Marvin Cox: Seduced by sis

Amy Marshal held her boyfriend's cock with both hands, feeling the gigantic shaft throb. Slowly, she pulled back the loose foreskin which sheathed the gigantic knob and touched the glistening surface with the tip of her tongue.

"Oh, Keith," she whispered, nuzzling her face into the wiry crotch, "it's so big and… delicious!"

"Suck it, Amy," the boy said, placing both hands behind her head. "See you can lick it all the way in."

Although Amy knew that would be impossible, her hunger made her at least try. She opened her mouth as wide as possible and sank her lips down the rubbery slab of dick, feeling it pulsate even more violently, squeezing her lips painfully apart. When his cockhead reached her tonsils, her throat closed suddenly, gagging her. She took a deep breath and pulled back up, spitting the prick onto his stomach.

"I… I can't do it," she said, almost mournfully, eyeing the monstrous column of cock. "I'll choke to death."

"Just keep sucking," the boy said, pushing her face back down to his prick. "Unless you're ready for me to fuck out that little cherry of yours."

Amy shivered, almost forgetting why she had called Keith in the first place.

She had been talking with her best friend, Sherri, and the subject had, naturally, gotten around to boys – and this particular boy, Keith Rogers.

"Go ahead," Sherri had urged, her eyes glistening with anticipation. "Ask him to take you to the drive-in and do it. I bet he'd do it… so good!"

At first, Amy had balked. She felt this was the biggest decision she had ever had to make, and it frightened her. It wasn't just the pain she feared, but what might happen if her family ever found out, especially her brother. He was studying to be a minister, and had lately been watching her like a hawk, expressing unusual concern over her virtue.

And now, here she was, in the back seat with the best looking guy in school, holding his cock! Some virtue.

"Come on, suck it," Keith said, interrupting her thoughts. "Don't you want to?"

"Yes," Amy said, unable to lie. Just looking at the long, thick cock made her throat ache. But more, her insides were now growing buttery. Already her panties were sticking to her pussy, the silky material pasted in the puckered crack. "Yes," she said again, lifting the cock juice more to her lips.

"Oh… that's good," Keith said, raising his hips. Her mouth sank a little farther this time, taking in about half of his shaft. "Hey, no, keep it in," he said suddenly, feeling her suck back toward his cockhead. He applied more pressure to the back of her head. "Maybe… if you just… stay like that, you can… do it."

Although Amy felt her throat constrict even tighter than before, she did as he asked, holding her breath until she though her lungs would burst. A couple of seconds later, she gulped about an inch further down the huge shaft. Oddly enough, the back of her throat relaxed suddenly, accepting the thick ball almost eagerly. Surprised, she lunged forward, gobbling fully to the hairy root. As her chin jabbed between his cum-filled nuts, she twisted her face around, then pulled back quickly.

"Holy… fucking Jesus!" Keith grunted, half sitting. "You… did it! I… I don't believe it!"

Quite frankly, neither could Amy. As she looked at the enormous prick, she wondered exactly where she had put it. The thing was about as big as her arm.

"I did it," she murmured, not only proud of her accomplishment, but happy that the back of her throat was now begging for more. "And… and I'm going to do it again!" she said, locking her lips around the rock hard cockhead. "Mmm-hmmmmm!" she gurgled, again licking to the massive base.

"Oh… wow!" Keith grunted, feeling her lips tighten around the root of his cock. He closed his eyes and leaned his head against the car window. Every muscle in his body was now flexed so hard he was shaking. "Yes… just like that, baby," he whispered. "God… suck it all!"

Now that his prod had poked several times between her tonsils, Amy found it deliciously easy to take every inch. In fact, she wouldn't have minded at all if he was even bigger!

She dug her nails into the taut flesh of his thighs and began bobbing her head up and down with faster strokes, feeling her insides quiver each time she chewed into the patch of chocolate-brown hair. A few seconds later, she stopped, tasting a strange, acrid flavor. The steam from his cum-load was etching the back of her throat like acid, a sensation she couldn't explain.

"Are you…" she asked from the side of her mouth.

"Oh… fuck… not yet," Keith said quickly, his words barely audible through clenched teeth. "But… but will you take it in the mouth?"

I already have, Amy thought, confused. She looked through the brush of hair at the pained expression on his face. Then realizing what he meant, she nodded her head. He must be ready to climax. But she had only been doing this for a couple of minutes! Was it always this fast?

She began sucking more voraciously, her anger turned to raw hunger. What would it ate like, she wondered, when he did shoot his load. And would it come out like piss, in a steady stream.

"Get… ready, you little cocksucker," Keith whispered, rolling his body forward, almost into a ball. "God… I'm gonna blow that little dick loving throat of yours apart!"

When he began bumping up and down, punching his cock savagely in and out of her throat, Amy felt her insides tremble. Tiny explosions riddled the back of her cunt, then swept forward, burning around her puckered rim. She rubbed her knees together and choked suddenly as her orgasm burst wildly around her opening. The tiny lips of her pussy felt as if they were being yanked by an invisible hand. She flinched, stopping all movement for a second, then lunged forward with her face, slapping his stomach with her forehead.

"Unhhhh!" she cried out, her voice a hungry muffle. Then, as another powerful explosion tore up and down her cunt canal, she thought the top of her head would blow off.

"Oh… shit, you like it, don't you?" Keith said, his face contorted in anguish. "I'll just bet you love the fuck out of eating cock!" He thrust his hips upward savagely, drilling his meat deeply into her throat. "And… and I'll just bet you're gonna love it when I poke your little pussy apart too!"

"Mmmmmm!" Amy groaned, only vaguely aware of his words. The only thing that seemed to matter now was the fantastic way her pussy was rippling with release, the way her throat was engulfing his shaft.

Keith tried to hold back a little longer, but he knew it would be useless to fight the demands of his balls much longer. Already the swirling globs of cum were pressing into the base of his cock, squeezing into the constricted sphincter muscle.

"Suck… bitch, suck," he winced as a fine bead of sweat popped up on his upper lip and forehead. "God… suck me… good!"

Amy did exactly that, wondering when she would be rewarded with his orgasm. She scooped his nuts up with her hands and rolled them over her cheeks, giving them gentle squeezes. Suddenly, she felt his cockhead expand to what seemed twice its already huge size, then jerk, completely filling her throat.

"Now… you little virgin cocksucker!" Keith barked, exhaling. "I'm… I'm… oh… Jesus… fuck… now!"

At first, Amy didn't taste anything, just felt a fiery sensation sear her throat. But as more of his bubbly load spilled from the end of his shaft, it collected, boiling into her cheeks and under her tongue. Within a matter of a couple of seconds, he had shot so much cream into her mouth it was oozing from the corners of her lips.

"Are you going to fuck me now?" Amy asked quietly. "I… I mean… can you?"
