My bf and I often have affairs with each other. We will send smutty text messages and emails etc. When we have sex, we have a little role play where we talk dirty to one another and say things like "I should not be here, my husband will be wandering where I am, I have to go and pick up my kids from school" He will say "My wife is too boring and frigid, you get much more eager and wetter than my wife" I personally would never realistically have an affair, I can see why people do or would because it is risky, illicit, exciting, they are not getting any attention at home etc ... then there is going home to your boring husband with another man's spunk seeping out of you, soiled panties and your lover's smell all over you etc. If you are a man with a mistress, you are going home with another woman's juices around your mouth or scent around your dick ( I had better calm down there! lol ) Do you do the same with your SO?
