About two months ago my sister was keeping our neighbors house. She was there alone so my cousin came over and stayed with her. My sister would ask me to babysit in the mornings while she was at work, my cousin also worked which left me at the house alone with my nephew. He would be sleeping all morning.
I was watching tv one time and went to the bathroom, I saw a pair of my cousins panties on the floor and got an idea. She brought a bag full of clothes with her so I dug around and found another bag filled with panties and bras. I spread them all out on the bed in her room and went through each of them feeling and smelling them. My cock was hard so I took one pair of panties and wrapped it around my dick and started masturbating. I started sniffing each pair of panties and her bras for awhile and when I was about to come I shot a big load into the crotch of her panties.
Throughout the rest of the morning I would go back and jack off again with her panties. This went on for about a month until her boyfriend came back. I must have shot a load into all but four of her panties, I took those four and two bras and a thong of hers I found.
