I was around 19 at the time and my sister was in her mid 30s with long legs and I’m guessing 36C breasts which were often braless. Whenever I went to her house I would sneak a peek at my brother in law’s Playboys and Hustlers.
I got so turned on by the magazines that I started jerking off, but in my overly horny state I was looking for some added stimulation. So, I found a pair of my sister’s underwear on the floor. I brought them to my nose and couldn’t get enough of the smell of her pussy. I grabbed a second pair this time out of the hamper and stroked it over my cock.
I wanted her scent all over my privates. I alternated between massaging my balls and the sensitive underside of my cock head with my newfound prize. I then settled on wrapping it fully around my shaft while inhaling the scent of her dirty panties. When I came, I caught all of it in the crotch of her used panties.
I wish I would’ve taken a pair with me to use later at home.
