My husband and I are starting to get into cuckolding.
I have found a really nice hot guy to relax with and he is up for it. He knows I am married and my husband wants me to relax with him.
I have not told him yet that I am cuckolding my husband or that he is in chastity. How should I tell my boyfriend so he is not freaked out and how much should I tell him? Please Help!!
You don't have to tell your boyfriend anything more than you are willing to have sex with him.
Your boyfriend already knows that your husband knows about him and is ok with you "cheating".
If your boyfriend is curious, he'll ask questions, and you can answer them.
It might be a long time, or never, before your boyfriend is comfortable with including your husband in any sexual activity.
