My Brother Share Me With His Friend

I grew up in very rural part of the south that was really boring and kind of backwards. There was no one really around because it was so rural neighbors were spread out. I didn't have many friends, because i was a little chubby and awkward and even if i wasn't there just wasn't anyway to get around until you could drive.
At age 14 I started sucking my older brother and his best friend's cock just so I could hang out with them and they'd take me places because they could drive. They were about 17 I had just turned 14. It wasn't my brother idea but he also didn't stop it or seemed to have a problem receiving it from me which was awkward form me the first time. His best friend Dave was always around our place and pervy around me I (looking down my top, making inappropriate comments about my big boobs for my age) but he was super cute, and popular, and i had a total crush on him of course.
One day we were all in the basement alone, they where just playing video games and I wasn't wearing a bra hoping Dave would notice. He did, and started making his usual comments about how big and bouncy they were for 14. When out of not place he pulls me down on the couch between them and asks if a want to go into town with them later to see a movie.
"Hell yes!"
"Well, if we take, want are you doing for me?" Dave teased.
I froze. I was not dumb about sex but had done nothing not even kissed. I heard my brother laugh, like it was funny.
Dave just unblucked, pulled it out, and was like, "I know you like me, so suck it, to show us your cool to hang out with. If you make it worth it you can be in our click."
I have never seen a real in person cock in my life. I was terrified. "I don't know how, but i want to." I heard myself say to which my brother laughed at me and literally pushed my head down to his friends cock like it wasn't even a big deal.
"Open and learn you can use that mouth from more than food." Dave said pulling off my t-shirt leaving me big tits exposed to them both while he fondled them. I was blushing and in shock and honestly humiliated my bother was seeing this and laughing about it. My brother had never been anything but close with me i would never of expected this, but I was so crushing on Dave and wanted to please him i found myself with a mouth full of cock and my exposed tits swaying as Dave thrust in my mouth like i knew what I was doing but i didn't! It was all i could do to hold it open and be mouth fucked. It was all happening so fast. One minute we were all playing videos games and talking about the movies the next I was topless sucking dick in front of my brother. Dave kept saying "no teeth", "deeper bitch," " We know you like to eat, eat my hotdog chubby." I don't know why his mean words turned me on but i could tell my pussy and soaked. I felt my brother keep pushing the back of my head down on Dave's cock harder. I was gaging not able to keep up and suddenly Dave was yelling "swallow it you fat fucking bitch" and my mouth was flooded and I tried to swallow but i was gagging.
But the crazy part was as i came up from gagging my brothers dick was already out and in my face waiting, he didn't ask, he just kept putting it to my mouth waiting for me to open. I felt awkward as hell, i knew this was really wrong, and it was one thing to suck off an older guy to get him to like you, but my brother?! I just felt so awkward and didn't know what to do, so i opened my mouth and let him put it in and Dave was cheering him on saying "Hell yeah, we got our of group suck slut! I told you she would for me." My brother cam fast and I actually swallowed more this time. They we just so happy i did it, i was still in shock, but they was thrilled and just like that I was in, and one of them, they took me everywhere and including me in everything and I was there secret suck slut no one knew i did it.
It became normal and I got really good at sucking dick doing it all the time. My brother was totally normal with me otherwise. We didn't even talk about it, nothing changed between us but as soon as Dave came over, we'd all go down stairs and I'd suck both there dicks, topless of fully nude, while they played video games until they both had enough. I got to go everywhere, know the older kids, get popular, all no one knew what i did for it.
Eventually Dave took my virginity and started to fuck me while i sucked my brother and I honestly was all into it and loved being used like that as long as Dave brought condoms. Being spit roasted by older hot guys made me cum so hard. I just assumed that when the fucking started my brother would fuck me too. He didn't. No one said anything about that, but he didn't sometimes he'd finger me and a few times ate me out, he loved to make me cum but he never fucked me and until this day i have no idea why. Maybe that was his line.
It just stopped when they went to college and by then i had lost weight, was great at sex, and popular. My brother has never mentioned it since.
