Sister in laws panties
My wife's sister was out of town and asked me to stop and check on her dogs on my way to work. I stopped and checked on the and had to use the restroom before I left. I noticed her pile of laundry and a pair of panties on top. I picked them up and could tell she had been really wet when she wore these. The smell was amazing. I got rock hard instantly and it didn't take long to not for me to shoot a large load into the panties. I put them back where I found them. It was fun but I hope she doesn't notice when she does laundry.
