This story happened during winter break of my senior year, but really, it started much earlier than that.
Everything began somewhere in my sophomore year. My mother had been seeing Sam for some time. He had two kids, a son and a daughter, and they decided we'd all move in together, to see if we could all get along under the same roof without killing each other.
So they moved into our house. It was larger, had enough rooms for everyone to get their own, and at first we got along pretty well, at least decently.
Michael, Sam's son, was older. He was 18 and would be graduating that year. Morgan was about a half a year older than me. We were in the same grade, but she went to this small liberal arts school. She was an "artist." She kept to herself, ran with this uptight, condescending crowd that rolled their eyes at me whenever I tried to introduce myself.
I didn't mind Morgan. She was nice, sometimes at least a little interesting. And she was cute, small and skinny, a little curvy, with a little belly, but big tits and a nice ass. She had dark brown, curly hair. If she'd have expressed any interest I would have jumped on her in a heartbeat, but she was cold and distant, too aloof. Anytime I even tried to flirt with her, she'd just smile and laugh and cut the conversation short.
Michael, on the other hand, was a fucking prick. He was taller than me, lanky, but smart. He was always apt to talking down to me, mocking me whenever he could. We'd get in little spats about what to watch on TV, that sort of thing, but mostly I just considered him a blowhard, full of hot air, and he never brought home any cute girls or went out on dates, so I'd let it slide, knowing I was fucking girls in his grade that he'd probably give his left nut just to kiss.
But everything changed one night at dinner.
I had just gotten home from hanging out with some friends, and I'll admit, I was stoned off my ass. We'd gotten some good bud and rolled a joint, hung out a little before I skateboarded home.
I'd used some eye drops and mints, the scent masked by body odor and some cheap body spray, I figured nobody would know.
We were all sitting around eating, and I was just destroying whatever it was my mom made, when I realized everyone else was silently staring at me.
I looked up, looking around at them.
"Well?" My mom asked, staring at me.
"Huh?" I asked.
"I asked how how school was." She snapped, impatiently.
"Oh, fine, not too bad." I said, stuffing my face. "Soccer practice was alright, skateboarded afterwards."
"That must be why you're so hungry." Sam laughed, shaking his head.
"Yeah, sure." I said, turning back to my meal.
"And tired, you look pretty worn out." My mom interjected.
"Yep, pretty much." I said, trying my best to finish my meal so I could leave.
"Ah come on, are you guys serious?" Michael chimed in, laughing.
I stared up at him, daggers in my eyes, not willing to believe he was actually about to call me out in front of everything.
"What are you talking about, Michael?" Sam asked, and Michael gestured at me, shaking his head and rolling his eyes.
"He's stoned off his ass! Probably gets high every day at the skatepark, how are you two so fucking oblivious?"
I'll spare you all the details, but the next few months were a very difficult time for me: I was grounded, I had to deal with more arguments with my mom, threats, chores, they even signed me up to see a therapist, which was just utter and complete bullshit.
Eventually, things blew over, and my life got back to normal. But I had to be pretty sneaky, at least until Michael went off to college. Full ride scholarship, Ivy league; fucking prick.
I never forgot what he did though, the shit I had to go through for little more reason than a sadistic whim on his part, and I swore, if I ever got the chance, I'd make him pay.

Fast forward to my Senior year, winter break. Our parents had been married for a year now, and everything was going as decently as possible. But Michael was back in town from college, always prattling on about his high grades, his adoring professors, which grad schools he was considering, what fortune 500 company he'd be running in ten years.
I was going crazy being under the same roof with him. He'd become even more insufferable, so I spent the majority of the time at my friend, Ryan McCain's house. Ryan's mom seemed to always be gone, at her boyfriend's or at work, never home, and she didn't even care what we did, as long as she got a little bit of weed from us every now and then.
One day we decided to go to the skatepark, so I headed home to grab my skateboard. It was cold, but it hadn't snowed in a while. My mom and Sam were both still at work, it was early in the day, but Morgan's car was in the driveway, and so was Michael's.
I slipped inside, trying to get in and out without having to talk to him, when I heard a strange noise. It was a dull thud, over and over again, something unfamiliar.
I crept up the stairs, and down the hallway I could hear noises. Morgan's voice, distinctly, grunting and groaning. Her door was barely cracked, and leaning in, I could see her, naked, straddling Michael, her big tits, floppier than I'd expected, swinging to and fro.
I smiled. I didn't just smile, my head raced with euphoria and vengeance. I slipped off into my room. This was in the days before Iphones and cameras on every cell phone, but I had a videocamera. I used it for skateboarding movies usually.
I grabbed it and checked the battery, thanking my lucky stars that it was almost full. I grabbed my skateboard and rewinded the tape to the beginning: this was so much better than whatever tricks I had recorded.
I crept back into the hallway and up to her door. Morgan was on her hands and knees now, and I had a perfect shot of both of their faces, going at it. He fucked her hard and fast, grunting and riding her from behind.
I stayed still, getting a good shot of everything. Him riding her, her riding him, her sucking him off, I waited patiently until he was finally fucking her from behind again, then I pushed open the door.
They both looked up like deer caught in headlights, freezing and staring.
"That's your fucking sister, Michael!" I screamed, laughing wildly. "You're fucking you're sister."
"What the fuck!" He screamed, turning red. "Colin, give me the camera."
He stood up and I got a good shot of his naked body and his cock. He was average, if not a little below average, and I was glad knowing my dick was much bigger than his.
"GIVE IT TO ME!" He screamed, lunging forward and tripping over the blankets. I laughed, pointing the ccamera down at him.
"You're a sick fuck, Michael, you're a sister fucker! You fuck your own sister!" I laughed, racing down the stairs and skateboarding off.
I could hear him chasing after me, but as soon as I was out the door, I knew I was good. Michael would have to double back to get clothed, and by then I was gone.
I made it to Ryan's house, shook up and quiet. I decided not to go to the skatepark after all. I had too much thinking to do.
***************************************************
Dinner that night was strained, to say the least. Morgan was gone, at a friends house or something, but Michael showed up. He was silent, staring at me, then off into space. It was amazing, I could barely enjoy the meal, I was too busy eating up his agony and discomfort.
"Michael, everything ok?" Sam asked, smiling at his son.
"Huh? What?" Michael piped up. "Oh, yeah, just tired."
"I would be too, if I were you." I said, laughing.
"What?" My mom asked, oblivious.
"Michael had a pretty rough workout today." I said, laughing. His face shot up at me, pleading, eyes wide.
"What? I saw you jogging earlier." I said, smiling.
Sam laughed, shaking his head.
"Michael, I didn't know you'd taken up running. We should go on a run sometime!" He exclaimed, beaming at his son.
"Oh, yeah, sure pop." He barely whispered.
"You didn't know?" I asked, laughing. "Michael, why would you keep that a secret? What other secrets do you have?"
Michael sat there, staring at me, his face blank.
"Well, I-" He started, before I interrupted him.
"You know it's funny, everyone has these little secrets, and you don't even think about it. But then you find out, and it changes everything." I smiled.
"Well, yeah, I guess you're right, Colin," Sam laughed. "This really does change everything, because now I'll be waking Michael up every morning for a run. Ha! That must be why you kept it a secret, huh? So you wouldn't have to get up at the crack of dawn to go jogging with your old man."
"Ha, yep, pretty much." Michael laughed uncomfortably, and I couldn't be happier.

That night, I was relaxing on my bed, reading up on some winter break homework reading, when I got a knock on my door.
