Is it something and nothing, my husbands sister was staying with us for a week, it was after lunch I was on my way out shopping, I shouted ime going now, I was by the front door I could see through to the kitchen my sister in law was sat at the table finishing her lunch, my husband was stood talking to her when he undid his pants pulled them down his underpants as well and rearranged his clothing I have see him do this in front of me whish is ok, but he fully exposed his private in front of his sister with a semi hard cock, there was no reaction from her at all, my brother has never done that in front of me, I am only speaking of my own experiences, comments please.
