A beautiful aunt with family

I was forced to go to Tokyo to take the exam, so I was taken care of by my aunt, who lives alone in Tokyo. The exam was successfully completed and I was eating my aunt's proud home-cooked meal, savoring the security of being free from studying for the exam...for some reason, my aunt started staring at me... I didn't care at the time, but I never thought that something like that would happen with my aunt...
