My wife has enjoyed a decades-long incestuous affair with her youngest brother. When we got married, she was trying to break off that relationship, however KK was basically addicted to his cock. Her last experience with her brother, at least what was planned to be their last fuck was the morning of our wedding day. I unknowingly partook in sloppy-seconds on my wedding night. The most brutal part was that KK was not on birth control at the time - she rolled the dice, chose to fuck David bareback, having decided that if she got pregnant, she'd have a fallback excuse...
It would be hot as hell to see a bride cuckold her groom IRL, fucking wedding guests, the best man, photographer, throughout the event, and into her wedding night, while her cuckold husband is left to his own devices.
