Well, before starting my story I'd like to introduce myself. I'm Connor, a 20 year old college student. Even though my body is not all muscular I do work out from time to time. I’m not a tall person- like, 1.80cm-ish. My boyfriend is Jack, he is23 and he like a huge muscle-bear and we have been together for 3 years. He is 1.92cm, and has a huge muscular body with a little bit of fat. He is like covered in fur, which I love a lot to be honest. His dick is 18cm, thick. I always have a hard time taking it but that’s the fun part for me, the challenge. Last but not least, my brother, Lucas. He turned 18 a few months ago and he was gonna start college a week later. He is “the twink”. He is short, hairless, and skinny, though he always claimed that he is straight. He was a shy kid and never had a girlfriend before but we believed him as there is no reason for him to hide himself. Even though he is a shy kid, he was always close to Jack and that made me happy. I was happy to see my brother getting along with my boyfriend. So, to congratulate him for college we decided to take him camping. He loves nature, and we needed a break from the city, and he accepted. As my parents know my boyfriend well, there was no issue with this. We had only one tent, so we were all gonna sleep in that but it was fine with us.When the day came, Jack came to our house. He looked ready for camping. To be honest, this was my first time so I left everything to Jack, he handled it all. I brought a lube in case we needed it and it was full, so we could have fun freely when Lucas swims. Normally, according to plan Jack was gonna drive the car, but he told me that he is really sleepy so I agreed to ride the car. He sit right behind me so I couldn’t see him but it was OK, I needed to focus on the road. I was hoping that I could talk with my brother, but Lucas told that he is sleepy too so he sat back. Luckily, the drive was not long, like two hours maybe. When I looked back, I saw that Lucas was lying and I couldn’t see his face. I guessed that he put his head on Jack’s lap. I was fine with it though, he was my little brother after all.
After like 15 minutes I thought the smell got kinda changed. I could’ve sworn that it smelled like cum, it was like… a nice smell to me. When my boyfriend cums in his boxers and makes me smell it after, that’s how the smell was. I thought maybe one of them scratched their crotch and the reason for the smell is that but I still looked back again. My boyfriend was sleeping but I couldn’t see his lap though I saw that Lucas had a boner but I try to focus on the road again. It was empty but I couldn’t take any risks. After like 10 minutes, I heard panting noises. I checked Jack again. His eyes were closed but he was smiling. I thought about some things but I didn’t want to believe so I focused on the road again. Only half an hour was left. When we arrived, I woke them up and it was like nothing happened, so I thought I maybe dreamed the voice. We found a nice spot next to the river and Jack told us that he can handle the tent, but we need to find wood and sticks for fire to cook marshmallows at night. Lucas and I started searching for wood. We weren’t really far from the river but I lost Lucas for a few minutes. I panicked but before shouting for him I saw him hiding behind a tree. Jack was pissing in the river and Lucas was watching him. I got shocked and couldn’t move for a while, but before Jack was done he looked to our way and I immediately hide. I didn’t know how to act or speak. My brother was watching my boyfriend piss! That was not all. When Jack saw Lucas, he made a sign for Lucas to come, and he did! Lucas went next to Jack and my boyfriend pushed his head, making him sit on the ground. I was still hiding behind a tree, watching them secretly. He told Lucas something. I couldn’t hear but I saw his mouth moving, and after Lucas opened his mouth, and Jack started pissing in my brother’s mouth. I couldn’t believe my eyes. When Jack was nearly done peeing, Lucas stared sucking Jack’s dick and Jack pushed Lucas’s head all the way to his pubes. As I like him hairy, he hasn’t shaved for months and it was like a forest there. “So… that was the smell in the car” I thought. Lucas must’ve sucked his cock in the car too, while he was sleeping. I saw Lucas closing his eyes. He was sniffing my boyfriend’s pubic hair while jerking off to himself. This must made my boyfriend hornier because he stared face-fucking my brother, making his eyes watery. I could hear Jack’s huge saggy balls hitting my little brother’s face. While watching them in shock, I realized that my dick has never been this hard. I wanted to jerk off so bad but when I was gonna start Jack started to cum in Lucas’ mouth. Lucas got up and Jack smacked his ass and said something. I went back in the forest as I didn’t want to get caught but I could never forget what I saw. A few minutes later Lucas came to me and I asked him why his eyes were red like he cried, and he told me that he accidentally swallowed his saliva so he started coughing a lot. I acted like I believed him I knew the real reason is my dear boyfriend fucked my little brother’s mouth. We went back to the tent with what we’ve collected. I saw Jack and he hugged and kissed me, saying that he loves me a lot. I believe him, but I also know that he wants other asses and mouths to fuck. We sat next to the river and talked a bit. Lucas was very excited for college and we were there to support him. The problem was, whenever I looked at my brother I always saw him like he’s sucking my boyfriend’s cock. I hoped that it would pass, because I don’t know how I could talk about this to anyone. Jack and Lucas wanted to get in the water but I was not in the mood, so I told them I was gonna read a book. They told me it’s fine and they went to the river. It was kinda shallow so I can see them standing in the water. I tried to forget what I saw and read the book but after a few minutes, it looks like I fell asleep. When I woke up, I couldn’t see neither Lucas nor Jack. I knew something was happening. I quietly went back to our tent and on the way I saw Lucas getting out of the tent. It looks like they fucked. I said “Hey” to Lucas and acted like I didn’t know about anything. He told me that he needs to pee and I said fine and went to the tent. The smell was there, I know they fucked. Jack was shocked but he already wore his clothes back. I told him that I was really horny and I needed to suck his cock. He told me that he is not in the mood but I didn’t care. I started kissing his neck and he got hard immediately. He told me that I need to deserve his cock and he raised his arms. He wasn’t wearing anything except for his shorts so when he raised his arms, I saw his hairy and sweaty armpits. I started sniffing his hairy armpits while playing with his cock over his shorts. I felt his cock directly, he wasn’t wearing any boxers. I raised my head to suck his cock but he pushed my face into his sweaty armpits and ordered me to lick. I started licking his armpits and started playing my cock too. Then when I was gonna suck his cock he told me to stop and asked what if Lucas comes back and I said him that I’ll only lick for a few minutes. Before he replies I took his shorts off and started sucking his hairy cock. I was right. Before I came, he came to my brother. The taste, the smell, I knew it all. I told him that his cock is really delicious and then we heard my brother. He was taking a video for his friend so we went outside too. We sat and talked a bit more and ate marshmallows. This trip was only for a day, so we went to sleep early because we wanted to wake up early and take a walk in nature. When we slept, my brother said that it was cold as we were really close to the river, and he wanted to sleep between us. I saw Jack smile and I immediately knew that they were gonna fuck tonight. So… I did what everyone would do, I accepted it. When we went to bed, I acted like I was sleeping like 10 minutes later. I heard a sound, it was the lube’s sound, and then Jack said “Are you ready?” and all I heard was a silent moan. I was facing my brother but I couldn’t open my face. After like a minute I saw Jack getting faster. I was really impressed, like, how can my lil’ “so called straight” bro could take my boyfriend's huge cock? I mean, even I have hard times getting used to it. I wonder how many times they’ve fucked today. I tried to take a peek by opening only one of my eyes and saw that my brother’s eyes were closed with pleasure and my boyfriend put his hands into my bro’s mouth. He was getting fucked while sucking my boyfriend’s fingers. I got so hard. While laying next to me, my boyfriend was destroying my brother’s hole. Lucas raised his legs so Jack could fuck him faster and easier. Lucas’ cock was hard too and he started to jerk off. Jack fucked Lucas for 10 minutes and all I can do was trying to take a peek with one eye open. When Jack was close he whispered that he was close so I started with playing with my own cock, hoping that they don’t see it under the spread. I opened my eyes one last time before cumming to my hand and saw that Jack was choking Lucas with each thrust, and Lucas was jerking off as fast as possible, it was clear that he liked it. Jack was using my brother like a sex toy. They both came at the same time, and Lucas’ cum even came to my face. I hope that he didn’t see it because I wanted to taste my brother’s cum. I came to my shorts and with one last peak, I saw my boyfriend taking the cum from Lucas’ destroyed asshole and made Lucas eat his cum. He sucked my boyfriend’s cum covered fingers. After a few minutes I saw Jack snoring so I turned my back and licked my brother’s cum - it was tasty.
In the morning, everything was “normal”. It looks like neither of them saw me jerking off to them. I woke up last, so I was pretty sure something happened again. When I brought the lube, I thought Jack & I were gonna fuck. I didn’t know that my boyfriend would fuck my brother. Anyway, we changed and decided to take a walk before returning home. When we were walking the two of them told me that they needed to piss, and I knew something was gonna happen again. And something happened again. I watched them go to the river again, but this time my brother bent over, and my boyfriend took his dick, put it inside my brother. I didn’t expect them to fuck as they don’t have much time, but Jack didn’t push his dick all the way. He only put the tip and his eyes were rolled with pleasure. I understood that he was pissing in my brother’s hole. After a few seconds my boyfriend slapped Lucas’ ass and Lucas squatted. He sucked Jack’s cock’s tip and started squirting the piss. When he was done, he got up and I went back to the road as fast as possible. We walked for an hour and decided to turn back.Jack, again handled the tent and we handled the cleaning. On the way home, I told them that I was tired and sat on the back. I laid and acted like I was sleeping again. Not much, a few minutes later I heard sucking noises. I opened my eyes and saw that Lucas was sucking Jack’s cock again. A few minutes later Jack moaned and cum. He panicked thinking that I would wake up but I acted like I didn’t hear it. When we arrived home, Jack woke me up by kissing. He told me had so much fun and hugged us, but I could swear that I saw him grabbing Lucas’ ass. After this trip, we haven’t made a new plan though. And lube? It was empty... We are really cool and thinking about moving together with Jack, but he still doesn’t know that I know he fucked my brother. Maybe I should get revenge by getting fucked by his best friend, who knows?
