Once you get into the lifestyle this is something you should talk about as a couple, what if it happens, what limits are set and so on. We have seen it before, in a hotel room or at a party, no condoms to be found, ok they agree to go bare, just pull out, next thing just this one time ill let him cum in her, she likes it, next time its ok and so on next thing she is always going bare. A few months later you get that frantic text message "Im late" next a picture of a positive test, its not yours you are v safe Ooooops!
