The sister-in-law 's panties

My sister-in-law Luana, 21 years old, blonde, 1.70 a body in a very nice shape and Cute, owner of a pair of breasts and a big, pointy ass.
I've always had a crush on her, but I've never done anything but look at her big bitch.
Once, we were invited to dinner at her house, as it had been a long time since we had met, and my wife accepted at once.
We stopped at the market, bought beer and went, arrived at the appointed time.. 19:30
My brother-in-law welcomed us, Fabricio invited us in, we sat down and he said that Luana was in the bath and would come down soon.
We open the beer, we toast, and we start drinking...
Soon my sister-in-law comes down, with a pair of shorts, and a regatta, she was beautiful and smelly as always.
We drink and we talk and we laugh.
Soon I felt like going to the bathroom, so I excused myself and went.
I got to the bathroom, and I saw on top of the toilet, Luana's panties, a red panties, small...
With a thread in the back and a small one in the front...
Seeing those panties gave me a hard-on, my dick got hard in no time...
I made sure the door was locked, I grabbed my panties, they were still warm... and I smelled... a nice smell.
I pictured her wearing...
How hot it would be, I smelled... I licked that hot panties... I pulled my dick out and I rubbed that hot piece of clothing... on my dick and I started a hand job...
Imagining my sister-in-law wearing, my dick throbbing with a boner...
Until I had fun....I looked right at the part where I was in the bouquet..I had a lot of fun....
I cleaned myself, put my panties in the corner, washed my hands and walked out.
I came into the room, saw them laughing and joined them..
Relieved and satisfied...
Anybody else in there ever done anything, hit a hot hand job on some piece of clothing...
