DENNIS:

    On Sunday morning, while my half-brother Ethan was still sleeping next to me, I decided to look him up and stalk his social media for a while. Lying in bed naked next to Ethan (we'd both taken our shorts off during the night), I picked up my phone and browsed through his photos. He was pretty discreet when it came to social media; he didn't post many pictures of himself, but from the few that he had on I could tell he was very popular with girls his age. I didn't blame them: my brother looked even better in real life than he did in his pics. And just a few hours ago, he'd allowed me to jerk him off to sleep.

    I never expected this to happen on the first night Ethan and I spent together. Throughout my life, I never thought too much about my older brother, but every now and then I couldn't help but wonder what he was like; if he and I would be close if we'd grown up together as siblings. It was too late for that now – Ethan was an adult and I liked to think of myself as a grownup as well. But I was in Pennsylvania now, and there was no telling where my relationship with Ethan might go in the future.

    "Did you and your brother have fun last night?" my grandpa asked me as I went down to the kitchen, wearing a pair of boxer briefs. 

    "Uhh, what do you mean?" I mumbled guiltily.

    "I mean, I heard you guys watching movies late into the night. Did you have a fun time?" Grandpa asked innocently, pouring me a cup of coffee.

    "Yeah, sure," I nodded, accepting the cup and taking a sip. I was tempted to ask Grandpa if he and Ethan had ever done anything sexual together, but I was fairly certain that the answer would be no. Plus, I wanted to keep what happened between me and my brother our little secret for now.

    "I'm gonna go get some groceries today. You boys wanna come?" Grandpa asked next.

    "Uhhh… Well, Ethan's still asleep, and I think I'll wait for him to wake up. You can go by yourself," I told Grandpa.

    "Okay, but I need to go to a few different stores, so it might take me a while."

    "That's fine," I assured him, secretly giddy that I'd get to spend some alone time with my brother.

    After Grandpa left, I went to take a shower and I put on a fresh pair of underwear. I picked a pair of briefs which hugged my ass pretty nicely, and I spent quite a few minutes turning around and checking myself out in the mirror. Finally, after about an hour, Ethan was up. I caught him in the hallway on his way to the bathroom, his hard dick pointing forward like a signpost, erect in all of its morning glory.

    "G– Good morning," I stuttered, swallowing saliva at the sight of my older brother's tool. I'd seen it in the middle of the night in the dark bedroom, but now I was getting a sight of it in the middle of the day, and my reaction was: WHOA!

    "Morning. Is Grandpa here?" Ethan asked with a yawn. Was it normal for him to walk around the house like this when our grandfather was home?!

    "No, he went shopping. Said he might be a while," I answered.

    "Cool," was all he said. He stood there staring out the window into the backyard for a moment. Since he wasn't looking at me, I stole a longer glance at his cock and I could swear it throbbed and bobbed just a little.

    "Um... want some breakfast? Or coffee?" I asked. "I was gonna make some for myself, so I can just double it."

    "Sure, bro. Thanks for that," my brother said, returning his attention to me. "I'm gonna grab a quick shower and I'll be back in a few." With that, he disappeared into the bathroom but didn't fully shut the door. I was tempted to come up with something I needed to get from there just so I could follow Ethan into the bathroom, but I'd obligated myself to make breakfast. As I passed the bathroom I did get a glimpse of his perfect-looking ass as he stepped into the shower.

    I was just getting the food onto plates when Ethan walked into the kitchen, hair wet and dressed in nothing but a very short pair of boxers. I suddenly felt glad that I'd picked the cute pair of briefs. We both were wearing as little as possible, which was sometimes more exciting than being naked. Ethan caught me checking out his body but immediately flashed me a smile that put me at ease.

    "Wanna take this and go eat outside?" Ethan asked as I handed him his plate and coffee. It was one of the first sunny days of spring. I agreed, and we stepped out back and got comfortable on two patio chairs as we slowly ate and chatted intermittently.

    Even though Grandpa's yard was fairly secluded, there were probably a few of the neighbors' widows with a view of us. We were in our underwear of course, but something told me that Ethan would just as easily have come out here naked. We both finished eating fast and we relaxed, sitting quietly with the coffee, which was just the right temperature to balance the slight chill in the morning air.

    "That was fun last night," my brother said after a minute of silence, referring to the handjob I'd given him. I was wondering if we'd address it all or just ignore what happened. I glanced over and saw that Ethan had a friendly expression on his face. His guard was down, and I had the sense that he wasn't the type to do that easily.

    "Yeah, it was fun," I agreed. "I'm glad you were into it."

    "So, do you have a boyfriend or anything?" Ethan asked next, sounding genuinely interested.

    "No, not really," I replied. "I've got a few friends that I have fun with."

    "Over here in Phoenixville?" 

    "Aha," I nodded.

    "Good for you. That's great," my brother smiled. Then he added, "I could tell you know your way around a cock."

    I was unable to stop my sheepish grin. My big brother just told me I gave him a good handjob! Then a question that had been at the back of my mind suddenly found its way to my lips.

    "Have you ever, uh... done anything with Grandpa?" I asked, my tone making it clear I was referring to anything sexual. Ethan laughed and looked both puzzled and intrigued.

    "No. Why do you ask?" he said, looking at me curiously.

    "Just because… you were walking around the house naked… and hard this morning," I said, grinning again and probably looking a little silly.

    "Yeah, well, that's natural," Ethan shrugged."I'm sure Grandpa's seen a boner or two before. If he saw me like that I wouldn't mind," he added nonchalantly. We sat quietly for a bit more. The silence was peaceful and not at all awkward.

    "It's nice out here," my brother observed after a while, closing his eyes and leaning back in the chair. Then, he placed one hand on his bulge and added, "Being in the sun makes me kinda horny. How about you?"

    I felt a rush of excitement when I heard Ethan say that. Feeling bold and encouraged by my brother's chill attitude, I decided to see what he might be open to.

    "Yeah, makes me kinda horny too," I admitted, licking my lips and making a suggestion. "If you want... I can show you what else I can do with a cock."

    "Mmm, be my guest," Ethan said, leaning back and rubbing his crotch for a few seconds, before lifting up his hips to quickly slide off his underwear. His cock was already well on its way to full hardness. I slid out of my chair and got quickly down on my knees in front of Ethan. I placed a hand on each of his thighs and he just sighed softly, spreading his legs apart more to give me space. WIth another scoot forward, my big brother's hard-on was right in front of me. I reached out and started to stroke it.

    For the first time, I was also able to fully appreciate Ethan's balls as well. They were big and his smooth sack hung heavy as I reached around it with my other hand. I made sure to tug gently at just the right moments, timed with the stroking, and soon Ethan was moaning softly.

    I licked my lips, my mouth literally watering at the sight of Ethan's swollen cockhead just inches from my face. It was already leaking clear fluid and I knew I wasn't going to be able to wait any longer. Leaning forward, I enveloped his whole knob with my mouth and began running my tongue all around it. I wanted every drop of that sticky nectar. It tasted even better than I'd imagined it would.

    "Oh fuck, Dennis," my brother moaned, and I felt a shiver run through my body when he put his hand on the back of my head, giving it a very soft push. I slid more of his shaft into my mouth and soon the tip was hitting the back of my throat, which made Ethan moan even louder than before.

    I was sucking my big brother's cock! A week ago I might not have even mentioned having an older sibling if I was talking about my family. And now, Ethan and I were bonding in a way I never thought possible. I wanted so badly to make him feel good, to let him know how much I needed this. So I set about giving him an incredible blowjob, leveraging all my experience since moving here and making my brother squirm with pleasure.

    "Shit, bro... this feels fucking amazing," he sighed as I began sliding his full length down my throat. He was thick and I think if he'd been any bigger I might have struggled with it, but I managed to continue with only a minimal amount of gagging. In a weird way, it felt like I was always meant to reconnect with him at this point in our lives.

    Ethan gripped my head a little tighter with both of his hands, and I relaxed my neck muscles, knowing what was coming next. Going gently at first, my brother began thrusting his cock down my throat with increasing rapidity and force. I knew I could take it and I was able to really lose myself in being a hole meant for his pleasure. I stroked my own hard cock slowly with one hand. I was so turned on that I knew if I got going any faster I'd blow my load. I wanted to try and wait for when Ethan was cumming.

    It felt like that was going to be soon. My brother's nuts were starting to tighten up in my hand. I got the idea in my head that Grandpa could come home at any time and find us like this. I felt sure that Ethan wouldn't even slow down if he saw Grandpa stepping out onto the patio – and I wouldn't want him to. The mental image of being discovered like that ended up pushing me over the edge, and I whimpered around the base of Ethan's cock as I started to cum, finally speeding up my jerking to help squeeze out what felt like a huge load. I began spraying jizz all over the grass beneath the chair.

    A few seconds later, my brother started dumping a similarly massive amount of cum down my throat. He slowly eased up his grip on my head and started pulling his cock out as he was cumming. The last few spurts landed right on my tongue and I was happy to savor the taste of my sibling as I opened my eyes and met his gaze. The tip of his cock was leaving my lips as he looked down at me with a very satisfied smile. His fingers ran through my hair and tugged at it a little as I ran my tongue around my mouth, making sure I got every drop of his thick cream.

    "Goddamn..." Ethan said, reaching down and helping me stand up. Then, he patted my bare ass and said, "You know, next week is spring break for me."

    "Really?" I smiled, a long string of cum still hanging off the tip of my dick.

    "Yeah," my brother nodded. "I was just gonna stay in the city, but maybe I should come spend the week here instead?"

    "You should definitely cum here," I smirked, grabbing Ethan's hand and guiding it close to my asshole.​​
