Best Friend Is My Son's Gym Teacher

Editor's note: this story contains scenes of incest or incest content.

*****

Note: I have gotten quite a few requests from fans for more sequels to my "My Best Friend and Our Sons" series, but for whatever reason I've lost interest in that one over time. However, I think this story is very likely to satisfy those who enjoyed that series. All characters in this story are 18 or older. This story involves father-son incest.

***

My name is Lucas, and I'm a 36-year-old single dad. My son, Liam, is an 18-year-old high school senior. His mom and I were young and unprepared when we had him. We quickly broke up, and I became his main guardian. She's not really in the picture anymore, but that's okay, because Liam has turned out to be the best part of my life. I absolutely love being his dad.

When Liam was 14, he came out to me as gay. This was not exactly a surprise to anybody who had met him. Liam has always been pretty...flamboyant. He's friends with a large circle of girls and he loves fashion. He has no interest in sports like football or basketball, but he does stay fit through dance and gymnastics. He was even the only boy to join the cheerleading team when he started high school. Of course, I don't have any problem with it, and when he came out to me, I just told him that I loved him and that I was proud of him for being honest about who he is.

Liam's always been spirited and independent-minded, but he's also always been a good student in school, and I've never really had to worry about him getting in serious trouble or anything. For a while, I was worried that he would get targeted for being a feminine gay boy, especially because he had no problem "strutting" around in an obviously gay manner, painting his fingernails, and dressing in provocatively tight, feminine clothes. But as he moved up through high school, he told me that he had figured out a way to keep boys from bullying him. I didn't know what he meant, but I was glad he had stood up for himself and solved his problems on his own like that.

So when I got a text from one of his teachers only a week into his senior year, I was surprised. It was even more surprising that it was his gym teacher, Chris Davis, because Chris and I had been best friends for years, and Liam knew him well and liked him. I couldn't believe Liam would ever get in trouble with him, but sure enough, here Chris was texting me and saying, "We need to talk about Liam's behavior in gym class."

I wondered what the problem could be, so I quickly gave Chris a call when he had an off period. "Hey, Chris, what's up? Is Liam okay?"

"Yeah, he's fine, nothing to worry about," Chris said. "I'm just a little worried about a couple things I'm seeing in class."

"Like what?" I asked. "You know him, he's never had any serious problems in school before."

"Yeah, I was surprised too, but I'm worried about his motivation," Chris said. "He doesn't seem to be putting forth his best effort."

I had to hold back a laugh. "I mean, no offense, Chris," I said as gently as I could, "but, ya know, it's gym class."

"I know, I know," Chris said. "And listen, I get it, it's kind of a blow-off class. And I know it's probably not Liam's favorite part of the day. But still..."

"What's he doing exactly?" I asked, starting to think Chris was being too tough on my son.

"Well...he comes out on the field like twenty minutes late," Chris said. "And when I ask him why, he'll make these jokes about how it took him a long time to change into his gym uniform. Which is obviously ridiculous."

"Hmm," I said, surprised at this. "That is disrespectful."

"Right," Chris said. "And I mean, a few minutes late? I'm not gonna make a big deal out of that. But he's missing almost half the class."

"Yeah, you're right, that's not okay," I agreed.

"And what makes it worse is," Chris continued, "it seems to be having an impact on some of the other boys in the class. The first time he was late, one other kid was also late with him. The next day, it was two. The past couple days, it's been like three or four boys each time. I really can't have that kind of negative influence spreading through the class."

"No, of course not, that makes sense," I said, realizing Chris wasn't just being a hard-ass.

"Especially when some of these other boys are the type who usually love gym class. The real athletic types, ya know? For some of them it's been the one class out of the day they actually look forward to," Chris said. "We both know Liam's a good student and he's gonna be just fine, but if some of these other boys think they can start blowing off school because Liam's setting a bad example, I'm really worried about where they'll end up in life, ya know?"

"Right, right," I agreed, shaking my head in disappointment that Liam was acting this way.

"So you'll talk to him?" Chris asked.

"Of course," I said. "As soon as he gets home from school."

"Great, thanks, man," Chris said. "Um...there is one other thing..."

"Sure. What is it?" I asked.

"Well...it's a little more...sensitive," he said ambiguously.

"What does that mean?"

I heard Chris sigh on the other end. "I don't want to make a big deal out of it," he said. "But if my principal comes and observes me, he's not exactly as easy-going as I am."

"Chris, dude, spit it out," I said, getting impatient.

"It's the way Liam wears his uniform," Chris said.

"Oh," I said, confused. "What do you mean? Don't all the kids wear the same uniform?"

"Yes, but..." Chris began. "Well, the uniform is a t-shirt and a pair of shorts. But, um, Liam will, like, roll up the sleeves and pull the bottom of the shirt up through the neckhole, so that it's almost like a crop top or something? And, uh, he also rolls up the waistband of his shorts so that they're hiked up, like, really high on him."

I rolled my eyes. I was used to Liam dressing somewhat revealingly, but I wanted him to feel free to dress how he wanted, especially since his fashion choices were an important part of how he expressed his sexuality. "I mean, it's Liam, he's trying to express himself, ya know?" I said to Chris. "I didn't realize you were so strict about stupid stuff like dress codes, man."

Chris laughed. "No, I get it, I'm not," he said. "But like I said, it could get me in trouble if I let him keep going this far with it."

"Seriously?" I asked, chafing at the idea of the school controlling my son's wardrobe choices.

"I mean, it's actually not an uncommon issue," Chris said. "It's just that it's usually the girls who do it."

"Right," I said, seeing an opportunity as I advocated for my son. "And are you just as strict with the girls?"

Chris paused, then said, "Okay, man, you've got a point there, I do let the girls get away with showing off some skin usually. But honestly, if a girl was showing off as much as Liam does, I'm pretty sure I'd have to step in and do something about it."

"Is it really so bad?" I asked.

Chris sighed and let out another laugh. "I know you too well, man. I expected you to be skeptical about this, so...I kind of gathered some evidence. Gimme a second. Check your texts and take a look for yourself."

I waited as Chris texted me a few pictures of Liam in his altered uniform. Sure enough, Liam had tied his t-shirt up into a little knot on his chest, so that most of his smooth, slim torso, especially his lightly toned abs, were on full display. I had to admit this was pretty extreme, and the way his cotton shorts were rolled up definitely took things too far. In a couple of the pics, Chris had zoomed in on the back of his shorts, showing that they clung tightly to him and revealed the bottom curves of his butt. Not only that, but it was clear he was wearing a jockstrap, because the straps were completely visible sticking out the legs of the shorts. I felt myself turning red in embarrassment thinking about my son strutting around like this at school.

"Um...yeah, ok," I stammered, having to laugh at the awkwardness of the situation. "I admit, this is inappropriate."

Chris laughed a little too. Then he said, with an odd kind of tension in his voice, "Yeah, um, to be honest, it's been kind of, uh, distracting having him out there on the field, running around like that."

I swallowed awkwardly, still staring at one of the close-ups of Liam's butt. "Uh, yeah...I would think so," I said.

"But, um, I do want him to feel like he can still...express himself. So I won't be super-strict and conservative about it. I just need him to, ya know, rein it in a little bit, so I don't get in trouble," Chris explained.

"Of course," I said. "I'll take care of it."

"Great. I knew you'd understand," Chris said. "Thanks, man."

"No problem," I said, and hung up.

I set down the phone, thinking about how I would address this with Liam. After a minute, I became aware that I had an erection straining against my jeans. I sighed in frustration. I felt ashamed and embarrassed about it, but this had been happening with disturbing frequency recently, as Liam had grown into a good-looking young man who liked to show off his body. I'd always been attracted to women, but I guess something about Liam being so feminine and pretty was sparking some unusual feelings in me. But of course, he was my son, so I quickly put it out of my mind and carried on with my day.

When Liam got home, I sat him down at the kitchen table and told him we needed to talk. First, I explained what Chris had told me about Liam showing up late to class.

"Oh, Daddy, it's no big deal," he said in a cute little voice, pouting. He usually called me "Dad", but when he wanted something from me or knew he was in trouble, he would adopt this baby-ish voice and call me "Daddy." He seemed to think that this would help him get his way.

"Liam," I said sternly. "It is a big deal. You're missing half the class, and it's disrespectful to Mr. Davis."

"You mean Chris?" Liam asked. Of course, Liam had grown up thinking of my best friend, who would regularly come over to hang out, as "Chris."

"I think we should call him Mr. Davis as long as he's your teacher," I said.

"Hmm, okay. I kind of like the sound of that anyway," Liam said with a mischievous little smile on his face, then added in his pouty little voice, "Is Mr. Davis mad at me?"

"Stop playing around, Liam," I said, irritated that my son seemed to think he could so easily manipulate me. "Mr. Davis is disappointed, and he's worried about the negative influence you're having on the other boys in the class. He said there are three or four other boys who are starting to follow your example."

"Yeah, well...I'm making friends with them, and gym class is boring," Liam said, an edge of defiance in his voice now.

I sighed, reminding myself that raising a teenager required patience and understanding. "And I'm happy for you to be making friends, but there's a time and a place for that. And just because you think it's boring doesn't mean you don't have to go," I said. "What are you even doing that whole time anyway?"

"I told Mr. Davis, it takes me a long time to change into my uniform," Liam said, but he had a sly little smirk on his face.

I rolled my eyes. "Nobody's buying that, Liam."

Liam laughed. "Okay, Daddy, I'm sorry," he said. "But really, the other boys know I don't like football and baseball and all that other dumb stuff we do in gym class, so they hang out with me in the locker room and help me avoid having to go out there the whole time."

"Look, I know you may not love gym class," I said. "But you can't be twenty minutes late every day. Mr. Davis will fail you, and I wouldn't blame him."

Liam scrunched his face up. "Fine," he said. "We'll try to be quicker."

"Thank you," I said. I recognized that this was not a commitment to come to the field on time, but I had learned by now to take what progress I could get and live to fight another day. Then I prepared to bring up the next subject, and I felt myself turning red. "Um...there's something else Mr. Davis is worried about, too."

"What is it?" Liam asked, rolling his eyes a little.

"The way you're altering your uniform," I said, ignoring his attitude as best I could.

Liam's face broke out into an amused smile. "Oh, he doesn't like it? I think it's super-cute."

"He thinks it's inappropriate, Liam, and he's right," I said.

"Oh, Daddy," Liam said. "You've always let me dress how I want, even when I was a kid, and now I'm an adult, so I have even more of a right to wear what I want!"

"I know," I said. "But you only just turned 18, and you're still in high school, so you still have to follow the rules."

"Seriously?" Liam asked, rolling his eyes again. "That uniform is so boring and ugly if I just wear it the regular way."

"Son," I said, trying to be reasonable. "We know you're expressing yourself, and neither of us wants to be super strict about this. But Mr. Davis said it's very distracting, and he could get in trouble with his principal if you don't...make some adjustments."

Liam raised his eyebrows. "Mr. Davis said it's distracting?"

"Well...yes," I said.

Liam smiled. "I mean...I'm not even showing that much skin."

"Son," I said flatly. "He...showed me pictures."

Liam's mouth opened in surprise. "Mr. Davis...took pictures of me in my uniform?"

I wondered if I shouldn't have said that. "I...uh...I mean..."

"Oh my god, show me!" Liam said, excited.

"I don't know, I don't think I should," I said, caught off guard.

"Oh, Daddy, come on, I just want to see how I look in them," Liam insisted, then quickly snatched my phone off the table. I wasn't about to get into a tug of war with my son over my phone, so I just sat there as he opened it and pulled up the pictures. "Oh my..." Liam said, then looked up at me. "I look hot in these, don't you think?"

"Son..." I said awkwardly, feeling myself blushing.

Liam laughed. "Sorry, Daddy," he said, then looked back at my phone, continuing to scroll through the pictures Chris had sent. "Wow, Mr. Davis really zoomed in close on my butt in a couple of these, huh?"

"I mean...he was just taking them for evidence," I said defensively.

"Mmhmm," Liam said slyly, then looked up at me again. "He really said I was distracting him?"

"Liam, come on," I said evasively. "Look at how you're dressed in those pictures. Of course it's distracting."

Liam bit his lower lip. "Would you be distracted, Daddy?"

I felt myself blushing. This was also something that had developed recently, as Liam had gotten older. It almost felt like he was flirting with me sometimes, but I quickly dismissed that idea and tried to shrug it off as just an aspect of his playful, open personality. "Anybody would be distracted by that outfit," I said finally.

He smiled, seeming to take this as a compliment.

"Look," I said, taking my phone from him and trying to get things back on track. "The point is, you need to scale it back or Mr. Davis could get in trouble. Is that understood?"

"Yes, Daddy," Liam said. "I'll be a good boy, I promise."

The next week, I gave Chris a call to check in on how Liam was doing.

"Hey, man, thanks for calling, I've been meaning to reach out," he said when he answered.

"So...how's Liam doing?" I asked. "Any improvement?"

"Yeah, a little," Chris said. "He's still showing up late, but it's been more like 10 minutes instead of 20, so that's progress."

I sighed in frustration, though I wasn't surprised. "Still, he should be coming on time."

"Yeah, but it's a step in the right direction," Chris said.

"How about his, um, uniform?" I asked awkwardly.

"Well, there's progress there too," Chris said. "All he's doing with the shirt now is rolling up the sleeves, so he's definitely showing off a lot less skin. He is still rolling his shorts up, but not quite as high."

"Okay...well, that sounds better," I said.

"Yeah, it is," Chris said.

"So...you're satisfied with how he looks now?" I asked.

"Well...the shorts are still pretty revealing," he said.

I sighed.

"Do you...want to see?" Chris asked, that odd tension returning to his voice. "You could, um, let me know what you think?"

I paused. "You took more pictures?"

"Uh, yeah, you know...I thought you might want to...take a look," Chris said. "Just so you can, like, give me your opinion, ya know?"

"Oh," I said. "Well...sure, send them over, I guess."

I waited a few seconds, then received several more pictures that Chris had taken of Liam in his gym uniform. One of them was a wider shot, but the rest were all zoomed in on his butt. As I began scrolling through them, I saw that his shorts still clung to him pretty snugly, but they now just barely covered up the bottom curves of his butt.

"Well, um...at least you can't see his, ya know, jock strap anymore," I said, feeling a little uncomfortable talking to my best friend about this as we closely examined pictures of my son's butt.

"Um, well, keep scrolling down," Chris said.

I continued scrolling through the pictures, then came upon a couple in which Liam was bent over. He must have been picking something up, but I couldn't really tell since the camera was again zoomed in so closely on his butt. When he bent over like that, his jock strap was slightly visible under the legs of his shorts. Again, I felt a pesky erection popping up in my jeans.

"Hmm, yeah, you can see his jockstrap in a couple of these, I guess," I said.

"Yeah...when he's bent over," Chris said. I couldn't be sure, but it sounded like he was breathing a little more heavily now.

"Hmm, okay," I said, still uncomfortable but also undeniably turned on. "You, uh, took a lot of pictures of him, huh?"

Chris laughed awkwardly a little bit. "Um...yeah, I guess," he said. "I just, uh, wanted you to see how he's dressing now."

"Right..." I said.

"So...what do you think?"

"Well, you're right, the shorts are still pretty revealing," I said. "But...I dunno. I don't want to be, like, too puritanical about it, ya know?"

"Yeah, right, I'm glad you said that, that's what I was thinking," Chris agreed. "Personally, I don't really mind if he walks around like this. And I don't want him to think I'm being too hard on him."

"Sure...that makes sense," I said. "You did say you let the girls show some skin, right?"

"That's true," Chris said. "So I guess it makes sense to let your son, uh, show off a little bit too."

"Yeah," I said, swallowing nervously. There was an unmistakable tension to the conversation now. "He's not gonna be too...distracting?" I asked.

Chris hesitated. "Well...I mean, he definitely likes to...strut around. And I do catch some of the boys...ya know...checking him out."

"You do?" I asked.

"For sure," Chris said. "I mean...I can't really blame them, ya know?"

I forced myself to laugh a little. "I, uh, didn't know you swung that way, Chris."

He laughed too, but it also sounded forced. "I mean, I usually don't, but..." Then he stopped himself, seeming to realize he was about to cross a line.

My erection was really throbbing now, but I too realized it was time to wrap this conversation up. "Okay, so, um...it's okay with me if you let him keep dressing like that," I said.

"Uh, yeah, okay, cool," Chris said.

"Okay...I gotta go," I said.

"Yeah, me too," he said. We both hung up.

After sitting there for a minute, trying to ignore my hard-on, I slowly picked my phone back up and looked again at the pics of my son bent over, his jockstrap sticking out the legs of his shorts. My hand drifted to my crotch. It's okay, just pretend it's some random butt, I thought to myself as I slid my hand into my jeans.

***

Later that afternoon, I felt ashamed that I had jerked off to pictures of my own son, but now that I had, it was difficult not to look at Liam differently when he got home from school. He had quickly changed into a pair of cotton pajama shorts, the type that college girls like to wear. For a few years now, these had been his favorite thing to wear when he lazed around the house. I can't say I'd never snuck glances at his butt in those shorts before, but now I found myself staring at him and getting stiff as he lay on his stomach playing video games in front of the TV. I forced myself to pick up my computer and try to get some work done before he caught me staring.
