You were the youngest, the one Sam and Dean had sworn to protect at all costs. Even though you were technically their step-brother—brought into the family when your parents died a hunt and John had to take care of you—the Winchesters treated you like blood.
Sam especially.
He was your big brother in every way that mattered: the one who patched you up after hunts, the one who made sure you ate properly, the one whose quiet presence made the bunker feel like home. You were so sweet, so naively sheltered. At eighteen, you still blushed at Dean’s dirty jokes, chewed on your hoodie strings when nervous, and looked at Sam with complete, unwavering trust. You had no idea how deeply that trust twisted something inside him.
Sam’s obsession had grown slowly, like a poison he couldn’t stop drinking. It started with protective glances lingering too long on your soft smiles, on your back, your waist, the shy way you’d curl up against him during movie nights. Then it turned darker. He began noticing your laundry—specifically the delicate lace panties you wore. One night, alone in his room, guilt already gnawing at him, Sam gave in. He pressed the soft lace to his face, inhaling your scent, and jerked off hard and fast, imagining your innocent eyes looking up at him. Afterward, shame crashed over him like ice water.
He’s your little brother. You’re supposed to protect him, not defile him. He swore it wouldn’t happen again. But the fantasies only grew stronger.
It was a quiet night in the bunker. Dean was gone for the weekend, chasing a lead in another state. You had fallen asleep early in your room, exhausted from a long research session, curled up in just an oversized t-shirt and those soft lace panties.
The door was ajar— you never locked it, trusting your brothers completely.
Sam stood in the hallway for what felt like hours, heart pounding. The guilt was suffocating. This is wrong. He’s innocent. He trusts you. But his cock was already hard, throbbing painfully at the thought of you sleeping so peacefully just a few feet away. He couldn’t resist anymore. Quietly, he slipped into your room, closing the door behind him with a soft click.
You were on your side, facing away from the door, breathing slow and even. Sam lay down carefully on the bed behind you, the mattress dipping under his weight. He stayed on top of the covers at first, just watching the rise and fall of your shoulder. Then his hand moved, trembling, to rest on your hip. You sighed softly in your sleep and leaned back into the touch, subconscious warmth seeking the familiar safety of your big brother.
Sam’s breath hitched. “Fuck…sweet boy.” He whispered, barely audible. His hand slid lower, cupping the curve of your ass through the lace. He squeezed gently, then bolder, fingers tracing the edge of the fabric where it met your skin.
You made a small, content sound and pressed back against him. His cock strained against his sweatpants. Sam freed himself, wrapping a large hand around his thick length and stroking slowly as he groped you.
He leaned in, nose buried in your hair, inhaling that clean, comforting scent. His strokes sped up, thumb brushing over the head of his cock as pre-cum slicked his palm. The guilt was still there, sharp and vicious, but it mixed with overwhelming lust. “You’re so perfect. I shouldn’t…God, I’m sorry, baby.”
You shifted again, unconsciously grinding back against his thigh. The lace dragged against his skin. Sam groaned lowly and slipped his hand under the waistband, fingers brushing over your clit and the warm, slick folds beneath. He didn’t push inside—just touched, reverent and hungry, feeling how your body responded even in sleep. You whimpered softly, hips twitching into his hand.
That small sound undid him. Sam jerked himself faster, breath ragged against the back of your neck.

Your eyes fluttered open slowly, mind hazy with sleep. At first you thought it was just another dream—Sam’s warm body pressed close, his hands on you. But then you felt the movement, the rhythmic motion, the heat of his bare cock against your lower back. You froze, shy confusion flooding your cheeks.
“S-Sammy?” You whispered, voice small and uncertain. You squirmed, which only pressed you more firmly against his stroking hand and cock. “What…what are you doing?”
Sam stilled for a second, but didn’t pull away. Instead, his voice came out low, soothing, and achingly patronizing. “Shh, sweet boy. It’s okay. Big brother just…needs a little help tonight. You feel so nice. So warm and soft. You don’t mind, do you?” His fingers continued their gentle exploration, stroking your clit with feather-light touches. “Look at you, leaning into me even now. Such a good, sweet little brother.”
You whimpered, a bit overwhelmed, but the praise made something warm bloom in your chest. Sam had always protected you. If he needed something…You would give it to him.
“It feels weird… but nice.” You mumbled shyly, hiding your face in the pillow. Your body betrayed your innocence, growing wetter under his fingers.
Sam cooed, nuzzling your hair. “That’s right, baby. It feels nice, doesn’t it? You’re making big brother feel so good just by being here.” He guided your hand back gently until your fingers brushed his thick cock, you gasped, sharp and breathless. “See how hard I am for you? That’s what you do to me.”
You touched it hesitantly, cheeks burning. “It’s really big, Sammy…”
He groaned at your innocent wonder. “Yeah, it is. And it needs your pretty mouth, little brother. Will you do that for me? Will you make big brother happy? You always like pleasing me, don’t you?”
The question hung in the air, gentle but heavy with something wrapped in affection. You hesitated only a moment—eager to be good, to keep that warm approval in his voice. “I— I want to make you happy, Sammy. I’ll try.”
Sam’s heart twisted with fresh guilt even as lust won. “Good boy. Such a sweet, perfect boy.” He helped you turn over and sit up, positioning himself against the headboard. You knelt between his spread thighs, shy and clumsy, staring at his cock with wide eyes.
“Go on.” Sam murmured, voice dripping with sweetness. “Open that pretty mouth. Just like sucking on your hoodie strings, but nicer. For me.”
You leaned in awkwardly, tongue darting out to lick the tip. The taste was salty, musky. You made a small surprised sound but continued, lips wrapping around the head. Your movements were inexperienced—too much teeth at first, then too tentative, bobbing shallowly while your hand fisted the base clumsily.
Sam’s hand settled gently on the back of your head, not forcing, just guiding. “Easy, baby. Relax your jaw. There we go… good boy. Look at you, trying so hard for big brother. So clumsy and cute. You’ve never done this before, have you? My innocent little brother sucking cock like it’s the most important thing in the world.”
You whimpered around him, the vibration making Sam’s hips twitch. Drool slipped down your chin as you tried to take more, gagging softly when he hit the back of your throat. Tears pricked your eyes from the effort, but you didn’t pull away. You wanted to please him.
“Shh, shh, you’re doing perfect.” Sam cooed, thumb stroking your cheek. His tone was so gentle, so condescendingly affectionate. “Such a sweet mouth. A little messy, but that’s okay. Big brothers are supposed to teach their little brothers, right? Just suck nice and slow…use your tongue. Yeah, just like that. Fuck, you’re a natural.”
He praised you constantly, voice low as you worked him. “Look how hard you’re trying. Eyes all watery and cheeks flushed. Adorable. You like making me feel good, don’t you?”
Your clit throbbed untouched in your lace panties, the praise making you squirm. You redoubled your efforts, hollowing your cheeks, taking him deeper despite the awkward angle and your inexperience. Sam’s hand tightened slightly in your hair, hips rocking gently to meet your mouth.
“That’s it, baby. You’re making me so happy. So close already…gonna cum for you. Be a good boy and swallow for big brother, okay?”
You nodded around him, eager and shy, eyes locked on his face for approval. Sam groaned deeply, thrusting shallowly as he came hard down your throat. You choked a little, swallowing what you could, the rest spilling from the corners of your mouth. Sam held you there through the aftershocks, murmuring endless praise.
“Good boy…such a good, sweet little brother. You did so well. Made me feel amazing.”
You just smiled.
