Staying overnight at my uncle's house in the countryside, I couldn't fall asleep and kept my eyes shut. Suddenly, my cousin Sakura, who's always kind and adorable, appeared out of nowhere and started giving me a reverse cowgirl surprise in the middle of the night! Her gaze was strangely lustful, as if deliberately seducing me. Thinking I was asleep, Sakura began grinding hard on me, thrusting her hips wildly as if trying to rip my cock off from the root, selfishly climaxing again and again in a dominant cowgirl position. Completely lost in pleasure, she rode me relentlessly while I pretended to be unconscious. That unforgettable night still lingers vividly in my memory.
