So I (M 51) have always had the hots for my wife’s sister (f 48). Always trying to catch a peek of her etc. Never thought in my mind anything would ever happen. She’s a very conservative, typical soccer mom of 3 boys who looks great but you think she would just have vanilla sex so I don’t know why I was crushing on her.

Anyway, we are both in nursing and decided to go to San Diego for a conference we both had interest in. Since we live in different states we would meet at the conference. I have always used conference as a place to fuck other women but I was going to have to be discreet obviously. Get to hotel and get to room. Meet her at the welcome happy hour and we chat but also find other people to chat with. Since we have been traveling all day we both call it a night early and go to our rooms.

Next day is conference and we meet for breakfast and pal around together at the conference. We meet a bunch of people through the course of the day and we all decide to meet up later and get some food and drinks. I thought this was awesome cause there was shot blonde I wouldn’t mind getting into.

We go to dinner and have a great time. Drinks flowing. We walk around gaslight district and find a bar that’s playing music and we can dance. I start chatting up the blonde and then hit the dance floor. But much to my surprise the SIL is grinding on some young guy. Liking what I’m seeing from her and knowing she’s had some to drink I let it go. Didn’t really get anywhere with blonde and SIL grabs me and we start dancing. She starts grinding on me and I’m like wtf why not. Next thing I know I look down and her and grab her and kiss her, cause again why not. Break the kiss and she grabs my hand and says let’s get out of here. Walking back to hotel kissing and feeling each other, the whole way my mind is blown.

Get back to hotel and it turns out she’s not the conservative mom I thought she was. Was a crazy and and long long night of fun
