I grew in a conservative family where you would never hear the word shit around the household. When I got eighteen, my family threw a fantastic birthday party for me. Although, the party was private, it changed my look at things and at my own family. Other celebrations were events to remember as well. Finally, I had a great marriage.
Newly married couple moves to New York, where the husband has been transferred. His step-son and niece are living in the same household enjoying sex with each other, while the husband and wife have sex with each other and reluctantly swing with the husbands boss and wife. The whole family gets together for a nice 'house warming'.
After the Bad things in life, it can start to get better. What is it 'They' say, jump from the frypan into the fire.(Who is this 'They' again) Of course, you would have to have met Sil first in order to better understand why a man could do such a thing. Sex is only implied but knowing Sil, who knows.
