Looking at panties is a daily routine! I was waiting like usual, but it seemed like the older sister was showing me her panties on purpose... Then she came closer and asked me, "Want to see more panties in a place where no one is around?" I was so excited to see the older sister's panties up close! She escalated things even more, asking me, "Want to touch them?" Finally, it developed into sex! I, a peeping tom, was promoted to a sex friend! I took a big step towards adulthood!
