When I was an MS, there were 2 elders who during their shepherding calls were asking couples if they were having oral or anal sex. You know cuz doG hates that. Where a mouth or penis goes is very important to him.
Well, word got back to the P.O. who was a good guy, and shut that down quick.
It seemed that one of the brothers was out trolling for potential sisters to screw, while the other one had other issues. The first elder wound up shacking up with a sister, got divorced, moved away, and sadly came to a bad end.
