Best Little Brother Rex padded up the driveway, yawning as he adjusted the shoulder strap on his backpack. It had been another long boring day of high school and he just wanted to come home. Heading in the front door, which he found unlocked as per usual, his ears perked as he heard the all too familiar moaning and gasping of his little brother mixed with the grunting and groaning of whichever of his grown up friends happened to be visiting that day. He rounded the corner into the living room to confirm, seeing the bouncing tail and taut bare ass of their neighbor Mr. Spencer, the German Shepard who lived next door. Mr. Spencer's wife tended to work late most days, an opportunity which he often took advantage of by pounding out the pent up sexual frustration of his loveless marriage on the little cub next door. You'd never catch Jake complaining though. The young husky pup still had on his sneakers and basketball cap, loose shorts hanging around one ankle as his own curled tail scrunched up against the older dog's stomach each time Mr. Spencer's cock pumped into his backside. Jake gave his older brother a wink as he walked by. Knowing him, Jake was probably out practicing basketball with his shirt off right in front of Mr. Spencer's office window. He knew how much that worked up the older dog, and Jake absolutely loved to tease. Rex slapped his neighbor on the ass and headed back toward his bedroom. Haven't seen you in a few days Mr. Spencer, hope you got a big load saved up. he grinned as he walked away. This was confirmed shortly afterwards as he heard a load groan and a hard irregular thrusting as the German Shepherd climaxed inside his little brother. Once in his room, Rex began stripping off his own clothes. Tossing his shirt into a pile of dirty laundry on the floor, next popping the button off his shorts and dropping them to the ground, kicking them off along with his boxer briefs. He wrapped his paw around his cock as he flopped back naked on his bed, stroking himself at the recent image of his little brother getting pounded on the couch by their next door neighbor. The teenage husky closed his eyes and moaned softly to himself, precum dripping onto his bare belly fur, getting himself nice and hard for what he knew was coming next. Like clockwork, Jake was at his bedroom door moments later. He had kicked off the basketball shorts entirely, but still wore his sneakers and cap. He walked carefully towards Rex's bed, clenching his ass cheeks tightly together to keep from leaking on the carpet. You want sloppy seconds big bro the pup grinned, looking up at his older brother stroking himself and already knowing the answer. Get up here little butt slut. Rex answered back, patting the bed next to him. Jake nodded and climbed up onto the bed, taking it carefully so his ass cheeks would stay clenched. As Jake moved to straddle his older brother, he had no choice but to relax his backside when he spread his legs, releasing a huge splash of warm spent cum that fell all over Rex's belly and groin, soaking his soft pubic and belly fur. Sorry about that bro, Jake winked and adjusted his baseball cap. He wasn't actually sorry at all, in fact he knew how much his cum dripping tail turned his older brother on, a fact he often used to his advantage. Rex groaned and grabbed his younger brother by the hips, thrusting his rock hard cock up into Jake's tail and burying himself in one hard thrust. Fuuuck Jakey, there's no way that all came from Mr. Spencer! Rex moaned as his little brother started riding his cock, matching thrusts and pushing in him deep, further splashes of cum gushing out with each motion. Yeah... honestly this is like... sloppy sixths... the younger husky looked up at his brother, slightly embarrassed of his proclivities, but not so much that he would ever think about stopping. Holy fuck, six bro! Who else besides Mr. Spencer Rex groaned out in lust, knowing all those other loads were now soaking into his fur as he became ever more eager to add his seed to the pool. Yeah, um, Mr. Spencer twice, one of dad's carpool buddies in the morning, there was also a delivery guy who came by earlier, and that pizza guy I really like came by with lunch. It's been a busy day. Jake huffed, stroking his own cock as he bounced on his brother's shaft. Oh fuck Jakey, and you didn't use condoms with any of them he dug his paws into his brother's hips to get better leverage as he thrust upwards. Fuck no! the husky pup dismissed immediately, doing his best to look offended at the notion. Haha, that's a good little slut. Once I've filled this tail how about I invite a couple friends over and we see if we can break the two digit mark, huh Rex teased, knowing it wouldn't be long before he blew his load with dirty talk like this. Unnffff, fuck, really Rex You think I can Jake swooned, his puppy cock going rock hard at the idea. He may not have been old enough to cum yet himself, but he more than made up for it by making sure everyone around him was well serviced. I know you can Jakey, that little tail is gonna be so, sooo, sooooooooo... Alex groaned out loud as his cock erupted hard inside Jake's sloppy, cummy tail. Another blast, and another, coating his insides with seed and mixing with every other load inside the young pup's backside. His eyes were tight shut as his hips rocked and thrust, emptying every last drop into his slutty little brother. ...sooooooooo full. he finally finished, taking a deep breath and looking down at Jake's blushing face. I would really like that bro, please... Jake moaned softly. He adjusted his weight, resting back on his hind paws and causing a gush of cum to spill out and wash over his brother's balls. Rex shivered in pleasure and reached over for his phone, his cock still buried in Jake's tail as he dialed up his friend. Hey man, you up to anything right now I've got a little toy you might want to play with. Yeah Hey phone up the rest of the team too, bring whoever you want. Yeah. As long as they're horny and down to fuck, who cares Alright, bye man, see you soon. Rex hung up and grinned at his little brother. Hell, may even break 20.
