As I lay in my bed slowly beating my meat with images of my girlfriend in my head, I heard a small sound in the hallway. My hand instantly froze as I darted under the covers. The sound in the hallway seemed to be coming from the doorway of my sister Claire’s room. As I listened, it started moving down to the end of the hall. Then I heard a door open. I figured my sister had probably gone to the bathroom. I lay in my bed, waiting for her to go back to sleep before I started whacking off again, but after 10 minutes she still hadn’t come back.
I walked out of my room towards the bathroom, but as I passed my mother’s room (my mom and dad had gotten a divorce 3 years back, and she got full custody of my two sisters and I) I saw that the door was slightly ajar. My mother’s door was never slightly ajar, and it was always locked. As I peeked into the room, expecting to see my mom sleeping, I instead saw Claire kneeling on the bed with her head thrown back.
There were soft moaning sounds coming from her lips, then she arched her back and let out a louder moan. It was then that I saw my mother’s head right under Claire’s pussy. As I realized what was going on, my cock started to rise of its own accord. Within about 3 seconds, I had the biggest hard on I had ever had, and I was getting it from watching my sister and my mom! Not fucking my girlfriend.
As I sat there with my raging hard on my right hand slowly slipped down to my cock and started beating it while Claire lay on the bed with my mom kneeling above her. My mom was moaning quite loudly as she approached her climax. I heard her ever so softly calling Claire’s name. As hear voice slowly began to rise in pitch, her hand shot out to Claire’s clit and she started fingering it! Her hand flew along Claire’s clit as Claire shot her tongue into and out of my mother’s pussy.
This was too much for me, and as I sat there, I felt the cum starting to rise in my cock. I hurried to the bathroom where I jerked myself to a climax thinking about my sister and mom. After I had cleaned myself up with some tissues, I started to walk back to my room, when I realized that my mother’s door was still ajar. I took a quick peek and saw that now my mother was over at her dresser.
