Tom Allison: Wild horny sister

"Oh, Jesus!" Katy gasped. "Phil!"

"What are YOU doing in here?" Phil said. He shut the door behind him and stepped towards the bed. There was a deep blush of anger and embarrassment in his face as he glanced between her and the open trunk in the closet. "What gives you the right to barge into my room?"

Katy thought quickly, and decided that her best defense was a good offense.

"Well, what gives you the right to have a dirty magazine collection?" she asked sassily. Katy zipped up her jeans as quickly as possible and rose brazenly to her feet. "Huh? How long have you had these dirty magazines, Phil, huh?"

The anger in Phil's face was quickly replaced by fear. "You have no right to come in here," he repeated helplessly. "That's my private property."

"Private property, huh?" Katy waved the magazine in front of her as she advanced toward him. "Well, what would Mom and Dad think of your private property, Phil, huh? What do you think they'd think of that, huh? So there!"

Phil looked suddenly anguished. "Please don't show them. Please."

"Well, don't give me any more stupid lectures about not coming into your room. Okay? I mean, I'm not supposed to come in here, but you're not supposed to have all these magazines, and if Daddy knew about it you'd probably get grounded for the next ten years! So don't start yelling…"

Then Katy happened to glance at the crotch of her brother's pants, and her girlishly defensive monologue ended immediately.

Her brother had a hard-on. It was difficult to tell in such baggy pants, but there was no mistaking the thick, long column sticking out of the crotch. Katy's eyes bulged as she watched the big cock pulse luridly in his pants.

"Please don't tell," Phil whispered hoarsely. "They'll kill me. Please…"

Katy dropped the magazine and stepped closer, staring openly at his swollen cockbulge. "You really don't want me to tell, Phil?"

"No, please!"

Katy pouted. "Well, then you gotta do something for me!"

"Don't blackmail me!" Phil said angrily. "Not like the time I came home drunk and you made me do your homework! You little bitch!"

Smiling shamelessly, Katy interrupted her big brother by falling to her knees before him. She slid her hands up his thighs and made his gasp as she cupped his stiff cock through his slacks.

"Phil, why is your cock so big and hard?" she asked huskily.

Phil gaped at her silently. Hungrily, Katy kneaded and squeezed his cock through his pants, feeling her pussy burn as she felt the hot stiffness of the cock column on her fingers.

"Those dirty, magazines really turned me on, big brother," she mewled. "I wanna see your cock!"

Phil just stood there and quivered as his baby sister unzipped his pants. Then she pulled them down to his ankles, leaving his nakedness concealed only by his shorts.

The cotton of his jockey shorts was stretched obscenely by his swollen cock, and she could clearly see the fat shaft and spongy, heart-shaped cockhead. Katy's pussy started creaming. Her fingers shook as she pulled off his underwear. Free from confinement, his big prick leaped out and throbbed and jerked in mid-air.

"Oh slit, Katy!"

"God, Phil! You've really got a boner!" Katy whimpered. "It's even bigger than the pictures in the magazines! Oh fuck, your cock really turns me on!"

Eagerly, the horny girl slid her hand up her brother's hairy, surprisingly muscular thigh. Her fingers dug into his ball bag, feeling the twin globes there, clotted with a heavy load of cum.

Phil winced as his cock twitched and jerked excitedly up and down. Delicately, Katy ran her fingers up his cock shaft, pinching the tip. She lifted the crown of his hard-on and stared hungrily at the even bigger-looking underside, at the pulsing vein that seamed his cock.

"Katy, don't do this to me," Phil said helplessly. "You're my kid sister!"

"I know who I am. You don't have to tell me!" Katy wrapped her little hand around the base of his cock and squeezed tightly. Immediately it started to pulse and jerk lewdly in her fist. The bloated, shiny-skinned prick knob loomed in front of her face, and a glistening drop of pre-cum appeared on the piss slit.

"Phil, do you jack off when you look at the pictures in your dirty magazines?" Katy asked innocently. "Do you jack off a lot?"

"Katy, for God's sake."

Katy squeezed his prick hard. "Answer my question or I'll tell Mom and Dad!"

"I… I do?" Phil stammered. "That's what I have them for."

"Like this?"

Giggling hornily, Katy pulled up on his cock shaft, dragging the loose flesh with her hand. She pushed her fist back down, seeming, to stretch the skin on the mushroom crown of his prick.

Phil gasped and did nothing to stop her. Katy started to beat her big brother's cockmeat, moving her fist in a blur up and down the rigid stalk of cock flesh.

"Katy, oh Christ!"

"Fuck, your cock's getting even stiffer! It's getting fatter, too!" Katy's pussy was a slick, foaming pool of lust as she gave her brother a hand-job with growing speed and expertise. "Do you like the way I jack off your cock, big brother?"

Phil only grimaced and started working his ass cheeks, fucking his prick through the tight grip of her fingers. Kath noticed that more and more hot drops of pre-cum seeped from the tip of his cock.

"What's all this stuff coming out of your dick? Does this mean you're going to cum?"

Phil was too horny to reply. Bending her head forward, pumping furiously on his cock, Katy extended her tongue and pressed it to the blood-swollen head of his cock. She wiggled her tongue onto the cum slit, lapping up the juices oozing from his balls.

"Fuck, that really tastes good!" she exclaimed. "It's all thick and musky! Is it gonna taste that good when you cum?"

"Nnn!" Phil's bespectacled face was a mask of incestuous desire. "Suck it, Katy! Just like in the magazines! Suck off my prick!"

Katy flared her nostrils for air and pressed her lips to the pulsating tip of his hard-on. Tentatively, she kissed it, feeling her cunt throb and juice much harder as she got her first real taste of cock.

The cock was delicious; she was hornier than ever to give her brother a blow-job. Opening her mouth widely, the horny girl made a wet, gurgling sound as she took the knob of Phil's prick between her lips.

She closed her mouth just under the crown, forming a tight, compressed circle with her lips. Then she swirled her tongue all over the puffy prick knob, tasting her first wick. It was delicious!

Katy's clit started to tingle as she tongue-brushed her brother's prick, tugging on the fat cockshaft with her lips. She didn't know what to compare the act of cock-sucking to except suckling her thumb as a little girl. Except this big, stiff prick shaft was a lot larger than her thumb had ever been, and she had never derived as much pleasure from thumb-sucking as she did from this fat cock clogging her mouth.

Katy shut her eyes, concentrating on the taste and fullness of the cock in her mouth. Then she sucked in hard, making an obscene slurping noise as her cheeks fucked and her lips dragged tighter around his stiff prick.

"Unhh! Don't bite it!" Phil gasped. "Don't use your fucking teeth!"

Katy folded her lips over her teeth, giving her mouth a strange shape as it luridly embraced the meaty thickness of her brother's cock. She sucked again, slurping less loudly, making Phil's big fucker throb wildly in her mouth.

More cock juice oozed from the tip; Katy rolled her tongue around the prick tip to lap it up. Then she sucked again, and again, until she was giving him a feverish blow-job, holding his cock in position with her fist so she could pleasure the crown with her mouth.

"Unh! Oh fuck, Katy!" Phil stared down at the spectacle of his young sister sucking wetly on his prick. "You're giving me a blow-job! I can't believe this! Ohhhh, fuck!"
