Hina, a second-year university student, and Tuki, a fourth-year university student, ended up staying at an onsen inn after missing the last train// Their relationship is that of senior and junior in college. With the influence of alcohol, they become close and bathe together ww Hina gets flustered seeing her senior's large penis for the first time... Just washing each other makes this sensitive female college student tremble with sensation... 'Men and women exist to procreate... There is no such thing as friendship between men and women...' The flushed and aroused pair have intense sex in the onsen... They even forget a condom and go raw... Young lust drives them to satisfy each other (゜Д゜) This is truly youthful intercourse
