He Fills Me Full at the Lake House

Family vacations had always been a special kind of hell for me. Not the kind of hell other kids complained about—long car rides, boring destinations, forced smiles for photos. No, mine was the kind where your parents treated every mile like a performance review, every stop like an opportunity to remind you how disappointed they were in everything you did or didn’t do. Mom and Dad were the ultimate uptight pair, the type who polished their image harder than they ever polished anything real in their marriage. They inherited the lake house from Grandpa after he dropped dead mid-thrust with some working girl he’d been seeing on the side. The place itself was decent enough: big enough for separate bedrooms, a solid TV that actually got channels, and a lake that stayed cold even in the middle of summer. But the drive? Seven hours of Dad’s terrible classic rock or Mom’s endless audiobooks about self-improvement that never seemed to improve her. Headphones were the only thing that kept me sane.

This year was different. School had barely let out when Dad announced we were packing up early. The divorce was already in the air, thick as the tension that had been building for months. Mom had caught him cheating—again—and the nightly arguments had become the only entertainment Alice and I could count on. We’d sit at the top of the stairs throwing popcorn at each other while they tore each other apart downstairs. Alice was nineteen, a year older than me, and she’d been held back so we were finishing senior year together. She wasn’t the sharpest, but she was the only person who made the whole mess bearable. We’d grown up glued to each other, parenting ourselves while Mom and Dad played their little social climbing games. The only problem was that somewhere along the way, my feelings for her had stopped being brotherly. Every wet dream, every hard-on in the shower, every time I jerked off thinking about those pink pouty lips wrapped around my cock—it was always Alice. Long brown hair, big brown eyes, perky C-cup tits that bounced when she walked, and an ass that filled out every pair of shorts she owned. I’d fucked other girls, sure. Ava from school had looked enough like her that I could close my eyes and pretend. But nothing ever scratched the itch. Not until the night before we left for the lake house.

I was stretched out on my bed, some book I wasn’t reading open on my lap, when the door cracked open and Alice slipped inside. She was wearing this tiny silk nightgown in baby pink, so sheer I could see the dark shadows of her nipples and the outline of matching panties. The hem barely covered the curve of her ass. My cock went from soft to iron in seconds. I shifted the book to hide it, but she saw the way I looked at her. She always did.

“You okay, Ben?” she asked, voice soft.

“Yeah. You?”

She sat on the edge of the bed. The nightgown rode up her thighs. Her hand found my knee. “Not looking forward to tomorrow.”

“Tell me about it.”

She turned more toward me, knee up on the mattress, ankle tucked behind her calf. More thigh. More pink fabric. “At least they’ll be too mad to fight. Hopefully just the radio the whole way.”

I nodded, throat dry. “Then we can avoid them once we get there.”

She bit her lip. A blush crept up her cheeks. “I… um…”

“What’s wrong?”

Her eyes dropped to my lap. The book had slid. My cock was tenting the thin pajama pants, obvious as hell. She giggled. “Were you reading something naughty?”

I shook my head. Couldn’t speak.

“Or is it for me?” Her voice dropped, low and knowing. Her hand slid higher up my thigh. “I know you think about me. I can hear you when you jerk off. Wishing it was my mouth. Or that you were inside my pussy.”

Holy fuck. The words hit me harder than any fantasy. She gripped the waistband of my pants and pulled them down. My cock sprang free, thick and already leaking. She smiled, fingers tracing from base to tip, pinching the head just enough to make me hiss.

Then she slid off the bed and knelt between my legs. Her hands wrapped around the base, pumping slow. “Would you like me to suck your cock?”

I nodded. Still no words.

She leaned in and licked the tip, tasting the precum. Then those pouty lips parted and she took me in, just the head at first, sucking gently while her tongue swirled. I groaned. She sank lower, inch by inch, until the head bumped the back of her throat. About two inches stayed outside; she used one hand to stroke what she couldn’t fit. She hummed around me, the vibration shooting straight to my balls.

“Fuck, Alice.” My hands found her hair. She bobbed, perfect pressure, one hand working the base, the other cupping my balls and rolling them. I watched my sister’s mouth stretch around my cock and almost came right then.

“You love my cock in your mouth, don’t you?”

She looked up, eyes wide with lust, and hummed again. Deep-throated me harder.

“Best cock you’ve ever swallowed.”

Another hum.

“I’m going to cum down your throat and you’re going to swallow every drop.”

She squealed around me, eyes flashing excitement, and sped up. I thrust up to meet her, fucking her face while she took it like she was born for it. The pressure built fast. “Fuck, I’m gonna cum.”

I gripped her hair tighter and buried myself as deep as I could. My cock pulsed and I shot load after load straight down her throat. She swallowed every drop, eyes locked on mine the whole time. When she finally pulled off with a wet pop, my cock was still twitching. I hauled her up into my lap, straddling me, and kissed her hard. I could taste my own cum on her tongue and it only made me harder again.

I flipped her onto the bed, ready to rip those panties off and bury myself inside her, but she stopped me with another kiss.

“Not yet,” she whispered against my mouth.

“Why?” It came out like a whine.

She giggled. “Because tomorrow’s going to be a long drive. And I want you aching for it the whole way. But…” Her hand wrapped around my cock again, already half-hard. “I can take care of this for now.”

She stroked me while we kissed, slow and dirty, until I was fully hard again. Then she slid down and sucked me a second time, slower, deeper, teasing. She let me fuck her throat until I came again, this time pulling out so the last spurts painted her tongue and lips. She swallowed, licked me clean, and kissed me once more before slipping out of my room like nothing had happened.

I barely slept.

The next morning we packed the car under the usual cloud of passive-aggressive silence. Mom in the front passenger seat with her audiobook already queued. Dad behind the wheel, pretending everything was fine. Alice and I in the back. She wore a short summer dress, the kind that rode up when she sat, and I could see the edge of fresh pink panties. Every time she shifted, the fabric flashed. My cock stayed half-hard the entire first hour.

Halfway through the drive she leaned close, voice low so our parents couldn’t hear over the radio. “Still thinking about last night?”

“Every second.”

Her hand found my thigh under the cover of a jacket I’d draped across both our laps. She stroked higher until her fingers brushed the bulge in my jeans. “Good. Because I woke up soaked. Had to touch myself thinking about your cum in my mouth.”

I bit back a groan. She unzipped me carefully, freed my cock, and wrapped her fingers around it. Slow strokes while Mom and Dad argued quietly about some trivial bullshit up front. Alice’s thumb rubbed over the head, spreading precum. She leaned in like she was just resting her head on my shoulder and whispered, “I want you to finger me. Right here. Make me cum before the next stop.”

I slid my hand under her dress. Her panties were already damp. I pushed them aside and found her pussy slick and hot. Two fingers slid into her easily. She was tight, walls clenching around me as I curled them against the spot that made her breath hitch. I rubbed her clit with my thumb while I fucked her with my fingers, slow and steady so the car wouldn’t rock. She kept stroking my cock in the same rhythm. We both came quietly—her biting her lip hard enough to leave marks, me spilling over her fist. She licked her fingers clean afterward and wiped the rest on a napkin like it was nothing.

By the time Dad pulled into the truck stop for gas and food, I was hard again. He told us to head inside for lunch while he filled the tank. Mom went straight for the diner. Alice adjusted her dress, glanced at the wet spot on my jeans, and shrugged. “Your own fault.”

I pulled her close outside the diner doors. “I’ve got a hard cock that needs attention. Your little brother would love to shove it down your throat again, but if you’re worn out I’ll understand. I’ll be in the bathroom.”

I walked away without looking back, hoping like hell she’d follow.

The public restroom was exactly as disgusting as expected—sticky floors, flickering fluorescent lights, the smell of industrial cleaner fighting a losing battle with piss. I checked the stalls. Empty. Leaned against the sink and waited. The door swung open less than a minute later. Alice stepped in, locked it behind her, and leaned against it with a wicked little smile.

“Little brother, I think you’ve earned something special.”

I crossed to her. “Really?”

She nodded. “I want you to bend me over these sinks and fuck my wet cunt. I want to be full of your cum while we sit across from our parents.”

I groaned, spun her around, and pushed her toward the mirrors. No more teasing. I yanked my jeans and boxers down just enough for my cock to spring free. She hiked her dress up over her hips. Her panties were soaked through, thighs shiny with her own juice. I tore the fabric apart with both hands and dropped the ruined scrap on the floor. Spread her ass cheeks and rubbed the head of my cock up and down her slit.

“Fuck me, little brother.”

I pushed in hard. Her cunt stretched around me, hot and dripping, walls gripping every inch. I bottomed out and held there for a second, feeling her pulse around me.

“Ben—I’m so full—”

I pulled almost all the way out and slammed back in. Set a brutal pace right away, hips slapping against her ass, the wet sounds of her pussy loud in the empty bathroom. She braced on the sinks, watching us in the mirror—my cock disappearing into her, her tits bouncing under the dress, her face flushed and open-mouthed.

“So fucking tight,” I gritted out. “This cunt was made for me.”

I grabbed her thighs, lifted her feet off the ground, and used the extra angle to drive even deeper. Her ass cheeks flattened against my stomach with every thrust. She came hard, walls clamping down, a broken cry echoing off the tile. I didn’t stop. Kept pounding through it until she was whimpering, oversensitive, legs shaking in my grip.

I set her feet down but stayed buried. Kissed her shoulder. “How do you feel?”

She pushed back against me in answer.

“Want more?”

“So sensitive—”

I pulled out, rubbed the head through her folds, and asked, “Mouth or cunt? Where do you want my cum?”

She turned, still holding the sink. Looked down at my cock shiny with her juice. “Inside me. I need it in my cunt.”

I lifted her again, wrapped her legs around my waist, and thrust back in. The sink creaked under us. I fucked her harder this time, kissing her to swallow the louder moans. Her second orgasm hit fast and messy; she soaked my cock and balls. The tight fluttering pulled me over the edge. I buried myself to the hilt and came in long, heavy pulses, flooding her. Felt it leaking out around my cock already.

When I finally pulled free, a thick rope of cum dripped from her open pussy onto the floor. She dropped to her knees without being asked and cleaned my cock with her mouth, slow and thorough, until I was half-hard again in her throat. I helped her up.

“No cleaning yourself up,” I told her. “I want that cum staying inside you until we get to the house. I’ll clean you out later myself.”

She nodded, still catching her breath. “I’ll need clean panties or it’ll soak through onto you in the car.”

My phone buzzed—Dad wondering where we were. I grabbed the torn panties from the floor and stuffed them into the front of her dress between her tits. “Wouldn’t want any random guy finding these.”

We cleaned up as best we could, straightened clothes, and walked out like nothing had happened. Lunch was quiet. Alice sat across from me with my cum slowly leaking into her new panties. Every time she shifted I saw the tiny smirk.

The rest of the drive was pure torture in the best way. She kept her hand under the jacket, teasing my cock through my jeans, whispering how full she still felt, how she could feel my load shifting inside her every time the car hit a bump. By the time we pulled up to the lake house I was ready to drag her straight to the nearest bedroom.
