We were at my wife's sister's house and Jenny my sister-in-law asked if I would fix her computer, I said yes. Jenny took me into her bedroom where her computer was then she went back to the party.
I always liked my sister-in-law, she always wears tight jeans and she has a really nice ass. I started to look through her dresser drawers and I found her panty drawer. I started to smell them and rub them on my face, my cock got so hard it hurt, I had to take it out and start jerking off right there in Jenny's bedroom with her panties. I came really quick and I put the panties back under other panties so the cum had time to dry before Jenny would hopefully wear them.
I did steal a pair and have been jerking off with them since. There was also the time I was at Jenny's and she was laying on the couch. My wife and her other sister were in the kitchen talking and I was watching tv with Jenny, well really I was watching Jennys ass because her jeans were so tight. I couldn't stop thinking about jerking off with her panties. What I did next will be another story another time. I am going to jerk off with her panties. Bye.
