Helping a Couple Live Out Their Filthiest Fantasies

She and her husband have a very open relationship. They help each other embrace all of their kinks. Over the years they have grown and accepted their (mostly his) limitations. The biggest of which is that his cock just isn't quite adequate to make her cum. So as they have developed sexually he has fallen into his role nicely. He buys her toys big enough to actually make her cum, and doesn't let it effect him. Eventually they learned he much prefers to be a submissive locked in chastity, and to have his asshole fucked while he watches her get pleased. Lately he has been keeping himself in PERMANENT chastity, and really been begging for her to bring another cock into the mix (not just a toy). So, she found one. ME! We met at the gym, became friends, and she explained their dynamic. She is hot as fuck so of course, I agreed to come play. Once I am there she lays out the ground rules for me that both her and her husband have. Mostly being that she is the only one who can humiliate him, and I CANNOT eat her pussy. Everything else is fair game. So as we start her first true hotwife experience, she prepares her husband with his favorite dildo on their fuck machine. Just as I stick the tip of my fat cock in her pussy her husband turns on the machine and starts getting his ass fucked. Pure heaven. I make this new hotwife cum over and over with just my cock, the first time she has ever orgasmed that way. Meanwhile her loving husband is locked away in his cock cage, with his ass getting fucked, just WAITING for some cum to clean up. Well, he gets it. I fill her pussy up, respectfully leave, and they get to finish up their fantasy alone.
