We found some female college students on a graduation trip in Hakone Yumoto, the hot spring mecca, and asked them to try out a slightly erotic game at the hot spring resort where they had come to make some final memories as students! You must see the unprecedented high rate of big breasts among the young ladies who entered the bath one after another! All of the busty female college students are over E cup, but will they be able to withstand the embarrassing challenge that awaits them in the men's bath?!
