Yuko, whom I met through a dating board, had an intense masochistic side contrary to her outward appearance. When tied up with rope, her previously cheerful and lively personality completely transformed into something entirely different. She reacted intensely to anal stimulation, unable to withstand even the sensation of candle wax. During enemas, she displayed an expression mixed with agony and pleasure, groaning loudly "Ughhh!", as the anal plug shot out and feces gushed out thickly—an undeniably erotic scene.
