Chapter 1

Tess pulled her mouth off her brother's pulsing cock.

"Mmmm, God," she grinned. "Is that good!"

"Just hurry up," Jeff panted. He clutched the back of her head and pressed it closer to his glistening prick. He swiveled his hips upward, trying to force his cock back into her mouth.

Tess swung her head to fling blonde hair out of her face.

"Just hold your horses!" she gasped. "I'm doing the best I can!"

She opened her mouth and wrapped her lips around the bulbous prickhead.

Jeff raised his hips still higher, eager to feel her mouth encircle his entire cockshaft. He pressed a little more firmly on the back of her head at the same time, feeling his aching cock sink farther into his sister's mouth.

"Mmmm, yeah!" he whispered. "That's it! Suck as much of my cock in your mouth as you can!"

He started to buck. His body quivered as he flexed his ass muscles.

Tess moaned and squealed as she felt his huge cockhead press into her throat.

"That's the stuff," Jeff said. "That feels so good! I'm ready to shoot any second! Pound my cock with your fist! Ooooo, yeah! You'll have my cum any second now!"

He worked his hips in circles, feeling her tongue press against the thick cum-chute on the underside of his cockshaft, throbbing and ready to blast a load of creamy jism into her throat.

Tess bobbed her head up and down his cock with increasing vigor. The thought of his cum splashing into her mouth excited her. Her pussy was already damp, the deep interior of her cunt itching as it trickled with excitement.

As she tightened her grip around her brother's cock with one hand, she reached into his crotch with the other. She clutched his balls. Her fingers encircled the upper part of his low- hanging sac and pulled downward. Then she fondled his meaty balls while her fingernails scraped over the tender flesh of his inner thigh.

She pulled more of his cock into her mouth. She worked her tongue around the long prickshaft. Every now and then she lowered her face as close to his crotch as she could, sniffing the heady aroma of manly cock-hairs, sweaty balls and his cock slick with her spit.

She bobbed lower. The knob of his cock fucked deeper into her throat. She gagged.

"Easy, Tess," Jeff said between rapid breaths. "Don't bite off more than you can chew. You're doing just fine the way it is. Just pound my cock harder. Apply more suction with your mouth." He rotated his hips downward, easing his prick out of her throat. "Aaah, that's it. You don't have to do that deep-throat stuff the first time. We can work up to that later. For now, just keep sucking my cock with your tight mouth. Mmmmmm, yeah!"

He rubbed the back of her head reassuringly, twining his fingers in her long, wavy blonde hair. His ass was bouncing with increasing fervor as he inched closer to shooting his wad in her mouth. Though his prick and balls were aching for release, he didn't want to choke her and ruin her first time at cock-sucking so she would never want to do it again.

Tess gripped his lower cockshaft tighter and pounded it all the harder. She knew it would be just like when he pounded his cock himself, and would probably cause his cum to shoot all the sooner. Her lips raced up and down his prickshaft, her tongue tickling the tender spot just under the giant cockhead and pressing more firmly against his prickshaft.

Soon Jeff's legs started to quiver. He arched his back and tried to shove more of his cock into her mouth. Then just as quickly, when he heard Tess gag again as his prickhead pressed into her throat, he sank his ass into the mattress. His body jerked uncontrollably as he felt the impending release of his cock and balls.

"Oh, yeah!" he gasped, squirming and panting.

His neck arched, his head pressing into the bed. He clutched his sister's head tightly and held it still. His crotch began slapping up into her face fervently, his cock stabbing into her mouth as it exploded.

"Unh, unh, unh!" he panted. "Oh, yes, yes, yes! This is it! I'm coming! Suck it, Tess! Suck my cock hard! Pound it, pound it, pound it!"

Tess bounced and jerked violently as she sucked as hard as she could on her brother's erupting cock. Her one hand massaged his balls with great speed and dexterity while the other raced up and down on his slick prickshaft. Her eyes bugged out as she felt his cock pulse in her mouth with every blast of his hot thick cum.

Jeff raised his head and stared through watery eyes at his crotch. He watched with great joy as his cock disappeared over and over again into his sister's mouth. His chest heaved frantically as he pumped a mighty load of his precious warm cum into her throat.

"Oh, god, yessss!" he wailed. "Suck it, Tess. Suck the cum right up from my toes!"

Tess's cheeks caved in from the pressure she was applying to his exploding cock. She could feel the mighty spurts of his cum shoot against the back wall of her throat as she pounded his cock frantically. She tried to swallow as fast as she could, welcoming with great glee the torrent of his salty, funky spunk.

When she felt the blasts of his cum slow a little, and the great fullness of his cock stuffed in her mouth shrink, she pulled her head back. His hands relaxed their pressure on her head and she was able to pull back far enough so only the head of his great cock was in her mouth. She sucked on his prick-knob as if on a giant soda straw, eager to vacuum up every drop of his tasty cum.

The great spurts of his cum slowed to a few sprays, then oozed out his cock in a thick, steady stream for a couple of seconds. She greeted the gobs of cum on her tongue eagerly, then rolled the rich cream around in her mouth, tasting the great male flavor. With hums of delight, she swallowed happily, sending the gooey fluid down to join the rest in her belly.

Jeff's body convulsed a few final times as his cock chucked up the last of its load. He let his ass fall back to the bed while his sister sucked and licked his flagging cock dry. He stroked her pale blonde hair gratefully, his chest heaving as he struggled for air.

Tess slurped her mouth off his prick, then sucked and kissed his cockhead a few more times. Her fingers continued to play with his balls, feeling the shriveled leathery sac grow long again after producing his mighty load. She scratched his thighs and balls and gave his cockhead a final sucking kiss as she laid his limp prick on his hairy belly.

Then she raised her head.

"How'd I do?"

"Great," Jeff said between breaths. "Absolutely great. That was one hell of a blow-job!"

"Thanks," she said, grinning. She tucked some loose strands of her bright-yellow hair behind her ear and started to get up to leave.

Jeff grabbed her wrist. "Hey, where are you going?"

She scowled at him. "Well, that's what you wanted, isn't it? Wasn't that our agreement?"

He gave her a lusty grin. "Well, yeah, but -"

"But what?"

"Don't you wanna get off, too? I mean, what were you playing with yourself for if you didn't want to get off?"
