The cabin smelled of pine, sweat, and the thick musk that always clung to the pack when summer heat pressed down. I watched from the shadows of the loft as my older brother Rake paced below, his broad wolf frame half in moonlight. His black fur gleamed, tail lashing, the heavy sheath between his thighs already swelling. We both knew what tonight was. Dad was gone on the long haul, and the rules we kept for the outside world fell away the second the door locked.
Rake looked up, yellow eyes locking on mine. “Get down here, pup. Been smelling you all damn day.”
I climbed down the ladder, paws hitting the floorboards. My own sheath was tight, cock already pushing out, the tapered tip slick. Rake grabbed me by the scruff the moment my feet touched ground and yanked me close. His muzzle crashed into mine, tongues wrestling, teeth clicking. The taste of him was salt and pine and brother. He shoved a paw between my legs, gripping my balls, rolling them rough.
“Fuck, you’re already dripping,” he growled against my mouth. His fingers slid back, found my hole, and pushed two thick digits in without warning. I whined, hips jerking, but pushed back onto them. Rake pumped them deep, stretching me open, the wet sound loud in the quiet cabin.
He spun me around and bent me over the old wooden table. My chest hit the surface, claws scraping. Rake kicked my legs apart and dropped to his knees behind me. His hot tongue dragged over my tailhole, lapping at the mess he’d made, then shoved inside. I howled, pushing back, grinding on his muzzle while he ate me like he was starving. His nose pressed under my tail, huffing my scent, and I felt his knot already starting to swell at the base of his cock.
When he stood, he didn’t tease. He lined up and drove in to the hilt in one brutal thrust. My hole stretched around his thick wolf cock, the ridges catching on the way in, until his swelling knot kissed my rim. Rake’s paws clamped my hips, claws pricking fur, and he started fucking like he meant to break the table. Every slam shoved me forward, wood creaking, his heavy balls slapping my own.

“Take it, little brother,” he snarled, voice ragged. “Been wanting this knot all week.” He pulled almost all the way out, then rammed back in, knot stretching me wider each time. Pre poured out of me onto the floor. My own cock throbbed untouched, slapping against my belly with every thrust.
Rake reached around, wrapped a paw around my shaft, and stroked in time with his fucking. His grip was tight, thumb smearing the slick over my tip. I came first, shooting hard across the table, hole clenching around him. That pushed Rake over. He forced his knot past my rim with a wet pop and locked inside, grinding deep as he pumped thick ropes of cum into my guts. The heat of it made me shudder and shoot again, smaller spurts this time.
We stayed locked, panting, his weight heavy on my back, tongue licking sweat from my neck. When his knot finally softened enough to slip free, cum poured down my thighs. Rake didn’t let me rest. He flipped me onto my back on the table, lifted my legs, and pushed back inside, slower this time but just as deep. His knot was still fat, rubbing every sensitive spot inside me.
“Gonna fill you till you can’t walk straight,” he promised, voice low and filthy. He fucked me through the second round, slower, grinding his knot against my prostate until I was whimpering and shooting dry. When he came again it was even more, overflow leaking out around his knot.
Later, we moved to the rug in front of the fireplace. Rake lay on his back, thick cock curving up against his belly, knot still half-swollen. I straddled him, sank down, and rode him while he watched my hole swallow him over and over. His paws roamed my chest, pinching my nipples through the fur, then gripping my ass to bounce me harder. We talked dirty the whole time—how wrong it was, how good it felt, how no one else could ever know the way we fit.
By the time the sun came up we were both spent, fur matted with cum and sweat, lying tangled together. Rake’s arm was heavy over my chest, his breathing slow. Outside the cabin the forest was quiet, but inside the den the scent of us lingered, thick and claiming. We’d clean up before Dad got back. Until then, the rules stayed broken, and we stayed locked together exactly the way we both needed.
