My son Caiden will be turning 13 soon. I've seen him sporting more wood which isn't a surprise. His mom left a long time ago, and since it's just us guys in the house we aren't shy around each other. I remember how sensitive my dick was at that age and how I was always horny.
However, it's been a bit different lately. I've seen him checking out my bulge more, and it almost seems like he's been going out of his way to see me when I'm naked. His mom and I both figured he was likely gay when he was younger, but neither of us ever sad anything about that to him. I've left it alone so he can figure it out for himself.
He's been a bit more of a cuddler lately, too, which has me curious. Usually that goes down as kids get older. At first I just blamed it on his mom not being here anymore, but there feels like some tension. I'd hate to say sexual tension, but it's definitely something not typical.
Last night we were playing that game Twister. In some of the positions, he got a little—too friendly. Like at one point his head was kind of between my legs, and I'm pretty damn sure he brushed his face against my groin. Another time we were almost in a doggy style position, and I could've sworn he pushed his butt up against my groin on purpose. It felt so awkward that I made a joke of it and kind of bounced against him a couple of times. He looked too happy about that.
This has been creating quite the challenge for me as I haven't had sex in a while. Well, at least not with another person. I'm not into dudes and certainly not into my own kid, but, well, he's kind of making me horny.
Things got worse in the morning. He joined me for my morning run. I couldn't help but notice how good his ass looked in those small running shorts. Exercise can often get me pretty horny anyway, so this was a bad combo. When we stopped at a bathroom, I didn't move all the way up so he could get a better view. I watched out of the corner of my eye, and he was absolutely checking my dick out. When I took hold of it and slowly shook it, his gaze was fixed.
When we got home, my head was swimming with horniness. As I sat down to undo my shoelaces, I watched him go into the kitchen to get more water. While he was at the sink drinking, I stared at his small, hot ass through his shorts. I fucking snapped.
Next thing I knew I was walking into the kitchen and moving behind him. As I hugged him, he sank into me. I ran my hands over his torso underneath his shirt and told him what a nice body he was developing. Then I thrust a hand inside his shorts and rubbed his dick over his underwear.
“Dad! That's my penis!”
“I know it is, son.” I felt him getting hard as I kissed his neck.
“Dad?”
“Let's see more of your great body,” I replied. I undid his shorts and yanked them down, then I grabbed his briefs and did the same. I took hold of his growing dick and began running a fingertip over its head. He shivered as I played with his meat and kissed his face and neck. I moved my hands up his body so that his shirt came off next.
I spun him around and took hold of his ass cheeks with both of my hands and massaged them. “Your ass is fucking perfect, and my dick needs to be inside it.”
I guided him a bit more roughly than I meant to into the living room and told him to lay down on the couch. I quickly stripped out of all my clothes before grabbing the lube out of the end table and put a thick coating on my cock. His bright blue eyes were big as he watched me. I climbed over his thin body and gripped my cock as I guided it to his hole.
As soon as I entered him, I knew it was over. There was no turning back. I slowly fed him my cock. I was eager but didn't want to hurt him, so I exerted more control than I ever thought I had. As soon as enough of my meat was inside his ass that I could let go of my cock, I began humping him. 
He's blonde and slightly pale, so it was really easy to see his face get bright red as my rod moved inside him and continued its efforts to get even deeper. 
“Your ass is fucking amazing, Cai!” I said as I began picking up speed and doing deeper thrusts. Soon I was able to lower my face next to his. I licked some of the salty sweat off his face. “This is the tightest hole I've got to fuck!”
After a few moments I slowed down so I could make this last longer. As he seemed more comfortable, I moved a pillow underneath him so it gave me a better angle to work with for his butt. This made it easier to go deeper.
I moved my forearms up more so I could support myself better while doing better thrusting. I took hold of his hands and gripped them as I buried more of my cock inside him. I heard him make a weird noise, and his grip strengthened, but he seemed to be handling this okay.
“You're such a strong young man, Caiden.” I slowed down now. When I would go in more deeply, I would let it sit for a bit before slowly drawing it backward. Then I would slowly feed it back to him. “I know my dick ain't small, and you're taking it like such a big boy. I'm so fucking proud of you, buddy!”
It took a while before his hole felt more relaxed. When I felt him lift his butt up a bit more and moan, I kissed him on the lips before pushing my tongue into his mouth. As we kissed more passionately, I went ahead and sank the rest of my meat into him. He made a noise I could tell wasn't a moan of pleasure, but it didn't really stop him from kissing.
“That's my boy! You got it all inside you, man.” I left it buried and just slightly moved my hips in kind of circles so he could get used to it better. “You're making me so happy.”
Soon I was able to start going faster and doing deeper thrusts. Our bodies would slap together as I started ramming him harder, and as it intensified his moans grew louder. Despite my best effort and desire, my dick took control and I was fucking him faster and harder than I wanted. My orgasm was building because of his tightness.
“Yes! Fuck yes!” I said as the sensation overtook me. Within a few moments, my body was pressed against his as my cock unleashed volleys of cum. It almost felt like I may never stop cumming.
When I could breathe again, we tongue kissed some more. I got off my son and helped him stand up. “Let's go shower,” I said.
He seemed surprised I was taking him to my bathroom. While in the shower, we kissed some more, and I lathered his body with soap and helped him rinse off. As we were getting out, he said “You're hard again.”
I looked down and noticed The General was definitely at attention again. “I can't help it. You have that effect on me.” We tried off, and he sat down on the toilet to dry his lower body. 
A few seconds later I felt his hands on my hips, and he was turning me toward him. I tousled his wet blonde hair, and my pulse rate immediately starting climbing as I saw his open mouth coming for my meat.
His blue eyes blazed into mine as his lips wrapped around my cock. I took hold of his head with my left hand and guided him as he began giving me head. He was starting to go to town on my rod. I put both of my hands on his head and moved it back and forth as I used my hips to face fuck him. He grabbed onto the back of my legs as he picked up speed.
“Yeah, you've been wanting that cock for a while, haven't you, boy? Worship your father's dick! Swallow every fucking inch!” I knew he wouldn't be able to do that last part, but it was fun to say, and it was also nice to hear him gagging as he went down on me further.
I had him work my balls for a bit. As he was getting ready to go back to my meat, I grabbed his hair and pulled his head back. “Tell me what you want.”
“I—I want your—your penis.”
“It's called a cock.”
“I want your cock!”
“Where?” I asked. Lust was really fucking with me right now.
“I want your cock in my mouth!”
I smiled and released him. I grinned even more widely as he devoured my tool. It was so fucking hot to see my little boy's red lips sliding up and down my hard-on, to watch his blonde hair moving back and forth eagerly.
After a while I stepped backward. He leaned forward trying to get my meat again. “You're going to suck my dick later, and you're going to swallow my seed. But right now I need your fucking ass again. Go to my bed.”
I moved aside as he got up, and I followed him to my bed. As he climbed onto the mattress, I lubed my cock again. Entering him again was just so fucking awesome. Once again, it took a while before I get all the way inside him, but once I did I guided him into a position where I was sitting on my heels while he was in my lap. I took hold of his stiff wood and stroked him as we kissed. 
“I never dreamed I'd be fucking you one day, Caiden.” 
“I hope this won't be the last time.”
I moved him into doggy style. I gripped his shoulders firmly as I pulled back my cock and slammed it forward. “No. Fucking. Way. I'm going to need your ass and mouth a lot, boy.”
By the time I came, we were both so exhausted we fell asleep quickly.
When I awoke, I stared at his perfect naked ass. I couldn't believe what was happening. I suppose I should've felt ashamed, but honestly all I could do was smile and feel proud of myself. I slipped some shorts on and went into the kitchen to get some food. Suddenly I was fucking famished!

A couple of days later, he had a soccer game. He played really well, but I was so distracted by looking at his ass through the navy blue shorts. I had to keep thinking of other things that would prevent my dick from growing. At least twice I had to adjust myself so my throbbing erection wouldn't be obvious.
After the picnic, we were driving home, and my cock would just not give up. I remembered a wooded area where I used to fuck his mom, and I headed in that direction. As we were going up the road, he looked confused. “Dad, where are we going?”
“Some place private and safe.”
“Safe?” he asked, looking a bit worried.
“Mmhmm.” 
I parked the car, got out and went to his door. I opened it and told him to stand up. He was looking nervous but followed my directions. I yanked his shorts down and saw his jockstrap. I took him by the shoulders and guided him into the back seat. He lay down, and I noticed that the straps perfectly accentuated his ass. “We'll leave that on,” I said when he went to move the strap.
As I stripped out of my shorts and underwear I gazed at his bare legs hanging off the end of the seat, the white straps from his jock, and the blue and black stripes of his jersey, and it was all just fucking too hot. As I positioned myself behind him, I asked “So, Caiden, what it is you want right now?”
“I want you to fuck me, Dad!”
“Yeah, you want your daddy's cock in your tight sweet hole?”
“Yes, Daddy! I want your cock in my hole!”
Gawd I fucking love this kid! I found some lotion to put on my dick, and I quickly entered him. This was so much hotter being in the car out in the woods. I shoved his jersey up and took my shirt off so we could be skin to skin.
“My dick needs you so bad, son!” I started moving my kick inside his hole.
As I started to pick up speed, he said “Give it to me, Daddy! I want your cock!”
“This may hurt a bit,” I said. He nodded his head he was ready, and I went ahead and pushed my dick forward. His face grew bright red, but he never said anything. 
When my body was pressed against his, I started moving my hips back and forth. After a bit he moaned, and I started going faster. I would pound him for a few seconds then slow down so I could make this last. I alternated between these paces, and it felt amazing.
It was hard to keep under some control as he moaned. That sound almost forced me to ram his ass relentlessly, but I didn't want this to be too quick so I stayed focused.
I loved burying my cock deep inside him and feeling his ass muscles squeeze against it as it remained motionless.
At one point as I was pounding him, his moans got more fervent. I wondered if he was going to cum. Sure enough a couple of moments later I could feel his dick twitching from inside him and he shouted out. His fingernails dug into the seat. I stopped fucking him and moved my hand beneath him. I found his hard meat and took hold of it, and it spasmed a few times in my grip. It was dry, though.
“What was that?” he asked almost breathlessly.
I explained to him about cumming and that he had a dry one.
“That's why you like to fuck so much!”
That made me chuckle. As the twitching calmed down, I went back to fucking him.
It did dawn on me that taking our sweet time during broad daylight out here might not be the best idea, so I went ahead and stopped edging. I let his moaning feed my lust, and soon I was filling his hole with my load.

The next day he had another game since these were playoffs for a championship. As we began driving away, I noticed him removing some clothing. “What are you doing?”
“I'm getting ready for the woods.”
It was hard to drive with an almost completely naked boy sitting next to me. Once we parked, I told him to stay in the car. I came around to his side. “Free my cock,” I said. He smiled and lowered my shorts. He stroked my dick a few times through my underwear before lowering those. I had my shirt off already. Once his lips wrapped around my dick, I had a hand behind his head.
I enjoyed him savoring my meat for a while. At one point he asked if he was going to get to swallow my cum this time. I said no that I was going to fuck him. I had brought a blanket this time, and I spread it over the hood of the car. I helped him and positioned him so that his chest and tummy were on the car, but his legs hung over the side.
I spread his cheeks and stared at his pinkish starfish. I moved my face to his ass and began rimming his hole. His moaning was pretty intense as my tongue pleasured him. I could feel his body squirming with delight. “My son the bottom boy,” I thought.
When I finally entered his hole with my dick, I could slide it in more easily now. It didn't take as long to be buried deep. Soon I was doing deep back and forth thrusting. It was a very different experience to be able to stand while fucking him. I gripped his shoulders so I could drive it in more deeply, and his moans were louder as I humped his hole.
“Yeah, you fucking love that cock, don't you son?”
“Yes, Daddy! I want it!”
I smacked him on the ass before returning to pounding him. I did take occasional breaks between rabbit fucking him. I liked how loudly he moaned when I would pull my dick backward so far it almost fell out (and did at least once) and thrust it back in all the way.
Once again he had a dry orgasm while I pounded him. I wondered if he would have his first actual cumming soon. He enjoyed this so thoroughly, though. And it made me feel like a bit of a stud that I was making him cum without even touching his little sausage.
After I climaxed, we moved the blanket to the ground and lay down on it. I had him remove his jock so we could cuddle naked. He lay on top of me, and I ran my hands up and down his bare body as we kissed. I had to fight sleep since I didn't think it would be a good idea to wake up and find people staring at a father and son cuddling naked. And they might notice a thin white stream running out of his butt.

That night he had a sleepover at a friend's, so it was a couple of days before I saw him again. When he got home, we hugged and kissed. But not as father and son. If you catch my drift. As we kissed, I moved him backward until he sat down on the couch. My hard-on twitched a couple of times which caught his attention. He took hold of my shorts and pulled them down while I removed my shirt.
“It's time for you to worship my cock properly,” I said.
He took hold of the back of my legs as his mouth opened and began making love to my meat. I slowly humped his mouth as he sucked on me eagerly.
He tried deep throating me and made himself cough and gag in the process. He would look up at me a bit sheepishly, and I would just smile encouragement. A couple of times I would push my rod in further and hold his head in place. This seemed to help him discover a way of doing this that allowed him to take more of me down his throat.
After a bit, I grabbed his head with both of my hands and started face fucking him again. I could feel my low-hanging balls bump against him. His fingers dug into my legs as he gripped them for support. He was definitely better than his mom at this. With her I had to just basically lay there while she did a lame job. Caiden loved sucking cock, and that made me fucking joyful.
The alpha side of me really wanted him kneeling on the ground while he blew me, but I didn't feel like he was tall enough to make that work. So this had to do for now. I looked forward to that day, though. And it made me smile when I realized I was fully expecting that he and my dick would be best friends for a long time.
After a while I wanted to sit down, so I stepped back and told him. He got naked while I moved into position on the couch. “I'm not fucking you right now. This is all about you sucking,” I said when I saw him stripping.
“I know. I just like being naked when I'm with you.”
“Well, I like seeing your bare hot ass so that works just fine for me.”
I sat in the corner of the couch,  stretched one leg out and had the other foot resting on the ground. He moved along my leg. When he had returned to my groin, he sucked on my balls for a bit before returning to my hardness. He began by slowly moving his lips down my cock until he couldn't go any further, then he would slowly move backward until just the tip was between his lips. He would move his tongue against it a few times before repeating. It was almost torture being blown this slowly, but it felt so fucking good.
He did this several times before he moved his hands to my ass. He gripped my cheeks firmly as he shoved his mouth down on my cock. He ignored the gagging until his nose was pressed into my pubes.
“YES CAIDEN! FUCK YES!” I said and shoved his head back down after he had pulled it back. “Swallow that fucking cock, boy!” He did it repeatedly a few times.
He kissed the side of my cock while he recovered from the deep throat-induced gagging. I saw him wipe tears from his cheeks. He licked up and down my meat. “Can I suck your dick more often?” he asked.
“Fuck yeah! I hope you never get tired of sucking my cock.”
“Oh I won't!”
“Even when you're older?”
He shook his head no as he went back to slowly devouring my meat.
“What about when you're married?”
“I'm never going to get married. I just want your cock forever.”
I rearranged my position so that my legs were beneath me. I held onto his head with both of my hands again, and I used my legs and hips to help me face fuck him harder. He held onto my ass as I humped his throat.
Soon I readjusted again so his head was pinned against the couch. I gripped the edge while I thrust my dick back and forth in his mouth. No matter what I did, he kept working my cock like crazy.
After a while I figured out how to get him on his knees. I got into a seated position, and he knelt on the floor between my legs. He could still get a hold of my meat and blow me.
We did this for a few moments before I lay down on my back. He lay between my legs while he devoured my rod. As I drew closer to climax, I bent my knees so my feet were on the couch. I grabbed his head and humped his mouth again.
It didn't take much longer before my dick was blasting his throat with my jizz. He swallowed it fervently. When he lifted up his head, he had almost a drugged look on his face. He licked his lips before licking the tip of my dick. He sucked on it some more hoping to milk more from my rod.
After that he climbed up my body and lay on me. I slid my hand between us until I found his dick, and I stroked him until he dry came.
“I never want to be with anyone else, Daddy.”
“Well, you just make sure you never suck another dude or let them fuck you without my permission.”
“I won't.”
“How long have you been wanting that dick?”
He shrugged. “I guess I've been thinking about it for the last couple of years. A lot more lately. I had thought about maybe sneaking into your bed one night and sucking on it before this happened.”
That surprised me a little bit. “Well, no sneaking needed now.”

We went skinny dipping to cool down. He played video games for a good amount in the afternoon and had a friend over. The next few days were a bit rough as he had a tennis camp and was staying there.
On the way home from camp, he asked if we could stop in the woods. “Not this time, Caiden. I want to slow fuck you, and I can't do that in the woods.”
“Can I at least blow you? I can make it quicker if you want.”
As you might imagine, I decided I could manage that. As soon as the ignition was off and my shorts and boxer briefs were down, Caiden's mouth was on my meat. He acted like a hungry man desperate for food. I eased my seat back so I could enjoy it more and so he would have more space. He responded my deep throating me.
He sucked on me zealously until I finally unloaded my jizz into his throat. He swallowed it as if he had been dying of thirst.
When we got home, we headed straight to my bedroom. He undressed me first, then I did the same for him. I had him lay on his back which surprised him. I spread his legs and decided what the fuck. I kissed and licked up his legs until I was at his groin. Then I shocked both of us by going down on him.
He gasped and moaned and almost writhed as I worked his small meat. I did this for a while before kissing up the rest of his body. We tongue kissed briefly before I got off the bed. I grabbed his ankles and drug him to the end of the bed. I flipped him over, his legs dangling off the edge of the mattress. I entered his sweet hole.
It still took a bit for me to get his hole relaxed well enough, but soon I was able to fuck him deep and hard. He moaned loudly as I shoved my dick deep inside him again and again.
After we did this for a few minutes, I had him move back up onto the bed the whole way. He was on his back again, and I lifted his legs and pushed them until his knees were by his head. I slid my meat all the inside him again and slowly humped him like this. We tongue kissed as I fucked him.
Then I had him back on his belly. I would drive my rod in deep and move my body forward trying to get it even deeper. With each thrust he moaned in ecstasy. 
We cuddled again after I climaxed. I had a moment of worry if I would be able to keep up with him once he was a teen and that level of horniness kicked in for him. Well, if anything it's going to be fun trying.
