go shower at Mayuki’s house. On the way, we chatted happily together; since we joined the company at the same time, we’re quite close. When we arrived at her house, Mayuki quickly changed into some comfortable clothes. The shorts exposed the big buttocks, and the top of the massive breasts kept provoking in front of me. My little boy quickly swelled. Just today I don't seem to believe my ears. She agreed to let me have sex to my heart's content tonight! And we immediately rushed into each other, constantly having sex all night until the next morning, still working one more round before going to work. Although I wanted to, I didn't dare to ask for it. But when I saw her give me more documents to work overtime, I knew that our relationship would still be able to continue.
