After taking a bath and wandering around naked, I accidentally ran into my sister's friend who had come for an overnight stay. I hurriedly tried to hide, but she got a clear look at my dick. My sister's friend couldn't forget my above-average-sized dick and sneaked into my room in the middle of the night for reverse night crawling! She just asked me to rub it, so we did some frottage, but as we got more excited, she inserted my big dick herself and came over and over!
