“Hush, Kosaku. You’ll get us both fired.”Kosaku slapped his hand over his mouth and furtively looked at the office door. Kira didn’t really think they’d be caught, but it was fun making the man nervous.“What do you think our supervisor would say?” Kira asked, his hand pressing against Kosaku’s quivering chest while his other worked the man’s pants open. “Seeing your legs wrapped around me, seeing that desperate look on your face?”Kosaku shut his eyes and pressed his hand more fervently against his mouth at the teasing, seeming overwhelmed at just the thought.Kosaku’s hands flew to Kira’s shoulders when his stiff cock was pulled out, a guttural noise leaving him on a labored breath. Kira grinned at the man’s sensitivity. It was pathetically endearing.“Kosaku,” Kira brought his unoccupied hand up to the man’s mouth. “You really have no tact.”“Sorry, I’m so sorry…” Kosaku whined the words against Kira’s palm and rutted emptily into the air, sliding forward on the desk to bring them closer.Intent on getting his own gratification from this encounter, Kira pressed the tips of two fingers against Kosaku’s lips, prompting them to open. He couldn’t hold back a small noise himself as he saw his digits delve into the heat, Kosaku’s pink tongue cautiously moving under them.“Open up nice and wide for me, darling.”If the pet name didn’t make the man melt, the hand that wrapped around the base of his cock surely did the trick. With an unabashed moan that made the hairs on Kira’s nape rise, Kosaku stretched his jaw open.Kira peered down his throat, pleased at the way he could see the man swallow, how his uvula moved minutely. He didn’t really know why he had asked Kosaku to do it, nor did he understand why it turned him on to an almost disorienting degree. He splayed his two fingers out so they pushed against the soft inner skin of the man’s cheeks, then brought them to his bottom teeth. He let them drag over the bumps and irregularities of the back teeth before joining together at the narrow front ones. The feeling of their spit-slick hardness made him exhale slowly and lick his lips.Kosaku’s dark eyes were lidded and watching him with burning need, yet he remained obedient and remained still as Kira repeated the action.“Naughty boy,” Kira tapped on one of his molars, “It looks like you have a cavity forming. It’s all that sugar you put in your coffee, no doubt…”Before Kosaku could even begin to look guilty, Kira grasped his cock more firmly and slid up, the dry foreskin pulling over it’s glistening head. A hot gasp blew over Kira’s knuckles as he brought his hand down, then back up. It was slow and torturous, but Kosaku clung to every touch, his body arching and trembling, his mouth still submissively open. He really was a good pet. Kira moved his fingers to the upper row of teeth, using one finger to push the man’s full lip up so he could properly give them a look. He always liked the man’s teeth, so often hidden behind the neutral scowl he always wore. It was a true treat getting to observe them so intimately, and he found his fingers roaming fervently in Kosaku’s salivating mouth. He let his index finger drag over the fronts of his incisors, his nail snagging on their sides. Beautiful, truly beautiful.Feeling himself closing in on acute pleasure, Kira got more bold. He brought four fingers together before delving back in, reveling in the softness of Kosaku’s tongue in contrast with the pointed solidity of his teeth. For compensation, he peeled back Kosaku’s foreskin and rubbed his thumb in tight circles along the swollen tip, smearing the slimy precum that gathered there and making the man whimper and shake.“Are you getting close, my dear?” Kira brought his fingers deep into the man’s mouth, his pinkie and index resting against his wisdom teeth while the middle two hooked into the back of his throat. Tears welled in Kosaku’s eyes and he gagged, but even still, the harsh sound was followed by a low whine. “How pathetic.”The words seemed to snap something in Kosaku. His body jumped before shivering violently, all while low, drawling whimpers hiccupped from his throat. Kira released the man’s throbbing cock and tried to step back to avoid the oncoming spurts of semen but Kosaku’s teeth snapped down on his fingers, canines digging into his knuckles and molars pressing tightly against his fingertips.The smash of teeth against his skin and the accompanying pain overrode everything else in his brain and he tumbled quickly and shakily into his own orgasm. His knees nearly gave out as his cock twitched and thumped against his thigh, his ejaculate quickly soaking the front of his boxers.Kosaku panted and released his fingers. “Sorry,” He mumbled, looking down to see the stomach of Kira’s shirt, now covered in thick stripes of runny semen. “I’m so sorry, Kira-san…”Kira pulled his hands to his chest, rubbing soothing circles into the small red indents the man’s teeth had left. Touching them left a soothing ache and made Kira’s cock dribble a few last spent drops.“A warning would have been appreciated.” He looked down his front, seeing the wet spots on the front of his slacks and his shirt.Despite the fact that Kosaku truly couldn’t have done anything in the situation and undoubtedly knew that, he quickly reached back on the desk and pulled a few tissues free.“I’m so sorry,” He said again, his brow knit in distress.Kira stood silently as he let the man clean his mess.Yes, Kosaku was a good pet.
