Chapter 12
The last day of their summer vacation had arrived.
Susan and Matt looked at each other wistfully remembering all the good things that the summer had brought. Susan touched Matt's hand lightly then lowered her face, kissing it lightly.
"Remember the first time?" she asked.
Matt pulled her close, pressing his lips against the hollow of her throat.
"Would you care for a repeat performance?" he asked quietly.
"We have a couple of hours before Aunt Dora and Uncle Zeb get back."
Susan lowered her hands and touched the throbbing growth of his crotch.
"You mean you want to fuck your little sister?" she asked playfully.
"You're not going to believe this, Susan," Matt said, "but even when I'm fucking someone else, I'm still fucking you. That's how much you mean to me!" His words caused a wave of pleasure to ripple inside her pussy.
"Let's go to bed," she whispered.
A sense of urgency swept over them. They removed their clothes hastily, almost running to the bedroom. They stood by the bed, rubbing their bodies together, their mouths crushing against each other.
"Can I have you?" Susan asked into his mouth.
"Any way I want?"
"Yes," Matt answered. "I'm yours."
Susan pushed him down on the bed and knelt between his legs, her hands on his bobbing prick.
"I love your dick!" she whispered, running her tongue up the underside of his shaft.
"I want it in my throat! Will you fuck my mouth?"
"Yes!" Matt said, hunger in his voice. Susan pulled his dick into her mouth, sinking her lips wetly toward the base. She paused momentarily, enjoying the throbbing sensation against her tonsils, and then pulled upward.
Matt grunted as her eager mouth engulfed his meat. Hs thrust his hips upward as her lips sucked downward, burying his cockhead fully into her throat.
"That's good, you little cocksucker!" he said, pressing the back of her head with both hands. "Take it in and suck the piss out of me!"
Susan cupped his balls with both hands, rolling the hairy oval masses around on her chin. Shivers of delight ran up and down her spine. Matt threw his legs around her neck and pulled her head savagely between his thighs. He humped his body forward at the same time, ramming the full length of his dick into her lungs.
"Suck it, baby sister!" he groaned, almost sitting up, engulfing her head in his body. "Suck it like you've never sucked before!"
Susan locked her throat muscles around his pulsating cockhead, and gave a low growl. The soft, slippery texture of her hot tongue caressed and molded itself around his thick shaft like a snake. She could feel the base of his prick throb against her lower lip as his balls nuzzled against her chin.
"Ummmmm!" she moaned, the vibrations of her voice sending jolts of pleasure up the thick column of meat. Matt pressed his knees together and rolled over on his side, taking Susan with him.
"Suck it, you cum-drinking cocksucker!" he winced.
"Suck out my cum and gargle it down!"
Susan pushed her head back, slipping her lips up the full, round slab of meat.
"Fuck my mouth!" she whispered, opening her lips wide to speak.
Matt held the back of her head and raised himself to a kneeling position. He exerted pressure with his hands while he began slamming his prick in and out of her tight, hungry mouth. It seemed the harder and deeper he lunged, the move it made Susan eager.
"Goddamn, you sure love dick, don't you!" he said, stabbing his cock into the back of her throat. Susan grabbed his swinging nuts, squeezing and milking them with her fingertips, totally relaxing her throat muscles, she allowed Matt to plunge his prick in and out with increasing speed. Already she could feel the first rumblings of his boiling cum as his nuts vibrated against her chin.
"Oh, baby sister, I don't think I can hold back any longer!" Matt said, losing control of his body. His excitement began to inflame Susan. A deep, penetrating glow shot into the back of her cunt, sending jolts of pleasure up her spine.
"Drink it down, you fucking cocksucker!" Matt barked, his face paralyzed in a wince of release. Gargle my cum down and eat it!" Susan's body jolted with her own orgasm, a ripple of spasms that hit her just a couple of seconds before Matt began churning his first load of jism into her throat.
"Ummmmm!" she grunted, reaching under and thrusting her fingers inside her hot, dripping cunt. Matt crushed his body against her face, humping in and out of her mouth like a jackhammer. The first glob of sperm shot deeply into her throat, followed by a second, thick load. Susan was lost in an overwhelming sensation of lust. Her cunt was exploding with passion while her mouth was filling to overflowing with huge masses of milky fluid.
"Take it all!" Matt commanded, plowing the last few jerks of cum into her lungs.
"Drink every fucking drop!" Susan pushed him back down on his back, her hands under his thighs. She pulled his asscheeks apart with her fingers, digging into his dark, tight shitter. With a mouth full of hot, creamy jism, she pulled away from his prick and clamped her mouth around his asshole. She pushed the fluid out of her mouth and into the dark recesses of his shitter, washing the acrid tasting walls with her tongue.
Matt felt a warmth surge into his ass, as Susan forced the mouthful of sperm into his shit canal. He grunted as the liquid burned, squirting into his guts. Susan emptied her mouth entirely, then sucked the cum back between her lips with a smacking, hungry groan. When her mouth was full f sperm, flavored with his shit, she pushed it back into his shitter. Back and forth she spewed the liquid, and then drawing deeply, she drank it down.
Matt felt his balls boil once again with pleasure as Susan sucked passionately on his asshole. His prick began to throb and pulsate, slapping up and down against his stomach. He couldn't believe he was about to shoot off again so soon!
"You ready for some more?" he asked, jutting his hips upward.
"If you want it, I think I'm ready to go again!"
Susan quickly raised her head and grabbed his cock with both hands. But before she had time to place the end of his dick between her lips, Matt's cock exploded with a hot bath of creamy jism. Hot globs of sperm splattered against her fore-head, dripping down between her eyes. She watched fascinated at the spitting meat and began jacking it up and down with both hands. Matt watched as his prick emptied onto her face.
Large pools of sperm gushed all over her face, oozing down to her chin. He rolled over and rub bed his cock around on her cum-smeared face, fucking and thrusting his prick savagely against her eyes, her cheeks, and plowing into her hair.
Susan eagerly lapped down the thick juices, her lips and teeth chewing and biting on the throbbing underside of his shaft. She grabbed the base of his cock, and opening her mouth wide, guided the thick meat into her throat to capture the last delicious wad of jism, After a few seconds, Matt lay on his back. He stroked his sister's hair while she began a thorough lick job, gobbling down the stray streams of cum that had collected on his balls and thighs. She rubbed her face, scooping up thick wads of cum and drank them down, her lips smacking passionately.
"God, that was great!" Matt said, exhausted.
"What did I ever do to deserve such a wonderful cock sucking sister like you?"
For a brief second, Susan frowned, sorry that the summer was about to end. She and Matt would never have such liberties at home like they had had with Aunt Dora.
"You know, we haven't really expressed our appreciation to Aunt Dora and Uncle Zeb for such a great summer vacation," she said, sitting up.
"Well, we've got all night," Matt said. "Think there's enough time to do it?"
"If there isn't, we'll make time!" Susan said. It was then they heard their aunt call out from the living room.
"We're in here, Aunt Dora!" Susan shouted.
"Come on in and bring Uncle Zeb. We want to say goodbye!"
