Today I went to my friends house with my daughters and had a cook out. Our girls are the same age but as the day went on I noticed my friend checking out my oldest,12. I knew he had a lot to drink but it became a bit obvious, at least to me. I was getting annoyed and had to use the bathroom. I went inside and was looking out at the pool and noticed his daughter. For some reason I started looking in the hamper and found a pair of his daughters dirty panties. I started to j*** off and ended up c****** all over her panties. I felt much better about the situation.
