Billy rode in the back seat of his daddy's car. They were on the way to Billy's Uncle Mark's house. Billy was excited because his daddy and uncle were going to fuck him and let him suck their cocks and swallow their cum. Billy and his daddy were going to spend the night there.

"Hey, guys," Mark said when he opened the door. Billy and his daddy, Roger, entered the house. Billy was totally excited because he was naked. He had ridden in the car naked, and his daddy had let him walk from there to the front door of Uncle Mark's house that way. Billy's little two inch erection poked out in front of him, quivering, as he stood in the front hallway with the adult men.

"Whoa, hey, Billy!" Mark said, noticing his nudity, "Look at you, all naked!" Billy grinned shyly, blushing. Mark rubbed Billy's blonde head and bent at the waist to kiss Billy's lips, sliding his tongue into the little boy's mouth while cupping his immature genitals with his hand. Billy moaned when he felt uncle Mark play with him and tickle his small ball sac with his fingertips.

"Hi, Uncle Mark," Billy breathed after the kiss broke and Mark stood up.

"Hey, Bro," Mark said to Roger, and Billy watched as the men exchanged a passionate French kiss. Mark put his arms around Roger's waist, and the older brother took Mark's face in his hands as his tongue explored the younger man's mouth.

"I notice you're still dressed," Roger said, and Mark stepped back.

"Sorry," he muttered, and pulled his t-shirt off over his head. Roger watched, waiting, as Mark pushed his shorts and underwear down and off, leaving himself as naked as his nephew.

"Better," Roger said, looking his younger brother up and down. Mark was a good three inches shorter than Roger's six foot one inch frame. His wavy hair was lighter and thicker, and he was generally thinner and smaller, though well toned.

"Stay naked 'til we leave, okay?" Roger said. It sounded like a question, but Billy could tell that it wasn't.

"Sure," Mark said, glancing at the floor, "No problem."

The younger brother slipped easily back into the submissive role he had always played when he and his brother had been kids. Roger had been the dominant sibling - physically and sexually - since Roger had made his younger brother suck him off as a boy. Mark had been 3. Roger had been 13. And though Mark hadn't done it voluntarily at first, he had grown to love sucking Roger's - and anyone else's - cock. He still loved it.

Roger stepped forward and took his naked brother in his arms, squeezing his bare ass and slipping his tongue back into Mark's mouth. Mark's cock swelled as his brother molested him.

It had been years since Roger and he had made love, and Mark fell right back into his role.

"Aren't you going to invite us in?" Roger muttered against Mark's lips.

"Sorry," Mark said, and walked to the living room, followed by Roger and Billy.

"Billy," Roger said, "Suck Uncle Mark's cock." Billy headed over to where his uncle sat, and took his cock in his hand, guiding it to his pink lips, standing between the man's legs.

Mark's head tipped back and he moaned as the boy sucked his hard cock.

Roger slipped out of his clothes and approached his son and brother. He took his brother's hair in his fingers and pulled Mark's head forward, toward his crotch. Mark's eyes opened, and he saw his brother's cock looming toward his face. He opened his mouth and took the long hard shaft between his lips for the first time in years.

Roger moaned at the familiar feeling of his younger brother's mouth on his cock. He pulled Mark's head back and forth, fucking his face. He jabbed his cock head at the back of Mark's throat insistently, and Mark opened his throat to take his brother's cock all the way down, until his lower lip pressed against Roger's balls.

"Ahhhhhh, yeah," Roger groaned, "That's it. Swallow my cock, Whore!" he said to his little brother. Mark moved his head back and forth, swallowing his older sibling's cock while Roger's son sucked his own hard rod.

Roger pulled Mark's head back, groaning as his cock slid slowly from the younger man's throat. He bent forward and kissed his brother's wet lips. He pulled back to whisper to Mark, a thin clear spit string connecting their lower lips.

"When's the last time I fucked you in the ass?" Roger asked.

"Oh, maybe five years go?" Mark replied, panting.

"Way too long," Roger replied, and kissed Mark again. Billy looked up at his father and uncle and watched their tongues swirling together between their open mouths. It looked really good to the little boy. He pumped his uncle's spitty cock in his little fist while he watched.

"I assume you've got lube?" Roger asked.

"Yeah," Mark replied.

"Well go get it," the older man said. He turned to Billy while Mark obeyed.

"Suck my balls while we wait for Uncle Mark, Big Guy," Roger said. He sat on the couch and spread his legs wide, with his ass on the edge, so Billy could bend down and put his lips to his father's scrotum.

Roger moaned and put his hand on the back of Billy's head, forcing the little boy's face against his balls. Billy's nose was pressed to his father's ball sac. He felt the egg-shaped orbs against his closed eyes. His daddy's curly pubic hair tickled his cheeks and nose as he lapped at the loose flesh of Roger's scrotum.

"Suck one!" Roger said, and Billy turned his head and opened his mouth to let one of the man's big balls slide into his mouth. Billy sucked gently, as Roger had instructed him, rubbing the delicate testicle with his tongue.

By the time Mark returned with the bottle of baby oil, both of Roger's balls were wet with his son's spit.

"Come on down here and suck my cock while your nephew sucks my balls," he told his brother.

Mark fell to his knees next to Billy and took Roger's hard cock in his hand. He sucked the long shaft into his mouth, forcing his face forward until he had swallowed the whole rod.

"Lick Uncle Mark's lips, Boy!" Roger gasped. He pinned Mark's head against his crotch while Billy ran his pink tongue along his uncle's lower lip, where it rested against his father's scrotum.

Roger let go of Mark's head and the younger man pulled away, gagging and drooling.

"Lick that up, Billy!" Roger said, and Billy lapped the slimy saliva from Roger's cock and balls. What didn't make it into his mouth coated his chin and cheeks.

"Bend over, Bitch," Roger told Mark. Mark turned and bent at the waist with his ass pointed at his brother.

"Man, when's the last time you shaved?" Roger asked. Mark had been required to shave off all his body hair when he had lived with Roger, but hadn't kept up the practice much the last few years.

"A few years, I guess," he muttered as Roger poured baby oil at the top of his ass crack. The cool liquid slid down the crack of his ass toward his anus.

"Well that's gotta change," he said.

"Billy," Roger told his son, "Come here and rub the oil into Uncle Mark's asshole." Mark moaned when Billy's thin, pointy finger pushed into his ass, carrying the oil with it. Mark's legs grew shaky as Roger instructed him to add another finger, then another.

"Sit on my cock, Slut," Roger said. Mark stepped back and reached between his legs for his brother's hard cock. He squatted, and rubbed the hot pole against his slick anus.

Roger held Mark's hips to guide him as he lowered himself onto his brother's cock. Roger moaned when the tight, slick orifice closed over his hot organ. Mark moved up and down, taking more of the cock in his ass with each downward thrust.

Both men groaned when their balls touched. Billy looked closely, enchanted by the sight of his daddy's cock disappearing inside his Uncle Mark's ass.

"Wow," he breathed. He couldn't wait until he was big enough to take his daddy's big cock all the way in his asshole.

"Suck my balls, Billy," he heard his father say from behind his uncle. Billy leaned forward and lapped at his father's scrotum while his uncle's cock and balls bumped his forehead whenever Mark slid downward.

Roger lifted up on Mark's waist, and the younger man slid off his cock, crouched over Billy's head. Roger's long cock fell forward and hit Billy's cheek, leaving a trail of oil on it.

"Suck it!" Roger demanded, and Billy took the oily shaft into his mouth.

It didn't taste very good, with the oil on it, but Billy did what his father told him, like he was supposed to.

Billy was a good boy, and his daddy said that good boys had to do whatever a man said to.

Roger slid three fingers into his brother's gaping ass while his five year old son sucked his cock. Mark moaned and moved his hips in a circular motion, pushing down against his brother's stiff fingers.

"Oh, fuck!" he groaned, "That feels so good! Fuck my ass with your fingers!"

Roger pushed Mark aside, until he lay over the arm of the couch with his ass pointed at his brother.

"Lie still, Bitch!" Roger hissed. He moved to kneel behind Mark on the couch, and Billy sat back to watch as his daddy lowered his face to Uncle Mark's ass and licked his asshole!

Billy was shocked and delighted to watch his daddy's tongue sink into his uncle's anus, digging around inside as he pulled on the man's cock from behind. He watched for a few minutes, until Roger saw him from the corner of his eye.

"You want a turn?" he asked, smiling wickedly.

Billy grinned and nodded, climbing up on the couch as Roger moved aside so he could take his father's place. Roger moved around to stand in front of Mark, who opened his mouth to suck his big brother's cock while Billy slowly lowered his face to Uncle Mark's ass. He extended his small pink tongue, tentatively touching the tip to his uncle's dark, wrinkled hole. He felt his father's saliva sliding on his tongue, and tasted a metallic tang.

Roger watched his son's face slowly nearing his brother's ass. Grinning, he pushed his cock deep into Mark's mouth while pushing back on his shoulders. Mark's ass moved toward Billy's face, and the five year old's tongue slid into his uncle's asshole.

Billy put his hands on Mark's ass cheeks and pulled back to look at his father, who was smiling down at him. Smiling back, Billy pressed his face to his uncle's ass, shoving his tongue deep inside the man's anus. He hadn't tasted much of anything when his tongue had slipped inside his uncle's ass just then, so he no longer feared it.

Roger leaned forward over his brother's back, driving his long cock into the man's throat while pressing his palms to Mark's ass cheeks, pulling them apart to watch as his son dug into Mark's anus with his small pink tongue.

The sight was incredible. Roger humped against Mark's face, bumping his nose with his abdomen with each short jab. He wanted to cum, but not yet.

Roger stood back, pulling his cock from his brother's mouth with agonizing slowness. Mark's eyes watered, and drool ran over his lower lip in a steady stream as his brother's hard cock was dragged across his uvula. He coughed and sputtered and spat when his mouth was clear of cock.

"Okay, Buddy," Roger addressed his son, whose tongue was still busily licking his uncle's asshole, "sit up so Uncle Mark can sit there."

Mark moved to a sitting position, panting to regain his breath.

"Climb up and sit on Uncle Mark's cock, Billy," Roger instructed, and Billy eagerly clambered into his uncle's lap, facing his father. The five year old reached between his pale thighs to grab Mark's hard cock and held it upward, aligned with his asshole.

"Here, let me," Roger offered. He gripped his brother's hard cock and aimed it at his son's anus so Billy could lower himself onto Mark's cock. Roger heard both Billy and Mark groan, in different octaves, and smiled.

Billy had a look of passion on his young face. He stared at his father, unseeing, and pressed himself down, taking four inches of hard cock in his ass before stopping.

"Good boy," Roger said. He kissed his son passionately. Bill whined into his father's mouth as Mark took his waist in his hands and started fucking him. Roger moved his hand to his brother's balls, and pulled on Mark's warm, soft scrotum. He pointed a finger at Mark's anus and tickled the slick, wrinkled hole as he fondled his balls.

Kneeling between his brother's thighs, Roger leaned over his son's head and kissed Mark, who sucked his tongue wetly.

"Gonna fuck your ass now, Baby," Roger whispered, and Mark nodded.

Roger took his cock in his hand and crouched down to line it up with his brother's asshole. He pushed upward, and felt Billy's naked body pressing against his belly as his cock sank slowly into his brother's anus.

Roger kissed Billy again as he fucked Mark. Mark used the momentum from his older brother's upward thrusts to drive his cock into Billy's ass. Billy whined when his father pulled on his hard little cock and kissed him.

When he kissed Mark again, Roger's chest pressed against Billy's face, and the boy kissed his daddy's nipples. Roger and Mar sucked each other's tongues with abandon, slipping right back into their sex roles as if they hadn't taken a five year break.

"Get ready, Baby," Roger panted to Billy, "Daddy's gonna cum, and I'm gonna cum in your mouth!"

"Okay Daddy!" Billy said breathlessly, while Mark rammed his cock into the little boy's ass from below.

Roger gave his brother's ass a few fierce jabs, then yanked his long, slimy cock from Mark's ass while grabbing Billy by the back of his neck and pulling him forward.

Bent at the waist, with his uncle's cock in his ass, Billy opened his mouth to suck his father's cock as it blasted sperm onto his tongue. Billy sucked hard at the familiar, beloved head of his daddy's cock, gulping down his sperm.

When he was finished, Roger helped Billy sit up, looking at his flushed, sweaty face. He smiled at his boy and leaned down to kiss him, licking his own cum from Billy's lips.

"How about it, kid?" Roger asked his brother as he jabbed his cock into Billy's ass, "Ready to cum yet?" Roger cupped Mark's sweaty balls in his hand and rolled them in his fingers.

"Oh, yeah!" Mark cried.

Roger pulled Billy off his uncle's cock and turned him to face Mark. Roger took his brother's cock in his hand and jerked it rapidly while Billy crouched in front of it, waiting.

"Open up, Buddy. Here it cums!" Roger said, and Mark cried out as his cock exploded. Three quick blasts of cum hit Billy's face, one after the other. White streaks lay on his nose and cheek, with one bisected by his mouth. Roger lowered the dripping cock to the boy's lips and let the last few pulses of sperm hit his tongue.

Billy smiled and swallowed, grinning up at his father and uncle proudly, with sperm glazing his lips and teeth.

"Great job, Big Guy," Roger said, and bent to kiss his son. Mark did the same, licking his cum off the boy's face.

"How about some Wii baseball until dinner, Billy?" Uncle Mark offered, and Billy nodded. Roger watched while the naked man and boy sat next to each other and played, thinking about what the evening would have in store......
