[F4F] brother x sister. Cabin fever
Cabin fever
Your wife’s last-minute work crisis killed the anniversary getaway you’d planned, but she insisted you not waste the booked cabin in the mountains. “Just go. Take your sister—she’s been talking about needing a break from the city anyway. You two always have fun together. It’ll be good for you.”
You called her right after. The excitement in her voice hit you instantly. “A whole weekend in a cabin with my big brother? Yes. I’m packing right now. Pick me up tomorrow after work—I’ll be ready.” Her happy laugh made the disappointment fade. By the time you hung up, the trip actually sounded good again.
But as you loaded the car—extra blankets, wine, the nice steaks you’d bought for “romantic dinners”—that old memory crept back in, uninvited and vivid.
It happened a few years ago during a family holiday at your parents' old lake house. Everyone else had gone into town for the day. The two of you were alone, bored, and messing around like always. A silly pillow fight on the big sectional couch turned into wrestling. You ended up on top, pinning her down on her stomach while she laughed and squirmed beneath you in a thin summer sundress.
Then the shift happened.
Your cock stiffened against the soft curve of her ass as she kept wiggling. The laughter faded. You remember the exact moment her body tensed... then slowly, deliberately relaxed. She didn't try to get away. Instead, she started pressing back— subtle little rolls of her hips, encouraging you. The thin fabric between you did nothing to hide how hard you were. You lost control, grinding against her harder, breathing against the back of her neck while she let out these soft, shaky little sounds. It was frantic, desperate dry-humping sounds.
It was
right there on the family couch. When you finally groaned and came in your shorts, shame crashed over you immediately.
You'd jumped up, muttered an awkward apology, and left the room fast. You spent the rest of the week terrified she'd say something-to you, to your parents, to anyone.
She never did. Not a single word in all the years since.
But sometimes you catch her watching you a little too long across the dinner table. Sometimes she "accidentally" brushes her body against yours when squeezing past in the hallway. Sometimes you swear you see her bite her lip and look away, like she's remembering exactly how it felt.
Now it's Friday evening. You pull up to her place and she steps out hair still damp from a shower. She wraps you in a tight hug, pressing close for a second longer than normal, her voice warm against your chest.
"This is exactly what I needed. Just us, no stress, no one else around... collagehas been killing me"
The twohour drive starts easy music, jokes, her bare legs stretched out, feet on the dash. She keeps shifting in the seat, the hem of those shorts riding higher each time. Every laugh, every casual touch on your arm when she reaches for
something, feels loaded now.
The cabin is secluded. One main room with a big fireplace, a loft bedroom, and total privacy. No neighbors. Just woods, a lake, and the heavy knowledge that you'll be sharing that space days.
As you unload the car, you can't stop the
thoughts
Does she still think about that day on the couch?
If the power goes out during a storm and you're both under the same blanket... would she press back again?
Would she want more this time?
She catches you looking and gives you a small, almost shy smile before turning to carry her bag inside, those little shorts clinging to her ass with every step.
This weekend is going to be full of long silences, lingering glances, and tension so thick you can barely breathe. The real question is how long you can both pretend nothing ever happened... and whether either of you actually wants to keep pretending once the sun goes down.
