Man's best friend

      When Ichirou invited Riko to spend some time with him, Riko had a different vision of how the evening would go. Being tied down to a breeding bench wasn’t on his list.       When the last strap is secured, Ichirou says, “I want you to meet someone.”       Riko can only make a questioning noise through the gag that has been showed into his mouth earlier, but his brother seems to understand him.       “You’ll see.” The vague response does nothing to calm Riko’s nerves. “I think you’ll get along. He’s very dear to me.”       Riko wracks his brain for an answer on who might be joining them, but he comes out blank. His brother doesn’t have friends — only trusted accomplices, though he never speaks of them as kindly as he just has.       “Wait here,” Ichirou says, and Riko starts squirming as his fear spikes up. Is his brother going to leave him here like this? What if someone sees? The thoughts spiral, fueling his panic. Seeing the distress, his brother caresses his back. “I’m not leaving, shhh.” The touch is grounding, and Riko’s breathing slows.       As Riko calms down, Ichirou opens the door. Something walks in, and what sounds like paws scratch the floor.       A dog? Riko thinks with surprise. Since when is his brother fond of pet animals?       His suspicions are confirmed when the newcomer appears in his line of vision. The dog is big — a Shikoku breed if Riko remembers correctly — moat of his fur a beautiful black color. The dog sits down obediently when Ichirou tells him to, looking up at his master with clear adoration.       “Meet Kuro,” Ichirou says, petting the dog.       Riko nearly rolls his eyes at the name. It’s cliche, but to he perfectly honest, he didn’t expect anything creative from his brother.       “Come here, boy,” Ichirou says with gentleness normally reserved for his brother. Jealousy twists deep in Riko’s stomach, and he looks at Kuro with loathing while the dog trots after Ichirou towards Riko’s behind.       A puff of air on his hole makes him squirm, unease gripping his chest tightly. Surely Ichirou wouldn’t…?       Riko nearly jumps out of his skin at Kuro’s excited woof, the sound loud and unexpected in the quiet room.       “See? He likes you,” Ichirou says, and Riko can hear his smile. “Go on, boy,” he says to the dog.       What follows is so bizarre that Riko’s brain short circuits for a second. Something wet swipes at his hole over and over again, and it takes him a while to connect the dots. Kuro is eating him out.       He shudders in disgust as the dog licks his taint. He really wishes his body stopped reacting to the dog’s ministrations, but it’s like his dick has a mind of its own. Shame colors his cheeks and makes Riko yearn for the ground to swallow him whole as his cock hardens.       “I’m glad you’re bonding well,” Ichirou says, his voice holding a rare gentle tone. “Back,” he commands the dog, and the tongue leaves Riko’s hole alone for now. It doesn’t stay this way for long though because something slick puts pressure against it. Riko fights against his bonds to make and escape, but the leather straps hold him in place.       “Shush,” his brother says. “It’s only my finger. I need to prepare you.”       Prepare for what? Riko wants to ask. Surely the dog won’t…? No, that’s absurd, he dismisses the thought.       One finger quickly becomes two, and Riko groans as they hit his prostate, making him see stars.       “That’s it.” Ichirou massages the spot repeatedly. “Good boy, enjoy yourself.”       Riko’s cock is rock hard now, but no matter how good the fingers feel, it isn’t enough to make him come, and he has no way of rubbing it against the bench below him. He whimpers, hoping that his brother will understand the pressing need.       “Impatient, huh?” Ichirou pats Riko’s side. His fingers leave Riko’s hole, and he shushes his brother yet again. “I’ll give you something better in a second. Kuro, come here, boy.”       When Riko feels the dog leaning over him, he starts squirming in earnest. Horror grips his throat as Kuro’s cock nudges against his asshole. He screams through the gag, but his protests fall on deaf ears. The cock stretches Riko’s hole painfully despite the earlier prep, every inch rubbing against his sensitive walls. He clenches his muscles to stop the intrusion, but it does nothing but excites the dog more.       Ichirou’s shoes clack against the floor, and the man crouches before Riko. “Relax,” he says, wiping the drool that keeps leaking out of Riko’s mouth. “He just wants to get to know you better.”       Riko screams as Kuro pushes his cock forward and bottoms out. Cold sweat beads Riko’s skin as the pain radiates from his hole, the muscles stretched to their limits. He breathes deeply through clenched teeth, hoping to alleviate the pain.       “Good boy, taking it so well,” Ichirou says, ruffling Riko’s hair.       Riko would love to throttle his brother if given the chance. His eyes must betray his murderous intent because Ichirou smiles condescendingly. “It’ll feel great in a minute.” Riko has serious doubts about it.       Kuro starts to move, and the burning pain brings tears to Riko’s eyes. He blinks, trying to clear them away, but even more come in their place. The dog is panting, his breath hot against Riko’s neck, and Riko hopes that it’s a sign that it will be over soon.       A hand cups his cheek. “Get ready,” Ichirou says, a gleam in his eyes.       Riko makes a questioning noise, but his brother only chuckles. “I’d hate to ruin the surprise.”       Well, that doesn’t sound ominous at all.       Kuro sheathes himself fully before Riko’s guts are flooded with hot cum. That isn’t what worries Riko, though. The more pressing thing is a pressure against his asshole, stretching it painfully even more. More tears flow from his eyes, too tired to scream. He looks at his brother’s smiling face, hoping for some explanation.       “It’s a knot. We need to wait for a few minutes for Kuro to pull out.”       The words only bring more shock. A dog has knotted me,Riko thinks in disbelief. What would anyone think if they saw him like this — the King of Exy, reduced to be a dog’s bitch?       Ichirou wipes Riko’s tears away, and then his right hand closes around Riko’s cock, which have gone soft during the ordeal. The younger man jerks in his bonds, and whimpers as it disturbs the knot buried in his hole.       “I want you to enjoy this,” Ichirou says, quickly bringing Riko back to full hardness. Despite the muffled protests, it takes Riko an embarrassingly quick time to come, spilling all over his brother’s hand.       “Good boy.” Ichirou pets Riko’s head, the touch barely registered by the bound man. “I think Kuro would love to see you more often. What do you think?”       Riko knows that regardless of his answer, he will be meting the dog again soon.
