This weekend my wife's younger sister and her husband came to visit us. They spent the weekend with us. Yesterday we all went to a festival and spent most of the day walking around looking. As soon as we got home everyone took turns taking a shower. I had planned to be last but my sister in law was doing something and wanted to wait a while so I went ahead and took mine after my wife and brother in law. The shower is off the guest bedroom so when I went in the bedroom where they had all their things I spotted a pair of my sister in law's dirty panties. Apparently they were the panties she had on the day before.
I inspected the crotch and there were some nice stains from her pussy juice. I took a smell of them and OMG. The odor of her pussy was intoxicating and my dick got hard immediately. Before getting in the shower I jacked off while licking and smelling the crotch of her panties. It made the jack off session something special just smelling and tasting her pussy. As I was about to shoot my load I picked up a clean pair of panties from her bag and filled the crotch with my cum.
After I finished cumming I smeared the cum all over the crotch of her panties and took the hair dryer and dried the cum in them. They were a little crusty but at least not wet. I put them back in the bag and then jumped in the shower. The panties were an odd color, unlike any others I had ever seen.
About an hour later my wife's sister came from the back having finished her shower. She bent over to pick something up and I could see her panties just above her pants waist. It was the ones I had cum in earlier. I got hard again just knowing that my dried cum was getting all over her pussy. I slipped back into their room and found the panties she had been wearing that morning and they were still damp in the crotch. I jacked off a second time smelling and licking the crotch of her freshly stained panties. That woman's pussy turns me on like you would not believe.
I will look forward to their next visit. There are a lot of guys that write here about smelling women's panties. It makes me wonder how many men have sniffed my wife's panties. All I can say is go for it.
