A few days ago, my wife ran away, and I was down in the dumps. A friend who came to cheer me up suggested I try a dating app, so I did. Following my friend's advice, I signed up and got a reply right away. Half-believing, half-doubting, I responded, and things moved quickly, leading to a meeting. The other person was a gym trainer, so I went to the designated gym, where I had a fateful reunion. Waiting for me there was Yuna, a classmate from high school. Dressed in gym wear, Yuna's sweaty body was too much for me to resist, and I ended up having sex with her in the post-workout shower. When I got home and calmed down, I was consumed by guilt over what I had done. Then, I was called back to the gym by Yuna. I braced myself and went, but the situation took an unexpected turn! Instead of getting scolded, she suddenly kissed me! "It's Ken's fault, isn't it?" she said, forcefully taking my erect cock in her mouth. Yuna straddled my cock, which instantly became rock hard. The gym was filled with the scent of our sweat. Yuna's intense thrusting, unlike anything I'd experienced before, made me cum uncontrollably. From then on, she kept demanding more, and I kept going until my sperm was depleted.
