The whole thing started when a neighbor accidentally made a noise loud enough to wake me up. It was late at night and I noticed the house lights were still on through the bottom of the door. 'Odd,' I thought to myself. My mother is never up late.
For some context, my mother had been single for most of my high school days. During my second year at college, she finally made the big announcement that she was a lesbian. It was a shock, but I was happy for her. Hey, it's 2017 and people can be who they want to be. It wasn't much later that mom introduced me to Angela, her girlfriend. They were both roughly the same age, early 40's, and they were the perfect match for each other, despite the fact that mom was a domesticated woman, and Angela was a sporty, outgoing woman. Their differences actually complemented each other quite well.
At this point, it seemed obvious that the two ladies were still out after dinner (or whatever they were doing now), so I decided to go to the living room to make sure the light to the front door was on.
When I left my bedroom and headed down the stairs, I heard something. A faint, unmistakable noise. My assumption was wrong. They were definitely home. But my curiosity was roused by what I was hearing, and for reasons unknown to me, I had to see it. All I had to do was take a few steps forward, down the stairs, and my curiosity would be fulfilled for the night.
There I saw my highly educated and respectable mother on her knees with her face buried in Angela's crotch as Angela reclined on the couch.
My mother was topless. Her sweater and bra were neatly placed on the same couch that Angela was sitting on. From my angle, I could only see mom's pale white back and the side of one of her breasts. And the only thing I could see of her breast was that it sagged while she was leaning forward.
Angela, on the other hand, was only naked from the waist down. Her jeans and panties were tossed on the floor leaving her muscular thighs and vagina exposed for mom's consumption. She was leaning back on the couch with her eyes closed, softly moaning, enjoying the pleasure she was receiving as she ran her fingers through mom's hair.
She opened her eyes to watch my mom's tongue lapping over her labia and clitoris; seeing the control she had over her. I could even hear the slurping and sucking sounds that my mother was making between her legs.
It didn't take long for Angela to catch me in the corner of her eyes and turn her full attention towards me. We were both in a state of utter surprise; I caught them in the middle of a sex act in the house, and she caught me spying on the lesbian act.
We both froze for a brief moment. I didn't know how to react, and by the look on her face, neither did she. And of course, my mother was completely oblivious to all of this as she continued her work on the vagina splayed in front of her. I had a strong urge to just turn around run back to my room, but that would mean making enough noise for my mother to know I was there.
Suddenly, a small grin appeared on Angela's face along with a lustful gleam in her eyes. My watching them was now making her even more aroused than she already was! It was the final act of sexual dominance she already had over my mother. It was as if Angela was getting off knowing that I was witnessing my mother being degraded in such a manner that a woman of her stature should never experience.
She whispered gently to my mother, "That's it. Lick it faster. I'm almost there."
Mom listened as she quickened the movements of her tongue and mouth. Angela's breaths became deeper as she started squirming where she sat. She leaned back on the couch and closed her eyes once again. She was clearly approaching an orgasm. She was cumming, and in my mother's mouth of all places.
Angela shivered for a few moments before her body eventually settled down. She laid there, enjoying the bliss she was feeling, before sitting up and giving my mother a big kiss on the mouth.
With that, I quietly made my exit back to my bedroom.

That night marked the first time that I had ever masturbated thinking about mom. I couldn't help it. I found myself overwhelmed with the taboo of watching her be used for sexual pleasure and knowing she enjoyed every second of it. Before that, I had never seen or heard her in any sexual setting. It was as if she had been sexless and a perfect example of morality. But all of that had changed now and I could never look at her in the same way. And that's what made it so exciting.
It became a dark little secret that only Angela and I knew about. She would wink at me as she kissed my mother, mom oblivious to me watching, as if to tease me, flaunt their love life in my face, and remind me of that fateful night. Her efforts were unnecessary though; the sight of them in the middle of a sex act was something I wouldn't have forgotten anyways.

A month later, news of a possible sudden storm cut short a camping trip my friends and I had been planning. It wasn't that big of a deal, it simply meant that instead of arriving home Sunday night, I would be home really early Sunday morning.
I noticed Angela's car parked in the driveway after my friend dropped me off. I didn't think much of it since it was in the morning and they might have been planning on going out someplace together. But then again, they were expecting to have the place all to themselves, since I didn't want to wake my mother with an early morning text, so who knows what they could have been up to.
I grabbed my things from the car and made my way through the front door, not knowing if I would be walking in on the middle or something or not.
The house was filled with silence as I walked in. Then, I saw her. Angela was completely naked in the kitchen as she came to check on the sound of me entering. We both stood there for a moment with the same deer-in-the-headlights look in each of our faces from this surprise.
I couldn't help but admire her beautifully formed athletic body for the brief seconds it took her to grab the nearest apron and use it to cover herself. She had the perfect balance of muscle tone and curves which kept her feminine appeal. Her breasts looked like perfectly shaped C cups with large brown nipples. Her vagina was cleanly shaven making her large labia clearly visible from where she stood.
"What are you doing here?" she asked in a scolding manner, while trying to keep her voice down at the same time. "Your mother said you weren't going to be back until tonight."
