When I went to my friend's house after school, I was excited to see the miniskirt panties of my three older sisters. They knew I had an erection, so they deliberately showed me their panties to seduce me! While my friend and mother were not looking, they pressed their asses against my dick, digging into my panties, and as soon as my dick entered them, I came hard, and after I was done, my two older sisters came to me again in the bath.
