One day, a beautiful strange woman was cleaning the stairs of an apartment building... and surprisingly, she was wearing no bra or panties! Her name was Rabu Saotome, and she and her husband had apparently moved next door. We didn't even get to say hello, and on another day, an envelope addressed to Saotome was accidentally posted in my room. Is this someone's idea? A neighborhood relationship with a wife full of mystery and eroticism has begun!
