I had just shut off the TV after the college football game I was watching had come to an end, when I looked at the clock and realized that it was getting late. Both of my parents and my three younger brothers were already in bed, and I had to get up to work in the morning. I was currently taking a semester off from college and living at home while I worked down at the local supermarket to accumulate some money. Considering that I had to be at work by 8 AM, which was just seven hours away, I should have gone upstairs right there. However, I was feeling horny as hell and needed to get off. I opened up my laptop computer and went to my favorite porn website, where I quickly acquired a raging hard on from the movies I was watching. I pulled out my seven inch cock and began to stroke it as my eyes remained fixated on the scene of a young teen girl getting pounded in the ass by a massive dick. As the scene progressed, I became unsure if I would rather be the guy doing the fucking or the girl getting railed in the ass. Something about pleasing a big, horny cock and causing it to erupt because of what I had done just seemed to turn me on.
I had recently come to grips with the fact that I was bi-sexual. If I was given a choice, I would almost always choose to have sex with a girl as opposed to a guy, but I would sometimes get these urges to take another man's penis. I had never had much luck with the ladies, as for I did not spend much time around them. I went to an all boys' high school, and did not spend much time out of my house when I was not at school. I had spent so much time around guys that I guess they had just started to rub off on me.
Now back to the story at hand. I was beating my cock when I heard footsteps coming down the backstairs. I figured that it was my brother Matt, who was 18 years old. Although he was three years younger than me, he was a couple inches taller at 6'4". He had short, dirty blond hair, tan skin, and a thin, muscular upper body which he had shaped from working out. He had more success with women than I did, although I still had fantasized about having sex with him before. Just in case he decided to come into the living room, I quickly slid my dick back into my pants. However, this action did not do much to hide my erection, as a huge bulge was still visible through the pant material.
Since I really did not think he would come into the family room, I kept the porn movie playing. However, he did open the door, stuck his head in, and asked what I was doing. I frantically raced to hit the mute button on my computer. "N-n-nothing. Just...nothing," I stuttered nervously. He walked over to me, noticed the bulge in my pants, and then looked at the screen.
"Looking at porn, are we now," he said.
"Hey, everybody does it. I just gotta get off, you know," I replied.
Now things took an unexpected turn. Matt went on to say "Yeah, I know... and I would be willing to help you." As I turned towards him and gave him a very curious look, he said, "Well since you always get alcohol for my friends and me, and are always driving us around since none of us have cars, I really owe you a nice thank you. And to tell you the truth, I just had some of that vodka you got for me last weekend and I am feeling kind of horny."
Almost in a state of shock, I asked "Well, what did you have in mind?"
"Well, you can keep watching what you were watching, and I can maybe suck on your dick a little.
"You're really willing to give me head?" I asked.
"Yeah, I mean, if you want it," he stuttered as he got down on his knees next to the couch.
"You don't need to ask me twice," I responded as I hurriedly leaned back on the couch, put my legs up, and re-released my raging boner. I reached over to the laptop, which was positioned on a nearby chair, and turned the movie back on. I held my cock until my brother took hold of it, and he starred at it nervously as he leaned in. As I looked down at him, he plopped the head into his mouth and pressed it up against the inside of his cheek. I let out a loud moan of pleasure as he started bobbing his head up and down on my fat penis. His warm tongue quickly covered my dick with his saliva, as he tried to take my seven inch cock deeper and deeper into his mouth. I stared in a state of disbelief, as even though I was seeing it with my own eyes I could almost not comprehend that my younger brother had my cock in his mouth. I could not believe this taboo act was actually happening, but I was enjoying every second of it.
As he started to get a feel for it, as I'm guessing this was the first dick he had ever sucked, I turned my head back towards the computer screen and continued to watch the hot blond teen take a beefy cock up her ass. As I continued looking at the porn, my brother wrapped his hand around the base of my shaft, wrapped his lips right around the head, and started sucking really hard. He took his head off for a few seconds, feverishly jerked my meat, and then started sucking on my head again. He repeated the process a couple more times, and then started passionately licking the end of my cock. Even if this was his first time, he sure was enthusiastic! He wrapped his lips around it and continued to lick, swirling his entire head around while his hand churned at the base of my rod. I did not know how much longer I could last, as it felt like I was going to cum at any moment.
I began pushing my hips up in the air, forcing my penis deeper into his mouth. As I slowly pushed my dick up, he tried his best to engulf the entire thing. During his first attempt, he managed to take about half of it. However, after a few more tries he was making three quarters of my shaft disappear into his throat before he would start to gag and then pull his head off.
After I felt my cock head get squeezed by his gagging throat on several successive occasions, I knew that I could not hold it in any longer. I put my hand on the back of his head and started pumping my meat into his mouth. He kept his head in place and sloppily licked and sucked on my rod as it went back and forth between his lips. I finally let loose, thrusting my hips upward one last time and sent shot after shot my sticky cum into my own brother's warm mouth. With my hand still on the back of his head, Matt continued to lick around my penis, working to suck out every last drop of my seed.
With my mouth wide open and my eyes shut in a state of euphoric pleasure, I tried my best not to scream out in pleasure as I unloaded the contents of my balls into my brother's mouth.
Once I had started to come down and with cum dripping from his mouth, Matt let my cock flop out of his mouth and gave it one more long, passionate lick from base to tip before getting off his knees and walking towards the door. As he was about to turn and leave, I asked, "Where are going?"
"I'm going up to bed now," he replied.
I rolled off the couch and got down on my knees in front of him and said, "I still have to return the favor."
A smile came across his face as I started to unzip his tight blue jeans. I brought them down around his ankles, and they were soon followed by his boxers. His penis flopped out towards my face, and needless to say it was already hard as a rock. I had never seen my brother with an erection before, and I was surprised at how well-endowed he was. Even though he was three years younger than me, his dick was already longer and a little wider than mine. Unlike him, this was not my first rodeo, and I already could not wait to take it all of his tasty meat down my throat.
I slowly started stroking it with one hand as I lustfully admired its beauty. What I was about to do felt so dirty, but so right at the same time. I quickly snapped out of my trance and got ready to take my brother's huge cock in my mouth. I leaned forward and engulfed his head, tightly wrapping my lips around his bulging cock. As I began to suck, he instantly let out a loud moan and thrust his hips forward, feeding me more of his penis. My mouth willingly accepted his manhood, and I started bobbing my head back and forth on his dick while I worked my tongue along its underside. I proceeded to wrap my moist lips back around his bulging head and moved my face from side to side as I passionately licked all around the end of his penis.
