Life Lesson

*Told from the perspective of Terry McGinnis, the Batman of the future.

I was stark naked, flat on my back, sprawled out on my bed. My hand was wrapped firmly around my cock, my huge cock, as my other hand ran through my black hair. My cock was huge, definitely the biggest in my school. I let out a quiet moan as my fingers danced up and down my 11 inches. I thought about Dana, hot ass Dana. I thought about the time we fucked in the janitors closet at school. I thought about the time she gave me head while I drove her to a family reunion. I thought about the time I fingered her during dinner with my mom.

"Terry?" a voice called as my bedroom door swung open.

"What the hell?!" I cried as I pulled a blanket up over myself, just barely.

"What are you doing?" my little brother Matt asked as he stepped into the room.

"Isn't it obvious?" I said, annoyed, motioning to my naked body and the bottle of lotion on my nightstand.

Matt shrugged.

"I'm trying to jerk off here!" I snapped, embarassed I even had to say it.

"What's that?" Matt asked quickly.

I paused, my eyebrows raised.

"Wait...you're 14 and don't know how to jerk off?" I asked.

"No," Matt said, ashamed. "I hear guys at my school talking about it a lot, but I don't know what it is."

"Wow," I sighed. 

I've been jacking it since I was like 9. I figured I'd be a cool older brother, and teach him how to rock his own world.

"Alright, I'm gonna teach you a good life lesson," I said, sitting up slightly. "Pull up that chair."

Matt grabbed the chair by my desk and brought it next to my bed and sat down. Without hesitation, I pulled the blanket off of me, displaying my penis for my brother to see. 

"Whoa," he said, closing his eyes.

"Oh come on," I said, grabbing it.

"It's so big," he said, looking at it.

"I know," I sneered. "Now take off your shirt."

Matt frowned for a minute, and took off his green t shirt.

"And your pants."

He paused yet again, before shimmying out of his black jeans, revealing blue boxers.

"And your boxers."

He froze.

"Come on," I encouraged. "We're all guys here."

I swung mine back and forth. Matt finally took of his boxers, revealing a nice dick.

"Wow Matt," I said. "You're big for 14."

His cock was already a little hard, obviously stimulated by its current situation. 

"Is that bad?" he yelped.

"Hell no," I laughed. "The bigger the better. Us McGinnis men have nice big cocks. I guess we can thank dad for that."

I stroked mine and smiled.

"Now sit down," I said as I smeared a glob of lotion over my huge head. "And put this all over your dick."

I tossed him the lotion, and he rubbed some over his young dick, which was almost rock hard.

"Now, the fun part," I said, smiling at him.

I started slowly, moving my hand up and down my shaft. Damn, it felt good. My thumb massaged my head.

"You too," I said.

Matt started to rub his dick. He stayed silent as he did it, but his face turned red and he went faster and faster. 

"Feels good doesn't it?" I asked.

"Yeah," he laughed.

"Now, since this is your first time, you might not cum a lot," I explained.

"What's cum?" he asked.

"Give me another minute and I'll show you," I said.

We sat together and jerked our cocks, our big McGinnis cocks. Finally, Matt started panting as the smallest bit of liquid dripped from his dick.

"That's okay," I said. "It'll get more normal soon enough."

"I bet yours is normal," he sighed, embarassed again.

I smiled. I was jerking harder and harder. My toes curled. My jaw clenched. My hand glided up and down my lubed up cock. 

"Fuck, I'm about to cum," I groaned.

Matt sat up, staring at my massive dick. I let out a loud moan as I came. White rockets of semen erupted from my dick, shooting up into the air and splattering across my washboard abs. I panted, continuing to jack and stroke after the last of my juice was done flowing. 

"Whoa, that was a lot," Matt said. 

"I know, and Dana takes it like a champ," I laughed, slowly stopping.

"What?" Matt asked.

"Lesson for another day," I said with a laugh. "Now pick up that shirt by your foot."

Matt reached down and picked up a green Hamilton High t shirt, stained with cumshots of days past.

"Clean yourself up with it," I said, running my hands through my hair.

Matt sloppily wiped his cock with the shirt.

"Toss it," I said, reaching out.

He threw the wet shirt and me. I wiped off my cock with it, then my stomach. 

"That felt really good," he said to me.

"Fuck yeah it does," I said. "You can do it whenever you want, as long as you're alone or with me."

"Okay," Matt said. "This is awesome."

I laughed. 

"Now get outta here. When you cum as much as I do, you need a nap when you're done," I said as I spread out, still naked and sticky.

"Thanks Terry, you're the best brother ever," he said, quickly getting dressed again.

"See ya, buddy!" I said as he exited my room.

My cock softened and rested against my thigh, still at least nine inches long. 

"I am the best brother ever," I said to myself, closing my eyes and drifting off to sleep.
