It was a sunny Saturday and I was walking to my friend, Tim's place. We are both high school seniors and usually spend the weekends hanging out at his place, playing video games and such. His mom doesn't mind me being over so much, actually I think she enjoys having the extra company. Tim's mom, Maria, was always nice to me. Since she was like my second mom, I did not think of her in a sexual way. But I guess she is attractive for her age. She has some extra weight on her but not enough to call her fat. Just enough to have a curvy body that can make her look good. I have seen her go out with men over the years, some of which I see leaving the house in the wee of the morning. One of these times, before Maria left for her date, the shirt she was wearing showed a tattoo of a rose wrapped around a sword between her breasts. My guess is she got it when she was still a teenager, a bit of a rebel I guess.
Anyway, I arrived at Tim's place and let myself in as usual. Maria was sitting at the kitchen table reading the newspaper and she looked up when I walked in.
"Hello Austin. There are some pancakes there, feel free to help yourself."
"Thanks" As I helped myself to some pancakes, Tim came down the staircase and joined us. The three of us chatted lightly till I was done. Then TIm and I went downstairs to the TV and left Maria alone.
A few hours later Maria joined us and the three of us played video games together. I always liked that Maria enjoyed playing video games with us. Made her feel more like a friend than a friend's mom. Eventually Maria got up and said she had a date tonight and had to get ready. Tim and I decided to quit the games and watch a bit of tv. After about a hour of watching stupid comedies, Tim suggested to watch a movie instead.
"Put something in, but first I have to take a piss." I said.
"Sure, just use the upstairs one cause the main one's plumbing is acting up. The plumber is coming tomorrow."
Nodding I walked to the stairs to walk upstairs. When I reached the top landing I noticed that Maria's door was closed. "Must still be getting ready for her date" I thought. I turned to head to the bathroom and as I approached, I saw the door was closed except for ajar. I motioned to open it all the way to enter it, then stopped. Through the crack of the opening I could see the mirror in the bathroom, In the mirror I saw the reflection of Maria sitting on the side of the bathtub. I couldn't look away because Maria had her shirt off and was in the middle of fingering herself. I watched as two of her right fingers repeatedly slammed into her vagina while her left hand played with her tits. Her head was back, eyes closed and mouth open in a silent moan.
I instantly had a hard-on and had a strong urge to rush in to the bathroom and replace her fingers with my now fully erect cock. It was as if my feet were super glued to the ground, I could not move. I stood outside the bathroom door watching the reflection of Maria getting closer to orgasming. As I watched she inserted another finger into her dripping vagina and pounded it harder. Her other hand tugging at her perky breasts. I couldn't ignore my throbbing cock anymore, and unzipped my pants to start stroking my dick. Just as I started to stroke though, Maria she started to squirm on the spot and finger fuck herself harder. She fell off the side of the tub and squirmed on the bathroom floor with an orgasmic face. As she came, even though her mouth was open wide, she only a small squeal, and I'm sure she held back since Tim and I were in the house. Looked like it was not her first time keeping quiet.
She started to get up from her spot. Since I still had my hard cock in my hand I quickly, and hopefully quietly, shoved it in my pants and walked to the stairs. I descended them as quickly and quietly that I could manage and retook my seat on the couch.
"Where were you man?" Tim asked. I tried to hide the tent I still had and answered
"Yeah sorry, I took longer than I thought I would."
As the movie played, I could not concentrate on it but rather thought of what just happened. My head was still buzzing at the fact that I just saw Maria, practically my second mother, masturbating. At first I felt ashamed for liking it but seeing her body shake with ecstasy made me so horny that all other thoughts were vaporized.
Later, Maria came down the stairs dressed for her date. She was wearing a low cut shirt that showed her breasts and a skirt that ended just before her knees. I only glanced her way cause I felt guilty if I looked at her any longer. Like she would know what I saw if my eyesight lingered.
"Night boys, don't wait up" She said, giggling.
"Night" Tim and I said back, I said it a little quieter. I could tell she was giving me a look in my peripheral, but I did not meet it. She soon left when her date arrived.
Tim and I continued to watch the movie, but I could not concentrate on it. My thoughts kept travelling to the upstairs bathroom and how much I liked what I saw. I decided to go home early even though Tim suggested I stay the night. For some reason I did not want to see if Maria brought her date back home so I declined. I had trouble sleeping that night as the image of Maria's quivering naked body did not want to leave my head. I ended up masturbating to the image and fell asleep instantly once I came.
