Quite possibly but regardless of the cuckolding, they would have divorced for one reason or another given that more than 50% of marriages fail. We’ve been happily married more or less for almost 25 years and we’ve been in the lifestyle most of that time. It’s not about who you cuck or allow your partner to sleep with as much as mutual interest, honesty, good communication and trust.
To all those people commenting "such a lucky husband" ...shut the fuck up with your gay ass, your wife sucking another guys dick really makes you lucky, if you're a dumbass
