Good question! Difficult to say, bear in mind that it was hubby that got me into this, and I wanted to keep hubby involved and get deeper in it himself. He wouldn't watch at first, then he did, he cleans me but is a reluctant cuck. I knew that he wanted to do more so I've pushed his limits, like mine have been pushed.
So, I wanted to feminize him fully, especially in our private life. Hormones, removal of body hair, little breasts, even make up and dressing at home.
The two things stopping the full change was hubby is a manager at work, and our sons might be confused. Our sons, however, have accepted me going with other men so I don't think they would have been too concerned.
If he does any more changes it will be more private, he's already agreed to a cage and pegging, we're talking about operations on his penis in the future, no one will see that.
