This is a Public Service Announcement for the wives, girlfriends, and future exes of the members of the hobby.
You are now discovering that your soon to be ex husband/boyfriend has been playing around with others. I know you will be hurt by this discovery. You will lash out at the ladies of icky and other SHMBs. You will be calling the them cumsluts, whores, tramps, harlots, jezebels, etc.
There is really no need for that behavior. You need to focus your attention on you. What are you going to do? How are you going to confront your soon to be ex? Are you willing to let him weasel out of the mess "he" created? Why did this happen? How did this happen?
Let us focus on the last two questions: Why and How. Even the best relationships are difficult to maintain over the years with both parties contributing. But things happen. Things change.
If you look in the mirror a lot of it comes back to you. If you played the role of cumslut, whore, tramp, etc in your relationship and kept your soon to be ex sated you would not be looking here. Had you had sucked and fucked him several times a week, and I am not talking about just laying there. But actually meet his needs ... Suck his cock with meaning. Get involved in fucking his brains out. Perform BBCR, or occasionally engage in ass play. Your soon to be ex will be drained. He will not have the desire, or energy, to chase some strange. Oh his eyes will wander ... But his pecker will stay at home and have some more home cooking.
So ladies keep the fire burning at home. Up your game. Or welcome to the hobby and be hurt over discovering your soon to be ex has been playing around. It really is up to you. Learn the hard lessons now and remember them the next time you get in a relationship.
Now if you took care of your end of the deal and the soon to be ex still getting strange ... then that is on him and you should dump his dumb ass.
Now show your taint.
