Was taking care of my neighbors dogs at their house when I found some things.
I was just sitting in their house taking care of the dogs when I had to go to the bathroom. While I was washing my hands I saw a bra on the floor, I knew it was the moms because it was big. (I have fantasized about the mother and daughter in a threesome with me many times).
Curiosity got the best of me and I looked at the size and it was a 38C. I got super horny and found a pair of silk panties of hers. I pulled off my pants took the panties and jacked off with them. I jizzed in the toilet put the panties and bra back and went back to taking care of the dogs.
