Teenagers these days are getting out of hand. They always think they know everything. 
This young stallion was given the Internet too early, and two seconds later he's choking on some old man's fat cock in an alleyway after a pride parade, the boy covered in glitter, rainbows and all. The older male then pulls out of the boy's mouth, leaving his soft lips with a needy groan, painting a fat, chunky load all over the brat's smiling face. That was his geography teacher. The youth chose to suck him off all the same... what gay man wouldn't deny a man in need? Especially if they are handsome, and smartly dressed with a bulge.
After this young horse showed his older, pervert brother one of his FurryTok twerks, the older jock got extremely turned on.
He let his brother twerk his soft ass against his hard, erect bulge clearly visible down the side of his shorts, and not even some flimsy shorts could hope to contain the massive meat that the 18-year-old stud-of-a-jock brother contains. There's only just a three-year difference between the two brothers, but they look like night and day. The jock-type stud is already starting to grow some rough stubble and a nice growth of pubes and natural fuzz at the base of his cock, whereas the FurryToker has yet to grow his first facial hair.
Add to that, the older brother's extremely deep, manly voice, and you'd mistake him for being a father. You'd easily mistake his younger counterpart for being a girl if you could hear him, as well!
The jock's horsecock flared against the side of his veiny, meaty leg as dance music played in the background. Veins tensed in his neck as he took in the scene before him.
"My stupid-ass fucking faggot brother is throwing his ass back like it’s nothing..." he whispered out, hungrily licking his lips.
Everytime he felt his younger brother's ass against his shorts, his cock head flared up, leaking a clear stream of precum onto the ground.
His big hands encircled around his brother's smaller, lithe hips, directing the kid to the part where he really wants his brother to twerk: on his cock.
The jock whined out in pleasure, throwing his head back.
"Oh fuck yeah baby, bounce on my dick..." he said in a very deep, lustful voice, surprising the young lad.
--After the dance...
The situation only became more heated after the young horse had exhausted himself from teasing his brother. The older jock looks like he's about to blow a fucking load all over himself after all of that twerking. His cock is desperately itching for attention and throbbing on its own, the puddle of precum forming on the floor is now at least one inch deep, and he looks like he's just coming down from a high.
So he decided to play a game of League of Legends to distract himself.
His younger brother is still horny, though. He's only just started, and wants to keep experimenting with his older brother.
("I can't believe I have to end my match early for this...") 
The horse sighed, set down his game controller, and gave the youth a warm smile.
"Wanna see something else, big bro?" The teenager said in his sweet voice, seductively pulling down his brother's shorts without consent. No consent needed, anyway. The perv wants this bad.

His brother's massive horsecock came flinging out of his musky shorts, straight in front of his amazed, cute little face.
"Whoa, its big!" The youth exclaimed.
The jock brother was starting to gain some consciousness again.
"Yeah... I know..." he lovingly stroked his brother's head of hair, directing his mouth around his flared-up tip.
The little brat took his big brother's fat, hairy horsecock in his mouth without a second thought, bobbing his head up and down the cock like an experienced whore. 
"Whoa kid, what are you doing- Mmm, fuck yeah..." Not like big brother here is complaining, interrupting his gaming session only to get some free head from his 15-year-old brother.
"Damn kid, that mouth feels hella good..."
Big bro groans out and struggles to keep his eyes open in pleasure as he watches his fat horsecock disappear down his bro's young throat.
"Fuuuuck, where'd 'ya learn that..."
Little bro handed him his phone mid-blowjob and big bro opened it up to a webpage about "how to give the best head".
Curiosity compelled him, and the brother moved onto another tab, full of stories which described blowjobs in detail.
The next tab over was of FurryTok - finding it all to be videos of his young brother twerking. His pervy mind was going apeshit at this point, either he's been too long without a lay, the heat is getting to him, or maybe it's the ultimate taboo that's turning him on, but he can't deny:
"Yeah... my little brother has some cake."
That didn't stop him from busting a fat nut inside his mouth, probably the fattest and most chunkiest nut he's blown in a long time, feeding the kid enough protein to last him until he's 18.
The boy popped off the cock with streaks of cum getting plastered all over his face, his brother's fat horsecock still orgasming from the tightness of his teen throat, and brought his face down to sniff at his hairy musky nuts.
"Mmmm, you smell so fucking good..."
"Stupid fucking twerker," big bro groaned out, slapping his younger sibling's fat bubble butt.
"Keep throwing that ass around and you'll attract the wrong type of men."
"Men like you?" The brother replied back with a smirk, licking his lips of 18-year-old perv-loving spunk. His horsecock throbbed again.
"Ngh. No. Men that will rape you. You won't want that."
Younger bro looked deep into his older brother's eyes.
"Maybe you should rape my throat instead... So nobody else can do it." He offered.
A few seconds passed as the older brother was taking stock of the situation, then grabbed his hardening cock, ready to bust another load in his slutty brother.
"Not a bad idea, you know..."
