when we first started the sharing thing, we said no kissing but seeing my wife soooo turned on . I knew it she couldn't do it. she had her tongue jammed in his mouth. She told me she didn't even realize she was breaking the rule. I realized I enjoyed watching how turned on she would get. she would never swallow my cum when she went down on me. she always spit it out. The first time with another guy (my buddy) she sucked him dry and he told her her to not loose a drop and she swallowed every bit. So no kissing was not going to hold up. glad it didn't.
