After meeting in Tokyo and taking the train to the trail, a cute, athletic mountain girl completes a serious climb. Excited by reaching the summit, she begs for penetration and gets fucked outdoors on the ridge, her cries echoing across the mountains. She shows off her favorite hiking gear—and the black thong underneath—before asking not to go home after the descent. They head straight to a love hotel, where she squirts uncontrollably, loses herself in repeated orgasms, enjoys affectionate condomless sex, and gets creampied.
