I snuck out of school early the other day and went home. I quietly entered the house because I saw my dad’s car there and didn’t want to get caught. I heard something in his room so crept to see what it was. I saw my little sister naked and riding him, she’s 14. I went to my room and jerked off. I want to talk with her about it, but don’t know how. I now know why they spend so much time together.
