In order to take the university entrance exam in Tokyo, I ended up staying with my uncle who lives in the city for a while. My wife, Mako, is a graduate of a famous female university, so she was supposed to be watching me study. However, I saw Mako-san's sophisticated sex appeal and high-class underwear having sex with my uncle, and as a country boy and still a virgin, I was unable to study. Then, Mako-san came up close to me and pressed her lips to me, saying, "You saw me yesterday, right?"
