[MF] the first time I saw my SIL semi naked

So I’ve told a few people on reddit that messaged me about my experience with my SIL (wife’s sister) after my first story I posted. So here’s a story about my first time she teased me.

My wife and I decided to hang out her sister for the day. We all were trying to figure out what to do for the day. So my sister in law mentions, she’s interested in going shopping. My wife wasn’t to keen on going to the mall, so we decided that we should go to target because she wanted to spend less money and time.

We walk into target, my wife said she’s just gonna look at leggings and a few t shirts. I tell my wife she should try some dresses for the summer season. My wife gave me a hard no, but suddenly My sister in law comes in and said she’ll try on what ever my wife doesn’t.

I pick out a knee high dress with kind of a halter top to it. My sister in law had a few other dresses in my her hand and we all head to the dressing room together. My wife goes in the dressing room and sister in-law gets a room across from her. I wait outside and look through Instagram. After a few minutes go by, I hear a door open. It’s my sister in law. I see her come out in a night gown / some sort of see thru dress! She ask me how it looks on her. I could see her nipples and panties ! My heart totally sank and my dick got hard instantly. In worry that my wife my come out and see what her sister was wearing in front of me. She begins to twirl and ask me how it looked on her. In a long pause but assuring, I told her it look nice. It would be great to photograph her in. She looks at me and blushes and gives me a small head tilt. It was soo fucking hot. My heart just was racing. She then turns out and skips back to the dressing room and I just look at her ass jiggle back to the dressing room.

And just by chance, my wife calls my name and ask me to grab her another size for leggings and just missed me seeing what her sister wore for me.

But this was the start of my sister in law and her vouyerstic / exhibitionist tendencies around me.
My sister in law and I continue to do this ever time we would go “hang out” or go shopping at “the mall” she would always wear what I tell her to put on.

I miss those days..
