Bo and I both had to work all day the first Saturday of October and it was an unusual day for us both.

The night before, Bo had used my dildo that closely resembled his cock on me and we jacked each other off to intense orgasms. The feeling of Bo’s “cock” inside me fueled one of the most explosive orgasms I’d ever had.

Earlier that night, I had sucked Bo’s real cock to a throat-filling explosion while using his largest butt plug on his eager ass.

He sent me a photo of his hard, fat cock around lunch time that day. I returned a photo of my own stiff meat obviously in the showers at the gym where I worked.

“Not fair,” he texted back. “You know that’s my favorite place.”

Most of our dates ended up showering and sucking each other off in the locker room or shower at work after hours. It had been his fantasy when we first became lovers. Now it was our regular reality.

“Last night was amazing,” I texted. “I’ll show you just how amazing right here tonight.”

“I can’t wait!”

Bo had a lifelike silicone dildo that was a close facsimile to my dick. We hadn’t used it yet as the last phase of our anal training. The previous night was my first time with a dildo that was nearly a perfect copy of his thick cock. That night would be Bo’s turn.

“I’ve been thinking,” Bo said right after I arrived at his house after work.

That usually meant trouble.

“Can we go to that adult store ourselves?” he asked.

“What for?”

“You got so much cool stuff there last time, I want to see it for myself,” he said.

A quick text to Michael assured me that we could shop at the adult toy store from which our cock rings and butt plugs had come regardless of our age. The cashier probably wouldn’t care since we looked close enough to eighteen.

So, I took Bo to the sex store where his brother Bobby and his boyfriend Michael had introduced me to the joys of cock rings and dildos and butt plugs.

We walked in a little nervously since we were a couple years too young to be there. But the same blue-haired girl I’d seen the last time was the only employee. She smiled at me in a familiar way when we passed the counter.

Bo’s eyes were as wide as quarters as we explored the variety of toys, accessories, and implements designed to enhance sexual pleasure.

To my surprise, the first thing he picked up were silicone ball stretching rings. It was a set of six black silicone rings in various sizes.

“Do you want your balls to hang lower?” I asked.

“I want your balls to hang lower, Daddy. When we get to the main event, I want to feel your balls bang against me.”

“I do like how that feels,” I admitted.

We grabbed two sets of the rings. I noticed chrome stainless steel rings just as Bo caught sight of the cock rings.

“Something makes me think we’re going to need a basket,” I said.

“Something makes me think you’re right,” Bo said, disappearing to the front of the store.

I inspected several of the chrome rings, intrigued by the various sizes and weights and – well, to be honest, how shiny they were.

When Bo returned, I showed him a small one that looked to be something of a beginner size.

“It looks like you need to measure yourself to get the right size,” he said. “The ones we have will stretch and you get six different sizes.”

“Yeah, but –,” I said. “Nevermind. I’ll look this stuff up online and see what I really want. But, for now, let’s start with the stretchy ones.”

Bo darted across the aisle to the cock rings and began picking up and looking intently at several different types. It seemed he had to touch all of them.

“We really don’t need cock rings,” I said. “We have no trouble getting or staying hard. I like our leather rings – and the potential for these ball stretchers. But I don’t think I want anything stretched around just my shaft.”

“I guess you’re right,” Bo said, sounding distracted.

“But, you know what our black leather rings would look good with? Chrome ball stretchers.”

“You’re right about that,” he admitted. “Figure out how to measure for the right size and we’ll come back and I’ll buy my daddy some shiny rings.”

The next thing I knew, he shot off toward the leather bondage products that filled the back half of the store.

He spent thirty minutes exploring and handling almost every piece of leather in the store. He was captivated by the idea of strapping something – anything – around our cocks and balls.

Eventually, he slowly headed toward the front of the store with nothing but the ball stretchers. Then he stopped in the dildos and vibrators section.

He picked up and fondled a dozen or more lifelike dildos of various materials and shapes and species.

“They have horse cock dildos!” he cried out. “And what the hell is this?”

He held up some long, thick tentacle with suction cups.

“Dude, you know there’s all kinds of kinky shit online,” I said.

After checking out a few normal, human-shaped dildos, he finally gave up and headed toward the men’s “clothing.”

Again, he spent quite a while inspecting a dozen or more tiny thongs and g-strings.

“What do you think about this?” he asked about several different pieces.

“It’s not bad if you like it,” I said every time. “But, I prefer we stay naked. The only thing I ever want to wear around you is a Speedo. And even that only when I have to.”

“I guess you’re right,” he admitted. “My favorite outfit on you is skin, Daddy.”

“Exactly. Why should we wear anything when it’s just going to come off in seconds? And we can look pretty sexy in Speedos in public without drawing too much attention. A sheer black g-string wouldn’t work on the beach with your parents.”

“OK. Fine,” he conceded as he finally headed to the register.

Suddenly, something else caught his attention.

“Bo, please, let’s just go get naked somewhere,” I begged. “We don’t really need anything in here unless you want to get some more enemas or syringes.”

That was it. He darted off to find a handful of enemas, tubes of lube, and syringes.

“Now we can go,” he said. “We can’t have enough of these.”

Twenty minutes later, we were in a movie theater with half our high school class. As soon as the lights went down, Bo’s tongue was in my mouth and my hand was groping his cock.

I barely remember seeing any of the movie. But I remember walking out of the theater with my boyfriend’s hand in mine.

“Do you want to go home or to the gym?” I asked as we reached the Jeep.

“Why do you even ask?” he said. “You know my answer.”

After thirty minutes of bathing, fondling, kissing, and caressing each other in the shower at my gym, I pulled Bo down to the floor. He instinctively got on his knees.

After a quick injection of warm lube, I slid his dildo up and down along his slippery ass crack.

When I pushed it between his legs and up against his growing cock, I reached around his waist and grabbed both his cock and the dildo in one hand and began jacking them both together.

He straightened his back and moaned.

“Daddy, that does feel a lot like you,” he said as I kissed my way up his wet back.

“Let’s see how it feels inside,” I whispered into his ear.

I slid back down and pushed my silicone imposter against his waiting ass hole.

I used one hand to spread his cheeks and force his hole wider as I pressed the silicone harder.

Bo responded by reaching back to spread his cheeks and hole for me.

As I started pushing the head of the fake cock against his wrinkled hole I had a better idea.

I leaned forward over his back and positioned my mouth next to his ear. I kissed it a couple times.

“Bo-Bo, would you rather have the real thing instead of a toy?” I breathed into his ear. “Daddy wants his boy so bad.”

“God! Yes! Daddy!” he squealed. “Please fuck me! Please!”

As I pulled back, he dropped his head and shoulders to the floor of the shower so his bare wet and lubed ass was pointed up at me.

I walked forward on my knees until my stiff cock lay over his spread ass crack.

I squeezed the tiny bit of lube that remained in his syringe onto the tip of my head and slid it down his crack to his flesh star.

I slowly pressed against his hole as carefully and gingerly as I had before when I wasn’t ready to fully penetrate. I moved just a millimeter at a time, slowly spreading him open.

This time I had no intention of stopping. I just kept pushing against him until I began to see myself disappear inside my friend.

I knew from previous attempts and teasing sessions that it was tight. But I was unaware of just how tight it would feel when I pressed my entire head into his sphincter, already throbbing with excitement. It suddenly occurred to me that he should have stretched a little with a butt plug before trying this for the first time.

Bo screamed when the fattest part of my cock head passed through his hole. He almost sounded like a girl. But he surprised me by pushing his entire body back toward me, begging for more.

Before I had a chance to react, I was truly balls deep in my boyfriend’s ass for the first time.

“Bo!” I screamed.

“Daddy! I love it!” he squealed. “Fuck me, Daddy! Don’t ever leave me!”

I slowly began pulling back until I was almost out and then pushed back in until I could feel his pelvic bone against my groin.

I continued this until I was pumping in and out of him so fast and hard that everything was a blur and I felt and heard our balls slapping together with every thrust.

It seemed to last for several minutes. But before I knew it that familiar throbbing and quivering began in my abs and cock and legs.

I wanted to stop and enjoy the sensation of my cum flowing through my shaft and out my head. But I couldn’t stop pumping into and against Bo’s olive ass. I held his hips tight as I banged against him over and over until I felt the most intense blast of cum explode from my cock.

It was so strong, I thought it blew my head completely off. Bo even jumped forward when he felt the blast.

“Daddy! Daddy! Daddy!” He was gasping for air like a drowning man.

He reached back between his legs and grabbed my balls tightly and pulled them hard away from my body.

I felt another strong squirt of sperm push into him when he did that.

I dropped on to Bo’s back gasping for air but instinctively kissing his skin. He kept squeezing and pulling my balls.

After what seemed many minutes, I finally lifted myself up and slowly pulled back to release my limp cock from my friend’s gooey ass.

I was covered in lube and cum and saw the same mixture leaking from Bo’s hole.

I showered off quickly before helping Bo up and into the water.

He turned to face me and fell into my arms, his head on my wet chest.

He wrapped his arms around my back as I felt him sobbing against me.

“Bo, what’s wrong?” I asked as I returned his embrace.

“Nothing, Daddy,” he said looking up at me. “That was the most amazing thing you’ve ever done for me. I love you so much!”

We kissed for several minutes before finally heading to the locker room.

We spent the night together in his bed, wrapped in each other’s naked body.

When we woke the next morning, Bo was enraptured. He was more in love with me than ever.

“Daddy, that was so amazing last night,” he gushed. “Why did it take us so long to get to that? What made you decide to give me the real thing instead of the dildo?”

“It just seemed right,” I said. “You were so ready and the dildo was just like me. What difference would it make to play with a toy instead of just loving my boyfriend?”

“Oh, you did love me. That was so –. That wasn’t just sex. I could feel your love in every stroke.”

Bo kissed me passionately all over my face, down my neck and chest and didn’t stop until my cock was in his mouth.

In a few minutes, I blew another load of my thick cum into his mouth and he swallowed every drop before resting his head on my stomach as my dick drooped to its flaccid state.

“How do you feel?” I asked.

“I’m a little sore, I think,” he admitted. “But it isn’t bad. It’s just like I’m stretched out – which, I guess, I am. It’s definitely worse than the big butt plug. But it isn’t bad enough to keep me from wanting it again – and soon!”

“What do you want to do today since we don’t have to work?” I asked as I ran my fingers through his hair.

“Well, we have to try out those ball rings we bought last night,” he said. “But, I really want to spend the day taking pictures of your beautiful body, especially that amazing cock of yours.”

Bo had been taking candid photos of me on his phone all summer and fall. Some were close-ups of my cock and balls in various positions and states of arousal. Some were just portraits. Some were posed like glamour models.

And, of course, there were several dick pics I’d shot of myself and texted to him. I tried to send him at least one a week on the rare occasion when work kept us from spending much time together naked.

Bo only occasionally sent me photos of his fat cock when I withheld my own.

His photography and composition skills had been improving steadily since the early summer.

While he loved creating with photography, my skill set went in a more traditional direction.

I loved drawing and eventually painting. I sketched almost anything that happened to be in front of me when I had the chance. And Bo was in front of me a lot when we spent almost every waking minute together, usually naked.

I had sketched dozens of quick portraits and figures of Bo in his room playing video games, in class, by the pool naked.

My art teacher was thrilled that I had such a willing subject. Of course, she never saw the nudes. Most of her students could only sketch human models in class. With all my practice, I always received the highest grades in class.

By the end of the summer we were trading modeling time like we traded cum. Since we had become so “familiar” over the summer, there was no self-consciousness or shyness whatsoever no matter what kind of poses we tried.

Bo took pictures of me and I drew pictures of him in every conceivable position, in our Speedos, our leather cock rings and new silicone ball rings, and completely naked. We did close-ups of each other’s cocks in every state from flaccid to erect to dripping with cum.

Many times I had him take a quick shot of me holding his cock or him holding mine, or me sucking him, or him sucking me so I could draw it later. I loved turning our relationship into art.

We studied each other so closely, we knew every inch, wrinkle and hair of our bodies. I think I learned as much about Bo’s body drawing him as I did making love to him.

Of course, it’s always gratifying to know someone finds you attractive and sexy, especially someone you also find appealing and desirable. But, being seen as a worthy subject of art is a special honor. And I loved being Bo’s favorite – and only – human subject.

And my friend never stopped raving about the drawings I did of him. He had framed several and put them on his walls. A box under his bed held dozens of nudes and close-ups of his various body parts. As I learned watercolor, Bo was my first portrait and figure model.

I had hundreds of photos of myself Bo took on my phone and laptop. I printed several portraits for display in my room and gave a few to my parents.

On the way home the Friday before Halloween, as he swiped through the hundreds of photos he’d taken of me on his phone, Bo noticed something.

“Daddy, have you noticed your balls getting bigger or hanging lower?” Bo asked, his eyes never leaving his phone.

“I – haven’t really thought about it,” I replied, a little perplexed by the question. “I have been wearing my ball rings almost all the time we’re naked.”

“You need to look at these pictures when we get home,” he said. “It looks like the rings are working for you.”

As soon as we were naked in his room, Bo held his phone so we both could see the screen. He scrolled from one photo from back in July to one he’d taken just the previous weekend. Both showed me sitting in practically the same position on a lounge chair by the pool in the first photo and on his bed in the second. Both seemed to be shot from the same angle and distance. It was obvious Bo had favorite poses.

But it also was obvious that my testicles took up more space between my spread thighs in the more recent photo.

“Hmh,” I grunted. “They do seem bigger. But I don’t think the rings are making my balls bigger. And it should take a lot longer than a month to see any real stretching of my sac.”

We both looked down at my relaxed naked package as I sat on the floor. We looked back at the older photo.

“Send those to me,” I instructed him. “I can open them in Photoshop on my laptop. Let’s see if we can get them close to life-size for a real comparison.”

After some manipulation and very close inspection, it was clear my balls themselves were slightly larger than they had been just three months earlier. It also appeared they were hanging lower. My scrotum appeared to have stretched a little in the short time I’d been wearing the ball stretchers.

“I’ve been wearing those ball stretchers every day since we got them,” I said. “But everything online says it’s a longer process.”

“Maybe it’s because I keep them working overtime,” Bo suggested. “They’re constantly working to replenish all that cum I suck out of you. Exercise does a body good, y’know?”

“Maybe. But, if that’s it, then your balls should be growing, too. You cum at least as much as I do. And you’ve been wearing your rings as much as I have been.”

“Well, I don’t have many photos of myself to compare.”

“No,” I said thoughtfully. “But, now that I think about it, your dick might be growing a little.”

“Really!?” Bo was more than excited at the prospect.

“It seems a little bigger sometimes than when I first started playing with you at the beginning of the summer. I don’t know for sure. But, maybe.”

“We’re probably just still in our adolescent growth spurt,” Bo said. “That can last until we’re sixteen and a half or seventeen.”

“Well, look at you remembering something from Biology.”

“Y’know, now we’re going to have to keep some kind of record of our sizes somehow,” he insisted. “We need to figure out how to keep track, make some kind of chart.”

“We could take pictures or trace outlines of them on paper,” I said. “Or we could just measure them from time to time.”

We settled on taking pictures of our erect cocks next to a ruler. Bo also decided to measure the circumference of my balls with a cloth tape measure and photograph the evidence.

In the back of my mind it seemed a little odd. But the more I thought about it, the more I realized we would have done anything, made up any reason to pay attention to each other’s bodies.

“Y’know, I forgot to look into those steel rings,” I remembered. “I need to do that. I really liked the way they looked.”

“You’d probably look pretty hot in chrome, Daddy,” Bo said, reaching out to caress my balls.

“I wonder if we could find something in leather for you, Hercules,” I purred as I closed in for a kiss.

Just then, we heard Bobby come through the front door, home from college for the weekend.

He barged into Bo’s room and hugged us both without regard for our nudity.

A little later, Bobby caught me in the kitchen.

“Can you give me any ideas for Bo for a Christmas present?” he asked. “I know it’s early. But my parents are asking me if I have any ideas. He spends all his time at school or work or with you. Other than clothes, we don’t really know what he’s interested in anymore. I don’t even know what games he plays these days. Does he need a new game system? We don’t know anything.”

“Photography,” I said immediately. It seemed obvious to me. “He’s always taking pictures with his phone. And he’s got a good eye. He’s taken some really great pictures even with his phone. He could use a real camera to really learn on and grow.”

“That’s a great idea!” Bobby said. “You’re right. I’ve seen him take pictures of all kinds of things ever since he got his first phone. He’s always taking pictures. And the stuff he posts online isn’t just the usual high-school-teenage stuff, either. Perfect! Thanks, Jim!”

“What took you so long?” Bo asked as he waited on his bed stroking his growing cock.

“Uh – well, Bobby asked me what I thought you might want for Christmas?” I replied truthfully.

I sat on the edge of the bed and handed Bo his drink. He took it with the hand that wasn’t engaged with his dick.

“Already? It’s only October. It’s a little early to be thinking about Christmas,” Bo said. “What did you tell him?”

“Well, he said your parents were asking him,” I explained. “But, I don’t know if I should tell you what I told him.”

“You better. You have to,” Bo said. “What if it was a bad idea? You can go correct your mistake so I don’t end up with some bright pink sweater or something.”

“I told him you needed a real dslr camera to use instead of your phone,” I said. “I told him how much you love taking pictures of everything and how great they are – even with a phone.”

“Really? You think my pictures are good? Good enough for a real camera?”

“Yes, Bo,” I said. “You have a great eye for photos and composition – even when you’re taking pictures of me or my dick.”

“You know you’re my favorite subject.”

“That’s obvious. But, Bobby agreed a camera was a good idea and he would pass it on to your parents.”

“That would be great,” Bo said as I took over jacking and massaging his cock.

I leaned down to kiss him.

“You know me better than I know myself, Daddy,” he said between short, sweet kisses.

In a few minutes we both were mouth to groin, licking and sucking each other to throbbing, but loving orgasms.

When we both were spent and sticky, we cuddled together tightly and fell into a deep sleep.
