Playing around

I went to a family wedding with my wife 33 and her sister 30, a cousin of there was marrying. We had great time, and the children were back home with my parents and the venue was right next door to our motel. We had a fair bit to drink and next morning I awoke in bed with sister-in-law. My wife wasn't anywhere I could see, I couldn't remember what happened after getting back to our room. I was starting to worry when my wife came out of the bathroom totally naked and got back into bed with me and her sister. We had sex and her sister awoke while we were fucking and joined in making a threesome. Now 5 months later my wife is again pregnant and so is her sister who has moved in with us and shares our bed. Great Wedding.
