"Fucking bitch!" He wanted to fuck her long and slow, but now she would have to pay for that. He forced her legs apart and thrust his cock in between her thighs. Anne fought and twisted, kicking with her legs, trying to break free, to not let him inside of her again. He grabbed both her legs behind the knees and pushed her wide open. In one thrust, his cock found her opening and buried itself deep inside. She screamed in terror more than pain as Mark wrapped his arms around her shoulders and ground her body into his own. Her cunt was still slick from the last fucking, and burying his face in her hair, he began to brutally pound into her.

Anne grunted as she took each stroke, one direction filled completely, another nearly emptied. Mark was in pure heaven as he attacked her cunt like a wild animal. He could feel her hot body beneath him and was slightly sad that he couldn't feel her bare breasts against his naked chest while he fucked. Oh well, plenty of time for that later. For now, he fucked her like a man possessed.

Anne closed her eyes and tried to be far away, but the pounding cock in her pussy kept her too close to reality. There was nothing she could do this time. Pinned beneath her brother, her legs spread wide while his hips and ass pumped in and out of her, she couldn't even move, let alone try to help the process along. It didn't matter, though. Within minutes she heard him grunt and felt his entire body stiffen as his cock plunged in to the hilt. She felt his hot cum fill her pussy for the second time. Mark grunted again and moaned with pleasure.

His cock twitched and spasmed inside her. He just fucked his own sister for the second time in one night! He started laughing to himself and unceremoniously rolled off of her. Anne remained on her back, eyes closed, breathing heavily.

"That was good," he laughed, turning his head to look at her. Her nose crinkled in disgust. "As a reward, you may have half an hour for yourself to take a shower and get cleaned up." She looked over at him and sneered, but got to her feet and headed thankfully to the bathroom. "And Anne," he said a s she reached the door, "make sure your dressed again properly when you're finished." She didn't even turn to look at him as he spoke, only nodded and continued on.

Marked lounged in bed, humming idly to himself, as he heard the water start to run. He smiled happily. This was going to be a great weekend. No doubt Anne would use the entire half-hour, but that was okay. He was spent for the night, and content to merely lay back and recall all the wondrous things he had experienced that day.

The ringing phone cruelly snapped Mark out of his revelry. He rolled over and reluctantly picked it off the receiver beside his bed.

"Hello?" he half snorted.

"Hi, is Anne there?" Marked ground his teeth. He recognized the voice. One of Anne's friends, one of the girls who weren't supposed to call this weekend.

"No, didn't she tell you she went away for the weekend?"

"She said that she might be, but wanted me to call her tonight to make sure."

"Oh, well I'm sorry. She's gone until Sunday night."

"Okay thanks, bye." Mark slammed down the phone. That bitch! She would pay for that one, too. Mark jumped up and started for the bathroom, then stopped. An idea filled his head, and idea so much better than another hard fucking. He threw on a pair of shorts and headed downstairs to prepare.

Anne turned the water off and stepped out of the shower only with the greatest of grievances. Disgust ran through her body. She had allowed her own brother to fuck her, to cum inside her mouth and pussy. She had almost scrubbed herself raw, trying to wash away the filth she felt inside. It didn't help. She glanced at the clock and sighed. She had only five minutes left. After seeing what Mark was capable of, she didn't want to risk any of his wrath by being late. After drying herself, she pulled back on the sleazy French-maid outfit and brushed out her hair. She slowly opened the door and looked out. Mark was not in sight. She sighed and headed slowly for his room.

"Anne, come down stairs, please." The pleasantness in Mark's voice reminded her of a snake about to strike. But she found that her feet were already heading down the stairs. She passed down the hall, but he was nowhere in sight. When she rounded the corner into the living room, her eyes fell on the old, wooden armchair that used to be in the dining room. She noticed that several straps had been attached to it. Before she could think about the strangeness of it, she felt a pair of hands grab her from behind and toss her roughly to the floor.

Stunned by the sudden attack, she was too dazed to react when Mark grabbed her again and hauled her into the chair. She thought about fighting back, but before she could react, Mark had already fastened one of her arms securely in place. She jumped at him, swinging her free arm wildly, but Mark had already forced his weight into her. Practically sitting on her, he forced her other arm down and tied it securely. Once in place, she gave up. Her legs were tied at the ankles and knees, forcing them apart, and another strap was secured across her waist. She was his captive, beyond all doubt.

Mark towered over her, staring down.

"One of your friends called while you were in the shower," he said, shaking his head. "I'm so disappointed in you. Well this is what happens when you cross me." He bent down and kissed her hard on the lips before he slipped a black pillowcase over her head. He secured it around her neck with a small belt and patted her on the top of the head.

"Night, night, Anne," he laughed. "Sleep tight."

Mark slept in late through the morning. He lounged in bed, lazily stretching and twisting as images of his dream-like night filled his waking mind. He felt a brief moment of guilt, not just for the forced sex, but also for having sex for his own sister. But that brief moment of guilt was quickly and utterly replaced with a stirring lust. He smiled and headed down the stairs naked. He found his sister still tied to the chair, her head slumped to one side in what was no doubt an extremely uncomfortable position. He could see the curves of her body through the tightness of her outfit.

He knelt down in front of her and placed his hand on his sister's knee. She didn't stir. He smiled lifted up her skirt, getting an eye full of her sweet pussy. It looked so thoroughly delicious as he slid his hand down her opened thigh and gently rubbed the lips. Anne shivered and stirred at his touch, her head rolling forward as consciousness grabbed her.

Anne groaned as the stiffness of her neck shot slivers of pain through her back and head. She slowly opened her eyes and started to panic as a strange darkness filled her vision. Slowly she calmed down as the events of the past night caught up her. She remembered the fucking, the humiliation, and finally being tied to this chair and left there all night. It had taken her hours to try and fall asleep, and at last exhaustion found her. It had her still, but something had awakened her, was keeping her awake. And she felt it in her cunt.

She soon became aware that she was not alone. It was Mark, she knew, that was kneeling before, one hand massaging her thigh, the other plying at her cunt. His fingers rubbed around her lips, moving slightly up to tweak at her clit, and back down again to slowly push into her abused hole. Had this been anyone else, under any other circumstances, she would be enjoying herself greatly. But even with the intense stimulation, she refused to acknowledge pleasure.

Mark could take it no longer. It just looked so good, he had to taste it. He reached around and untied the belt at her waist and pulled at her hips. She had enough slack to allow her ass to be dragged to the edge of the chair. Mark wasted no time. His hands firmly gripping her hips, he plunged his face in between his legs. His tongue snaked out, lapping and licking at the lips of her cunt. She tasted good, so good he forced her lips apart and sank his tongue deep inside her. Anne moaned and twisted in disgust and helplessness. She knew at that moment that her humiliation could not get any worse.

Mark would have been quite content to sit before her and eat out his sister all day, but he only had a weekend. And after he was through with her, he knew that he would never have a second chance. He had to make the most of it. Reluctantly, he took one final lick and pulled back. His hands slid form her hips and moved up her sides to cup themselves around her breasts. He suddenly realized that he had yet to see her tits and give them the proper attention they deserved. He smiled at his own neglect. Grabbing the top of her blouse, he yanked, shredding the thin material and pulling it to the side.

Anne jumped in surprise, feeling all the more vulnerable. He stared at her tits, marveling at their curves, at the small, perky nipples, the full, firm shapes before his hands cupped the naked flesh for the first time. His hands and fingers roamed and probed and squeezed at her tits with abandoned lust. They were simply marvelous. He bent his head forward, burying his face between the mound and squeezing the flesh into his cheeks. His mouth locked onto one nipple, sucking and biting until it hardened. He slobbered and kissed at it, leaving a glistening trail as he licked across her chest to the other.

Anne remained silent, trying to keep emotionless to the attack on her helpless body. She had only to get through one ore day of this and it would be all over. She could endure one more day. She sighed in relief as Mark finally gave up on her tits, leaving them wet and sore, and started to untie her. She stretched her cramped and aching muscles as he pulled her to her feet. She moaned and stretched and reached to pull off the makeshift hood, put Mark grabbed her arms to stop her.

In one, shift motion he pulled at the flimsy material of her uniform and tore it free, leaving her blind and completely naked before him. Mark dragged her by the shoulders to the couch and tossed her to the floor. She lay there, uncertain of what to do. She was more vulnerable than ever and knew she couldn't fight off her bigger brother, especially like this. Laying on the floor, slumped against the couch, she refused to move. Her aching muscles fought against her, fought against the torment of the night in the chair.

She suddenly felt herself being bent at the waist over the couch. A strap was attached to her right knee and pulled taunt. Another was attached to her left, leaving her kneeling, bent over the couch with her legs forced apart. She didn't bother to struggle when she felt the same being done to her wrists. When he was done, Mark had her secured to the couch in perfect fucking position. The tension on her arms caused her upper body to be stretched and lifted off the couch. When he knelt down behind her, he discovered, much to his delight, that her tits were open and free to be fondled from behind. He positioned his cock at her pussy lips and eased it inside of her.

Mark groaned loudly in her covered ear as his cock, greased with his own saliva and her natural lubrication, slide deep within her. He buried himself to the hilt. He could feel the walls of her pussy spasm around his shaft. He remained within her, enjoying every sensation, for several minutes, his hands working over her breasts. Slowly, he eased himself back out of her until only the head remained inside. Holding her firmly, he slammed back into her. Anne grunted and bit her lip to keep from yelling out.

Mark smiled and licked her shoulder as wave after wave of intense pleasure coursed through his dick. He growled playfully to his helpless victim and eased his cock back out, only to slam it in again. Over and over, with an ever-quickening pace, Mark battered his sister's ass cheeks, filling the room with the smacking of skin on skin, his hands never leaving her breasts.

For half and hour he rammed his sister's cunt, mauling her body with his hands, abusing her with his cock. He was going to cum inside her pussy soon, but that wasn't what he wanted this time. He wanted her to swallow his cum again. She had given him a fantastic blowjob last night, even under order. He couldn't wait to do it again. He pulled from her in one, swift jerk, a wet, slurping sound accompanying his exit. He started to stand and when her looked down at her ass.

It was a shame to leave her pussy empty while he filled her mouth, he thought. An idea filled his head and he left the room. Anne struggled to hear what was going on, to discover why he had suddenly stopped. She thought she heard the back door open, and Mark talking, but she could not make it out.

She could feel Mark walk back into the room and stood beside her, chuckling to himself. She thought she could hear a patting sound and suddenly felt hot breath on her naked pussy. She jumped, feeling Mark sill standing beside her. Someone else was in the room sniffing at her cunt. Had Mark invited a friend over to abuse her as well? She tried to twist and fight away from the loud sniffing and hot breath that followed her every move.

"You're going to love this, Anne," Mark smirked at her. She felt a wet tongue lap across her pussy lips and jumped. The tongue felt huge. It seemed to cover her entire cunt with each lick. Anne had never felt a guy eat her out like that. The huge tongue licked forward and filled her up like a cock.

Anne squealed into her hood as she felt coarse hairs rub against her inner thighs. Whoever was licking out her pussy was doing a job like no other. She couldn't help but to feel her body become aroused as her new assaulter slobbered and panted around her cunt. Her arousal turned quickly to fear and disgust when the sudden realization struck her. It was not a who but a what that was licking her. And that what was a dog.

Mark grinned as Anne shrieked and tried to pull away from the lapping dog. Prince, their massive German Shepherd, followed her every move, lapping away at the delicious cunt.

"Good boy," Mark praised as he patted the dog's head. Prince ignored him, intent on his task at hand.

"Mark, no!" she wailed as the dog continued to assault the captive girl's cunt. She began sopping, the depraved act robbing her of all of her dignity.

For several minutes Mark just watched in wonder as Prince licked his sister. Anne had stopped sobbing, and was now grunting with each lick. He listened carefully and could have sworn that the grunting was from pleasure, not humiliation and torment. He smiled and stood up. Anne could feel the belt around her neck loosened and the hood was pulled off. She squinted as the sudden morning light stung at her eyes, but her vision slowly adjusted. She looked behind her as best she could and watched in wonder and horror as the big dog ate her.

Mark climbed up on the couch and squeezed himself in between her and the back of the couch. Anne opened her eyes as Mark grabbed the sides of her head and pulled her mouth down on his cock. Her mouth resisted for an instant before he shoved the cock head, and the rest of the shaft, inside. He forced in as much as he felt she could take and started pulling her head up and down on his penis, jerking himself off with her mouth.

Anne closed her eyes as the sensations between her legs betrayed her mind. It was good. She had never in her young life been so thoroughly pleasured orally by anyone. She pretended it was someone else, and not her pet dog, that was eating her. She pretended it was Dave. Her mouth slowly relaxed at the thought. As for the cock in her mouth, it didn't really matter. She liked giving head, and as long she pretended it wasn't her own brother, than it was all right. As he pulled on her head, Anne moaned softly and started to suck back, her mind lost to the realization of what was happening to her. All that mattered was that she was getting the pleasure of her life.

From his vantage point, Mark had the perfect view of Prince licking his sister with his massive tongue. The sight turned him on beyond compare. As he fucked Anne's mouth, the idea of her totally humiliation brought him closer and closer to orgasm. After the wonderful fucking he had given her already, he was close. So when she actually started to suck him back, Mark could not control himself. In a rush, Mark grabbed the back of her head and forced it down on his cock. Hot cum erupted in her mouth. She didn't have to be told this time as she swallowed every drop. Mark held her head tight, not letting his softening cock out of her mouth.

Anne could feel her it deep in her cunt, the growing sensation of orgasm. She fought against, fought the betrayal of her body. She didn't want to cum by a dog's tongue. When Mark's cum flooded her mouth, however, the fire increased a hundred-fold. She swallowed his incestuous sperm eagerly. She closed her eyes tight as Prince continued his vicious licking. Anne suppressed a deep moan, letting out a quiet whimper as wave after wave of intense, animal sexuality rushed through her body. She wanted to cry, to scream, to holler at the top of her lungs, but she wouldn't give Mark that kind of satisfaction. She whimpered, his soft cock still in her mouth, and did all she could to keep from biting down.

The dog lapped at her flowing cum until he was satisfied and, tail wagging, went into the kitchen. Mark groaned, having just witnessed the most erotic event he could ever imagine. Smiling lazily, he pulled himself off the couch and, patting Anne on the head, went upstairs to shower.

Anne slumped against her bindings. They stretched at her arms and shoulders, but she was too exhausted by the whole ordeal to care. How could her body betray her so completely? How could she get off on a dog licking her cunt? It had been good though. So good...
