After a long day, I found myself with an overwhelming thirst. Making my way to the kitchen, I realized that the water dispenser was out of order. With nowhere else to turn, I headed to my stepbrother's room, hoping he had a bottle stashed away. As I walked in, I was caught off guard when he suggested we spice things up and turned the water girl fantasy into a steamy reality. His fat cock was the perfect thirst quencher, and I eagerly took it in my mouth. The taste was incredible, and I soon found myself craving more. We delved into a passionate encounter, with him fucking me relentlessly until he filled me with his hot load. It was the ultimate satisfaction, quenching my thirst in the most satisfying way possible.
