I’m 17 and my brother is 13. We pretty much grew up together. If one was in trouble the other was involved in someway. We share the lower part of the family house with two bedrooms , bath and a game room. Last night We had a movie on watching the Addams family. Some days he gets hipper and acts crazy. To calm him down I’ll let him lay next to me. Last night was one of those day’s I laid down on the couch and let him lay on top of me. That’s seems to be his safe spot in the world. For some strange reason he gott’n curiously wanting to cop a feel of my breasts. He started gently rubbing one. I looked down and gave him a serious look . He stopped for a few minutes but returned. I said to myself ok lets see how far he wants to go. I opened my night robe. He instantly took a breast and started sucking away. Few minutes later i started to enjoy it. I took his hand and placed it on my other breast and took him to gently rub it. Before I knew it, I had a hand placed on the back of his head pressing down on my breast. I’m really enjoying it. I even took a hand and slid it down and started rubbing myself. Few minutes later my poor little brother was dry h****** me and released He thought he had pissed in his pants. And told me about it. I replied no that’s called a pre e********** and giggled . He returned back to sucking on my breast again.
