Marvin Cox: The naughtiest sister

At the moment her climax peaked, Mike felt his nuts swell and begin to pulsate. The volcanic-like globs of jism were shooting from his prick. A hard, almost violent jerk ballooned his cockhead painfully. Then his guts seemed to empty inside her.

"Whore!" he spat, poking wildly into her slit.

"Cunt! Bitch! Unh! Whore! Take… take… Unhhhhh!"

Susan experienced another blast of hot release when his scalding juices flooded her pussy. And when the pulsating wads kept coming her moaning took on a tortured quality. For several long moments she was in a state of pure euphoria, writhing about as his jism sloshed back and forth inside her cunt-tunnel. But when he jammed in the last of his massive climax, the pleasure turned to agony.

Mike stopped moving suddenly, his body collapsing. He fell forward, crushing his sister beneath his hulking frame, his teeth sinking gently into the bock ether neck. His breathing was hot and wet, softly laced with grunts.

"Jesus, God," he said finally, "I think I fucked my nuts into you."

"Mmmmm, I wish you would," Susan replied. "I'd like to have all of you inside me."

They lay there for perhaps fifteen or twenty minutes, hardly moving, their bodies recharging. Mike pulled away and lay on his back, his fingers still on her tits.

"You said something about letting me fuck your little shitter," he said. "You still game?"

"Just promise to go slow," Susan said wit a grin. "I don't want you to rip my asshole apart like you did my pussy. God, I feel like hamburger down there."

"Well, since I've never done it," Mike said, "why don't you just take over?"

That idea suited Susan just fine. She looked down at his ramrod-hard cock, knowing if he shoved it in with the same force he had fucked her cunt, she'd be in big trouble. She straddled his waist, her head toward his feet, and carefully sat down on his belly. His greasy prick now lay in the crack of her ass, the head of it pulsating at the small of her back. She reached under and grasped his shaft, slowly jacking the foreskin over the meaty cockhead.

"Shit, I just hope I can do it," she said, aiming the end of his dick toward her tiny puckered shitter.

"Just take your time," Mike said, rubbing his fingers over her back and thighs, "We've got all the time in the world."

Not only was she hungrily lapping his toes and feet, she was also massaging his balls while she pumped her ass up and down. He seemed to be engulfed in a hot feminine blanket, or a greasy vacuum, pulling his insides out through his cock.

"Ahhhh…" he whispered softly, feeling his cum filling his balls. He gave another moan, wandering how long he would be able to take this torture.

Susan released his foot and sat up fully, throwing her head back. She ran her fingers up from her cunt to her tits, feeling the pressure of his cock force her guts upward. She squirmed around for a few seconds, then lowered her hand back to her pussy. The moment her fingers glided across her swollen pulsating clit, she winced with pleasure.

"God, I love this!" she said. "I love having a big cock in my ass! I just wish I could have one in my pussy at the same time!" Then, going with her fantasies, she continued, "And a great big juicy one to suck on!"

"Well, you do have three brothers," Mike said. "And when the others find out just how good our sister is, you'll get your three cocks."

Susan honestly hadn't even thought of that. She had just seen Mike there and one thing had led to the next. She certainly hadn't planned on this. But there were Brian and Gary – it was indeed something to think about. But right now, she had exactly what she wanted.

"Cock!" she said, expressing her thoughts. "Big hot, delicious cock! Fuck me, little brother! God, ram your cock in and bang my shitter like a drum!"

"I… I… baby! Fuck! Take… fuck!" When the boiling masses of juice slapped into the back of Susan's shitter, she gave a long, silent scream of release. The thundering spasms that shot up and down her cunt walls seemed to blast outward, drilling into her ass canal. For a few beautiful moments her entire insides were filled with hot, sucking jerks, making her writhe and buck like a tortured animal.

"Yes! Aieeeeeeee!" she screamed, her orgasm peaking. She thrust his balls into the crack of her pussy and felt the throbbing globs of cum shoot upward, through the center of his shaft and into her asshole. Again she gave a cry of agonized release, her voice cracking with emotion.

Mike hammered into her asshole for several moments, long after he had stopped splattering her insides with his jism. Then, giving her one last hard lunge, he crushed their bodies together, molding his cock to her asshole.

"Wow!" he gasped, collapsing, heaving for air. "I… shit… that was… good!" Susan lay there beneath him for a long while before even trying to move. She felt perfectly happy, engulfed by his strong muscular frame, his prick inside her hole, his breath on her back. Finally she pulled put from under him and pushed him to his back. She nestled herself between his thighs and lowered her face to his shit-stained cock and darted her tongue out, lapping down a thick glob of cum that hung from just under his cockhead.

"Delicious!" she exclaimed, rolling the liquid over her tongue. She pushed it back forward, squeezing it between her teeth. Then, washing it around with her spit, she let it seep slowly into the link of in throat. "Mmmmmm, I want more," he asked, clearly amazed.

"Just wait and see," Susan said, gobbling his long shaft into her mouth.

"Jesus, I see," Mike whispered passionately. "But I don't know how long I can wait!"

Susan peered through the window and saw Brian coming up the steps, his shirt thrown casually over one shoulder. He was dripping with sweat, which matted the luxurious growth of hair that covered his sculptured chest. From his cut-offs he sported a nicely muscled pair of hairy legs.

"Finished mowing the lawn?" she asked when he came through the door.

"Yeah," he said in a booming baritone voice, "and it's hotter than a motherfucker out there."

Brian watched as she sank her lips around his growing shaft and pulled it into her mouth. As she inched forward, taking more of it into her throat, she felt his cock jerk to life. When it was fully hard, she pulled back once more, just keeping his cockhead between her lips.

"You can," he said. "I mean… that is… suck me. But don't you want me to shower first?"

"No," Susan said. "I like it just like this." She pulled his shorts down to his ankles and gripped his huge thighs. Then, lunging forward, she took the entire length of his cock into her mouth. She sucked it in and out for several seconds and then let it flop from her lips, standing at an angle from his crotch. "Lie down on the floor and I'll wash you all over with my mouth," she instructed.

Brian kicked his shorts off and slipped off his tennis shoes then lay down on the carpeted floor. He spread his legs wide and pulled his sister between his thighs.

"OK," he whispered, looking into her face intently, "I'm ready when you are." When he felt her mouth once more clamp down on his prick, he arched his back and grunted loudly. "God, you wouldn't believe how much I've dreamed about this happening," he said. "I used to lie in my room and jack off thinking about you… when I was a kid."

"Really?" Susan said. "If I'd known that, I would have come in and jacked you off."

She nuzzled her mouth under his balls and spread his asscheeks slightly, revealing his dark hairy shitter entrance. She thrust the tip of her tongue against the rim, spewing in a bit of spit.

Brian humped forward, digging her knees into her armpits, and at the same time leaned forward, brushing his belly over her forehead. He placed his hands under her head and jerked her face harder into his crotch.
