Marvin Cox - The naughtiest sister

The room was silent except for the soft sounds of their breathing. But from the other room came the gurgling noises of a mouth on a cock.

With John's cock still impaled in her throbbing cunt, Susan was leaning to one side, her face buried in her brother's crotch. His huge cock was slipping over her tongue like a snake.

"Huh?" Gary said, awakening. "Susan?"

"Hello, little brother," Susan gurgled, looking up at his handsome face. "You mind if I suck this big dick of yours?"

"Fuck, no!" Gary said, wiping the sleep from his eyes. He propped himself up on his elbows and grinned. "Get after it!" be added, watching his cock disappear in her mouth.

Susan sank her lips around his thick hard prick, cupping his furry cum-filled balls. She rolled the hairy orbs around on her cheeks and moaned, able to feel the slight vibrations of his cum churning. When the thick brush of cockhair tickled her nose, she pursed her lips, then sucked back upward.

"You gonna give me a lot of cum?" she said, holding the base of his cock with both hands. She bit down lightly, squeezing his rubbery foreskin over the indention that separated his cockhead and the huge shaft. "Hmmmm? Enough to fill me up?"

"Mmmmmm… good!" Susan groaned, gobbling his prick back into her throat. She began sucking up and down furiously, feeling his shaft grow, pulsating to iron-like stiffness.

Gary nuzzled her between his thighs, wrapping his legs over her narrow shoulders. He humped upward, engulfing her head with his crotch, and leaned slightly to one side.

"Come on, dick sucker," he growled. "Lick it into your fucking, cum-sucking throat!"

And his prod blossomed to near pain, stretching her narrow throat open, Susan gave a gurgling moan, her spit slashing around his thick meat. She shook her head quickly, grinding her nose into this hairs, inhaling the heady, masculine aroma of his body.

"Baby baby…" Gary chanted, rolling over and pinning her beneath his body. He punched violently into her open mouth, digging his knees into her armpits, "That's so fuckin good! Suck it… suck!"

"Mmmmm…" Susan moaned. She could already taste the steam of his boiling cum, sending even more intense pangs of hunger to the back of her throat.

Gary grabbed the back of her head and leaned back, sitting on his haunches. He stayed like that for a couple of seconds, then stood, pulling her with him. As she knelt before him, he lunged forward, crushing her fully into his crotch.

"Eat it, you cunt!" he gasped, hammering into her mouth with brutal stabs. "Goddamn you, you fucking cum-sucking bitch, lick out my cream!"

Susan ran her fingers up and down his well muscled legs, then rested them on his ankles. As she continued licking and sucking his dick, she pressed her oozing cunt against his knee. An immediate throb of pleasure seared, constricted her pussy-walls.

"I need a cock in my pussy," she said, pulling her face away, trying to stand. "God, I feel like I'm on fire! I can't take it any move!"

"No you don't, cocksucker," Gary said, shoving her back down and jamming his cock back into her throat. "You're gonna stay right there and load up on my cum!"

Susan choked with desperation, her entire body racked with anguish. Her cunt was sucking on an imaginary prick, feeling horribly empty. She jammed her fingers into her cunt hole to relieve the ache, but it only made it worse. Again she pulled away.

"Please!" she begged. "I'm going crazy!"

Gary threw her to her back and straddled her shoulders, punching his cock deep into the back of her throat. When the base of his shaft jerked between her lips, he pressed his right foot between her thighs.

"I'll foot-fuck you if you want, but I'm not gonna let you stop blowing me," he said. He thrust his toes into her burning pussy-hole, feeling the slick juices of her body. "That OK?" he asked.

"Mmmmmm," Susan moaned, clamping her pussy-muscles around his toes, drawing him a little further inside. It wasn't a dick, but it would have to do for a while.

"Eat it, you cum-drinker," Gary murmured, leaning forward. "I'm getting so fucking close!"

"Shit!" Gary gasped. "Jesus… fucking Goddamned… UNH!"

The force of his climax was unbelievable for Susan. The rich creamy wads splattered like an explosion, sending streams of jism behind her nose, more into her cheeks.

She choked on his cum, feeling her own pleasure mount with lightning speed. She humped upward, constricting her cunt tightly around his foot, then gave a cry, this time from pure raw release.

"Oh yes!" Gary grunted, now shoving his full weight into her mouth. "Lick out every fucking drop and gargle it down!"

Susan sucked like she'd never sucked before, but even her hungry mouth couldn't drink fast enough. Twin jets of juice shot from the corners of her mouth, dribbling into her ears.

Soon her entire face was covered with a creamy film of cum, causing their bodies to smack together noisily.

"All of it!" Gary barked, shoving in the last of his load. He squirmed around over her face, then relaxed, crushing his pulsating cock fully into her throat. "Fuck, baby… fuck, yes!"

Susan's body began shaking violently as her pussy became as inflamed as her throat. Her cunt constricted, then began spasming around his toes, each rippling sensation growing hotter, more savage. She flinched wildly, her gurgling gasps of air mixing with his lava like cum as more thundering blasts of climax tore up and down her canal.

Gary fell to one side, but Susan moved with him, not wanting to take that delicious cock out of her mouth for even a second. She continued licking and sucking for a long while until he was totally dry, then pulled her mouth away. She scooped up the stray wads of cum from her neck and face, and sucked them between her lips. She held her head back, wallowing her tongue around, then let the liquid glide down her throat.

"Mmmmmmmm," she whispered, her voice greasy. "So good!" She went back to his cock and washed it with her cum-stained lips. "Think you can give me some more?" she asked.

"Sure," Gary answered. "But this time, I'm gonna ram it in your little pussy."

He pushed her to her belly and knelt behind her, gently lifting her ass with his hands. He kicked her legs apart with his knees and lunged forward, shoving his cockhead between her swollen cuntlips.

"Oh yes!" Susan cried out. "Fuck me hard with your big dick, you bull! Rant it in hard!"

Gary jerked forward, grunting loudly as his cockhead slid further into her pussy canal. When be reached full penetration, he held himself there a couple of seconds before withdrawing. When he did, he felt her muscles tighten, trying to suck him back in.

"Jesus, you're tight," he murmured, leaning forward, brushing his lips over her shoulders. "Just what I like… a nice tiny pussy to fuck."

Susan squirmed her ass around as she pumped backward to meet his inward thrusts. The hugging sensations inside her cunt were becoming almost too good, causing her to pant and gasp with painful ecstasy. She flinched, feeling the first electric jab of climax ripple up her cunt-tunnel.

"Harder!" she begged. "Ram it to me, bastard! Hard!"

Gary's pleasure was growing with equal intensity. Each time he buried his cock to the hilt, be felt his nuts throb. He dug his fingers into her soft flesh and pounded harder.

"Take it, cunt!" be growled. "Take every fucking inch and suck it up your dick-loving brains!"

Susan's orgasm peaked suddenly, clutching her insides like a grasping fist. But this sensation was only the first of many hard thundering waves of ecstasy to drill into her snatch. Soon she was a writhing mass of flesh, every cell in her body exploding with release.

"Give it to me!" she screamed. "Shove me full!"
