Christmas at Uncle Brad’s

David was in a mood. Not a foul mood, or mad. But just incredibly, well, frustrated. And when he got like that he took it out on the weights. He normally needed his son Sam to spot him when he put this much on the shoulder press. But the 45-year-old was on fire, pumping out six solid reps before reracking the bar.

"Beast!" Sam exclaimed, that teen voice adopting the tone you'd expect a jock to give to one of his teammate buddies.

Maybe that's what he and his son were now, David thought with a deep worry as he rubbed out the soreness in his trap muscle. Buddies. He certainly did feel like a father lately, or at least not a good one. Fucking around with his own boy.

At first David rationalized it because Sam was so clearly up for it. The long, playful mutual JO sessions when it was just "guys' night." The way the young teen loved showing off his large dick. That first blowjob when David crossed a line he told himself he would never cross as he leaned over and tasted that beautiful penis, his son's dick for the first time. Making love to Sam's cock until he felt that insanely heavy young cum load flood his mouth. And, after looking up to see the huge surprised smile on Sam's cute face.

Then, not even two weeks after that, his still son asked David to teach him how to suck a dick. So David did, lovingly coach his own son in the finer art of giving head. And, when his Sam got him to the point of orgasm, far too quickly, David despite what his mind was telling him knew he wanted to cum in his son's mouth. So he did.

"Guess I'm fired up today," David replied to his son now with a shrug as he stood up from the press station in the Hewitt's oversized, tricked out home gym. The middle aged father wished he'd warn a T-shirt now, given the way Sam's eyes were sweeping up and down his hairy built torso. For such a sweet young man, Sam also had a bit of a hungry wolf in him, David realized.

He worried he was responsible for that, too. But Sam had been like that the last few weeks. Ever since Christmas at Brad's. Ever since he and Sam had taken turns fucking Brad's horny brother/uncle ass. Ever since he and Sam had shared their first kiss.

David had tried to put the breaks on it when they got back home. Bonding with Sam over football and lifting and watching NBA games. Trying to reassert his natural authority as a dad when he told Sam to limit his video game time. Anything but have sex with his son again.

Sam didn't say anything, but those eyes told David all he needed to know. His son wanted it, still. Wanted more sex with his father. He was respectful, patient, but it was like his teenage stud of a quarterback was waiting for when David was ready.

It didn't help that Sam was wearing only a pair of white compression shorts during the workout. It wasn't the first time he'd been attired like that - hell, the Hewitts were casual around the weight room - but with Sam's recent second growth spurt those shorts were basically a size or two too small and clung snugly and obscenely to every inch of Sam Hewitt's mid section. David could see every ridge of that soft, meaty teen cock and the ball sac pulled up and out from those sinewed thighs.

Worse, still, the white color almost faded in the pale creaminess of Sam's smooth muscle and for a second David could imagine his son standing naked in front of him. The very idea and vision made something happen that David had successfully resisted all evening. He popped a fierce boner in his own shorts.

He saw a hint of a smirk on Sam's face, as if he knew what was going on. But the young jock didn't saw anything. Instead he turned and walked over to the squat rack. This was their MO working out and had been since David started Sam on strength training at the age of 10 - gradually at first, to teach him the form more than anything, until Sam's hormones and natural development kicked in and he could lift for real. Father and son worked out different body areas so they wouldn't have to take off and put weights back on between sets.

Today was Sam Hewitt's leg day.

David watched as Sam put on two more ten-pound plates. Already this would be a personal best for him. But the father's mind wasn't on Sam's progress, at least not numerically. Instead, his eyes were riveted to that ass. Dimpled but getting a fuller, rounder development lately. He remembered watching those jock buns clench with each thrust as he fucked Brad. He remembered daring to explore between that crack with his own fatherly fingers, penetrating his own son while he was balls deep inside his brother.

Fuck.

That stretch-white material seemed thin, almost to the breaking point as it hugged that incredible teen ass.

"I'm going for four, Dad," Sam announced as he stepped up and ducked under the bar, spreading his legs to the proper stance. David had taught him the form well.

The ex-pro athlete was hard as nails in his shorts now as he said OK to his son and stepped up. Reaching out, he placed his hands on Sam's waist. Not tightly, just enough contact that he could assist if he needed to. And given the ambitious number of plates on the bar, he might need to.

That bare skin felt amazing to the father. He'd touched Sam almost in this very spot as the young stud fucked Brad. Sam's skin was so soft but getting that telltale male roughness, too. It was an indescribable combination. David's heart pounded in his throat.

Then Sam pushed off with his heels. He stepped back a half step, tightened his core, and David had to look in the squat rack mirror to watch the rippling of that perfect eight pack. He nervously worried Sam was catching him perving on him, but his son's gaze was pure focus, mentally preparing.

The first rep was wobbly, but Sam rallied. It wasn't pretty but he got his balance and stood upright, taking a deep breath before attempting a second go.

Number two was a lot better. Proper form, smooth range of motion. David could see the struggle in his son, and watch the trembling in his thighs. But at the top of the lift, even Sam's breathing was better, more controlled. He paused then went for number three.

This time, David's eyes were squarely on his son's rump. It was incredible to watch that muscle flex and stretch, then contract into a knotted melon roundness as Sam put all of the brunt of the exercise into his ass.

David had no idea how he was going to get through this workout, he was so excited right then.

Sam's pause was longer and the father's attention was brought up to examine Sam's face in the mirror. The third one had definitely taken it out of the athlete.

"You got another one in you?" the dad asked.

Sam seemed to reflect on the question. "Yeah, I'm good for it, Dad," he finally replied and then started the fourth,.

He wasn't good for it. David could tell immediately, once Sam hit the bottom of the squat and started struggling. The father's grip firmed on Sam's waist and he scooted forward to leverage this 6'2" frame back up.

"Fuck!" Sam hissed as the bar crashed onto the rack with a clang. Only then did David feel the nervous tension leave his son's body. "Sorry, Dad...."

David wasn't sure if his son was apologizing for cursing or for not finishing the set. David didn't care about either. His mind was on the soft, sweaty warmth of Sam's half-naked body in his hands. He couldn't help leaning into his son's back and feeling the quick contact with his bare chest as his palms traced him and down Sam's bare flank.

Just a quick feel, he thought, only he lacked the will power to step back. Particularly one Sam's poly-lycra clad ass backed into his hard crotch. David gulped and watched over Sam's shoulder, catching his son's gaze in the mirror. Gone was the frustration at not finishing the set, even as David pretended his mind was still on that.

"Great job, buddy," he said hoarsely. "Nothing like beating a personal best is there?"

Sam nodded, a dumb smile on his face as he tried to process a million emotions and a sea of testosterone pumping in his veins.

David knew he shouldn't be looking at his boy this way, but his eyes traveled down the reflection, taking in that young jock perfection. In a couple of years he'd be built even more, the product of a top-rated D-1 college program. But no need to rush that, David realized. Sam was perfect now.

The dad's eyes drifted lower. To those obscene shorts which were getting more obscene by the second. That teen shank was filling out, steadily, growing and firming. For all this time, ever since David first crossed those lines with Sam, he'd never actually watched his son get an erection.

He was watching it now, and it was the most beautiful thing in the world. His boy's cock growing hard, the soft spongy tool becoming a solid piece of wood and standing up to a proud staff in the compression shorts.

"I want you to fuck me, Dad."

The words shocked David to the core. He thought they were imagination at first, but as his gaze swept back up he saw Sam's expression. Serious. Needy. Horny. Sam had said that all right. The first time either of them had talked openly about sex since Christmas and it was his boy asking his dad to take his cherry.

"Son, I don't think..." the ex-pro said softly. But even as he tried to form a denial, his beefy mitts more openly explored Sam's exposed muscle, feeling more along the front and up the sides.

Sam's hardon was full now, a perfect match to the erection David didn't want to admit he had. "Dad, it's all I can think about," Sam said, his teen voice surprisingly husky. "I beat off all the time now, fantasizing about it...." Then daring to say it aloud, he repeated, "about you fucking me."

"God," David grunted. He was trying SO hard to be a good father. But, fuck, Sam was making it hard. "Fantasy is one thing, son," the man admonished. "Taking dick isn't so easy."

Sam gave a steel resolution in response. "That's why I want you to do it, Dad. I need a man who knows what he's doing." His breath was heavier now as he fought his out-of-control horniness at the realization his father hadn't actually said the word no. "A man who cares for me."

"Damnit, son," David hissed. But already his fingers were inside the waistband of those lewd shorts, teasing along the flesh just beneath.

"Not here," the father finally said, stepping back. It broke the contact but that didn't help, since he now had a clear view of Sam's nude back side and incredible ass, pumped and round from the squats. The man gulped as he continued, "your first time... it should be special.... Not here."

Sam nodded. He took in his father's words. Thought about them. Then he looked his dad in the eye and said. "I'll let you pick, Dad. You pick the time and place, OK? But I want it."

David gave in. He nodded. At that point he admitted he wanted this as much as Sam. Probably more.

"Promise?" Sam asked finally turning around, his erection pointing at his father. After the last few weeks, the athlete worried his dad would get cold feet.

"Promise," David said firmly.

Sam smiled broadly, feeling a victory. Part of him didn't want to settle for a blowjob or stroke session now, but he knew he'd have major blue balls without some release. Still, he had to let his father know. "Permission to speak man-to-man?"

David nodded. "Of course."

"Well," Sam started. "You decide what the right place is, Dad. But this room is special to me. I don't know... I guess I always associated it with you and with being a man and being invited into that world with you."

"Oh buddy...." David's heart pounded with emotion as well as horniness.

Sam continued. "And I don't think I ever told you this, Dad, but this is where I got my first erection. I remember that day clearly, I was hanging out, watching you work out, and I felt this unfamiliar feeling and right then I popped my first boner. Right here."

"Fuck, son," David growled.

"Of course, I've gotten a little bigger since then," Sam smirked as he nodded down to his taller, more developed naked body and large cock that somehow seemed even bigger to David at that moment.

The father couldn't take it any more. He pulled the waistband of his shorts and exercise briefs over his hardon and yanked them down.

Sam actually gasped when he saw it. He'd seen his father's hard cock many times now, but it somehow seemed bigger, angrier. Particularly when his dad's fist curled around it and give the erect paternal dick a few slow strokes.

"You sure about this, buddy?" David's voice was horny but concerned.

Sam looked up into his father's eyes. "Never been surer, sir," the jock answered sincerely. "When you shoved your fingers in me at Uncle Brad's, well, it felt really fucking good." The son was no longer worried about cursing now, and in fact relished the more grown up words given the situation.

David's face broke into a surprised smile. "Is that right, buddy?"

Sam just nodded, blushing at the admission.

David took the initiative now, kicking off his shorts and stepping up to his handsome son. The skin felt warmer now as the father's fingers latched on to it, pulling Sam's younger, less muscular frame toward his own ex-NFL body.

The kiss was even more intense the one he'd laid on his boy at Brad's. Achingly soft, even as their hard cocks pressed against one another. This was a surprising first for the two, as well. Son to father, dick to dick. Pressing, then playfully batting like swords.

Sam laughed. So did his dad.

"I love you, buddy," David said softly, reaching down to palm the bare ass cheeks, like he'd wanted to do for the last half hour. "So much."

"I know, Dad," Sam whispered back. "I love you, too."

Their kiss was harder now, full of tongue, David's driving between his son's lips, trying to taste and reach his son's very soul. And then Sam stepping up to return the dominance of the incest kiss.

David sighed in horny frustration as they broke for air finally. "Oh fuck... I don't have any lube."

Sam grinned, reaching down to grip his dad's boner. "I may have stashed some down here," the jock chuckled. "You know, just in case."

David smiled big and cupped the bottom of Sam's chin. Like he'd just made a Pop Warner play. "That's my boy," he laughed.

He watched, excited, as Sam walked over to shelf where they stashed belts, bands, and lifting accessories. Sam squatted down, letting his father see those round bare cheeks part, and reached in to root around toward the back of the bottom shelf. When he pulled his arm back, he held a tub of vaseline.

"This seemed to be Uncle Brad's favorite," Sam smiled, standing back up, as hard as ever. David felt a twinge of horny guilt as he admired just how smooth much of his Sam's body still was. "I have to admit it felt pretty good on my cock, too."

He tossed his dad the contained, and David caught it effortlessly, like the seasoned football veteran he was. "I bet," he chuckled. Then he nodded over to the bench they used for chest presses. "Lie down over there," he instructed.

Sam lay a towel on the bench and sat down before lying back. God, he was so beautiful, David thought with a deep sense of fatherly pride. He'd made that boy, raised him the best he could. But he couldn't take all the credit. It was Sam who was such a good kid. It was Sam who pushed himself here in the gym and was already starting to see results. It was Sam who wanted him.

David crouched down and nervously Sam worried his father was going to go down on him. At any other time he would have welcomed that, but he knew he wouldn't last twenty seconds with his dad blowing him.

"Come on," David urged, surprisingly impatient. "Lift 'em up son." His hands were under Sam's hamstrings to guide the legs up. Sam got the hint and did the rest of the work, raising them. It felt surprisingly lewd to lie back with his toes to the ceiling. Like Uncle Brad did.

Only David's hands guided the thighs further back, toward Sam's chest. And he leaned in, licked his lips, then placed his mouth at his son's hole.

This was new to Sam. He'd fucked his Dad three times now and Uncle Brad once and never had it occurred to him to lick a man's hole before. It had never even entered his fantasies.

It would now. His father's tongue felt incredible. Ticklish almost, but in the best way possible as it licked around the young jock's hairless pucker before darting playfully against Sam's entrance.

"Holy fuck!" Sam gasped. His body tensed in reaction, his hole tightening up. Then just as automatically, the pucker dilated for his father and in slipped a half inch or so of the man's tongue. THAT drove the teen wild. He humped excitedly against his father's face, and his whole body felt alive.

Just when Sam thought he couldn't take any more, David pulled back, his eyes intently on his son's spit-wet cherry. Reaching down he scooped up a big dollop of vaseline and smeared it on Sam's hole.

Sam expected a slower foreplay, but instead David's thick index figure bore right into him, right into the loosened entrance.

"Shit!" Sam let out. He watched a smile break out on his father's face as that finger stopped dead still. Then, it began again. In and out, not gentle but not hard.

David pulled out entirely. "Doing OK, son?" he checked in.

"Oh yeah," Sam replied. This was all unfamiliar, but the fact he'd been on the other end of the fuck made the process less intimidating somehow.

Even when David brought two fingers and pushed right in, spreading the sticky grease all along Sam's delicate virgin insides. The finger fuck was intense now, but good. Better than good. Incredible.

Then came his father's voice. "I'm pretty thick, you know," he observed before a third finger joined in. Sam's elastic hole stretched but the teen felt excited and ready.

If they'd had a clock, David would have been aware he'd been giving fifteen solid minutes of foreplay to his son. He leaned up and smeared some vaseline on his hard prick. He didn't need too much, his boy was good and lubed now. But this was Sam's first time.

He scooted forward and looked down on Sam. Young, studly, looking up with love and expectation. "So, this room is pretty special to ya, huh, son?" he asked.

Sam nodded. "You don't even know, Dad," the football jock replied. "When we're here, just us, it's like there's no one else in the world. Just you and me."

David smiled and lined up his cock. "You ready for me to make this place even more special for you?"

Sam nodded, eagerly. Desperately. "Please.... only...."

David paused, a little nervous. He'd been THIS close to just plowing into his boy. "What is it, buddy?"

Sam reached up and felt his father's firm, middle aged muscle. Hairy, hard, with just the right amount of give. He was going to get fucked by a man - the most amazing masculine man in the world. "Tell me you love me." Sam repeated with excitement. "Tell me you love me when you fuck me."

David's heart melted and his heart pounded. "I love you, kiddo. So much." And like that, David Hewitt's dick pressed past his only son's tight entrance.

Sam grunted in discomfort at the entry but he took it. David knew he would. He knew his big boy was ready to be a man, fully a man. So he pushed in harder, deeper. It touched something deep inside Sam and the dad had a good idea what.

"Fuck me!" Sam gasped. "Fuck me Dad."

David leered down as his hips pumped. "Not cherry anymore are ya, kiddo?"

"Fuck no," Sam replied through choked breaths. "You're breaking me in Dad. So good."

David's thrusts were steady, getting close to full penetration. It was wild how frickin tight Sam's ass was and yet how he was opening up for him.

"Harder!" Sam urged. "Go harder, Dad."

Something was hitting Sam's p-spot just right. His normally cocksure kid was slutting out on his daddy's cock, the first go out. Urged on, David started nailing his son's ass, forgetting his resolution to go easy on Sam.

It wasn't too hard, though. Sam grasped at his father's naked torso, clenching the daddy muscle before pulling his old man down for a kiss.

The two Hewitt men fucked like that. Kissing, clinging to one another, feeling the sheer physicality of Sam's first time.

The kid fired first, hands free. David could feel the warm semen shoot between their heaving bodies and smell the bleachy-musky sent of sperm in his nostrils. It sent him over the edge, cumming deep inside Sam's no-longer-virgin guts.

The fucking slowed rather than stopped immediately, as the dad rode it out, and Sam slowly regained consciousness after the intense, toe-curling orgasm. Even when David's paternal cock softened and slipped out, pulling a cascade of fresh cum out of Sam's abused hole with it. The men stayed embraced face to face, alternating soft kisses with deep gazes into each other's eyes.

"Is it always like that, Dad?" Sam asked finally. He had to let his legs down now that the cramping was setting in, and he had to watch in admiration as his father had his own cum matting down the hairs, with the sweat.

David winked. "Nothing's like your first, buddy," he said. "Though some things get even better."

"I can't wait," the teen replied. Then a fear gripped him. "Please tell me we're going to do this more, Dad."

David stood up and nodded. His dong fell heavy and swung between his hairy thick thighs. He'd never get sick of the look of admiration in Sam's eyes at at that moment as his kid watched every movement of his dad prick. "We're going to do this more. A lot more," David announced.

He reached down and helped Sam to his feet. The jock had that just-fucked weariness, like he had to stand on sea legs. "One condition, though," he said sternly.

"What?" Sam asked.

David patted his son's sweaty back and couldn't resist pulling the handsome naked young man into another embrace.

"I don't want sex getting in the way of your workouts," David said, half joking, half serious. "No fucking until we've put in the time, hear?"

Sam smiled, reaching down to cup his father's soft genitals. The cock and balls that had sired him. The tool that had taken his cherry. Even in their sated state, his dad was plumping up in his hand. "Wouldn't have it any other way, sir."
