I couldn’t believe that my sisters friend Megan was teaching her how to rub off h****** her pillows. They had left the bedroom door open a touch and I couldn’t ignore what I saw with a glance in passing. I hadn’t yet thought of my sister “That” way. She was only 11. I was 16 and messing around with a lot of girls since I was 13 mostly older but some younger than me. Knowing I should move on I had to watch. Then I had to join the two naked cuties. They were totally embarrassed but I calmed them down quickly offering to get naked with them. They had a zillion questions. We talked and touched and kissed until it was time for lunch. They both had small comes h****** the pillows while I watched and touched them and I showed them how I stroke off and ejaculate. I had shown them how to rub off and how girls like to trib with each other. That was a lot of fun and they had better orgasms. I took us to McDonalds, their pick, and we continued to discuss s** most of the time. The girls were very h**** and squirming in their seats. Back home we were naked before we were on moms bigger bed. I did them orally, which made them both come like crazy and they gave me a double b****** combo and ate my c** they had tasted earlier. We had Megan for the week since school was out and her parents went on a second honeymoon. This was pre Covid and we still have s** often. They introduced me to a whole new age bracket of pretty, and curious girls who were h**** like them. Very interested in learning about s** with me and their girlfriends. The young girls love c*** and p**** play!!!!!!!!!!!!
