Marvin Cox: The naughtiest sister

Susan Walker held her brother's cock with both hands, gently digging her fingertip under the loose foreskin. She looked up and gave his shocked expression a hungry smile.

"You don't like this?" she teased, pulling the swelling prick closer to her mouth. "Tell me you don't like it, and I'll stop."

Mike couldn't believe what was happening, let alone even comment on it. He watched her part her lips slowly and dart her tongue out, barely touching the tip of it to the underside of his shaft.

The sensation was electric, sending a jolt, of pleasure through his loins. He saw his hands move, as if pulled by a magnet, then rest on her shoulders. Her skin was as creamy and smooth as he knew it would be – yielding but firm.

"Want to play with my tits?" Susan asked, unbuttoning her blouse. "You do that while I suck you good, little brother."

"Jesus!" Mike whispered when he saw the huge melon-sized breasts flop forward. Her nipples were the color of coral, gently throbbing, perfectly shaped. He lowered his hands and cupped them, digging his thumbs into the delicate flesh. "Jesus!" he whispered again, spreading his legs a little wider.

"You like this?" Susan whispered, raising herself slightly. She sandwiched his cock and balls between her tits, rolling the mounds fully into his crotch. "Ever tit-fuck before?"

Mike shook his head, unable to speak. Already his nuts were throbbing painfully, ready to explode. Goddamn, he thought, I've never felt like this before! If she doesn't watch it, I'll cum right between her eyes!

"You want to cum in my mouth?" Susan asked, reading his tortured expression. "You want to poke a whole gallon in my throat? Mmmmmm, I love sucking cum!"

"Yes," Mike answered finally, his voice weak. "Suck me!"

Susan pulled his prick back into her mouth and gobbled down to the large, meaty base. As her nose rested in the thick wiry patch of hair, she began slapping her tongue all around his shaft. The delicious flavor of dried piss and sum assaulted the back of in throat with a salty pungency thirst increased hunger.

"Mmmmmm, and I'll just bet a boy like you has a whole lot of cum!"

"Come on, Sis," Mike said, now desperate for her to suck him. "Eat my cock! God, I can't take this… much longer!"

Susan placed her fingers at the base of his cock, pulling his shaft at a right angle to his crotch. Holding it firmly, she began bobbing her head back and forth, each stroke coming faster than the last until her face was a blur. Within seconds she felt his shaft begin to jerk even harder, and she could taste the steam from his nuts.

"Mmmmmmm," she moaned, probing her finger under his balls, gliding it into the crack of his ass.

"Goddammit! Suck, you cocksucker!" Mike groaned, crushing her face harder into his crotch with his hands, "Lick it good! I'm gonna blow your fucking throat away!"

Susan gave it everything she had, blowing him like he had the last cock on earth. While her hands was playing with his ass, swirling her fingers into the dark greasy hole, down his lean slender thighs, jamming them between his dangling nuts. She knew he was about to go crazy just from the way his rigid shaft was so tight, and her own body was reacting to what she was doing. Her pussy was oozing juices into her panties now, gluing the soft material to her crotch. She rubbed her legs together and felt a pang of ecstasy spear into the back of her cunt.

"Ahhhh!" she gasped, her voice a plea for his orgasm.

"Now!" Mike barked, jerking his hips forward brutally. "Goddamn, now… I'm… fuck! Suck! Unhhhh!"

The first searing blast of cum shot into the back of Susan's throat with smacking force. Then, almost immediately, another thick creamy glob splattered from his cockhead. His climax was so plentiful and quick, she didn't begin to have time to drink all he had to offer. The boiling juices sloshed around his plunging shaft and, finding no more room, dribbled from the corners of her mouth, wetting her chin. A few silvery strands fell onto her tits, causing another ripple of pleasure to spasm her pussy.

"AAARGGGG!" she choked, feeling her climax begin to build. The thundering jerks of ecstasy grew hotter, came quicker, then, exploded with violent release.

The sensation was so all-consuming and so brutal, her head flopped to one side, releasing his spewing cock. She watched it for a couple of seconds, feeling the greasy warmth as it spit on her neck and shoulders before she gobbled it back down. She gave another gurgling moan of pleasure.

"Take it ALL!" he grunted.

Susan sucked and pulled on his dick until she had taken every drop. And even when he was completely dry, she kept at it, working her lips up and down the shaft. When she felt him relax and pull back slightly, she scooped up the stray glob of juice from her tits, her shoulders and neck, and squeezed them between her lips, washing them around his cock.

"Damn, you really like that stuff, don't you?" Mike said as he watched his sister smack like a baby.

"I could drink bottles of it," Susan said, running her tongue over her teeth, pulling the residue of his orgasm into her throat.

She sat back on her haunches and studied him. God, he sure was some little stud. Although only a teenager, he had the body of a man – very muscular and angular. His square-jawed face was almost perfectly handsome, framed by a shock of blue-black curly hair. Another patch of dark hair haloed his prick, with just a hint of hair crawling up along his navel. She placed her hands on his thighs and kissed the tip of his dick.

"You gonna do it again?" Mike asked, swallowing hard. "I… I mean, would you?"

"When I'm finished with this big dick of yours, I'll let you know," Susan answered with a laugh. "And let me tell you, you little bull, it won't be for quite a while!"

She stood up suddenly and undressed, watching with amusement his expression. It was more than obvious from the way his prick was gently slapping his belly that he was getting excited again.

"You like my body?" she asked, knowing that he did. She was almost thirty, but she had taken care of herself, and anyway, she had all the natural endowments – firm large tits, shapely legs, a flat belly, shoulder-length red hair, and eyes as green as a fir tree.

"You're beautiful!" Mike said. "I never knew you were… so beautiful!"

"Come here," Susan whispered, standing with her legs spread apart. "Get to know my body."

Mike walked over and stood before her, his heart pounding in his throat. Slowly he reached out and touched the taut nipples that throbbed on the tips of her breasts. Then, leaning forward, he pulled them between his lips and bit gently. He felt Susan flinch, then her hands on his shoulders, working her fingers into his muscles.

"Lick me," she whispered, her head thrown back. "God, lick me all over!"

Mike washed and sucked her tits for a long while, until he could take the torture no longer. He knelt, licking downward, leaving a glistening trail of spit across her belly into her reddish-blonde patch of soft cunthair.

"Your pussy…" he said. "So… fucking little!"

"Eat me," Susan murmured, placing her hands on his wide shoulders. "Stick your tongue in and fuck me with it!" Mike had exactly that in mind, but first he just wanted to look at it, to smell the perfumed juices.

He placed his thumbs on either side of her tiny cunt-crack and gently pulled them apart. Her cunt was juicy and pink, almost like a steak, filmed with a slick coating of opaque fluid. Her small clit was nestled just at the top of the crack, partially bidden by the loose folds of skin, throbbing just like her nipples. He stuck his tongue out and touched it, making it swell.

"Ohhhh!" Susan whispered, feeling a stab of hot pleasure in the back of her cunt. She humped forward, trying to suck his tongue inside, but he moved back slightly. "Oh! I want it! God, Mike, eat me! My pussy is on fire!"
