One day, I received a call from my senior asking me to watch over her pet. When I brought her home, it turned out to be a beautiful woman named 'Yui' with fair skin and black hair. Apparently, her senior's "pet" was her, and she enjoyed being fucked hard with a big cock. Even though she pretended to be reluctant, she was actually thrilled... I ended up taking care of her as instructed, despite not knowing much about her. When we were alone, she was quiet but affectionate, acting like a spoiled child. Her tsundere attitude gradually drew us closer, and we started seeking each other out repeatedly. We engaged in toy play, intense creampie orgasms, deep-throat blowjobs, morning blowjobs, and consecutive creampies in a three-way. This was a two-day cohabitation experience filled with intimate moments with a beautiful, quiet, and pale-skinned woman.
