My wife works part-time in the city... I was watching her happily, thinking that she was having fun and that it was good for the household finances as her husband. However, recently, she has been drinking tea and chatting at our house with a young man of about 20 who also works part-time at the same workplace (I later found out that he is a virgin). This is the whole story of how my kind-hearted wife ended up having sex with a younger virgin for the first time.
