All Chapters of Sinful desires: MM Steamy compilation : Chapter 31 - Chapter 40

When my mom remarried and I got a new stepbrother, I thought I would hate him but instead he became my best friend and everything I ever wanted. But things started going the wrong way when I walked in on him, watching gay porn and jerking off. My brother was gay? And worse, my cock jerked at the sight of him. ******“Gavin, this is your new mom and her son, he’s gonna be your new brother”. Twelve years old me stared at the two strangers my dad had introduced with a smile on his face. I could tell the boy didn’t want this as much as I didn’t but he was just silent, staring at his feets. “But I don’t want a new mom”, I said, tears about to spill from my eyes. They are gonna take my father away from me. Since my mother passed away, my father and I have always done everything together. “I don’t want to share my dad with another brother. I don’t want him”. I cried. “Why can’t he just stay with his mom?” “Gavin, don’t say that. They are nice people, she’s gonna be your mom too. Your fri

I felt out of place the second we walked in.Music blasted through the house, loud enough to make the walls tremble. Bodies moved everywhere—laughing, grinding, shouting over each other. Someone knocked into me with a red cup in their hand and didn’t even apologize.Summer vacation had finally arrived. Last day of school. Apparently that meant getting drunk until you forgot your own name.Leon had practically dragged me here.“Don’t be such a nerd,” he’d said, grinning. “You’re nineteen, not ninety.”So now here I was. Nineteen. Miserable. Standing against a wall while everyone else celebrated like they’d just been released from prison.The air smelled like alcohol and sweat. People were dancing on tables. A couple disappeared down the hallway, laughing too loudly. Someone was already throwing up in the bathroom.I shoved my hands into my pockets.And Leon?Nowhere.I scanned the crowd again, irritation building in my chest. He’d forced me to come, called me boring for wanting to stay

Gavin POVI lay sprawled across the mattress, sheets tangled around my hips, the faint stickiness still clinging to my skin even after I’d scrubbed myself raw in the bathroom. The room smelled faintly of soap and shame. My heart hadn’t stopped hammering since I’d come—hard, embarrassingly fast—with Leon’s face flashing behind my closed eyelids like some forbidden movie reel I couldn’t pause. His sharp jaw, the way his dark hair fell across his forehead when he laughed, the low timbre of his voice when he teased me in front of our parents. All of it. Every detail had burned itself into me tonight, and now I couldn’t unsee it.I stared at the ceiling, the familiar cracks forming a crooked map I’d memorized over years of lying awake. What the hell was wrong with me? This wasn’t supposed to happen. He was my stepbrother. Younger by eighteen months, sure, but still family. I almost didn’t hear the soft click of the doorknob turning.“Gav…”Leon’s voice was barely above a whisper, careful,

Gavin POVThere’s something hard pressing against my ass.I frown in the hazy half-light of early morning, shifting slightly as consciousness creeps back in. My eyes flutter open, and it takes a second for the fog to clear. I’m sprawled on top of Leon—completely, shamelessly draped over him like a human blanket. My chest is flush against his, my legs tangled with his longer ones, and my face is tucked into the crook of his neck. His heartbeat thumps steadily beneath my ear, strong and familiar.A deep, mortifying heat floods my face, then races downward until my toes curl.This isn’t new. We’ve ended up like this dozens of times over the years—crashing together after late-night movies, passing out during video game marathons, or just because one of us rolled too far in our sleep and the other didn’t have the heart to shove them away. Usually, when one of us woke up first and felt the unmistakable press of morning wood, we’d laugh about it. Tease each other mercilessly. “Dude, seriousl

Gavin POVI lay under the blanket, the room thick with darkness except for the faint blue glow from my phone screen. It was past 11 p.m.—way past—and I’d waited, until Leon’s breathing finally evened out across the gap between our beds. It had taken forever. He’d tossed and turned for what felt like hours, the mattress creaking every time he shifted, like his body was fighting sleep as hard as mine was fighting the ache between my legs. We were back in our separate beds now after the kitchen almost-happened. After Mom and Dad walked in laughing about their weekend getaway, oblivious to the way my lips still tingled from Leon’s fingers, the way his hand had fisted in my hair like he was seconds from dragging me to my knees.I couldn’t stop replaying it. The heat of his grip on my neck. The way his cock had strained against his sweats, so close I could almost taste the salt and musk through the fabric. He’d pushed my head down and I’d gone willingly, mouth already watering. If our paren
