My wife and her sister swap husbands on visits... we live 2 states away.. usually the first night we keep it seperate , one couple will stay at the house, and the other go to a hotel and anythig goes. The second night we all play together @ home. Her sister (below pics) is 34D compared to her 34A.
Variety !!!
I always notice she is really wild and anything goes when we're alone, but when we are all together playing she is more reserved.. supposed, we are the only people they swing with. My wife said that her hubby seems to be the same way with her.
