It’s Friday at 13:00 and Santiago, a dark gray wolf with red lines from forearms to wrists and 18 years old, passes by on his motorcycle to pick up his brother Daniel. He waits a few minutes in the sunlight, adjusting his guayabera (shirt) and unbuttoning it due to the hot day, receiving some confused looks from some children and parents. His white shirt with orange and Mexican pink prints contrast with the fur on his belly and chest, slightly lighter than the rest of his body. His black eyes look at the door of the elementary school and waits impatiently for the arrival of his little brother as his tail wags with some frustration, showing his wine-colored zig zag pattern. His ears perk up and the sun shows the same reddish hue on the tip of his ears as a young donkey with grayish brown fur steps out of the gate with his tail between his legs, his gaze darting to the wolf and then turning away, his face showing some embarrassment. * What? * N-no, it’s nothing. * Are you embarrassed to see me like this? * The others staring weirdly at you... * What's wrong with that? Daniel, 10 years old and with a white zigzag pattern on his legs and arms, resigns himself to sigh and tries to get on the bike, but his brother stops him with one arm. * Move your tail. * What? * Do it. The donkey's legs tremble as he obeys the young canine. A bulge of considerable size for his age bulges through the fabric of his beige shorts, throbbing slightly. Daniel just blushes and closes his eyes, trying to calm himself to get this over with as soon as possible. Santiago knows this happened from unbuttoning his guayabera, he sighs and caresses his brother's head gently, bends down and whispers in the little boy's ear. * You know... that's kind of cute. * R-really? * Yep... - Santiago "accidentally" pokes his brother's length with his knee, putting a little pressure on it. * H-hey! - Daniel mumbles and holds his breath, trying to avoid moaning in public - * Hehe, cute~ The boy woke up especially sensitive this day, and the feeling is stronger than usual. His legs give up and he tries to lean on his brother, hugging him and letting out a small moan that he tries to hide in Santiago's chest. He lets out a small laugh and caresses the donkey's head, kisses his forehead, licking it a little. Surprisingly, no one noticed the strange situation. * Well, get on the bike now. After a few minutes of driving through the noisy streets of their city they arrive home, having ignored the trees and colorful food stalls that decorated their path, the sun warming them in more ways than one as Daniel clung in an embrace to his brother's back. Their home is a modest one-story house in a low-income area, the paint on the outside is somewhat deteriorated and looks drab, as the surrounding houses are almost identical. But the afternoon light makes it look unique and special, although Santiago and his brother are already very used to this, and do not give it much importance. The wolf opens the door, allowing the little boy to pass first to drop his backpack and rest a bit before doing anything else. The door whips shut behind the canine, who sits down next to the donkey on the couch. His home is somewhat chaotic, beer cans surrounding a small armchair as if it were a wall, drawings scattered on the floor along with some crayons, but what catches the young man's attention is a half-eaten burrito al pastor, abandoned on the table. * You didn’t finish your food? The boy stays silent, bows his head and looks away, he already knows what will happen. * Let's go to your room. * But... It still hurts. * Then you should have finished your breakfast. Do you know how expensive those things are? * ... * To your room. The donkey sighs, his tail between his legs and his ears bent as he walks to his bedroom, his brother trailing behind him. The door opens, revealing a dark room with broken stuffed animals and empty lube bottles near the bed, as well as a pile of new condoms on a shelf by the window. Daniel sighs and sits on the bed, waiting for orders from his brother, who snaps his fingers as a signal to tell him to take off his clothes. It's a winter vacation weekend, Daniel heads to his room before his parents start arguing as they have for the past two years. The donkey, barely 4 years old, hides under the covers after playing some music on an old tape recorder, and under the covers he finds the decapitated body of one of his stuffed animals. Fortunately it wasn't his favorite stuffed animal, in fact he hated it, but what attracts him most at the moment are the growls that seem to come from under his bed. Somewhat frightened, Daniel clutches one of his blankets and peeks underneath, finding a young 12-year-old wolf chewing on the toy's head as if he had just hunted it. Returning to the present, the boy has finished taking off his clothes, and so has his brother. He looks up, showing shyness. This punishment is not something that frightens him, or that he hates, in fact he likes it. But he can't help but feel somewhat intimidated and embarrassed at times like this. Santiago averted his gaze and stared at the confused face of the little donkey, banging his head against the bed as he tried to get up. The boy couldn't help but laugh, even when the teenager in front of him asked him not to, but he ended up laughing too. Hours later they would discover their kinship, both embarrassed despite not understanding what they had just done minutes before. The donkey's legs still trembled and his belly felt warm, while the wolf averted his gaze, avoiding giving in to his urges again and trying to calm his breathing as well as his crotch. Both taking each other's hand, determined to hide this. * Come on, why so shy? * It's just... How many years have we been doing this? * Why the question? * It just... every time feels like the first you know... * I think it's cute * Hehe, my little brother's a pervert huh? * H-hey, you're the one who started this. * Are you sure? Remind me who sat on whose crotch? * I was little, it wasn't my fault! * "Oooh what's this hard thing? Can I see?" * Th-that wouldn't have happened if you hadn't had it! * I'm not to blame for my instincts, that happens to a lot of people when they see small things... Besides, from what happened today, you should know by now that this "thing" can't be controlled. Santiago takes a rope from the floor and uses it to tie his brother's wrists to the headboard, salivating a little as he does so. The little boy trembles, remembering how on other occasions his brother used to tear his plushies to shreds in front of him and use them to satisfy himself. He's been doing that since the week they met, but when they started living alone, he began doing it when he thought Daniel had to be punished. But Daniel realizes that this time it's different when he sees the young wolf tearing a stuffed animal's ass with his fangs and then putting lubricant on the donkey's member. * B-Brother? * Yes? * I-I thought this was going to be a punishment. * Oh, it is. But I also want to "reward" you for your reaction to seeing me with my shirt open... Besides, you got good grades, right? * Yeah... About that. * Leave it like that, don't say anything else or I'll change my mind. The canine inserts his little brother's member inside the stuffed animal, moving it slowly up and down while placing an arm around Daniel's shoulders to hug him as he continues. He licks his head affectionately, kissing it as the little boy whimpers and his legs tremble. Their lips meet in a passionate kiss as the teddy begins to move faster. Santiago puts pressure on it to further stimulate the boy, who ends up cumming dry quickly, still unable to create semen. His hips ramming the toy by mere instinct. Their lips part, momentarily joined by a trickle of saliva. * All right, now get off the bed, – Says the young man as he lets go of the toy, which moves with each throb of the donkey's member. * But... you tied me to the bed. * ¿And? * ... * You won’t listen? Daniel is confused, Santiago has done things like this before, and he knows what's coming, but he still doesn't quite get it. He sighs and smiles sheepishly at his brother, ducking his ears as he looks him in the eyes. The wolf smiles lasciviously and licks his lips, taking the donkey by the hips with both hands and turning him over, laying him chest down. Daniel is a little startled, but his member releases pre, dripping out of the stuffed animal. Santiago playfully bites his brother's butt, who squeals a little. The wolf bites with some force and scratches his sides, to which the donkey responds by reflexively kicking his belly. Santiago falls backwards to the ground, with his hands on the zone his brother hit. * ... Ouch. * I'm so-sorry! Are you okay? - Daniel turns to see his brother and tries to help him, but his hands are still tied. The young man just raises his arm and gives a thumbs up, indicating that he's okay. He gets up somewhat slowly and sighs, giving his brother a hard spank in reprimand. He turns him over again and looks into his eyes, gasping with "emotion" as he sees a couple of tears in the boy's eyes. He takes the stuffed animal on his cock and pulls it off hard, getting a small squeal in response. He sniffs the stuffed animal, enjoys its strong pre smell for a moment, bending his ears and closing his eyes to concentrate on it. He then grabs the stuffed animal by the waist with both hands and rips its head off using his mouth. He picks up another stuffed animal from the floor and repeats the process, watching as his brother sees each strand of his toys tearing apart one after another. He decapitates a couple more stuffed animals again and picks up a last one, a small stuffed German shepherd. He rips off its legs and arms with more force than he expected to need, making it look even more savage in front of the boy's eyes, who cries silently at the sight of his toys shredded on the floor. Santiago takes his underwear and rips it apart, inserts the mangled dog into the donkey's mouth to gag him and holds it closed by tying his snout up with his torn underwear. The wolf can't resist his urges much longer, so he places the boy's legs over his shoulders and enters his brother without using lube. The little boy cries out from the pain as his brother lets out a small laugh and caresses his legs, letting them rest on his shoulders as he thrusts and tries to restrain himself so as not to cause serious damage to the boy. Daniel's breath hitches, tears run down his cheeks and he bites down hard on his toy. But even though he's scared he can't stop moaning and blushing, his cock is still erect and he's just about to dry cum again, he's enjoying it in spite of everything. The wolf is behaving more and more feral, and can't stop salivating and wagging his tail for the pleasure and joy of succumbing to one of his most basic instincts. He ends up biting Daniel's thigh, who immediately starts kicking and trying to remove his legs from Santiago's shoulders, but Santiago doesn't even flinch and bites harder and harder, although without any real risk. The canine's knot strongly attacks the equine's backside, his legs also tremble and he buries his claws in his vulnerable brother's sides. His hands shake as he holds back his strength so as not to really hurt the boy, but his fangs have already started to draw a couple of drops of blood, which only fuels his aggression more, especially when the blood touches his tongue. Daniel can no longer stand his brother’s pace, he already came again long ago, and now he is about to do it a third time. His member aches from overstimulation despite not having touched it in a while, his hips tremble and his body tries to push to get his brother out, only succeeding in massaging his member and encouraging him to continue, as it feels tighter than before. Finally, Daniel cums for the third time. He can't even think clearly or breathe normally, he feels very tired and wants to sleep. At his age, even without really having a high libido, he should have high stamina in this regard, but this seems to be the exception. Santiago manages to get his knot into his brother and cums exaggeratedly, howling in an attempt to show everyone that Daniel belongs to him, even if there is no one there to hear. Santiago keeps on ramming, thrusting his knot in and out over and over again in the trembling body of the donkey, who can only think of the warm sensation in his belly from his brother's semen. At the end, the wolf is exhausted and falls on top of Daniel, but unlike his brother, he recovers very quickly. This is going to be a long night.
