The sun blazed down on the clay court as 22-year-old Emma finished her final serve, her tennis skirt flipping up just enough to draw every eye on the court. She was the golden girl of the local club—long auburn hair in a high ponytail, toned legs from years of training, perky C-cup breasts straining against her white sports bra, and an ass that made her opponents (and her own brother) stare.
Her older brother, 24-year-old Ryan, stood across the net, sweat glistening on his muscular frame. He was built like a god—6’3”, broad shoulders, and packing something no one at the club could ever guess: a monster cock that stretched every pair of shorts he owned.
“Game, set, match,” Emma called out, smirking as she walked to the net. “Told you I’d kick your ass again, bro.”
Ryan grinned, pulling her into a sweaty hug that lingered a second too long. “Keep talking, little sis. Just wait till our camping trip this weekend. No refs, no rules.”
Emma felt a familiar forbidden thrill shoot through her. They’d always been close—too close. The kind of close where “innocent” wrestling matches turned into grinding, and late-night movie cuddles left her panties soaked. But they’d never crossed the line. Not yet.
The siblings loaded Ryan’s truck with camping gear and headed deep into the Georgia woods for a weekend “brother-sister bonding trip.” Their parents were away, and Emma had just won her regional tennis tournament. Ryan insisted they celebrate alone.
Halfway there, Emma changed into her tiniest denim shorts and a cropped tank top in the passenger seat. Ryan’s eyes kept drifting to her smooth thighs.
“Eyes on the road, perv,” she teased, but she parted her legs just a little wider.
At the secluded campsite by the lake, they set up the tent as the sun dipped low. After a quick dinner by the fire, Emma suggested a late-night swim. She stripped down to a white thong bikini that barely covered anything, her nipples hardening in the cool air. Ryan followed in black swim trunks that did nothing to hide the massive bulge already growing.
They splashed and laughed until Emma “accidentally” brushed against him underwater. She felt it—his monster cock, thick and heavy even soft, pressing against her ass.
“Ryan… what the hell is that?” she whispered, eyes wide.
He didn’t answer with words. Instead, he grabbed her hips and pulled her close, grinding his growing erection against her. “You’ve been teasing me for years, sis. Tennis skirts, tiny shorts, sitting on my lap during movies. I’m done pretending.”
Emma’s pussy throbbed. The forbidden word “incest” echoed in her mind, making her even wetter. “We can’t… you’re my brother.” But her body betrayed her—she wrapped her legs around him.
Back at the tent, Ryan didn’t waste time. He pushed Emma onto the sleeping bags, yanking her bikini top off. Her firm tits bounced free, pink nipples begging for attention. He sucked one into his mouth while his hand slid into her thong, finding her shaved, dripping pussy.
“Fuck, sis, you’re soaked for me.”
Emma moaned, arching her back. “Ryan… this is so wrong. Incest with my own brother…” The taboo words only made her hotter.
He stripped off his trunks, and his monster cock sprang free—10.5 inches of thick, veined perfection, the head already leaking precum. Emma’s eyes widened in shock and lust. “Holy shit… that’s never going to fit.”
Ryan smirked. “It will. But first, I want that pretty tennis mouth.”
He grabbed her ponytail like a handle and guided her head down. Emma opened wide, but his girth stretched her lips obscenely. He didn’t ease in—he facefucked her.
“That’s it, little sister. Take your brother’s monster cock down your throat.”
Emma gagged and drooled as he thrust deep, his heavy balls slapping her chin. Tears streamed down her cheeks, but she loved it—the incestuous roughness, the way he used her face like a toy. Saliva ran down her chin onto her tits as he fucked her mouth harder, grunting.
“Such a good little incest slut. Tennis champion by day, brother’s facefuck toy by night.”
She came just from the degradation, her pussy clenching around nothing. Ryan pulled out, strings of spit connecting her lips to his massive shaft, and slapped his wet cock across her face.
They didn’t stop. Ryan carried her out of the tent to a blanket by the fire. He ripped her thong off and spread her legs wide.
“Look at this pretty pussy. My sister’s cunt is dripping for her brother’s monster cock.”
He rubbed the fat head up and down her slit, teasing her clit, then pushed in. Emma screamed in pleasure-pain as her tight walls stretched around his enormous girth. Inch after inch disappeared inside her until he bottomed out against her cervix.
“Fuck! You’re splitting me open, Ryan!”
He started thrusting—long, powerful strokes that made her tits bounce. The sounds of skin slapping and her moans filled the dark woods.
“Say it, sis. Tell me you love incest cock.”
“I love my brother’s monster cock! Fuck your little sister harder!”
Ryan flipped her onto all fours and pounded her doggy-style, one hand gripping her ponytail, the other slapping her ass. He reached around to rub her clit, forcing another orgasm out of her.
The taboo of it all—sister camping alone with her brother, getting her brains fucked out—pushed them both over the edge. Ryan growled, “Gonna cum inside you, sis. Fill that womb.”
Emma pushed back against him. “Do it! Breed your sister!”
He roared and exploded, pumping rope after thick rope of hot cum deep into her. It overflowed, running down her thighs.
They collapsed, but the night was young.
Over the next two days, they barely left the campsite. Ryan fucked Emma in every position imaginable:
- Morning facefuck while she made coffee—her on her knees, throat bulging with brother cock.
- Tennis lesson turned fuck—he bent her over the picnic table in her skirt, no panties, pounding her while she still wore her tennis shoes.
- Lake blowjob—she sucked him off in the water, swallowing every drop.
- Rough breeding sessions—multiple creampies a day, him whispering filthy incest talk the whole time: “Gonna knock up my sister. Our baby will never know Daddy is also Uncle.”
Emma discovered she was addicted. She begged for his monster cock constantly, riding him reverse cowgirl by the fire, her tits bouncing as she screamed his name.
On the final night, he tied her wrists with rope from the tent and facefucked her mercilessly until she was a drooling, cum-covered mess, then fucked her ass for the first time—slow at first, then savage, claiming every hole his little sister had.
They drove home Sunday evening, Emma’s pussy and throat deliciously sore. She leaned over and rested her head on his shoulder.
“Best camping trip ever, big brother.”
Ryan smiled, his hand sliding up her thigh. “Next weekend we’re doing it again. And this time… bring your tennis outfit. I want to fuck you in it on the court at night.”
Emma shivered with anticipation. The incest door was wide open, and neither of them wanted to close it.
