My 16-year-old big brother Ross had his girlfriend over. Our parents weren’t home, so he told me not to come into the room we shared until he told me it was okay. When I left I didn’t close the door all the way. I waited outside until I heard some moaning and carefully opened the door just enough so I could see.

Anne was on her hands and knees, and Ross was behind her. They were both naked, and I could see Ross was humping her behind. She was moaning a lot and saying things like “Yeah, fuck me! Give me that big dick!” I could see his muscular football player body. His butt muscles were flexed as he pounded her. I felt my penis get hard, and I rubbed it slowly while I watched them have sex.

After a while he said “Fuck!” and stopped moving. Shortly after that he pulled out, and they collapsed onto the bed. I could hear them kissing. I carefully crept down the hallway. 

When she finally left, I heard him get into the shower. I was waiting on my bed when he came out wearing a towel. “Fuck, I’m exhausted,” he said as he lay down. I went back to playing my Nintendo. A little while later, I could tell he had fallen asleep.

I was very curious about his dick. I rarely got much more than a quick glimpse. I carefully moved the towel opening until I could see his groin. The light blonde (he called it dirty blonde) hairs were the first thing I noticed. Then I saw his dick which did look big. It was resting on his large balls that had some fuzz of the same color. I really wanted to touch it, but I was afraid he would wake up. I covered him back up and went back to playing my game.

Every so often I kept peeking at his muscular body. He had a nice chest with 6-pack abs. His hands were beneath his head, so I could see the dirty blonde hair of his armpit, too. I’m 10 and don’t have any hair on my groin, balls, or pits. Maybe that’s why I was so fascinated by his body.

He woke up about an hour later and got dressed, but I found I couldn’t stop thinking about him, his body, and him fucking Anne.

Two nights later, I was lying in bed awake. I pretended to be asleep when he came into the room. He got into bed and within a few minutes I could hear his hand moving against the sheets. I knew what he was doing. I thought this might be the time to do what I had been thinking of for the past couple of days. “Are you jacking off?” I asked.

“What’s it to you?”

I swallowed hard. “Because if it’s hard, I want you to do to me what you were doing to Anne.”

He was silent for longer than I liked. “And what was I doing to her?”

“You were humping her butt. I watched you guys.”

“I wasn’t . . . wait, you want me to fuck you in the ass?”

“Yeah. She sounded like she really liked it. I want to feel that good.” I took off my pajama bottoms and briefs to be ready.

“You’re fucking serious.”

“Look!” I said. I took a flashlight, lifted up my sheets, and shone the light on my naked body.

He waited for a moment, and my heart started beating faster when I saw him pull back his covers. He got out of bed, and I could see his dick sticking out of his boxers. It was hard and big. He walked over to my bed. I kept the light on his groin. “This is what you want?” he asked.

I had heard him talk a lot about blowjobs before, and I knew he liked them. So I decided to show him I was serious. I sat up, nodded my head, and leaned forward and put his dick in my mouth.

“Okay, Brett. Pull my boxers down.” I let go of his dick and pulled his underwear down. I put the light back on his body and watched him grab a bottle and squirt some stuff onto his dick. The liquid glistened in the light as he rubbed it up and down the thick shaft. “Assume the position.”

I put the light down and got on my hands and knees. I was so excited! Ross got behind me on the bed, and I felt him rub some of that stuff on my hole. His finger went in a little way, too. I smiled as I felt his dick move into my crack.

“Fuck me, Ross!” I said like Anne had.

I felt his cock push into my ass, and it hurt right away. How could she be so excited about this? I wondered.  

“Dude, you’re way tighter than a chick!”

“Is that good or bad?” I asked biting off the pain.

“That’s so fucking good!”

His fingers dug into my hips, and I felt him pushing his dick into me a little faster. I made a couple of loud sounds, and he shoved my face into my pillow. “Shhh! If Mom and Dad see us like this, they’ll fucking kill me!” When I nodded my head I understood, he returned his grip to my hips.

“Now I get why the fags like this so much.”

Soon he has humping me slowly. It started hurting less as he fucked me, and I was glad about that. He kept going deeper, though, and I started to wonder if I would be able to handle the whole thing. The way he was breathing and moving, though, I didn’t think I’d get a choice.

He kept pushing it into me and humping, and soon I could feel him pressed against me. He started pumping faster. I could hear a little bit of slapping noise, and I thought I could feel his balls bounce against me at least a couple of times.

It started to feel good, and I began to understand why Anne liked this so much. As he started to go faster, I got brave and said, “Fuck me, Ross! Give me that cock!” but not too loudly.

I felt his hands slide up my smooth body, and they gripped my shoulders. He pulled his dick backward pretty far and slammed it back in. I moaned loudly. “Dude! Fucking hell!” he said. He stopped fucking me, and I could feel him moving. “Open your mouth,” he said. When I did, he stuffed something into my mouth. I’m guessing it was his boxers. Then he went back to pounding me hard. 

Since I couldn’t make as much noise, I went ahead and moaned more as he pounded me. After a while, he leaned over my back. I felt his breath on my face. “You like that big cock, don’t you?” I gave a muffled response as I nodded my head up and down a lot. “And you’re going to let me fuck you again, aren’t you?” I nodded my head even more this time. I wanted it! “You’re gonna suck my fat cock, too?” I nodded. He smacked me on the ass. “Damn right you are, little bro.”
He straightened his body and started pounding me even harder. My body was rocking so much, my elbows buckled. My face landed in my pillow. I felt his hand move to my upper back and press down while he banged me hard and deep.

He started going faster and grunting before suddenly stopping. His dick twitched like crazy in my butt, and I felt something warm inside. After the first few twitches, he went back to slowly humping me, and his cock kept jerking around in me. Again he leaned down. He pulled his boxers out of my mouth. “That was fucking awesome, Brett! For once, I’m glad you were spying on me.” He smacked me on the ass before pulling out of me and returning to his bed. “Thanks again, bro. That was fucking incredible.”

“Good night,” I said cheerfully.

In the morning, the smell of food cooking woke us both up. He stretched and yawned. “Good morning,” I said.

He smiled. “Yes, it’s a good fucking morning for sure.” He threw back the covers and got up from bed. His dick was hard.

“Can I. . . I want to really get a good look at you naked.”

He gave me a smile that warmed me all the way through. He came over to my bed. “Look as much as you like. You’ve earned it.”

I let my eyes scan his whole body and take in every sight, especially his big dick. As I looked over him, I felt his fingers on my chin. His thumb went over my lips. “While I’m standing here hard like this, how about you give me a quick blow?”

I opened my mouth and went down on him a little and began sucking. 

“You can get  more than that in your mouth. The more of my dick in there the better. Go on,” he said. As I continued to sucking, this time taking more his dick into my mouth, he leaned over and turned on some music. “Suck that cock, bro.”

I surprisingly found I liked this. It tasted a little salty, and it was fun feeling his hardness move inside my mouth and against my tongue. After a bit, he put his hand on my head and started guiding it faster. When he grabbed some of my hair, it felt like a fire ignited in me. All I wanted was his dick filling me. I grabbed a hold of his firm butt cheeks and started sucking him faster.

“Yes! That’s it!” He took both of his hands and grabbed my head. He was moving it back and forth at the same time as he used his hips to shove his cock deeper into my throat. He ignored my gagging, so I just tried to deal with it. I quickly wiped the tears streaming down my face caused by my choking. “Later I want a long, slow blowjob, but for now we gotta make it quick.” 

He picked up speed. I just focused on opening my mouth wide and trying to breathe. I learned if I held my breath when his dick went deep it was easier. I would breathe in when he pulled back.

“Suck that fucking cock, man! You want every goddamn inch!” he said. His balls were lightly slapping me in the chin, and I watched his tummy muscles flexing as he fucked my throat.

After several moments, I heard him say “Fuck!” kind of loud. He shoved his dick deep into my throat, and immediately I started choking as stuff sprayed out of his dick. “Swallow that cum!” he said through gritted teeth. I swallowed the fluid as it rushed out of his cock. “Fucking hell!” 

When his dick stopped twitching as much, he pulled it back so it was in my mouth but not down my throat. That’s when I could taste his salty liquid. He let me suck some more before it out of my mouth. “Suck on my balls,” he ordered.  With his sac in my mouth, I watched him squeeze his dick. Some white stuff came out of it. He rubbed it on one of his nipples. He did it again and drew a line going from his belly up his chest.

He had me stand up. “See my cum? Run your tongue up that line and make sure to lick all of it off. When you get to my nipple, you’re going to suck the jizz off it.”

I did as he said, running my tongue over the salty line he had drawn. He hit his bottom lip as he watched me follow the trail to his nipple. Then I sucked his nipple until I couldn’t taste anymore of his jizz. “Fucking hot,” he said. “Did you like it?”

“Yeah. What is it?”

“Your dick makes it when you’re a teenager. When you suck my dick, always make sure to swallow. When a bitch doesn’t swallow, it doesn’t feel as good. You gotta keep swallowing that shit and keep on sucking when your man is coming. Got it?” I nodded my head. “Good boy.”

We got dressed in silence. He finished before me and left the room as soon as he was done.

We ate breakfast with our parents. After we helped clean up, I went downstairs to play video games. He stayed upstairs. A couple of hours later, he came practically running down the stairs. “Stand up!”

I was scared something was the matter, so I paused my game and hopped up. He grabbed me, spun me around, and shoved me onto the couch. “What are you doing?” I asked. He grabbed my shorts and briefs and yanked them down in a single rough tug before pulling them all the way off.

“Mom and Dad just left for the store. I’m going to fuck your little ass.”
I turned my head and watched as he quickly pulled off his shorts and boxers. He was naked except a pair of white ankle socks. I loved seeing his naked body, and I didn’t exactly know why. He stroked on his dick a few times quickly. “Spread your legs!”

I spread them just as he joined me on the couch. He quickly got his dick into my crack, and I felt him shoving his meat into my hole. He pushed his dick in a little faster than last night. I took a bite of the throw pillow as he roughly entered me. He pushed my T-shirt up and over my head so that it covered me. I felt his strong arms wrap around my chest, and he began fucking me. I knew he wasn’t in all the way, but it didn’t matter.

“Your ass makes me fucking crazy!” 

I partly moaned and partly yelped as he shoved his dick in all the way. 

“That’s right, bitch. Make some fucking noise! No one’s around to hear you beg for it now.”

“Fuck me!” I said, but not like last night. It still hurt too much for me to be honest right now.

He ripped my shirt off my body, grabbed my hair and pulled it backward. “You want that big cock, Brett?”

“Yes!” I cried out.

“Whose ass is this?” he asked.

“Mine!”

He smacked me hard on the butt. “Whose is it?”

“Yours!” I corrected.

“That’s right, bitch. It’s my fucking ass, and I get it whenever I want it, right?”

“Yes!” Okay it hurt a little, but now I was totally turned on. “Give me your fat cock, Ross! Oh gawd!”

He was pounding me hard now. It almost felt like he was bouncing off me and landing back on top. His dick thrust so deep. My ass hurt and begged for his cock at the same time. After doing this for a while, though, he stopped. His dick was plunged deep. He made small movements so that his dick moved inside of me.

After a while he sped up just a little so that he was slowly humping my ass, making long pulls backward and slowly refilling my ass with his meat. I reached back and gripped his butt cheek. “I want my dick in you all the time, bro.”

“I love your dick, Ross. I want it bad.”

He surprised me by kissing my shoulder and neck softly.

“Want to know a secret?” he asked. I nodded my head. “You’re a way better fuck than Anne.”

That almost put tears in my eyes. Now I wanted to please him even more. “I want your big dick, Ross. I can’t get enough. I love you.”

He relaxed his body against mine as he slowly fucked me. “I always hated sharing a room until now.”

“I’ll make your dick happy. I promise! I’ll suck it, or you can put it in my butt whenever you want! I’m all yours.”

“You’re fucking right you are,” he said.

After several moments he pulled out of me. He sat down and motioned for me. I moved over to where he was. “You want me to suck it now?”

“Fuck no! I want that tight ass! But you’re going to sit on it now.” I got in his lap with my back toward him. He guided me, holding onto his cock, until I was sitting on his dick. I started slowly sinking onto it, but as it filled my hole, I just relaxed so that more of my weight was free. It started climbing up my ass quicker. He kissed my back, and I decided to just relax completely and sit down all the way. I moaned loudly as the thick shaft buried itself in my ass.

I could feel his hips moving his dick inside me. I lay against his muscular chest with a big smile on my face. His fingers dug into my thighs. I reached backward and hugged his neck. I looked into his blue eyes and couldn’t help but smile.

“You’re all mine, little bro,” he said softly, his lips close to mine. I could smell his breath. I opened my mouth a little to breathe in his scent more, and his lips covered mine before his tongue slowly pushed into my mouth. We kissed greedily as his dick slowly moved inside my ass. I moaned as we kissed. I moaned a little more when I felt his fingers rubbing my nipples.

When he stopped kissing me, I said, “I love you, Ross.”

He covered my mouth with his again, and as we kissed his hand slid down my chest, then my tummy, and into my groin. His fingers rubbed my wood. I kissed him more eagerly as he worked my dick. Soon I started using my legs to raise and lower myself on his wonderful cock. “Fuck me hard, Ross. I want it so bad!”

“Get on your knees on the floor,” he said.

I got off his deck and knelt on the floor. He bent me over the couch. He shoved his dick in me and started pounding me again.

“Yes! Oh yes, Ross! Give it to me!”

I felt him moving behind me, and I glanced behind to see that he was raising himself up on his feet. He drove his cock into me even harder now with deep thrusts that made me feel like his dick was in my chest. His hands gripped the back of the couch as he plowed into me. I made loud moaning sounds which seemed to keep him going strong.

After fucking me like this for a while, he pulled out again. He pulled me back so that I landed on the floor. He grabbed my legs and shoved them so that my knees were in my chest. He moved them even farther toward my head so that my ass was pointing straight into the air. I watched his dick sink into my hole. He drove his thick cock deep and hard as I panted.

Soon his tongue was back in my mouth as his balls bounced against my butt with each thrust. He pounded my hole hard for several minutes before he came. He kissed me with his fat meat buried in my tight hole, his dick twitching as it unloaded.

When he was done, he looked into my eyes again, smiling. That smile would make me do anything, I knew. He pulled out of me and sat on the floor, his back against the couch.

“Ross? Can we. . . could we cuddle?”

He lifted his arm up, and I moved over to him. 

“Let’s lay down,” I said.

He moved himself onto the couch and lay down on his side. I joined him and lay next to his hot body. I let my hand roam over his muscles and my fingers play with the blonde bush above his dick. When I looked up at him, he kissed me softly. I opened my mouth again, and our tongues moved slowly as we explored each other’s mouth.

When we stopped kissing, I put my head next to his chest. “Can we cuddle like this in bed tonight?”

He began playing with my hair. “Sure, little man. We can do that.”

He fell asleep, and I just lay there watching him, listening to the music of his breathing. I had never felt so deeply for him before. I wondered if this was what that kind of love was like. Not between brothers, but, more like what he might have with Anne. Then I heard a car pulling up. I woke him up, and we immediately got dressed.

Later at night after dinner, we were downstairs watching TV while Mom and Dad had some friends over for drinks. He was sitting on the couch, and I was leaning against him. I reached up and kissed his cheek. He moved his face toward mine, and I felt his hand on my chin. He lifted my head up, and we kissed slowly with our tongues. 

After we had kissed, I asked him to take his shirt off so I could enjoy his body. He smiled and removed his shirt. Once again, I let my fingers slide over his bare chest and tight stomach. I stared at his nipples. I moved my mouth to the one closest to me and began sucking on it.

“Mmmm,” he said.

I continued sucking and let my hand wander further down his body. Finally, I slid my hand into his shorts and boxers. I played with his dick while I kissed his chest and sucked on his nipple. As his dick stiffened, I returned to his lips, and we kissed. I got on my knees so that I could reach his other nipple.

Now his dick was rock hard, and I felt him shove his clothing down. I moved my hand to his large balls and gently massaged them. “Ross, do you love me?” I asked, staring into his deep blue eyes.

“Very much,” he said. We went back to kissing, and I felt his hand slide down my back over my shirt. Then it sank into my shorts and underwear. He gently squeezed my butt cheeks as we kissed.

“I love you, too,” I said before using my tongue to draw a line from his chest to the bush of hair. As I went down on his delicious cock, I felt him push my clothes down. His fingers found my dick and slowly rubbed me. When he tried spreading his legs wider, I reached down and shoved his shorts and underwear farther. With his legs open more, I could suck on his balls. “This time I’m going to take my time,” I said.

“Fuck yeah,” he said. I was going to make love to his dick with my mouth nice and slow. And I hoped like hell he would fuck me when we got into our room.
