Marvin Cox - The naughtiest sister

"Goddamn you, you fucking cocksucker," he grunted, his face contorted with pleasure. "Suck me! Come on, you little cum-sucking whore… suck!"

Susan held her mouth wide open, letting him do all the work. For several moments he jammed into her throat like some crazed animal, continually shoving his cock with lightning-like strokes. When his cockhead slid across the roof of her mouth and over her tongue, she could feel the vibrations of ecstasy filter through her pussy. Her clit grew rigid, then began throbbing, sending waves of delicious jerks down the insides of her thighs. She rubbed her knees together and felt the first hot jolt of release sear her cunt.

She choked, baring her teeth and scraping them up and down his plunging shaft. Another thundering explosion of climax shot into her body, making her thrust her head upward.

"Hold on, baby." Brian grunted. "You'll get it… in a second. And when I blow my fucking load, I want you to gargle it down like a… unh… good girl!"

Susan reached between his legs and dug her nails into his bobbing ass, rubbing her fingertips into the hot, hairy crack. She was peaking, her pleasure becoming all-consuming. Nothing in the world now could possibly make her feel better than a thick lump of cum.

He gave a low panting groan of pleasure and squirmed his ass around, grinding the base of his cock between her lips.

"Baby… baby," he whispered. "So fucking good!"

Susan opened her throat completely, allowing the thick lump of cum to drain into her stomach. While it warmed her insides, she worked her tongue around his shaft, capturing the slick residue that bubbled inside his foreskin. When he was clean, she nudged her head aside and pushed him away.

"Now fuck me," she whispered. "Fuck me like a little dog!"

She got to her knees, supporting herself on her elbows, and looked over her shoulder, wagging her ass. She grinned seductively and ran the tip of her tongue over her teeth.

Brian knelt behind her and pushed her legs further apart with his knees. He ran his hands up the insides of her thighs and rested his fingertips in the crack of her pussy.

"You sure I'll even fit in here?" he asked. "Jesus, you've got the tiniest pussy I've ever seen!"

"It'll fit," Susan replied. "I'll make the motherfucker fit or die trying."

Brian placed his cock between her legs and rubbed his engorged cockhead between the slick puckered lips of her cunt. His dick was immediately engulfed in a pulling warmth, almost as hot as her mouth. He held her hips and squeezed in about four inches of his shaft, then remained motionless for a few seconds.

Then, when he couldn't take the agonizing torture any longer, he increased the speed of his fucking. He felt his sister's pussy constrict, sucking on his shaft like a hungry mouth.

The thought of her brother fucking a another girl filled Susan with hungry desire. She could almost imagine what it would have looked like, his huge frame engulfing her tiny body, his gigantic cock ripping into her guts. She shivered with anticipation, knowing that she, too, was getting the same thing that little girl had gotten.

"Give it to me, stud," she moaned, her voice quivering with lust. "God, fuck me hard! Fuck rue just like you did that little girl! Bang my pussy into a million pieces!"

Brian dug his fingers into the soft flesh of her hips and began, drilling in and out with savage strokes. He increased his speed, devoting every bit of his energy to battering her cunt to hamburger.

His face was contorted in a wince, his breathing rapid and low, his nuts swinging back and forth like a pendulum.

"Take it, cum," he spat. "Goddamn you, take my dick."

Susan felt a hard throb begin to swell in the back of her cunt. The buzzing inched forward until a quick spasm tore at the outer folds of her pussy. She inhaled loudly, then began shaking all over matching the rhythmic plunges of his huge cock.

"Yes!" she cried. "God… God… yes! Give… it… to… meeeee!"

Brian fucked furiously into her pussy with such speed, his entire body was like a jack hammer. He wanted desperately to hold back for a little while longer, but it was useless. His nuts were boiling over with a thick, lava-like lump of cum. He felt it explode into the base of his cock, the squirt violently up the center of his shaft. When the first blast of cum erupted from the end of his prick, then he slammed his full weight forward, grinding into her cunt with animal-like brutality.

"Fuck!" he grunted. "Goddamn you; you fucking big cocksucking whore…fuck! Unh! Fuck! Fuck!"

Susan's orgasm peaked just at the moment when she felt his cock empty into her cunt. Hot spasms drilled up and down the length of her pussy canal with unbelievable force, causing her to shudder.

"All of it!" she begged. "God, fuck me full of his greasy cum! Give it to me, you fucking bastard! Oh! Oh! OHHHH!"

For several long moments they both bucked and squirmed around, gasping and groaning as spasm after hot spasm gripped their insides. Finally Brian plowed in the last of his load, then relaxed, biting the back of her neck. He continued moving his prick in and out of her frothy hole, however, until he was sure that every drop of jism had oozed from his cock.

Susan was exhausted but still filled with a growing hunger. She moved her ass around and slipped her fingers down the sides of his body. Reaching between them, she touched the sticky taste of his cock, puffing some of the spilled juice over her ass.

"Let me suck you again," she whispered. "I want to eat some more of your sweaty dick."

"Damn, I've never known a girl like you before," Brian said. "You really do love dick, don't you?"

"Let me show you, little brother," Susan whispered.

"You do that, baby," Brian said, pulling her to his side. "Then I'll show you a thing or two."

"Or three… or four," Susan grunted, placing his cock into her mouth. "Mmmmmmm… or even five or six!"

Susan stood outside Gary's bedroom door, her hand on the knob. When she heard muffled voices, she leaned her head closer.

"I'm just scared, that's all," came a young feminine voice.

"Don't know why," Gary answered. "It won't hurt. Well… much, that is."

Susan grinned. The conversation she was overhearing had happened to her once – almost word for word. She knocked gently on the door and went inside.

"Oh, hi, Sis," Gary said, quickly getting off the bed, color rising in his cheeks. "I… I thought we were alone in the house."

"So I can see," Susan said, sitting down on a chair by the door. "Who's your friend?" she asked, smiling at the young blonde girl.

"Georgia," Gary said. "Like the song – Sweet Georgia Brown." He gave Georgia an affectionate look and again his face turned beet-red.

Susan quickly understood why Gary was so obviously fond of the girl. She was tall, still a teenager, but had the body of a twenty-year-old. Her enormous tits were well shaped and came to two upturned points, giving her slim waist the illusion of being even smaller. Her hips were rounded and full, leading down to shapely tanned legs. Her eyes were hazel, large and expressive. Wearing an emerald green jumper and a pale shade of peach-colored lipstick, she was the epitome of youthful beauty.

"I couldn't help overhearing," Susan said after the introductions were over. "Perhaps I can be of some help…" She let the inflection in her voice drop to a whisper.

Gary looked as if he'd been slapped. He glanced over to Georgia, then to his big sister. There was a long moment of silence before he swallowed hard, then spoke: "I… I don't exactly know what you're talking about," he said. "We were just…"

"You were just trying to deflower Georgia," Susan said, her voice calm and reassuring, then to the young girl she added, "to you want to do it?"
