[F4A] Silent Night, Sinful Touches brother x sister incest story please read below

It’s the first night of Christmas break, and the house is exactly how I remembered it cozy, warm, and way too small for how loud my heart is hammering right now. The whole family is piled into the living room for our annual movie night tradition. Lights are dimmed, the Christmas tree twinkles softly in the corner, and the latest holiday blockbuster is playing on the big screen. Mom and Dad are settled in their usual spots on the recliners, snacks in hand, completely absorbed in the movie and half asleep already after the big welcome home dinner.

I’m stretched out on the big sectional couch under a thick, oversized blanket, trying to focus on the screen. But I can’t. Not when you’re right here beside me my younger sister, who apparently decided to grow up spectacularly while I was away at college.

Fuck… you’re not the same girl I left behind. The shy, awkward tension that used to flicker between us has turned into something dangerous. Your body has filled out in all the right ways soft curves, full breasts straining against that thin tank top, hips and thighs that make it impossible not to stare. Every time you shift under the blanket, I catch the scent of your shampoo and something warmer, sweeter. The unspoken heat that used to make us glance away too quickly is now crackling like electricity.

You’re cuddled up close closer than necessary our legs lightly tangled under the heavy blanket that hides everything from our parents just a few feet away. The movie drones on, but all I can feel is the heat radiating from your body. My hand rests innocently on my own thigh… until it doesn’t. Slowly, carefully, my fingers brush against yours beneath the blanket. Testing. Waiting to see if you pull away.

The risk makes my pulse thunder. Mom laughs at something on screen. Dad shifts in his chair. One wrong move, one muffled sound too loud, and everything could explode. But I can’t stop. Not when you’re this close. Not when I’ve been thinking about you more than I should have these past months.

My fingertips trace lightly up your thigh, slipping just under the hem of your soft shorts, heart pounding as I feel the smooth, warm skin I’m not supposed to crave. I lean in just enough to whisper, voice low and rough against your ear, barely audible over the movie:

“…You’ve changed. A lot.”

My hand dares to move higher, slow and deliberate, testing how far you’ll let this go right here under the covers, inches from our oblivious parents. The forbidden thrill is already making me hard, pressing against my sweatpants, dangerously close to brushing your leg.

Your move, sis. Do you freeze? Tease me back? Or finally give in to the tension we’ve both been ignoring for years?
