Olga:
The best situation is to let her removing the condom
Yes, it should not be up to the husband. If his wife wants to have sex with another man and not use condoms then it should be her choice. My wife had been sterilised some years before we got into cuckolding so pregnancy wasn't an issue, but my request that she use condoms was very soon ignored, as was our rule that she wouldn't go with anyone I knew. Two workmates of mine fucked my wife bareback. One had been after her pussy for years and ended up fucking her on a regular basis, whilst the other she offered it to and he wasn't going to turn down some easy pussy even if he had known me for 30 years. He couldn't believe his luck and took her to his bedroom before she changed her mind!
