KEITH:

    After a few weeks of living with me on Stag Meadow Lane, it looked like my grandson was adjusting quite well to his new environment. His grades at school were decent (certainly better than his grades back in Texas) and he seemed to have made a few friends, primarily the triplets next door. And yet… there was a gnawing feeling in my stomach that there was something big Dennis was hiding from me.

    Fair enough, every single teenager hides plenty of things from their family. But given Dennis's past, a part of me was worried every time he left the house – which was a lot these days. Even without a car, he managed to find a way to get around. Apparently, the neighborhood triplets had several bikes they weren't using, so they let my grandson have one of them. Then earlier tonight, when I was driving past the local bus stop, I noticed Dennis's bike chained up against a nearby fence. Dennis was nowhere in sight, which led me to believe that my grandson had cycled to the bus stop and gotten on the bus to go god-knows-where. That didn't sit right with me. To make matters worse, Dennis didn't return to the house until 11 o'clock at night.

    "Where were you?" I asked him when he finally got home. Normally, I'd be in bed by this hour, even though it was a Saturday. 

    "Just hanging out with a friend, jeez," he said, trying to walk away from me and head up the stairs.

    "Not so fast! What friend? Do I know them?" I shouted sternly.

    "Yes, you know them from school, but I'm not gonna give you any names because it's none of your business!" Dennis shouted back aggressively. "For fuck's sake, what do you want from me? I do all my homework, my grades are up. I'm 16, not six. Lay the fuck off me!"

    With that, Dennis stomped up the stairs and slammed the door to his room. Normally, I would agree that a 16-year-old deserved some freedom, but in Dennis's case I just couldn't let him do what he wants. After all, I was his final stop before being sent to military camp by his parents if anything happened. 

    For now, I decided to let Dennis sleep off his anger. The following day, I waited at the kitchen table for him to come downstairs so we could have a chat. Shortly before noon, my grandson finally showed up. Surprisingly, Dennis was almost naked, wearing nothing but a pair of tight blue boxer briefs. The boy didn't usually walk around my house in his underwear, but I suppose after some time here he was growing more comfortable.

    "Good morning. Want some coffee?" I did my best to sound as friendly as possible. 

    "Sure," said Dennis. He helped himself to some caffeine and breakfast, and about ten minutes later I decided it was time to get to the crux of the matter.

    "We need to talk about where you were last night," I said calmly.

    "Erghhhh, this again?!" Dennis rolled his eyes. "I told you, I was hanging out with someone from school."

    "And why won't you tell me their name?" I asked.

    "Because I don't wanna lie!" Dennis said loudly. "Okay? It's a guy, and we met up to… do things. Like, hook up. And I don't wanna out him to you cuz it's none of your business."

    I was speechless. I was NOT expecting this. I knew that my grandson was into guys, but we'd never explicitly addressed the issue. Was this Dennis's coming-out moment? I wondered how to react; whether to ignore it or assure him that everything was okay.

    "I understand," I said coolly before asking, "Is this guy your boyfriend?" 

    "No, just one of the guys I hook up with," Dennis blurted. Then he added, "Shit!" That information had slipped out of him without him meaning to say it.

    "Okay, so you hook up with multiple guys. That's okay," I said. "Is everything… going okay with all of them?"

    "Yes, Grandpa, everything's going fine with my fuck buddies. Now what else do you got to ask me?"

    I could tell Dennis was being crass on purpose, probably trying to shock me and get me to stop asking questions. I couldn't blame him; I was the one who had pressed the topic. 

    "Okay, well… if you have any questions…" I said in an attempt to be helpful.

    "I'll come to you, sure," Dennis rolled his eyes again.

    "Do you have any plans for today?" I changed the topic.

    "Yeah, the triplets are dropping by soon. Their mom is cleaning out their basement today so we're gonna hang out here for a while."

    An hour later, there was a knock at the door. Before I could even get up from my chair, Dennis was bounding down the stairs, two at a time, and heading to answer. He was already opening it before I even processed that he was still dressed only in the pair of boxer briefs. That surprised me, but then again maybe it wasn't unusual for them to all hang out that way down in the triplets' basement. I certainly knew that Finn and Dennis were comfortable enough with one another, and I noticed that Finn was the first triplet Dennis greeted with a hug. 

    Wyatt and Mason didn't seem surprised to see my grandson in a state of near nakedness. All three young men greeted me politely, and then the whole troupe vanished upstairs and I heard Dennis's door shut.

    I watched TV for another twenty minutes or so, but grew bored and thought I'd go grab a book from my upstairs office. When I started up the stairs I heard some faint sounds echoing through the hallway, and as I ascended they got louder and more recognizable. It wasn't laughter like I'd assumed at first... there was really no mistaking the sounds of sex; even sex where the participants were clearly trying to remain quiet.

    As I passed Dennis's door, I slowed my pace, and I could make out several people breathing heavily. What was going on in there? I already knew that Dennis and Finn traded blowjobs, and I certainly had no problem with that. But was Dennis active with all three of the brothers?! Were they all messing around together in the bedroom, right under my nose? Dennis did say he had multiple "fuck buddies"… Unsure how I should feel about the possibility, I continued to my office, shut the door and sat down at my desk, thoughts of finding reading material now forgotten.

    Unable to squelch my curiosity about what the boys were getting up to, I reached for my tablet that was charging on the desk. Opening up the security camera app, I steeled myself for what I was about to see, though I had to admit I felt that same lurid sense of excitement rushing back to me that I'd felt when spying on my grandson with Finn. My cock was also stirring in my pants, and I held my breath as I called up the feed from Dennis's room.

    I let that air out in a gasp when I saw my grandson on his hands and knees on the bed, with Mason right behind him, dick buried in Dennis's ass. The young man was fucking my grandson at a rapid clip, with his eyes closed and head cocked backward, a look of bliss on his face. Dennis had his head bent down between his forearms, and for a moment I was concerned that he wasn't exactly a willing participant in this. But then he lifted his head up and I saw there was a huge smile on his face.

    Feeling some relief, I took a moment to notice that Finn and Wyatt were also naked, with the quarterback standing at one corner of the bed, slowly stroking himself, while his brother stood at the other end, near Dennis's head. I saw Finn reach out lovingly and stroke my grandson's hair and neck. It was heart-warming for a moment, until he stepped forward and unceremoniously shoved his hard cock into Dennis's mouth. My grandson seemed surprised but not at all bothered, and for the next few minutes I watched Dennis taking it from both ends like some kind of hardcore porn star.

    Blown away as I was that I was watching some of my high school students engaging in a foursome, the images I was witnessing were also having a definite effect on my cock. It was harder than I'd felt it in a long time, and I didn't stop to question myself as I slid my pants and underwear off and spread my legs to begin stroking. I had no idea what more I was going to see play out on the screen in front of me, but I knew for certain that I was going to blow a load watching it. I'd worry about the ethics of all this later. 

    There was a change in the energy – less action and more talking amongst the boys – and I found myself wishing that I could hear what they were saying. I realized a few seconds later that Mason had finished off inside my grandson. He was slowly climbing off the bed, cock flopping around as he moved, still dripping from the tip. Finn wasted no time in pulling his cock out of Dennis's mouth and stepping around to the other end of the bed. A second later, he was fucking my grandson just like his brother had been.

    This time, Dennis was opening his mouth, and even through two closed doors, I could make out the loud sound of my grandson moaning. He knew I was home and I had to wonder if he was truly unaware of how loud they were being, or if he knew and just didn't care. Or if he actually wanted me to hear him essentially getting passed around by our three neighbors.

    I noticed Mason stepping over to where Finn had just been, and then I gasped out loud when Dennis started sucking on Mason's cock -- the cock that had just been up his own ass! I didn't stop stroking myself for a second, though. And I wondered how much sex these four had been having. Was this what Dennis was always out doing? Or were there still more young men that my grandson was servicing around town?

    The thought that I might have unwittingly allowed Dennis to become some insatiable... well, I wasn't even sure what word to use. Slut? Whore? I felt a surge of guilt, but it was mixed with a thrill of transgression. It had always been a special thing to spoil my grandson when he was little, letting him do things that his parents might disapprove of, like drink soda or stay up late. Was this the same thing? I knew he wasn't getting hurt, after all. Hell, maybe I was actually being a good guardian by spying on his activities like this, making sure he was okay.

    More changing of positions on the screen brought me back out of my thoughts, and I watched Mason walk over to stand near Wyatt. It looked like Finn was coming up on his big moment now, and I figured the last triplet would get his turn after that. I gasped even louder when I saw Mason bend down and take the quarterback's cock in his mouth, with Wyatt moving his hand to the back of Mason's head to guide it all the way down his shaft. The hunky football player was getting a blowjob from his brother! Holy shit!!

    Dennis had his head buried down between his forearms again, and so wasn't aware of the incestuous dick-sucking happening just a few feet away from him. It seemed like Mason was simply getting his brother's cock ready for Dennis's ass, because he stopped suddenly when Finn stepped back from the end of the bed. Apparently Finn had blown his load while I was awestruck by what his brothers were doing. Finn made room for Wyatt, who then became the third brother to sink his cock into my grandson's ass within the last twenty minutes.

    Knowing that I wanted to blow my load at the same time as my school's star athlete, I picked up the pace of my stroking. I noticed that Dennis had one hand between his legs and I could tell he was jacking off too. What must his ass feel like right now? Was he enjoying it? It sure seemed like he was. It certainly hadn't escaped my notice that the triplets were quite well-endowed, and I supposed that I was a little impressed by my grandson's stamina.

    Wyatt let out a yelp and then swatted Dennis's ass pretty hard, enough where I thought I heard the slap echo out in the hallway. I watched as he did that several more times, and then stopped thrusting when he was all the way inside my grandson. He pulled Dennis's hips close to him and looked like he was in heaven. I wondered how an ass must feel with two loads already inside it. From what I could see, it was quite an experience.

    I began to spray a load all over myself, wishing too late that I'd thought to unbutton my shirt. Feeling overwhelmed by what I'd seen, I just let myself get lost in all of it while the jets of cum continued shooting from the end of my dick. I couldn't remember having an orgasm like this recently, even when I'd been watching Dennis and Finn previously. Today's cam show was way more intense (and I supposed Dennis could say the same thing).

    As I recovered, I watched the boys pull apart from one another, with Dennis tossing each of them an article of his clothing they could use to clean themselves up. Dennis himself slid his boxer briefs back on while the other three got partially redressed. After a moment, they were all reclining somewhere in the room while looking at their phones. Back to being regular teenagers, it seemed. I shook my head in disbelief.

    After cleaning myself up, I ended up grabbing a book after all, and relaxed on the couch in my office, already feeling like what I'd seen had been an odd dream. Later, I heard Dennis's bedroom door open and four sets of feet gallop down the stairs. That was followed by audible goodbyes and the front door closing.

    A minute later, there was a knock at my office door and then Dennis stepped inside, still just clad in his boxer briefs.

    "They just left, and um... I'm gonna take a shower," he said. "Are we still going to order pizza?"

    "Yeah," I said. "I'll call in the order in a minute."

    "Great!" Dennis said, "I'm starving!" He turned and left the room, not bothering to close the door behind him. As he headed toward the bathroom, I noticed a wet spot on the back of his boxer briefs – and I knew immediately it was the triplets' cum.​​
