ETHAN:

    Showing my little brother around Philadelphia during his spring break was lots of fun, and I think Dennis enjoyed it as well. I skipped a couple of classes to be with him but there were still times when I had to leave Dennis to his own devices so I could attend a lecture. I don't think my brother had a problem with that, however. This was his first time staying in a big city and being the slut that he is, he was overwhelmed by all of the cruising opportunities. He got on the apps and whenever he was alone, Dennis went off to a cruisy park or public bathroom. I went with him a few times as well, wanting to supervise him and make sure he was okay. Dennis and I found ourselves sharing a dick at a gloryhole; as well as getting our cocks sucked in the park by an eager college freshman who didn't know we were half-brothers until after he'd swallowed both of our jizz.

    On Saturday, Dennis was slowly getting ready to go back to our grandfather's house on Stag Meadow Lane.  He would spend a few more weeks there until summer, when he was set to return to Texas.

    "Will you come down and visit me over the summer?" Dennis asked me keenly on Saturday morning. We were both naked in my room, and my brother was folding and packing his clothes into his bag.

    "I'll do my best," I promised. "I gotta get a job, so I'll be busy. But I'll try to come down for at least a few days."

    Dropping his bag on the floor, Dennis walked up to the bed and gave me a big hug. Then, he pushed me down onto the mattress and began wrestling and tickling me. I played along, until I finally came out on top and had my brother in a chokehold, gripping him tightly until he finally surrendered.

    "What do you wanna do today, after you're done packing?" I asked. "Do you wanna drive straight to Grandpa's house or hang out here for a while?"

    "Let's go back to the park," Dennis suggested with a smirk. "You know, the park where that guy sucked us off?"

    "You're fucking insatiable, you know that?" I rolled my eyes and chuckled – although, admittedly, I was feeling quite horny as well and would gladly welcome a blowjob.

    Unfortunately, right after we arrived at the cruisy park, the weather decided to turn on us and it started raining. We ran into a nearby coffee shop for shelter, and my brother offered to suck me off in the bathroom since he could tell I was desperately in need of release by this point.

    "I have a better idea," I said. "Let's go back to the apartment and spend all afternoon fucking. Then, I'll drive you back to Grandpa's house."

    "Sounds like a plan, bro," Dennis smiled, giving my bulge a squeeze under the table. 

    A short Uber ride later, we were back at the apartment where my dad and Uncle Cory were hanging out naked in the kitchen. 

    "You boys back already? Changed your minds because of the rain?" Dad asked.

    "Yeah. We'll be in my room if you need us," I said, holding Dennis's hand and pretty much dragging him to my bedroom. I heard Dad and Cory chuckling as a day's worth of sexual buildup overtook both of us. Dennis and I were making out before the bedroom door was even closed, and it seemed like only seconds later that our clothes were off. The electricity between was as intoxicating as it had ever been. It was different from the connection I had with Dad, even though he and I had practically grown up as brothers. With Dennis... it was like we were magnets that had spent years apart and were now powerfully drawn together.

    When he swallowed my cock it felt so perfect, just like it did that first time at Grandpa's house. He was a gifted cocksucker and I knew he loved mine most of all – he'd said as much. And it was only fair, since I'd realized I felt the same way about his ass. For that reason, I couldn't resist pulling his head off my cock and flipping him over onto the bed, then sinking my dick into his hole with a loud growl. In these intense moments, it felt like we were animals, operating only on our carnal instincts.

    I knew we were noisy, but luckily it didn't matter in this apartment. In fact, it wasn't long before I started hearing similar sounds coming from the other side of the thin wall. My father and uncle's bedroom was seeing some action as well, by the sound of it. That was no surprise, since they were both constantly horny just like Dennis and I were and it didn't take much to get any of us going. It sounded like Uncle Cory was taking it up the ass just as hard in that room as Dennis was in this one.

    After a while, it became clear that Dennis and our uncle were thriving on one another's shouts and moans, almost like they were competing for who was the more verbal bottom. It was wild, and only made me want to fuck my little brother even harder. Dennis's ass felt so nice and tight, I got close to cumming several times but I held back, intending to prolong this fun as long as possible.

    There was a point when I realized we weren't hearing noise from the other side of the wall any longer. They definitely hadn't finished, I would have at least heard my father bellowing as he busted his nut. I was starting to wonder what the deal was when suddenly my bedroom door burst open and Dad and Uncle Cory strutted in, smiles on their faces and hard dicks swinging with each step as they approached.

    Immediately, Dad pushed Cory onto my bed, right next to my little brother. Next, Dad shoved his cock back inside Uncle Cory's ass, and they resumed their fucking without missing a beat. Dad and I were now shoulder-to-shoulder, as were Dennis and my uncle, and the heat between all of us was almost overwhelming. The two bottoms started making out as they got railed, and soon Dad and I were doing the same. It might have been hours that passed that way, or just minutes, I completely lost track.

    Eventually, I had to step back from Dennis's ass and grab some water from a bottle on the dresser. Within a few seconds, Cory had managed to maneuver himself behind my little brother and slide his cock into the gaping hole that had been vacated by my dick. Dad's dick never left Cory's ass the whole time, and the hard fucking resumed again, now with my uncle in the middle. His moans were definitely louder than Dennis's this time, though it was close. My brother was being fucked with double force now, and enjoying it quite a bit judging by the almost constant moans of pleasure I was hearing.

    Though I didn't necessarily want to silence that, my dick was already longing to be back inside him as I took another swig from the bottle. So after I set it down, I stepped around to the other side of the bed and fed Dennis my cock. He gladly accepted it down his throat, tasting his own ass sweat on my prick.

    The four of us kept going like that for a while. Then, after whispering something into his boyfriend's ear, Dad pulled out and stepped back, with Cory doing the same a moment later. My uncle moved around and got into position next to me as my father slid his dick into Dennis's eager ass and got right back to it. I smiled as I watched Dennis pull his mouth off my cock for less then a second and rapidly slurp down Uncle Cory's cock for a moment. Cory sighed and looked at me with a satisfied expression, and I leaned in and kissed him, my hard shaft slapping against my brother's face.

    A fun idea struck me, and after a minute more of wrestling tongues with my uncle, I got onto my back and slid underneath Dennis until his dripping cock was at my mouth. Angling myself in the best way possible, I opened up and let my father's thrusts push my brother's dick down my throat. Dennis was moaning loudly around our uncle's shaft and I could feel the precum oozing from my brother's cockhead. His pleasure centers were in overdrive, and it didn't surprise me to feel his cock start to pulse in my throat less than a minute later. Dennis began shooting his teen load and I slid back a little so that I could taste it more before swallowing it down. I found myself wishing I'd sucked my brother's cock more often these past few weeks, and made a mental note to work on that more when I visited him in Texas over the summer.

    Once I finished swallowing my brother's creamy seed, I released his cock and repositioned myself underneath him once again, managing to slide my legs in between Dennis's as well as my dad's, with my face looking right up at Dennis's lips wrapped around uncle Cory. My father seemed to understand what I was trying to do, and I felt his hand on my hard shaft, maneuvering it into position as he slowed his fucking. Dennis moaned even louder around Cory's cock as the head of my dick began to push inside him. His hole was already stretched tight around the thickness of my dad's shaft, but I was able to slide in slowly, inch by inch. Dennis started to go limp from everything that was happening, and I wrapped my arms around his torso and let him rest his weight on me. That helped him relax a little and I was able to push the rest of the way in just as Dad started thrusting again.

    "Oh fuck," Cory cried out, and then I was both surprised and pleased to feel Dennis's lips against my own. We started making out as our uncle's seed began to spray across both our faces. It was so hot to lick little globs of his load into our mouths as we kissed, tasting some of the DNA we both shared.

     We were still doing that when Dad and I started to cum, almost at the same moment as one another. We flooded my little bro's ass with jizz and it quickly began oozing out around our shafts and dripping down, making my nuts a sticky mess. I felt a tongue moving around down there and I knew Cory had moved and was now doing everything he could to clean that up. When my father pulled his cock out, I heard my uncle slurp it down, no doubt eager to get every tasty drop of the juices that he could. I decided to leave my softening dick inside Dennis for a little while longer, as we kept kissing. We didn't have that much time left to enjoy each other and I wanted to make every second of it count.
