``Senpai, I'm drunk...'' I missed the last train after driving my drunk junior to her home. - ``Are you going to stay the night?'' I, who have a boyfriend, was shaken by the words of my junior who was so loose and arrogant that her breasts fell out defenselessly. - Finally, the two of them snuggle together, take a bath, and have sex over and over again. - ``Maybe I like my senpai.''...I'll forget about my boyfriend for today, and after taking off my clothes, I'll spend all my time having sex with my big-breasted junior.
