As the humiliations perpetrated on her grew worse, the shy little blonde found it even more impossible to tell anyone about what was happening. How could she possibly face anyone and tell them that boys had fucked her in the ass? She just couldn't. All she could do was pray that Kim went away and left her alone.

Her sister  had no intention of doing this, of course. She enjoyed terrifying the blonde girl, reveled in degrading her and showing her who was boss. It excited her and turned her on more than anything she'd ever done.

When she found Amy's door locked the next afternoon she pounded her fist on it hard.

"Open the door!" she ordered.

There was no answer from inside, where the blonde cowered behind the door.

"I said open this fucking door you little cunt! Otherwise I'll break it down and kick the shit out of you!"

There was still no answer.

"Last chance, sister bitch! Then I'm gonna kick your ass!"

There was a clicking sound and she turned the knob and opened the door. Amy stumbled back, her eyes wide and fearful.

"Took you long enough," Kim sneered. "I think I deserve an apology for you making me wait outside."

"I...I'm sorry," Amy gulped.

"You sure are, slut. Take your clothes off."

"Kiimmm."

"Don't whine, sister bitch, or I'll kick your cunt!"

Terrified, Amy slowly took off her clothes, blushing as her sister looked on with a smirk. When she was naked she stood there, crouched, her hands trying to cover her breasts and pussy.

"Stand straight and put your hands down," Kim snapped.

Hopelessly, Amy obeyed, her face red.

"Get down on your hands and knees," Kim sneered.

Amy slowly dropped to her knees, then onto all fours. She stared down at the floor, trembling slightly in fear.

"Crawl forward. Crawl over to me," Kim ordered, grinning in enjoyment.

Amy slowly crawled forward until she was right in front of her sister, then waited, still trembling.

"You know, my boots got kind of dirty today," Kim said. "They sure could use a good cleaning."

Amy said nothing.

"I want you to clean my boots off, slut...with your tongue," Kim sneered.

Amy raised her head slightly and looked at the dirt encrusted combat boots with a fearful whimper.

"Now, slut! Or maybe you'd rather turn around and see how far up your cunt I can shove my boots!"

Terrified that her crazy sister would actually do something like that, Amy lowered her face towards the boots, but still hesitated to touch them with her tongue.

"Now! Lick it!" Kim snarled.

With a gasp of fear the little blonde pushed her tongue out and licked the top of Kim's right boot. She licked the dirt off, tasting it in her mouth and trying to ignore it. She licked all over the top of the boot, then along the sides and ankle as Kim stood there sniggering and chortling in glee.

"You can use your hair to wipe them too," Kim sniggered after a few minutes. "Go on. Scrub it with your hair."

Amy was glad to. She bunched up her long hair and used it as a scrub brush on Kim's spit wet boot.

Kim got tired of standing and sat down, crossing her legs and holding up the bottom of her right boot. Cringing inwardly, Amy was forced to lick the bottom of the boot, then scrub it with her hair. When she was done with that boot she had to start over on the left.

Finally, with both scrubbed clean, Kim stood up.

"Wait there," she ordered.

Amy obeyed, grateful that, at least up until now, she hadn't been hurt. She tasted dirt in her mouth, and her hair was filthy, but a little shampoo and toothpaste would take care of that.

Kim came back with a small can of something, then sat down in front of her again. She held the can out to her sister and Amy took it warily. It was boot polish.

"Go ahead, polish my boots," Kim demanded.

Amy opened the can and looked at the black polish, then at Kim's boots.

"I...I don't have anything...I mean...I don't have a rag," she gulped.

"And your hair is all dirty," Kim sighed unhappily. "Well, that's all right. Use your tits."

"My...my...what?" Amy blinked.

"Use that fat tit meat of yours, slut," Kim leered.

"I...I don't know..."

"Grab a tit, rub it against the polish, then use it on my boot, you dumb cunt!"

Amy held the can in one hand, then squeezed her right breast and rubbed some of the balled out flesh against the can of polish, then put down the can and held her sister's boot as she rubbed her soft breast over the side.

It worked, she saw, as she spread the polish up and down the side of Kim's boot. She stuck her breast in the can again and once more rubbed against the boot, ignoring Kim's giggles and snorts of amusement. She didn't care what she had to do, just so long as it didn't hurt.

"Use both tits, sister bitch! Rub the polish all over them."

Amy knelt there with Kim's booted foot between her breasts, rubbing them both against the sides as she spread the black polish all over. She didn't look up at Kim's face. All she cared about was finishing this as soon as possible. Maybe Kim would leave then.

"Good enough," Kim sighed negligently. She put her foot against Amy's chest and shoved her back hard so she fell back on the floor. She undid her belt and jerked her loose pants down and off, then spread her legs wide and patted her pussy mound.

"Come and lick me, whore," she ordered.

Amy whimpered, but got back to her knees and licked her lips anxiously.

"Kiim," she whimpered.

"Want a spanking?"

"No."

"Do it then, whore!"

Amy had no choice but to lean in and begin to lick at Kim's pussy slit. Under repeated snarls and slaps she began to dig her tongue deep between the folds of the other girl's pussy lips, slurping and sucking and lapping at her sister's pussy hole as Kim slumped down and raised her legs high and wide.

Kim sighed in pleasure as her sister tongued her slit and sucked on her clitty. She laid her head back and let the pleasure wash over her, humping up slowly into Amy's soft face as the girl's small pink tongue worked at her moist fuck opening.

"Dirty little whore," she sneered. "Weak, good for nothing shithead! I oughto sell you to the pimps on Market street. I could get good money for a big titted whore like you. All those nigger pimps would love fucking a dirty little blonde whore.

"Ooohhhh! Yeaaaahhhh! Theeree! Lick me theeerre! Ooohhhhhhhhh! Uhhhhhhnnnnn! Ungh! Ungh! Ungh! Ungh!"

She jammed the blonde girl's face into her pussy as she humped up faster and faster, the blood boiling within her as her fuck box began to burn and sizzle with sexual heat and fire. She panted for breath, gritting her teeth as the power grew and grew.

Then she arched her back and groaned in bliss, the orgasm washing over her and setting her body jerking and twitching with convulsive sexual pleasure.

She sighed and slowly lowered her feet to the floor, easing her grip on Amy's hair.

"You're starting to get good at this, slut," she panted.

She pulled her pants on, then stood up and left. Amy stared after her warily. Slowly, a feeling of relief came over her. She had gotten through it without any pain! She crawled to her feet and over to the door, then started to lock it.

She hesitated, then left it unlocked. She didn't want Kim to get mad at her.

She looked down at her breasts, all black and red, then opened the door again and went out into the hall. She went to the bathroom and again took a shower, scrubbing again and again at her soft breasts to get the polish off.

She yelped and tried to cover herself as the curtain was pulled aside and Kim stood there grinning.

"Are we all clean now?" Kim leered.

Amy gulped and stared at her in fear. Kim reached over and turned off the water, then raised a camcorder and pointed it at her, turning on the light.

"Kim!"

"Shut up and take your hands away."

Trembling slightly, Amy eased her hands away.

"Stand up straight. Put your hands behind your head and shove those fat melons out!"

Amy reluctantly obeyed, hoping Kim was just teasing her, that there wasn't any tape in the machine. Her breasts glistened wetly as she arched her back, and Kim moved in for a closeup, running the camera up and down her body.

"Now take the soap and start soaping up again," Kim ordered. "Soap up those fat titties."

Amy obeyed her, trying not to look at the camera as she ran the soap up and down her chest and stomach, still cringing a little, instinctively. She soaped up her breasts and belly and crotch slowly.

"Turn around and bend over and spread your legs."

Again Amy obeyed. She knew if she didn't Kim would hurt her and make her do it anyway. She turned and bent over and spread her legs, not looking back, knowing Kim was focusing on her pussy and asshole.

"Reach back and pull your ass apart. I want a good shot of that asshole."

Beet red with embarrassment, Amy obeyed again, closing her eyes in humilation as the bright light shone on her little puckered anal opening.

"Okay, step out of the tub."

"But...I'm...I'm all soapy and wet," Amy said, her lips quivering.

"I said get out!" Kim snarled.

Amy quickly climbed out of the tub and stood next to it as Kim backed up.

"Now sit on the toilet."

Amy turned and sat down on the toilet, looking down at her feet.

"Slump down, slide down and raise your legs up high and spread them apart."

Amy drew her legs up and back, and slid down on the toilet as Kim focused the light on her pussy.

"Okay, now jerk off."

Amy stared at her in shock.

"You heard me. Let's see you jerk off."

"I...I can't," she gasped.

"Do it, whore."

"Pleeease," she said, her eyes tearing.

"Do it, sister bitch, or I'll shove my whole fist up your cunt and rip your guts out!"

"Kimm!"

"Do it!" she yelled.

Kim sobbed, then bit her lip as she slowly brought her hands down on her soapy flesh. The camera whirred, and she no longer had any doubt that Kim was taping this, nor that she would show it to others, maybe Dog and Hulk.

She slid her hand down between her legs and began to rub stiff fingers over her slit.

Amy's trembling fingers rubbed awkwardly along her furry pussy as her sister zoomed in on it. She didn't know what to do. She simply couldn't do such a dirty thing in front of Kim. Even admitting she did it was too much for her.

Yet she feared being hurt, was terrified of making the cruel punk girl angry. Her fingers touched her pussy tentatively, then halted, sort of cupping her pussy mound.

"Come on, slut. Let me see you rub your little clitty," Kim sneered. "Let's see you pump your pussy."

"I...I caaaan't," Amy whined.

"You better, sister bitch," Kim hissed.

Amy stared up at her with wide, frightened eyes, cupping her pussy with both hands, too mortified to obey, too terrified not to.

Kim put down the camera with a mixture of anger and excitement. She wanted to hurt the dirty, big titted bitch, and now she had an excuse, now she could do so with righteous indignation.

She put down the camera slowly, as Amy started to whimper and weep, then she shot her hand out and gripped the girl's hair, jerking her up off the toilet. She slammed her into the counter and bent her roughly over it.

"All right, sister bitch, you asked for it," she sneered.

She backed up and unbuckled her belt, then slid it out of the loops. Amy remained where she had been placed, weeping softly as she clutched her small hands into fists and buried her face in her arms. Kim slid her belt out and doubled it in her hands, then stepped back and raised her hand.

The belt sliced through the air with a vicious hissing sound and cracked across the bent over blonde girl's wet, soapy buttocks with a cutting blast of pain that rocked her mind and drew a scream of agony from her lips.

Amy's weeping became gut-wrenching sobbing as the pain burned her flesh. Yet she made no attempt to stand up or twist away. She stayed where she had been placed as Kim raised the belt again, then whipped it down across her soft round bottom.

Again she cried out in pain, her sobbing rising in strength and misery. The belt cracked down across her buttocks again, then again, then again, each time producing a scream of pain and a fresh burst of sobbing.

Kim felt her pussy burning as the girl screamed and cried. The feel as the belt cut into the soft round ass flesh was indescribably exciting to her. The sight of the red welts across that perfect little ass, and the mere fact that the stupid little bitch didn't dare even try to move away, was producing a huge burst of lewd, cruel sexual excitement inside her.

Again and again she whipped the leather belt down across her sister's upturned ass flesh, as Amy 's sobs and cries filled the air. Then she put down the belt, her own pussy steaming as the trembling, whimpering, sobbing girl lay across the counter.

She slid her hand in between the glistening wet thighs and cupped Amy's pussy mound, squeezing cruelly, digging her fingers into the soapy soft pussy meat and twisting them around.

"Dirty little whore," she sneered as Amy continued to sob and whine and cry out in pain.

She jerked her hand upwards, making Amy's bottom jerk up. She jerked her hand down, pulling Amy's bottom with it. She sniggered as she made Amy's bottom jerk around in circles. She drew her hand back and slapped it directly on the moist pussy pad, then began spanking it, delighting in the feel, in the rush of adrenalin and heat, in the renewed sobbing and moaning from the helpless blonde.

She reached down beside the toilet and picked up the plunger, then pushed the end of the handle against her sister's wrinkled little anal opening. She brutally jammed it forward, forcing it through and into the blonde's ass.

Amy gasped in shock, at last jerking her head up off the counter, trying to push her chest up. Kim shoved her down again, and rammed the plunger in deep, impaling the shuddering blonde girl on the hard wooden tool. Amy cried out as it drove deep into her belly and punched against her guts with painful, agonizing force.

"Ahhhhhhghghh!" she screamed through her sobs.

"Like this, slut?" Kim panted.

She was rapidly fucking the plunger up and down in Amy's asshole, not caring how much it hurt, wanting it to hurt.

She snickered and leered as she raped her sister"s ass as fast as she could, ramming the plunger as deep as it would go, then twisting it around violently.

She considered raping her cherry out, but was saving that for something special. She wished she had a cock so she could fuck it up Amy's ass, or at least a really big, thick dildo. She made up her mind to get one as soon as possible, and rape Amy with it every night. No, she would make her use it on herself.

She jerked the plunger out and tossed it back behind her, then slapped her hand down hard on the still wet, soapy buttocks. She pushed her finger against the trembling, shaking girl's anal opening and screwed it down inside, then added a second, then a third.

She jammed them in then jerked them back, sniggering as she twisted them from side to side in Amy's ass. She gripped the back of the blonde's neck and shoved her fingers in hard, forcing them in to the knuckles.

She pulled them back and pressed all her fingers together, forming a tight wedge, then slowly pushed them forward, spreading Amy's anal opening wider and wider, making her yelp and whimper and whine as her ass stung and ached. Kim screwed her soapy fingers back and forth as she worked them deeper and deeper, grunting with the effort as she tried to work the widest part of the wedge through.

Amy cried out in pain and shocked misery as her anus was spread wider than she'd ever believed possible. Kim's knuckles passed through the opening and slid into her rectum.

"Ohhhh! Ahhhhhh!" Amy gasped. "OOhoooohhhhh!"

"What a tight little asshole," Kim sneered. "I'll have to bring over more of my friends so they can ream it out and make it wider."

She shoved her hand in, watching the tight flesh around Amy's round hole straining and pushing inwards around her hand as she drove it all the way into Amy's rectum. She was fascinated by the feel of the girl's ass, the soft flesh squeezing down around her hand as the entrance gripped her wrist.

She moved her hand around freely inside Amy's ass tube, and continued to push forward, watching more of her wrist slide into the girl's round hole. She continued to twist and wiggle her fingers around as she pushed them forward, feeling the soft insides of her belly, of her guts. Finally she touched what felt like the bottom of the quivering, sobbing blonde's ass tube.

Then she eased her fingers in against the palm of her hand, closing them one by one to form a tight fist inside her sister's guts. As soon as that was accomplished she pushed forward once again, grunting and grinning as her fist shifted deeper and more of her forearm passed through the tightly squeezing entrance to her asshole.

She took her hand off the back of Amy's neck and slapped her bottom hard, producing a cry of pain and a sudden spasming and squeezing sensation inside her ass. Again she slapped her sore, red bottom, jamming her fist in deeper as she did. She felt her knuckles grinding against the deepest pit of her ass, and Amy shuddered as cramps and spasms wracked her body.

She groaned and whimpered and tried to shift herself away, but was caught like a fish on a barbed hook. Her ass was sucking and squeezing on Kim's fist so hard she didn't think she would ever be able to get off of it.

Again Kim's hand cracked down on her buttocks, then again, making the soap shoot out to either side. Kim's own face was almost as red as the blonde girl's buttocks as she slapped her hand down again, then slid her hand up her sister's spine and slowly twined a thick shank of hair around her fist.

She jerked back suddenly, forcing the blonde's head up and back, and at the same time punched her fist in deeper.

Amy cried out in pain as her scalp burned, then cried out again as she was punched in the belly, punched in the belly from the inside.

Kim twisted her fist from side to side, then slowly began to ease it back down the super tight anal tunnel. She pulled back perhaps two inches, then punched forward again, producing a satisfying moan of pain from Amy.

Again she drew her fist back, then punched it forward, then again, then again, forcing Amy's anus wider, breaking down her resistance, numbing her anal muscles as she began to fist fuck the weeping blonde girl's ass.

Her fist moved faster and faster, and she jerked back on Amy's soft hair each time she thrust forward. Her powerful arm churned the dazed blonde's guts into a quivering jelly as Kim snickered and leered in happiness.

The blonde girl was on the verge of madness from the horror and pain inflicted on her. Kim's fist was punching repeatedly into her guts with enough force to knock her upwards onto her toes with each blow. Her whole head felt like it was on fire as Kim continued to tear at her hair. Her heavy breasts slapped and rolled against the counter below her as she was jerked back and forth.

She could hardly breath with the repeatedly pounding against her belly, and finally she simply blacked out, leaving the annoyed Kim with no toy to play with.
