Family Get Together

I was 25 married and had 1 child at the time, my wife then 22 family was celebrating her grandfather's birthday and had a get together. So, we went along to celebrate his birthday, his family had 4 children and so me, my wife and her mother then 40 stayed in a motel together sharing a room. The party lasted most of the day and we were you could say very merry on getting back to our room. My wife and I were a bit horny and started showering together, our son was asleep in his cot. We got passionate in the shower and her mother came in and decided to join in our fun. Being divorced and not in any type of relationship at the time she was a bit horny. We weren't concerned about her mother wanting to join in and we all had sex. Even the next morning I again fucked my mother-in-law and didn't take any precautions. As a result of our night of passion my wife got pregnant again and so did her mother. Now 5 years later we all live together and have 4 children and mother-in-law still sleeps with me regularly. As for the rest of our families none know that one of my children is by my mother-in-law. The 2 children were born hours apart and the family thinks they're twins. We haven't told them anything different either, but my mother-in-law take precautions just in case.
