My wife has only had my 5 inch cock and her 8 inch thick dildo. My wife is extremely loose for me and I wouldn't have it any other way. I have gained weight over the years and as I have aged my cock has shortened and shrunk up. Meanwhile my wife has had multiple childbirths over the years and has loosened up quite a bit. Needless to say we use her dildo a lot for sex now and when I do get sex now, Its really loose and she doesn't orgasm off of my cock anymore. She knows I love her looseness and asks me if I love her "loose wet pussy". I usually don't last long
