Brother-in-law catches my husband fucking me from behind... then I show him what he's missing

Thanksgiving weekend, whole family crammed into our house. Everyone's stuffed from dinner and finally crashes out early—kids downstairs, parents in the guest rooms. Me and my husband slip into our bedroom around 11, door not fully shut because we're thinking everyone's out cold.

He's got me bent over the bed, pounding me hard from behind. My ass is up, tits swinging under me in this loose nightie, and I'm trying to keep quiet but moaning into the pillow every time he slams in deep. He's grabbing my hips, going faster, telling me how wet I am.

Then I hear the floor creak. Look up—my brother-in-law is in the doorway. He's my husband's younger brother, taller, more built from the gym, always got that cocky grin. Wearing just boxer briefs and a t-shirt, you can see the outline of him getting hard already. He's got that athletic tight body, unlike my husband's dad bod.

He sees us—me getting railed, ass bouncing, husband oblivious—and he doesn't move. Just stands there, leaning against the frame, eyes locked on me. I should've said something, but fuck, it turned me on more. I push back harder on my husband, moan a little louder, stare right at him while biting my lip.

Brother-in-law smirks, adjusts himself through the boxers—dick getting bigger, straining the fabric. He pulls the waistband down slow, lets it spring out. Thick, veiny, bigger than my husband's. Starts stroking slow while watching my tits bounce and my ass jiggle with every thrust.

I arch my back more, spread my legs a bit so he gets a better view of everything. Husband thinks it's for him, grabs my hair and goes harder. "You like that?" he grunts. I nod, but I'm looking at his brother jerking off in the doorway. Brother-in-law speeds up, thumb over the tip, eyes on my pussy getting fucked. He tenses, shoots ropes onto the hallway floor quiet as hell, then tucks back in and slips away with a wink.

Next morning, all the family bullshit—football on TV, leftovers, everyone hanging out. Brother-in-law keeps "accidentally" brushing against me in the kitchen, hand on my lower back, pressing that bulge against my ass when no one's looking. Wearing gray sweatpants that show everything.

Afternoon, husband passes out on the couch with a beer gut full. Family's out walking the dog or whatever. I'm in the laundry room folding shit when brother-in-law walks in, shuts the door behind him.

No words. He turns me around, pushes me down to my knees on the soft rug. Pulls those sweatpants down—dick already hard, bigger up close, throbbing.

"I've been thinking about your mouth all night," he says low.

I don't hesitate. Take him deep right away—thicker than my husband, stretches my lips. He's got better control, guides my head slow at first, then deeper. Tongue feels amazing swirling around him, hands in my hair not too rough. I go sloppy on purpose, like I do for my husband, but he pulls me off, makes me slow down, edge him.

"Fuck, you're better at this than I imagined," he groans.

I look up, take him all the way—no gag, swallow around him. He thrusts a little, fucks my mouth steady. I play with his balls, feel them tighten.

He warns me he's close. I just suck harder, hum around him. He grabs my head, pushes deep, unloads straight down my throat—hot, thick, more than my husband ever. I swallow every drop, milk him clean, lick the tip after.

He pulls up his pants, smacks my ass light. "Best Thanksgiving yet."

Walks out like nothing happened.
