I have been with my husband for 15 years. I have a younger step sister who is 24. I am 39.
Last weekend after kids went to bed she was over and we all started having a few drinks. Me and her starting asking my husband questions. Like who is funnier or who is nicer etc
Eventually it went x rated. We asked who has better tits. He asked us to compare.
Then she asked who gives better head. He asked us to compare again. I went first and he enjoyed it. But then she went and she went to town. And he came all over her tits
I couldn’t help myself but touched myself while seeing him with her. Now it is all I can think about we haven’t talked about it since
