An interesting subject, if i may refer to the original post, i personally think his wife has been very brutal in marking him on his abilities, thats something i would not have liked being humiliated in this way and know my wife would never do this. To me my wife prefering other men sexually to me tells me what i need to know anyway without her saying it, its not my size but my experience that failed me, add in her desire to explore her sexuality meant as she has admitted i was always destined to become her cuck husband. One of her "wants" on her tick list of boyfriend/husband was that he wasnt a player and then married she found the disadvantage to this.
She will loose respect for him as a man and lover and obviously already has done hence the marking.
Its a dangerous game he is playing and he should and must know that, good sex is very emotional and mentally stimulating for a female so relationships and love is easily formed between the pair, certainly on the female side more than the male one. Could he stop her now, thats a definate NO.
My wife as a cuckoldress fell in love with two of her lovers and it was her decision to stop the relationship to save her marriage, the first was a secret affair, her second affair, hence my true cuck status, the second i knew about, enjoyed watching and encouraging her.
She should be involving him which she appears to be doing which is good, i have rarely cleaned my wife after she has been cum in, she doesnt want this and neither do i. Having semi feminized and locked me she prefers to bring me her cum socked knickers and for me to wear them.
Having commented on his lack of a dick size she will not see it a threat that he will leave her for another women but will she leave him for her lover, thats a possiblity.
