Hubby with Hotwife Seeks Master/Mistress to Train Him

White male, 49, straight, with (white) sexy hotwife who openly cheats on him, seeks dominant
Master or Mistress (black preferred, but white is OK too) to train him, and possibly at a
later stage, possess wife as well.
I've never had any sexual experience with a man, but in the context of D&s,
cuckolding, and presentation, would sexually service a dominant Master
(or Mistress).
Although there is no guarantee, I believe that once I was trained by a Master, my wife would agree to be

possessed by him if Master demanded that I yield
her to him (she is very attractive and hyper-sexual, I guarantee she would be extremely pleasing
to any Master). However, wife would not be interested in any involvement with a woman, sorry. We're clean,
disease free, and would expect same of Master/Mistress.
