Aiden and I have a bit of a #8230; well, secret relationship. Mom has no idea what we do when she s gone. We were eagerly waiting for her to get ready and go to work, but she was taking forever. She said she wouldn t be back until about five, so after she was gone, Aiden and I did what we always do. I unbuttoned his pants, and stuck his hard cock in my mouth. I ran my mouth up and down his shaft, and joked about Mom catching us. It s such a turn on to know that I can make my brother feel so good. After just a few minutes, I started to feel him REALLY throb, and I knew I was doing a good job. Little did I know, Mom forgot her car keys, and barged right back in! It completely caught me off guard. #8220;! FUCK, FUCK! #8221; I ducked my head underneath the desk, and Mom was utterly shocked at what she saw. My brother tried to play everything off, saying that I dropped my pencil, but we both knew that she had caught us. I was so embarrassed that I just kept my head down, but she walked right over, and stood over the desk. She noticed my brother s hard cock immediately, and then asked us how long it had been going on. I didn t say anything, but my brother lied, saying it was our first time. She knew he was lying, and then directed her attention at me. I told her I didn t want her seeing me like that, but she didn t care in fact, she had the intention of punishing me by making me suck his cock in front of her.
