Marvin Cox - Seduced by sis

"God, baby, when Brad took you away the other night, I thought I'd go crazy," the boy whispered into her mouth. "All I could think of was this sweet pussy of yours."

"Well, now you've got it," Amy groaned, digging her nails into the rounded muscles of his ass. "Now fuck it! Fuck me hard!"

"First let me suck these tits of yours," Keith said, lowering his face to the two mounds of soft flesh. He took the nipples one at a time into his mouth, then squeezed his hands against her sides. As the two buzzing projections touched, he gobbled them both between his lips and bit down. "Mmmmm, baby, just… like I remember!" he whispered.

When Amy felt the sharp stab of his teeth, she bucked her hips upward. Her pussy lips were now pulsating around the underside of his cock, trying to pull him inside. She worked her ass around until the tip of his prick slid across the puckered crack.

"Suck me… while you fuck me," she begged. "God, I… I can't wait! My cunt feels like it's on fire!"

As she massaged the muscles of his ass, she looked at his body as if for the first time. He was exactly what any girl would want in a boy – a huge, hulking frame, plenty of chest hair, sculptured muscles, and a huge cock. And just thinking about that monstrous slab of dick caused her to tremble with anticipation. She was about to beg him again to ram it to her, when he locked his mouth around hers.

"Mmmmm, now," he grunted, lifting his hips, then shoving forward. The entire length of his shaft pierced into her pussy, forcing the constricted rim apart violently. "Oh… fuck… yes," he winced, his cockhead punching the warm pussy. "Like… this, baby?"

"Ohhhh… yesss!" Amy cried out. He was much bigger than she'd remembered, and although not quite as long as her brother's, his prick was slightly curved. "Fuck… me… hard!" she wailed, her passion building dramatically.

"Jesus… God, your little box is so… fucking tight," Keith whispered, kissing down to her chin.

"Mmmmmm," Amy said. "Somebody with a dick as big as yours." She looked into his eyes and grinned. "Why? You jealous?"

"Not really," the boy lied, "it's just that I wish it could have been me."

"But – you're fucking me now," she said. "Isn't that enough?"

"Yeah, I guess so," he said honestly. "But since you didn't wait on me, I'm gonna give it to you like no one else has."

"Oh… good," Amy said. "Just make sure it's… hard!"

The boy slipped from the bed, pulling her with him. He then stood up by the side of the bed and took a couple of steps backward until just her head rested on the sheets. He then yanked her legs apart with one brutal move and slammed forward at the same time.

"How's this, cunt?" he spat, looking down at her glistening tits jiggle from his assault. "You want… it hard, well, by fucking God, take it hard!"

Amy had almost no time to react to his savage punching cock. Pain and pleasure swept up and down her pussy canal. She threw her head back and bit the sheets, trying to muffle her desperate, agonized scream.

"Ohhhhh… God!" she shrieked, her eyes rolling back in her head. A massive, explosive release seared into her guts with such force, she thought her pussy would burst. "Yes! Jesus yes!" she wailed, grabbing at her tits so hard she thought she would yank them off. "Just… like… that, you bastard! Poke it to me! Tear me into a million pieces!"

"Goddamn… you fucking do want it bad," Keith said, amazed that she could take so much punishment. He accepted her pleasure almost as a challenge, now driving his prick in and out with unbelievable strength, his face contorted in what looked like pure rage. "Take it, you fucking slut!" he barked. "Take my Goddamned cock and eat it up to your brains!"

Amy's orgasm suddenly ripped into her cunt with the force of a punching fist. The back of her canal squeezed shut violently, then began fluttering around his shaft. The sensation burned forward, gripping his meat, then exploded around the thick, hairy root of his cock.

"Aaaqhhh!" she spluttered, now rocking back and forth, one hand tearing at her tits, the other stabbing between his plunging cock and her oozing cunt.

"Oh… fuck… me too!" Keith said suddenly, feeling his churning globs of cum spitting from his nuts. The swelling masses of juice spurted up the center of his shaft, then shot from the end of his ballooning prick. "Oh… Goddamn. I'm…"

Since Amy's convulsive orgasm had created a virtual vacuum in her cunt tube, the constrictions of her muscular wall yanked on his prick like a sucking throat. Then, as her pleasure peaked, his dick became trapped inside. In fact, her lips were fluttering so quickly, they lapped at the loose folds of skin around his balls.

"Oh… fucking shit!" Keith grunted, falling forward. He pounded his full weight into her spasming hole, thundering the bulk of his load deeply into the back of her cunt. "Fuck… it in," he gasped, chewing down on her shoulders, then sliding the tip of his tongue across her chest to her tits. He clamped his mouth around the mounds and bit into the soft, yielding flesh until he tasted the warm flavor of blood. "Fuck it, whore! Goddamn you, you cum-sucking slut, take my cock and fuck it up to your throat!"

"Unh! Unh! Unh!" Amy screamed, bucking beneath his plowing cock. Each quick stab sent harder ripples of pure ecstasy into her body, until her pleasure reached a level bordering pain. She finally gave a last scream of release, then fell back, totally exhausted.

"Don't stop, you little cocksucker," Keith growled, now slapping her around as if she were a rag doll. "Keep fucking me! That's… what you said… you wanted! Now… take it! Take it all!"

Amy wanted to move, bat it was impossible. She was so filled with satisfaction, it was even difficult to breathe. She could only lie there and be punched, enjoy the way his cock still pulsated with the last of his climax. And when he finally relaxed, crushing his entire weight into her cunt, it was almost a relief.

"Oh… wow," Keith gasped, his words wheezing from his mouth. "I… I feel like I just got my cherry popped. God, baby, if I'd have known you fucked like this, I would have been, in this hole a lot sooner than now."

They lay like that for several moments, afraid to break the spell each felt. It was as if their minds, as well as their bodies, were welded together. Finally, when Keith rolled over and lay on his back, he realized just how much he cared for Amy. He looked at her closed eyes and smiled.

"Sorry I went at you so hard," he said softly, touching the soft of her cheek. "It's just that I've teen wanting to do that for so long."

"I didn't think you even knew I existed," Amy said, the days at school when she saw him walk down the hall. "I… I almost didn't tell you," she added. "Sherri persuaded me."

"Sherri, huh?" he laughed. "I dated her once and didn't get to first base. That's why I was so shocked to see her in there with your brother." He suddenly frowned. "Hey, isn't your brother gonna be a preacher or something?" he asked.

"He's trying to be," Amy laughed, "but he's not getting much encouragement at home."

"He was really poking it to her, let me tell you that," Keith said, a sudden glint in his eye.

"Maybe you'd like to fuck her," Amy suggested. Before he could object, she added. "That's what I had in mind…"

"Huh?" the boy said, sitting upright. "You're gonna let me… I can, you don't mind if I fuck her?"

"Why should I?" Amy asked. "While you're fucking her, I'll be fucking Brad."

"Your brother?" Keith said, scandalized. He was silent for several seconds, looking at her intently. He them broke into a wide grin. "Well no small fucking wonder he's having a problem being a preacher."

"You don't hate me then?" Amy asked. "I mean, for… well, you know, making it with my brother?"
