College son spies on Mom’s sleepwalking escapades – Part 1

I wiped my glans with the wad of tissues I had grabbed from a box on Mom’s bureau at the last moment and then went to the bathroom to piss. I stood there at the toilet for a while until my erection had dissipated enough so I could go.

That evening, June and Julie worked with Mom in the kitchen to prepare dinner. They didn’t usually offer their help. It was like they were staying close to Mom because Dad was gone. Dinner was amazing and then the twins disappeared to their room to do their homework. They were both good students, vying for valedictorian of their graduating class. Both were excellent athletes too, playing Field Hockey in the fall, Basketball in winter and Softball in the spring. Their softball team was currently undefeated and they were involved in the state-wide playoffs.

I was a klutz, but I was tall. I played varsity basketball in my junior and senior year but I didn’t start. I was always besieged by questions about why I wasn’t as good an athlete as my sisters. I sure would have had an easier time in high school if I was.

That night I woke to a faraway rhythmic banging noise. I held my breath and listened but it had stopped. I couldn’t tell where it was coming from. There were no lights on in the hall or downstairs and I could see that Mom’s bedroom door was shut. As I was drifting back to sleep the sound started up again and I sat up and swiveled my feet to the floor. I expected the sound would stop again before I even got up but it kept going.

I quietly walked into the hallway. The sound was louder and coming from downstairs. I stepped to my parent’s bedroom door, turned the doorknob and pushed the door open enough to see if Mom was in bed. She was. I closed the door and headed down the hall to the stairs. The sound was much louder.

I padded silently down the stairs. I was wearing my cotton boxer shorts and didn’t realize that my flaccid cock was hanging out of the front gap. The downstairs was illuminated only by the digital clocks and timers on the various kitchen appliances and Mom always used an LED nightlight at the end of the bar. The sound was coming from the twin’s bedroom and I stopped at their bedroom door to listen. The banging noise stopped for a moment and then started up again much softer than before. If I didn’t know better, I’d have sworn that the banging was caused by a headboard banging on the wall. That vision caused my dick to harden and push further out through the gap in my boxers. I stood there and listened.

I couldn’t stand not knowing what was going on so I put my hand gently on the doorknob. My heart was hammering in my throat as I slowly turned the knob. Thankfully, it made no noise. I pushed the door inward an inch and just as slowly released the knob. The banging was much louder. I put my fingertips on the door and slowly pushed it open a foot or so and pushed my face into the gap. The room was illuminated by a LED nightlight between their beds. I was stunned by what I saw.

In the dim light, I couldn’t tell which twin was which, but they were both on Julie’s bed. One of them was on her hands and knees with her head against the headboard. Behind her was the other twin pushing her hips against the kneeling one’s ass with her hands on her hips. Their backs were to me. In the illumination from the nightlight, I could tell that they were both naked and the hip thrusting twin had black straps around her waist and the top of her thighs. Under the rhythmic bangs of the headboard against the wall was a soft squishing noise and the kneeling twin was lightly moaning with each thrust of the other.
