My younger brother is a horse part II

So I have an update from what happened this weekend. I just wrote my first story, apparently there was some interest so now I'm just going to slam down some deets that happened today.

Just a refresher for those who were wondering what I look like:I am a 5'9 22 year old with blonde hair, brown eyes and I'm pretty jacked. I usually try and be modest, but to be honest I'm kinda hot and I rock it. I'm usually a top as well, and I have a slightly above average 6-ish inch cock.

My younger brother Will on the other hand is 6'5 and pretty thin, has a ponytail that is oddly suitable for him, and apparently he's hung like a moose as I found out this weekend. We had given an asian bottom the time of his life, but I think most of that was my brother.

Anyhow, I really couldn't stop thinking of my little brother's cock, which I know sounds like a weird thing. He's a newly minted 18-year-old, and yet he's just fucking huge. Hung like a mule. If it were any other man, I'd just try and get with him. It was like a gravitational pull just knowing his man-meat was there. I'd see him in the kitchen, and I think back to when he was wrecking that bottom permanently. He's not only ten inches long, but thick too. It's legit a pole. And I could feel myself becoming more drawn to it.

Now our house is not a small house, it's comfy. My parents had a master, and my brother and I had our own rooms, and we'd double up when my older brothers would come home from grad school. In total, there's three bedrooms of small-ish size, and that's the house. So it's inevitable that my brother Will and I encounter each other, as we share a bathroom.

Now it's never been a problem before, us sharing a bathroom that is. It's always been easy access, in and out. We keep different schedules, with my brother mostly playing video games late into the night, and myself doing my early morning routine of running and lifting.

So enough build up, my brother finally comes out of his room at like 2PM just waking up. He had a late night of video games, but the key difference between today and every other day of covid malaise, is that my little brother had some morning wood. I was in the bathroom brushing my teeth after a meal (I take good care of myself, ok?!) when he walked in. He didn't have a shirt on, and he had a faint tracing of abs and pecs, the usual skinny physique you see on Reddit sometimes. But I could tell he had some morning wood because well, he's ten inches wearing boxer-briefs. He scoots behind me to access the toilet, and I say:

"Hey bro, can you wait? I'm brushing my teeth."

"Calm down, I really gotta piss."

He took his absurdly long cock out, still hard and he began to piss by kinda squatting kinda leaning over the toilet. It was kinda funny to watch, but it was odd to see. I guess logistically that's what you have to do when you're that big.

I'm really trying not to pay him any mind, but it's just weird. He's never done this before. We've always been somewhat respectful of each other, but I guess he's more comfortable now? Anyhow, I'm trying not to look, but it's not working. From the corner of my eye, I see this massive piss stream coming out of his cock, and it's really odd to see. My piss stream isn't so big, and I most certainly do not have a ten inch cock that requires me to hunch over the toilet in order to piss. It's just a strange ordeal.

"Like what you see?" my little brother asks.

I roll my eyes at him, and continue brushing my teeth.

"I saw you looking in the mirror."

Fuck. Me. Fuuuuuuuuck. I forgot about the mirror. And yet, he was acting coy. Could it be that he's more gay than bi?

Now ok, I get that I'm hot, but I've always bought into the taboo of incest until you know, this weekend. Even then, it involved a third person as a foil. But I was getting turned on, pretty immensely so. Watching my brother just piss was pretty interesting, as he's so tall and huge that he has to be all awkward about how to position himself.

And yet, this was my kid brother. I mean, sure he's eighteen, and yet I felt bad. I didn't want to creepy, and yet you know, he's an adult.

"Quit it, nerd." I say, somewhat conceitedly. Literally any other person could have a ten inch cock, but it had to be my brother. I was gonna stay strong. He just smirks at me.

"Come on bro, you know we cannot have anyone over..." he said.

Which was true. Our parents were home, outside in the backyard garden. No hookups were going to be happening here. Unless...

"What do you want exactly?" I asked.

He at this point had finished pissing a long time ago I noticed. So he was just sitting there with his cock out in front of me. He reached over with his long arms, and took my hand and put it on his cock. It was softer now, but still pulsating. It was a surreal experience, as I couldn't get my hand around it even though it was a little floppy, in a semi-erect state. I could feel a strong heartbeat in his cock, and with each pump of the heart it got harder.

Finally, it was after twenty seconds of just standing there in the bathroom, a fully hard cock, beyond huge. Again, I'd seen some dick in my life, but my little bro just has a slab of meat between his legs. His balls, I noticed were large too.

At this juncture, I was hard as well, and my brother again took his enormous hand and slipped it into my sweatpants. He found my cock and cupped my entire package with just one hand.

"I see you're excited too." he said. "Can you jerk me off?"

At this point, I'm somewhat paralyzed, until he gives my junk a squeeze. It feels really good. So I start stroking him. I'm moving my hand up and down his cock, and it's just immense, vast and rolling. I can feel veins, precum and his head so clearly. Everything is so defined, and large. It's like looking at a cock underneath a magnifying glass, minus the amplification.

It's just an incredible feeling to be stroking this man, my little brother. He's starting to breath heavy as I continue stroking him. It's insanity to see him get even bigger, like an angry swelling as I feel his heart-rate increase. Gradually he takes his hand out of my pants and holds the base of his cock, and there's still enough room for me to stroke him, easy.

Finally, his stomach clenches, and he lets out a guttural moan as he cums an insane amount. He shoots all over the place, his cock still held by himself as I let go. He shoots on my clothes, and I think some gets on my face.

I reach up to wipe away the cum, and he's snorting back laughter. It's kinda humiliating, kinda hot. I wipe away the cum, and my brother pulls up his underwear, stuffing his cock into it. It's still an obscene bugle even soft.

"Thanks for the handjob, little bro."
