I will definitely be stealing another pair of my sister in laws panties this Christmas while we all stay together at the lakehouse. I have almost a dozen at this point, I wonder if she even realizes she loses a pair every time I’m around. All sexy little thongs that I like to cum on. I always imagine her putting them back on and getting pregnant again. It would be so fucking awesome to see her pregnant with my baby

A dozen pairs! I'm impressed. I have two pairs of my sister in laws and that took a lot of planning. I must have wanked in one of those pairs 50 times!

Be careful, I got caught in my SIL drawer going through stuff. She was taking a shower and I thought I had plenty of time and I lost track of time and she walked back in the room. First she asked what the hell I was doing and I couldnt think of anything to say. Then she asked me if I was just looking or stealing them. Told her I was just looking and then she gave me the why would you do that. Had a sudden idea and told her that her sister wore boring underwear and I was trying to get ideas for things to buy her. She bought it and then said I’ll try some stuff on for you so you have an idea of how it would look on her. For the next 15-20 minutes she would go into her walk in closet and try things on and then come out and show me while I sat on the bed. After a couple of wardrobe changes I slid over to the left side of the bed and got some quick glimpses of her taking her bra off. Most of the time she had her back to me but sometimes she was standng sideways. The last couple pair I took from the drawer and asked her to try those on and I walked right over to the closet and handed them to her. She kept one hand across her chest and then toldf me these were the last pairs.This time I stepped out of the closet but stood near the doors and just watched, at this point I think she knew I was trying to watch. Got to enjoy this at least 4 more times and I think she enjoyed showing off. To the best of my knowledge she never snitched on me. Pretty sure she just loved the attention. Could have turned out way worse...
