Secenerio- It might have something to do with my wife's young adult life as a bar girl in Korea. But she's always been sexually adventurous even when I met and married her at 35. She was the life of the party when we'd go to Swingers clubs.
Now, both in our 50's, adventures have turned more towards MFM, Stag/Vixen threesomes, wife sharing. She likes younger, fit white guys. Truthfully I get more of a charge out of watching her be a slut and getting fucked by other guys. Of course when they finish with her, I move in and reclaim her already cum filled pussy or ass. As I'm fucking her (sloppy seconds) I tell her what a beautiful whore she is. She'll say something cute like, "Yes, but I'm your whore".
