Twin MOMS Swapping Sons A Breeding Story

It's late at night and because my husband isn't home, my twin sister comes to visit with my nephew . But isn't an ordinary visit. They came all the way here to have sex. Since I couldn't convince my son yet, I had to start having sex with my nephew who was really exci when he heard about me and my sister swapping sons. The sex becomes crazy and we all have sex in the same bed and we get so hot that me and my sister end up being filled with young sperm and eventually impregna. This sex session might have convinced my son to finally accept my offer. Is just sex, isn't it?
