ETHAN:

    When his spring break was over, my brother Dennis left Philadelphia and returned to Stag Meadow Lane, to live with Grandpa Keith (who, I'd come to find out, was much more of a horny freak than I ever thought). A few weeks passed without me seeing my younger brother. We'd text and keep in touch over the phone, but it just wasn't the same. I mean, we'd just spent two weeks sharing a bed – first at my grandpa's house, then at my dad's apartment – and now we were back to not seeing each other at all. That is why, one Saturday morning, I was very pleasantly surprised to answer the door and see Dennis and Grandpa Keith standing there.

    "What are you guys doing in Philly?" I asked as I welcomed them into the apartment, feeling underdressed since I was only wearing a pair of white boxer briefs, whereas the two of them were fully clothed.

    "Dennis was saying how much he missed you, so I decided to drop by unannounced," Grandpa said. "Hope you don't mind."

    "No, of course not. C'mon in. Dad and Cory are in the kitchen, we were just having breakfast," I said. 

    My father and his boyfriend were both fully naked, sporting some morning wood and making out as we entered the kitchen.

    "Dad! Th– This is a surprise," Uncle Cory stuttered when he saw his father make an appearance. My uncle looked around the room, unsuccessfully searching for some clothes to put on, so he could hide his throbbing boner from his dad. Cory still didn't know that his father was no saint when it came to sex; between the two of them, this type of thing was a total taboo.

    "Morning, gentlemen," Grandpa cleared his throat and went to give my dad a hug first. "Nice to see you, Brandon." 

    As the two of them hugged, my dad's boner hit my grandpa's hip. Next, Grandpa turned to Uncle Cory. Cory stood up and they approached each other slowly, falling into a hug as well. The fact that Cory was naked and sporting full-on wood went unmentioned by either of them.

    "I, uhhh… I better go get dressed," Cory said, quickly turning around so his dad wouldn't notice the fact that he cock was throbbing and leaking precum by this point. "I… I'm spending the day with the kids today, so I need to pick 'em up."

    As far as I knew, Cory still had over an hour before he had to go pick up his kids, but he got ready and left the apartment in a rush. I made more coffee for Dennis and Grandpa, and the four of us sat around the table with my dad, discussing the past few weeks since we'd seen each other.

    "Ready to go back to Texas?" Dad asked Dennis.

    "Kinda. But it's been decided: I'm coming back in the fall," my half-brother announced happily.

    "His GPA is higher than it's been in years," Grandpa said proudly.

    "And I'm gonna study to get my driver's license this summer," Dennis bragged. "So when I come back I can drive down to the city and see you anytime."

    I smiled, suspecting my brother was looking forward to coming to Philly to go cruising just as much as he was looking forward to seeing me. Of course, he now had some other buddies here as well, in my father and uncle. I'd miss Dennis over the summer but that would only make the fall all the more exciting.

    A few hours later, the four of us were driving to lunch. Dad was taking us to his favorite diner, a place I'd been plenty of times. The vibe was kinda hip and gay, a place where Dad, Cory and I had all been hit on in the past. We were seated at a booth right away, despite the fact most people had to wait for a table on this busy Saturday. As we got a few unfriendly glares from people who'd been there longer, I also noticed the flirty eye contact between Dennis and the waiter who was the one to seat us. Was our VIP treatment courtesy of a past hookup between Dennis and this guy? 

    When the same waiter arrived to take our orders later, the flirty banter between him and Dennis was on full display.

    "It might be a little too crowded today for your taste," the waiter said as he gathered up the menus and stepped away, shooting Dennis a wink before heading back behind the counter. I was left wondering what that meant.

    "Have you been here before?" I asked my brother.

     "Yup," Dennis replied gleefully. "This is the diner where I sucked Uncle Cory off for the first time."

    I happened to be taking a sip of my water right at that moment, and I almost choked while laughing out loud. Dad's eyebrows shot up; he was clearly surprised that Dennis would say something like this in front of Grandpa Keith. But our grandfather seemed the most stunned out of everyone.

    "You– You did?" Grandpa asked in astoundment. While there was no way he was shocked to hear that Dennis was sucking a cock in public, he was taken aback to hear that the cock in question belonged to his son.

    "Yeah. Just ask the waiter. He saw us," Dennis said with a smirk, nodding his head again toward the flirty waiter. 

    My Dad looked at me like he wasn't sure what to think. To him, talking about our incestuous sex lives in front of Grandpa Keith was completely new. I figured the best way to break the awkward silence was to put as many cards out on the table as possible. So, I turned to my brother and said,

    "Well I'm sure it was just as good as the blowjobs you gave Grandpa and me last time I was at Grandpa's house."

    Dennis just smiled and blushed a little. Grandpa turned a deeper shade of red, though a smirk found its way to his face as well.

    "Keith... you dirty dog," Dad finally said, grinning just as much as I was. "No wonder Dennis showed up hornier than all hell when he came to Philly."

    "Now, Brandon," Grandpa began, acting coy. "Dennis was getting to know the neighborhood boys very well for a good while before he and I… had some fun for the first time," he added diplomatically. 

    Everyone seemed to reach down to adjust their bulge at the same moment, and we all noticed it. This conversation was clearly making everyone horny.

    "Too bad this place is so busy," I mused, looking around at the very full establishment. "Dennis could have shown us just how he managed to suck Uncle Cory's dick here." Suddenly, there was a hand on my crotch, and I realized it was my brother's. He'd managed to reach over without even moving his upper arm, so from above the table it looked like nothing suspicious was going on. He gave my bulge a good squeeze before pulling his hand away.

    When the waiter came by to let us know our food would be ready in a few minutes, Dad looked at all of us and then told the man we'd decided to take everything to go.

    Back at the apartment, there weren't many words spoken once we all got inside. All horned up, Dennis was quickly on his knees in front of Grandpa, and Dad and I spent the next few minutes watching my brother suck the older man's cock. My father seemed especially fixated, even as he stood behind me and ground his hard cock against my ass through our clothes.

    After a while, Dennis came up for air and then turned around and smiled at us, holding Grandpa's hard, wet cock in his hand. I was surprised when my father stepped out from behind me and moved toward them. He pulled off his shirt and I watched the muscles of his back tense as he got on his knees next to Dennis and glanced up at my grandfather. They had a wordless exchange, and then Dad's mouth was slurping up Grandpa's cock.

    Sensing that his services weren't needed for the moment, Dennis stood and walked over to me, sliding his pants off as he moved. We embraced one another and began to make out vigorously. As we kissed, my hands moved to Dennis's ass and got to squeezing those perfect glutes. I gradually worked my fingers into the cleft between them, and loved hearing my brother's soft whimpering while we continued to kiss and I played with his hole. Using fingers from both hands, I started to open him up. He was loving it, wiggling his ass in an attempt to get my fingers deeper inside.

    I eventually had the first two fingers from each hand in him, down to my second knuckles. His hole was relaxing now, letting me open him up. Suddenly, I felt a slippery cockhead moving into the space my fingers were widening. I paused our kissing and opened my eyes to see Grandpa standing right behind Dennis, pushing his cock in. My dad was a few steps away, jerking his throbbing cock while he watched. 

    I returned to kissing my brother and slowly withdrew my hands as our grandfather's cock replaced my fingers in Dennis's hole. My brother sighed while Grandpa pushed in further. Dennis pulled his lips from mine and buried his face in my chest. I held him for a minute, until our grandfather's cock was balls-deep in Dennis's ass. Then, I slipped away and let my brother brace himself against the wall I'd been leaning back on. Dennis wanted to be ready when Grandpa starting fucking him hard, which would probably be starting at any moment.

    I went to stand next to my father and we stroked one another's cocks as we watched Grandpa and Dennis. I could tell Dad was really turned on, and it was hot to feel his cock throbbing so much in my hand. I started to drop to my knees, intending to suck a load out of him as he watched my grandfather fuck my brother. But, as I went to kneel, Dad grabbed my arms and pulled me back up to a standing position. He looked at me briefly and then reached his hand behind my head and pulled me into an intense kiss. Then, he stepped back from me, and he went to stand next to Dennis facing the wall. Dad leaned forward and poked his ass back toward me, clearly sending the message that he wanted to get fucked, just like Dennis was.

    My cock swelled up a little more as I stepped up behind Dad. It had been a while since I'd fucked him, and it felt extra exciting to be doing this right next to Dennis and Grandpa. There was an explosive energy in the room, and I thought about how Grandpa had known my father for years before I was even born. They shared so much history and yet they were seeing brand new parts of one another for the first time today, both literally and figuratively.

    As I eagerly pushed my cock into my father's tight asshole, I saw Grandpa glance over and watch us with more than a little awe. Even though he was in the midst of nailing his own grandson, it must have been mind-blowing to watch me fucking my own dad. I made sure I gave him a good show as I thrusted back-and-forth forcefully.

    Both Dad and Dennis were pressed up against the living room wall and loving the pounding they were getting. I noticed them both scoot toward one another so that their shoulders were touching. There were moans, grunts and deep sighs happening all around. I was starting to sweat, and when I looked at Grandpa I knew he was going to nut soon. I made sure to get myself to the same place, right on the edge, so we could make this a simultaneous double breeding.

    Dad squeezed my cock with his ass in an intense way, and I ended up losing control a little earlier than I had planned.

    "Oh shit. Grandpa... I'm cumming!" I cried out.

    "I'm right there too, Ethan," he gasped, and our shoulders pressed together in that moment as well. His skin felt both soft and hot against mine.

    We both emptied our balls into the family members we had pinned up against the wall. My grandfather stopped thrusting, leaving himself buried balls-deep in my little brother as he filled Dennis's guts with the seed that had ultimately given rise to us both. I kept slamming in and out of my father's ass while I came. It felt too good to stop, he was so tight and my cock was able to go faster as my jizz lubed up his insides.

    Eventually, Grandpa and I were both spent and we slid our cocks out of those used holes at the same time. We looked at one another and smiled, embracing as we pressed our slick, dripping cocks between our bodies. As I watched my father get on his knees behind Dennis and start eating out my brother's gaping hole, I couldn't help but wonder what Uncle Cory was going to say when he eventually found out what he missed today.
