Seth lay back against the pillows, closing his eyes. It had been a long, hectic first day at Fablehaven. The house felt rustic and run down, but at the same time huge and with so many interesting nooks and crannies to explore. He was excited to do so, although the rooms felt a little dank and drafty.

He wondered why they couldn't enter the barn or the woods. Maybe there were giant animals there that Stan and Ruth were hiding? He imagined a giant cow and laughed at that. As for the woods, maybe there were magical creatures in there, like giant ticks that jumped on you from behind and gave you super-Lyme disease.

As he fantasised, he tossed and turned trying to sleep. The chicken was already fast asleep, but Kendra, his sister, clearly wasn't. He glanced at her unobtrusively. Her eyes were open, staring at the ceiling.

How does he describe Kendra? She was just slightly taller than him, with perfect eyebrows and long eyelashes covering her huge innocent chocolate brown eyes. She had full lips and wavy, flowing caramel brown hair down past her shoulders. She was in good shape - not muscled, not fat, just in between. Her breasts were well developed for her age.

He continued looking at her, making sure she wouldn't notice. And as he looked, her hand went down between her legs, covered by the sheet.

Her body began to move, her hips gyrating and moving up and down, pushing up the sheet and slamming her ass against the bed. He could see the outline of her forearm underneath the sheet, leading to the junction between her thighs. As her whole body moved rhythmically, hypnotically, sweat beaded on her forehead and small moans emerged from her lips.

"Seth..." she moaned.

Seth gasped in shock, then tried to hold his excitement. Instantly, his cock hardened, standing straight up against his pants. So Kendra had feelings for him too! Ever since she was young, about the time that her breasts developed, Seth had vivid fantasies and dreams of them being together. He couldn't believe that Kendra shared his feelings.

Seth fought the urge to grasp his cock and stayed still. After a while, Kendra's movements subsided and she went still, closing her eyes. After waiting a minute or so to make sure she was asleep, Seth grasped the tip of his cock with his thumb and index finger.

He started to jerk off. After a few minutes of soft, slow movements, taking care not to move too much while fantasising wildly, he realised that he could have the real thing.

He glanced over at his sleeping sister, made up his mind, got up and crossed over to the light switch. Flicking it on and locking the door, he walked over to Kendra's bed. He shook her shoulders. "Sis, wake up."

Her eyes snapped open. "S-s-seth?" she stuttered.

"I saw you fap."

Her face reddened, her cheeks turning the color of a ripe apple. "I-i-its not what it looks like!" she said hotly.

"Oh, really? Well, don't be ashamed. I have been feeling the same things about you for 4 or 5 years now. Every day, I imagined you doing crazy things to me, on me. I fapped to your pictures every single day back then. And now it seems the feeling is mutual..."

"Well.. I do fap while thinking of you sometimes - but this is wrong! I'm your sister, you can't-" her voice trailed off as she saw his cock standing straight up. In admiration, Kendra said, "that's... a big... um..."

"That makes it kind of kinky, don't it, Kends?" Seth murmured. A second later, his lips crashed against his elder sister's.

She resisted for a few seconds, then gave in to the temptations. She pressed her lips against Seth's, reveling in the smooth texture of his lip flesh and how it rubbed against her big full lips. As she rubbed her mouth against his, he grabbed her chin to open her mouth and stuck his tongue in, licking at every bit of exposed flesh, from the roof of her mouth to the inside of her cheek. Her tongue reciprocated and licked, pushed against his. The two red outlines were firmly locked together, moving in symphony, like Neo's kiss of Persephone, but with something extra. Love.

He broke away; then leaned in. With his fingers and tongue he explored every nook and cranny of her beautiful face. He ran them through her long caramel locks. Gently he kissed down his sister's jawline, to her neck and exposed chest, nipping every bit of skin.

He stopped.

"C'mon, baby brother!" Kendra teased. "What are you scared of? You want my melons? Take them?"

Seth's eyes hardened. "Get down on your knees."

"Yes, baby brother," she whispered seductively, getting off her bed and kneeling. She stripped of his pants and underwear, letting the entirety of his hard, thick cock spring free.

Kends blew on the tip, then leaned forward and pressed her full lips around the glans. Seth closed his eyes and groaned. "You have no idea how many times I dreamed of that..."

"This will be better," Kends promised, then dropped her shoulders.

Those lips and teeth travelled down the shaft and came to rest kissing his crotch.

The whole length was buried in the warm wet envelope of his big sis' mouth. And she moved.

It felt so wrong, so depraved, and yet he loved the taboo of it, which turned him on. With his own eyes he witnessed his beloved big sis, whom he had known for years, sucking his cock. The mouth than had mocked him, made fun of him, teased him, was giving him a blowjob.

Her full lips formed a seal that moved up and down his shaft, like a warm tight finger hole of a glove moving up and down. It was so damn wet, as she salivated heavily and used her tongue, stimulating him further.

Kendra gurgled. "This.. so... wrong..."

"And it feels so right.." Seth grabbed her beautiful caramel hair, his fingers bunching up the long wavy curls behind her head. He used it as a handle, dictating the pace and pumping his sister's mouth in and out, in and out. He felt his cum rising. No, he couldn't stop.

He yanked back hard and pulled her head off. A strand of saliva remained connecting her lips to his cock. "Not so fast..." he growled.

She panted, immensely enjoying it, the fetish of being his slave. "Anything... master..."

He dumped her on the bed and took off her shirt, bunching it up before tossing it to the chicken's cage. He unbuckled the bra and peeled it off. Her melons sprung free. Beautifully shaped, two ivory domes of soft spongy flesh tipped with sweet cherry red nipples. "Oh god.. oh god.. you have no idea... how long I waited... to see those..."

"They're yours, Seth," Kends moaned. "All for you..."

He groped his sis, fondled her breasts, his fingers sinking hard into the underboob, the soft flesh giving way beneath his grasp. And they moved, massaging the titflesh, in and out, in and out. As he pressed and pulled he was mesmerised by how her breasts changed shape, first flattening longitudinally and expanding laterally, then the other way round. He changed focus, running his palms from the neck down the curves of his big sister's boobs, then pressing both palms against her nipples and swirling his palms, feeling the nipples rub against his skin. She moaned his name, a sheen of sweat covering her face.

Then he leaned forward and pressed his lips to one nipple, sucking in as much of the soft flesh into his mouth as he could, toying with the sweet red tip with his tongue. He tweaked the other nipple with a middle finger, then switched order. Her moans grew louder and louder in intensity, music to his ears.

Then he sat on her stomach, straddling Kendra and shifting forward. He moved his sister's breasts apart and inserted his cock into the dough rolls, pressing them inward to form a slippery tunnel and moving in and out, in and out. She craned her neck to lick the tip as he did so. She watched as he committed this act of insane depravity on his big sister and she loved every second of it.

The cum rose again, he rolled off and waited a few seconds for the throbbing to subside and then returned. He laid a fiery trail of kisses down his sis' belly, especially on her navel, then reached her pussy. In one smooth movement, he stripped off her skirt and panties, stuffing them under the bed.

He buried his forehead in her mons, the soft layer of flesh above the cleft, then began exploring the golden dewy folds with lips and tongue.

She moaned and screamed his name as he licked the outside of her folds to lubricate it, then went deeper, sticking in his tongue and exploring the walls of her moist vagina, licking and nipping every single bit of the red flesh. She had already fapped so it was easier to get her over the finish line. He went as deep as he could, tasting some of the wet liquid coating her vulva, then suddenly moved slightly up and focused on her clitoris. He stuck two middle fingers into his sister, then stuck his tongue into the cleft again.

Kendra let out a loud scream, the loudest so far. "My baby brother. Oh god... please me... please please me..."

He put his tongue against the underside of the clit, rubbing and pulling until it was pronounced and then putting his teeth on to grasp it, sucking at every single bit of the soft sensitive skin packed with more nerve endings than the whiskers of a catfish (Ok, that was hyperbole). As he devoted every bit of energy to the little organ, he felt wetness welling up. "I'm gonna spurt!"

He wondered whether to drink, then decided not and was walking out of the door as she sprayed like a fountain. Kendra moaned as the femcum poured out of her wet cunt onto the bed sheet. "Where are you g-g-going, brother?" she asked, chattering as the pleasure racked her body, and the spasms travelled up and down her spine.

"You'll see."

He rushed down to the fridge, grabbed a stick of butter, and brought it back up. He tasted a bit of it. Rich, sweet and creamy. Perfect. He grabbed a nice soft breadstick too.

He slammed open the door and saw Kendra pumping her own fingers in and out. "Seth, I need you. Come on, baby brother. Put your-" her voice trailed off. "Is it butter?"

He flipped her on her belly and maybe she realised what he wanted. "No. Noooooo..."

"I want to have some fun with your ass," he explained.

"Can't you-"

"Nah, I don't like it. It'll get too dirty for my taste."

"You scared of a little dirt?" Kendra teased.

"What did you say?"

"I said, you scared-"

He slapped her as hard as he could. The sound of his palm against her ass rang out against the room. All four cheeks jiggled and she broke out into another moan.

Then he slapped her again, and again, and again...

"Who's your master?" Seth bellowed. "Who's your owner, big sis? Tell me!"

"You are!" she gasped. "I'm your slave!"

"I'm your slave and you can do anything you want with my body!" she screamed.

"Good," Seth said menacingly, then went to his emergency kit. With his knife, he cut off a chunk of butter which he inserted into Kendra's ass, using his fingers to spread it around the walls of her orifice. Then he penetrated her with the breadstick, pushing the soft firm stick as deep as it could go.

Then he started moving it, in a constant pattern of thrusts, twists and pulling out. The butter lubricated the tight orifice, making the task much easier; he could go faster and faster, and he did. Kendra heaved up and down like a ship caught in the storm, her breasts rolling like the tides. She had massive pleasure, from the feeling of such a large rod stretching her tight asshole in all directions, making it sore but in an enjoyable way. Seth also felt a perverse pleasure, from being able to give his sister such joy.

After a few minutes of this, Kendra gasped, "Seth, stop... I can't-"

"Sure, sis." He pulled out the stick, then softly put it back it, cleanly wiping off all the leftover butter with the other end of the stick. Not knowing where to put it, he just chucked it away.

"It's time for the main event," Seth said, flipping Kendra on her back, then getting on top of her, straddling her with wrists and knees. With his hand, he lined up his cock with her snatch and plunged down, forcing the tip of his meat stick into his sister's vagina.

It went pretty deep before he met unexpected resistance, which he pushed hard against, but couldn't break easily. He decided this was the furthest he could go for now and started to rut her, establishing a pattern. In, out, in, out.

"Fuck..." His sister's raw pussy was unbelievably tight. It latched on to his cock, pressing hard on every inch of his skin, stimulating every single nerve on his erect member. Initially, as he moved, it was slow going, but her femcum and his spurting precum made matters easier.

He began to accelerate. Her pussy literally moved with him - as he pulled back, he saw her vulva being pulled slightly away from her crotch, before it let go of its vice like grip and he slid back to a shallower spot. The tight sheath of skin clung tight and was stretched out as he pulled back.

Kendra felt massive pleasure from getting fucked by her own brother. His distended cock expanded her vagina in all directions, and as his foreskin rubbed against her walls, it fired every nerve ending in the region, sending a huge rushing of sensation to her brain.

She groaned. "Faster.."

Seth took the cue and started drilling her like his life depended on it. He pounded and pounded, slamming Kendra into the mattress so hard that the bedsprings squeaked. Mesemerised by her huge jiggling breasts, he started toying and fondling them.

"Aaaaaaarrrrggghhh..." his cock was absolutely massive. It expanded her passage like a blown up balloon. He relentlessly pumped in and out of her core like a hydraulic piston. With the efficiency and power he put behind each stroke, Kendra felt like she was being fucked by a machine instead of her brother.

"More.."

Seth jackhammered his sister. Then he did something unexpected - he reached down with both hands and started stroking her clitoris while he fucked her.

She howled, the cry of pleasure echoing around the room, and her whole body spasmed. Seth pounded on, but he wasn't close to cumming yet. He thought of something.

Seth turned around, his whole body spinning, using his cock as the line of rotation. His cock twisted in her, screwing her, while his body pivoted around and came back to face her. After a few more times, he was close.

"Gonna cum.."

"Not in me, Seth, pull out-"

A lot of things happened at once.

Her pussy went into orgasm mode, contracting around his cock, trying to milk his cum. The spasms wracked her whole body. At the same time, the dam holding back his cum broke.

He yanked out, and started cumming the moment his tip left her. He rushed upward, trailing his meat across her mons, belly, between her breasts and into her mouth. The milky, viscous liquid spurted a line over her chest, but he kept most of it in before reaching her mouth.

Kendra accepted it and sucked, her cheeks swelling to take in the barrage of cum fired into her mouth. A few moments later, she stopped and sucked off the tip to clean it, then tasted some. She frowned, then gagged and spit, letting it trickle out onto the bed.

"Good night, sis."

"Good... ni-"
