Uncle-Son and Nephew-Father

Author note:
I wrote the previous chapter, must’ve hit the anon button. Duoy

Mark only had one class left for the day since he had arranged his schedule to give him his last three periods free. All throughout English class he daydreamed about how Jason went gay for him, and the dildo he took in the phys ed office that was a perfect model of Mr. Stevenson’s dick. So much erotic shit had happened today just from not wanting to expose his real body to the other senior boys.

English class ended at noon. As a senior, Mark was allowed to leave when all he had left were free periods. He wasted no time starting to walk home in order to deal with the consequences of hijacking uncle Julian’s body.

Mark tried to quietly creep into the house to avoid drawing immediate attention to himself. The floor creaked under the weight of coach Stevenson’s body and ruined Marks plan.

Julian came right over to the living room to grill Mark. His head was atop Mark’s body, making him only five foot tall, and something else was different. Julian had completely shaved his beard and mustache, perhaps to match his new temporary body? The shave looked impossibly close, as if hair hadn’t been there before. The combination of his smooth angular face and small body made Julian himself pass for a high schooler. He didn’t smoke cigarettes and had kept great care of his skin after all.

“Okay big little dude,” said Julian taking in the sight of Mark’s new neck down, “now tell me why you took my body and what happened to it.”

At least his uncle was speaking calmly, thought Mark. He marveled at how Julian’s voice had been made higher pitch with his head atop Mark’s skinny little body. Mark hadn’t thought about it but his own voice was now deeper being on the coach’s large body. “I’m so sorry Julian, my gym class started the swimming unit today and I was embarrassed to have the other men in my class see me naked. I thought I could just borrow your body so that I wouldn’t have to worry for the first lesson.”

“Okay, I get ya. But where is my body now?” Asked Julian reasonably.

“Coach Stevenson confiscated it for a day for breaking his ‘no neckdown substitutions for the swimming unit’ rule,” Mark explained.

“Wow is that punishment allowed by the school??” Asked Julian surprised.

“No, not officially. He threatened to tell administration that I didn’t register my new neck down, which would’ve gotten me suspended,” said Mark sounding defeated.

“So basically we just have to wait until tomorrow to get my body back. Well I can think of worse bodies to be in. You know, this thing here really isn’t a bad dick, Mark. Yeah it’s not gonna win any awards for thickness, but a lot of guys would kill for this much length. Some guys are only as thick as you but shorter length. You should take some pride in your body,” said Julian, sort of feeling up the skinny body he was in. Mark was getting turned on seeing his uncle appreciate his former body, but he was in enough trouble already.

“Okay, here’s the plan. You’re going to pretend to be my dad for the day and do whatever I say. In exchange, I’ll cover for us with your parents and they’ll never have to know you did a head swap,” said Julian. It was a pretty generous offer considering Mark had lost Julian’s body.

“We can do that, and I think you’d pass for a high schooler but with my face I don’t know how old I could pass for,” said Mark.

“I have something for that,” said Julian. He rifled through one of hit suitcases and pulled out a spray bottle.

Since head-swapping had become a phenomenon, this world’s science had diverged slightly from that of the reader. Many products were geared towards making life on someone else’s body more convenient or comfortable. The product Julian had in his hands was one of those. ‘Ready Spray: Men’ would make a face instantly grow a full beard and mustache. It was popular among women who liked to wear men’s bodies. A lot of times, just taking off one’s makeup and growing thick facial hair was enough to let these women pass for men and experience life on the other side. For Mark, it should help make his already male face look older.

‘Ready spray: Women’ could also instantly strip your facial hair and give the appearance that it was never there. Mark realized that this must’ve been what Julian used to “shave” today.

Mark took the men ready spray and sprayed a little on his face while holding his breath. Like a miracle of modern science his face grew a full thick beard and mustache. Looking in the mirror he passed for a man in his early forties with a youthful but masculine face. It was weird seeing himself in the mirror and wanting the man he saw to fuck the shit outta him.

“Wow daddy, you look great. Don’t forget to get into character,” said Julian.

“You want me in character but what 18 year old boy calls his father ‘daddy’?” Teased Mark.

“Not only am I gonna call you daddy, you’re gonna call me ‘baby boy’. Now let’s go see if we can’t get you a pair of your dad’s underwear to use as a speedo, I wanna go to the beach. You should be about the same size as him with that neck down,” said Julian.

Mark was getting turned on by the way Julian was taking control, and putting them into the roles of father and son instead of nephew and uncle, respectively. He knew that his uncle was bisexual, but he didn’t think he was into kink, or into him. He tucked his growing erection into his right pant leg as it had snaked out of his briefs.

The two men went through the underwear drawer of Mark’s father. There were mostly just briefs of different colors, and lots of tighty whities.

“So which one would you like me to wear..baby boy?” Asked Mark. He felt like he was gonna get in trouble by calling his uncle something so saucy, but his uncle commanded it, and he’d promised to do as he was told.

“I’m not satisfied with these options. Go through your dad’s used hamper,” commanded Julian.

Mark went through his dad’s hamper, pretending it was the first time. The truth was, he’d been into his dad’s worn clothes at least a couple of times a week since hitting puberty. He found that smelling his dad’s junk via his underwear made his orgasms more intense. Obviously he’d never tell his straight and traditional father. There were the usual used briefs in the hamper and then a novelty pair of underwear caught his eye.

Holding them up, Mark examined the underwear. They were definitely an off white/cream colored thong, but there was less space for a package and there was a slot for the wearer to put their penis. At the end of that slot was a cute little mouse face with solid black eyes, a pink nose, whiskers and pointy ears. It was very gimmicky, but the thought of his dad putting his cock and balls into this made it quite a sexually intriguing item. Mark could tell that Julian was thinking the same thing.

Julian was Mark’s mother’s brother, so not related to to Mike’s father, Adrien. But honestly Mark couldn’t blame Julian for being attracted to Adrien even if they had been blood brothers.

Mark saw the devious look of intrigue blossoming on his uncle’s smooth face. “Please don’t make me,” said Mark as if reading Julian’s mind.

“I’m not gonna make you do anything. I’m gonna dress you, daddy,” said Julian, putting his hand out to receive the mouse thong.

Julian put his nose right into the penis slot of his brother-in-law’s novelty thong, inhaling the strong cock scent. Mark was secretly jealous but thought he’d probably have an opportunity to smell them the next time Adrien wore them.

Julian then started removing Mark’s clothing, starting with his polo. Mark complied by raising his large arms into the air. His shirt being off revealed his hairy beer belly and fat hairy pecs. Julian grabbed Marks big biceps, so Mark flexed them.

“Damn. This coach’s body has some serious muscle. And some serious jiggle,” said Julian, rubbing his nephew’s new belly, “When we’re out in public, ‘I’m thirsty’ is code for ‘let me suck your daddy nipples now’. I don’t care how many eyes are on us.”

“You’re the boss, son,” said Mark fluidly.

“Now you’re getting in the spirit of it dad,” said Julian.

Julian removed his ‘dad’s’ khakis and came face to face with Mr. Stevenson’s bulge in his underwear. He felt up Mark’s ass and crotch bulge in the bikini briefs before he felt it was time to shed those and dress him in his own dad’s underwear. He pulled the thong up, the string came up between Mark’s shapely and hairy ass cheeks and made it look like one big inviting pussy. The front side he loaded with daddy’s hearty cock and the pouch had just enough space for his large balls which had been churning with production.

“Damn dad, I could have all sorts of fun with you right here, but I think I wanna tease you some more. Let’s go to the beach,” said Julian, shedding his own clothing leaving his 18 year old body in nothing but a pair of size xs hanes tighty whities.

His package did look more impressive in those super small briefs he buys, Mark observed. He also liked the way his junk looked from a third person perspective. If/when he got his proper body back, Mark was gonna be prouder of it all around. Although being in this jiggling fifty year old man prison was a whole different kind of hot. It was like simultaneously being a young man and being every gay young man’s fantasy, a dilf.

Julian packed a beach bag and they headed out, texting Mark’s parents that they were going to swim and sunbathe. He had ‘daddy’ drive so he could be the carefree son. Being 18 again was awesome for Julian, especially a having a hot dad who had to do whatever his little heart desired.

The two men had the collective attention of everyone on the beach as they walked to find a spot. If wearing underwear as a bathing suit wasn’t enough of a statement, there was the fact that Mark’s underwear was a thong. Mark was so embarrassed, but the fact that his ‘son’ was putting him through this just for his enjoyment was turning Mark on. He started to enjoy the staring. Besides, what could anyone do? They were covering their privates by wearing underwear, so nobody could really say shit. Even though you could totally make out the shape of Mark’s thick penis through that sleeve.

Julian put up a beach umbrella and two towels for them to lay on. Julian laid down and said “Daddy, I need some sunblock on my back.”

“Sure thing baby boy,” Mark said, bending over and putting his sunblock covered hands on Julian’s back.

“Not like that, you have to lay on me while you do it,” complained Julian.

Suddenly Mark understood what his uncle wanted. He wanted to feel Mark’s thick cock on his ass in this public place. He put his knees down on either side of his ‘son’s’ hips and lined up his cock sleeve with his uncle’s perky little booty. He started to apply the lotion while rocking back and forth. No doubt Julian could feel it pressing into his backside.

Mark marveled at the fact that he was actually grinding on his own former booty. He liked having a son. Especially one that wanted his thick cock up his ass. People stared at them in disgust, thinking that a father in his forties was casually grinding on his son. Other dads on the beach were trying hard not to take peaks, but their efforts were clearly in vain. Some of them probably wanted to bend their own sons over to give them a good dicking.

When Julian’s back was done he told Mark to lay down and let him do his back. Mark complied and adjusted his boner as he laid down. Soon his felt his former package on his new ass. Julian was hard too, and pressing his borrowed cock into his nephew’s dilfy ass as he massaged the sunscreen in. It felt amazing to have such a small body and to press it against such a colossal one. He thought about how later if he wanted to, he could fuck Mark’s big hairy ass. Or maybe he wanted to try and take that thick five inch boner with his virgin boy hole. Decisions, decisions.

They had both been sunblocked and laying on their towels for a while. Even though they’d been drinking plenty of bottled water in the shade of their beach umbrella, Julian sat up and said, “Hey daddy, I’m thirsty.”

Mark’s cock stirred to life again at his uncle calling him ‘daddy’ loud enough for several families in the vicinity to hear. He knew what he was expected to do next. He knelt down facing towards his son, his beer belly pressing into Julian and he put one of his muscular pecs to his mouth. Julian began to suckle the hairy titty before him.

Mark’s nipples in his original body weren’t very responsive, so he normally just stimulated his ass and cock. This body, however, seemed to love having its nipples sucked. It was all he could do not to moan as his son sucked so hard it was like he was trying to get milk out of the damn thing. He ran his hands through Julian’s hair and found himself smelling his nice shampoo while he got his nipple serviced.

Mark could feel his uncle/son’s small hands roam his beefy body and settle on his extra large cheeks which were completely exposed, save for the thong string down the middle. Considering how much fat Mr. Stevenson’s body had, his ass wasn’t droopy with extra skin or anything, but quite perky and the perfect combo of muscle and fat. He probably did like a million squats to have this kind of build in his glutes, and they sure paid off.

By now some people were practically their audience. Julian bounced his dad’s cheeks with his hands for that audience. One young man seemed to be slyly humping his towel on the sand, trying to get off while watching them. Mark gave him a wink with his bearded face.

“Okay dad, I gotta pee, come to the bathroom with me,” said Julian, grabbing the beach bag so that their valuables would be safe.

Mark got up, his cock swaying. He had totally forgotten about his mouse thong attire. There was actually a bead of pre cum at the tip of the underwear but he did the walk of shame to the bathroom anyway.

Julian went to a urinal and seemed to be waiting for Mark to join him. When Mark got the idea and joined him, Julian said, “Stand at that urinal and hold me while I go.”

Mark stood at the urinal next to his son’s. He fished his own former penis out of his son’s briefs and pointed it at the urinal. It felt good in these bigger hands. Julian was right, Mark’s original dick might be a bit on the thin side, but it was still a proper handful, and even now Mark thought about putting it in his new ass. Mr. Stevenson’s hole was just loose enough that it probably could be penetrated by that dick.

The thought of his uncle’s face on his little frame hovering over him, fucking him in their current forms excited Mark. His thoughts were interrupted by someone taking the urinal to his other side. It was the young man who was mattress style masturbating on the beach watching them.

The young man was a redhead with with a good build of muscle and a little fat. He looked like a football player except a little less muscle. He stood 5’11” and was probably 160lbs. His butt made a nice shape in his loose fitting red bathing suit. His eyes were a pretty green and his freckled face had a smiley look about it.

The beautiful young man let the front of his bathing suit down enough so that his little two inch flaccid penis and ballsack flopped out. He looked right at Mark and said, “Me too,” angling his penis to Mark.

Julian hadn’t even started peeing yet due to not being used to having another man handle his equipment to pee. Mark reached out and grabbed the handsome man’s penis too. He closed his eyes for a moment to appreciate that he was holding two men’s penises. He opened them when he felt them start to pee.

Naturally, Mark had seen his own penis pee a million times, so he stared at the penis in his other hand and the man attached to it. The stranger’s penis was so little and cute. He couldn’t believe that this guy had the confidence to cruise, but he was glad he did. After all, even a little one like that would be fun to suck, or fun to watch bounce up and down as someone fucked him.

Just as the two men finished peeing and Mark had his hands back to himself, a beach patrol officer showed up in the men’s bathroom, and he looked intent on speaking with Mark. The redhead made himself scarce immediately, having already accomplished his goal of getting fondled by a stranger.

“We’ve been getting reports of a father and son acting inappropriately on the beach. Incest is illegal so we take these allegations very seriously,” said the 6ft tall officer. He was looking at Mark’s thong as if that alone were cause to incriminate.

“Well we’re not father and son, and we’re both of legal age, so unless you’re banning gay people from the beach then you have nothing to say to us,” said Julian, providing his and Marks IDs from the beach bag.

The officer looked at the IDs. They both had different last names due to Julian being his uncle on the mother’s side, and both men were at least 18. But the officer wasn’t satisfied, “I outta charge you with public indecency you punk.”

Mark could see that this homophobic douchebag was gonna get them in criminal trouble even though there were plenty of straight couples on the beach bordering on having sex. He didn’t want his life or his day ruined by this jerk, and before he could even think about what he was doing, *pow* he popped the officer’s head off with an uppercut. The officer would’ve still had control over his neckdown body, but he’d been knocked unconscious by Mark’s punch. Luckily Julian had the reflex to catch the head before it would land on the floor.

“Holy shit, nice one nephew,” said Julian, “but we gotta make a plan so that we don’t face any more crazy charges.”

“That’s daddy to you, baby boy. And I think I have a plan,” said Mark feeling confident.

The 30 something year old cops body was still standing up while his head was unconscious so just for fun Mark pulled down his pants and played with the man’s cock and balls, taking several pictures while waiting for someone to enact his plan. A boy of maybe ten or twelve entered the bathroom.

“Hey kid, ever wanted to be an adult? This cop said he’d do anything to be a kid again so I said I’d help him out,” said Mark.

“Hell yeah!” Said the kid.

Mark pulled the kid’s head off and plopped it onto the burly officer’s neck. He also put the sleeping officer’s head onto the boy’s body. The boy went running away happily in full uniform as fast as the officer’s out of shape legs could take him. From the beachbag Mark got a scrap of paper and a pen and wrote,

“Thanks for being a little dick, now you have one! xoxo”

Mark left the note on the officer’s new body, then turned to Julian and said, “Okay, that should buy us enough time to calmly get away.”

And they did. Mark and Julian collected their towels and beach umbrella, taking their time as to not arouse suspicion, got in Julian’s car and began driving home.

“Okay there have been a lot of hot moments today, but you punching that guy’s head off takes the cake. I wish I had gotten to play with his junk a bit before we put that kid’s head on his body though. Hey do you think he’s gonna remember our names from our IDs?” Asked Julian.

“Not a chance. He was so intent on getting us charged that he probably only looked at our ages real quick to see if he could get us on that. And by the time he deals with getting his body back from that kid he’ll probably remember even less. Personally I hope that that jerk can’t find the kid and has to go through puberty a second time, and that it’s less kind this time,” said Mark with a laugh.

“You’re right. Too bad we lost that ginger dude though,” said Julian.

“Yeah, but I’ve still got one hot guy to spend the night with,” said Mark, offering one of his large hands for his son to hold.

Julian took his hand and said, “I can’t wait daddy.”
