I held in a silent moan as I worked my cock, watching intently through the door at the sight before me. My stepmother was currently leaned back on her bed, her top over, her big tits exposed, with her hand down between her legs, her panties pulled aside as she masturbated while watching something on her phone. Her face was filled with passion and need.
I was watching through the crack in her bedroom door, which I could just barely make things out through. My cock was so hard as I worked it.
My name is Dennis and I'm twenty-three. My stepmother's name is Alice and she had married me and my sister's dad about two years ago. In usual fashion me and my sister hadn't taken well to her. Especially my sister, who was then only sixteen. But things had calmed somewhat. We tried for my dad's sake. But it wasn't easy.
What's going on right now was a recent discovery. I'd come home early from work one day and heard the unmistakable sounds of a woman moaning in a sexual manner. Coming upstairs I'd come upon a similar sight to what I'm currently jacking off to right now. My hot stepmother masturbating.
It turns out she was a regular baiter, if you know what I mean. My dad works long hours in an office so she's alone as often as not. So apparently Alice took care of herself regularly. She seemed to do this several times a week by my guess. I had no idea until my accidental discovery.
Not that I objected.
I know, I know. I'm a total perv for spying on her special moments like this. But I'm a guy, so what do you expect? Besides, she's my stepmother. And she's really hot. We can thank the porno industry for the whole stepmother-stepson thing being a fantasy. It's not right by any means.
But by God is it so hot. In her room Alice was nearing the end. Her breath was heavy, which made her big boobs heave. He hand was moving fast and hotly. At the same time, I was getting there too. Stroking my hard cock fast. I too was also almost to the end. No sooner than I had thought that, she leaned back on her pillows. "Oh God, yes, fuck, fuck me, yes!" she moaned as her body convulsed while she orgasm'd. That sent me over the edge. I clenched my teeth so I wouldn't moan loud and alert her, then I used my free hand to hold up the paper towel I had brought with me and shot my load into it.
As she laid back and recovered, I stuffed my dick back into my jeans and left, making sure to throw the paper towel away in the trash can in the kitchen. Then I went outside, waited a few moments, then came back in loudly, wanting to be heard. "Anyone home?" I called.
"Hi Dennis!" came the call from upstairs as Alice was now likely fixing her underwear and putting clothes on. I went to the trash can I had just deposited my wad into and began changing it. It didn't really need to be changed but I did not want her or my sister Lila to find it.
Alice came down. "Thank you for taking out the trash honey!"
"No problem," I replied. I deposited the trash outside in the can, then we chatted about our days. I work at a large book store and sometimes worked as an Uber driver. After we exchanged small talk, I went to my room and relaxed.
I don't know what would ever happen if she or my dad found out I spied on her and jacked off to her. Which was why I was careful and didn't do it every time. But my dad is currently on a business trip for the entire weekend. When he's away, her masturbating tends to become daily as she uses it to think of him or dispell and thoughts of cheating. I'm currently single and have my own needs obviously. And since she doesn't know, it can't hurt her.
Or me.
I hope.
I sat up as I heard the sounds of my sister coming home and angry voices from downstairs. I got up and went downstairs to see what the problem was. Contrary to my big titted blonde stepmother, Lila was smaller, brunette, pretty flat chested, petite and perpetually young looking. I have the same brunette looks but inherited my dad's height at 6'2. Lila was barely 5'3.
And she was currently arguing with Alice.
This was also nothing new. Alice tried her best with Lila but my sister was a teenager when Alice had entered our lives. Lila had been much younger when our father remarried and took it much harder than me. Me being older had helped me temper my resentment a little bit more. But Lila, full of (at the time) sixteen year old girl drama, had not taken it well. And now, two years later, things were still pretty rocky between them. Especially since Alice did not care for Lila's attitude, which was what you'd expect from a teenage girl. Lila was not yet out of high school and her grades were not great. Thus the arguments.
"Do you even want to graduate?" said Alice.
"Does it fucking matter?" asked Lila in return.
"For your future it might," said Alice.
"Dumbass over here didn't go to college," said Lila pointing to me.
"Don't use me to make your points," I said to her. "You and I live very different lives, sis."
"So you're taking her side?" she snapped at me.
"No, I'm saying do not use me to make points. I did graduate," I countered.
"And he's working. Sometimes two jobs. You've refused to get a job since you were fifteen," said Alice.
"I don't have to work," said Lila.
"So if you won't work and don't cane enough to graduate, what is your plan?" asked Alice.
"You just want to get rid of me so you can have our dad's money all to yourself! Goldigger!" snapped Lila.
Alice's face reddened. She hated being called 'goldigger'. To be fair, she had never actually spent much of our dad's money so the accusation was not true. But Lila often feel back on it because she knew it got a rise out of Alice.
"Enough!" I said stepping in. "You two have been doing this daily for a week now! Small wonder dad decided to go on his business trip! Now quit it! Or the neighbors will think there's some kind of domestic dispute going on here!"
"Fuck you Dennis! You always take her side!" screamed Lila.
"I'm sorry, what? Who was advocating for you three days ago to be given the money to go with your friends to Florida?" I asked. That shut her up. Because I indeed had defended her when she wanted to go to Florida in the summer with a group of her friends following graduation.
"If you don't graduate, you won't go," said Alice.
That made Lila throw her bag and stalk off, slamming her bedroom door. Now I rounded on Alice. "That did not help."
