Kay and Master
       
       “Ugh… What does this have to do with martial arts, master?” Kay grumbled to himself, leaning against the door to his master’s home and crossing his arms. He’d come to visit the old coot for their regular training session, but the old man wasn’t cooperating. He was already drunk by the time Kay had arrived. 
       
       Of course, he had an excuse. “Proper relaxation- I mean, meditation is an important part of mastering the body, young pupil…” The geezer was so sloshed he could barely talk, and he still paused to get another drink of sake in before he finished. “And… um… to practice your own meditation, you must first learn to assist others…” He raised a paw and nodded, seemingly confident about how profound he was. 
       
       Kay wasn’t impressed. “I’m not giving you a foot massage, old man!” The young, striped cat rolled his eyes, and his tail flicked angrily. The old man had all but begged him for a foot rub, but he was way too proud to lower himself like that, even for his master. “If you’re not interested in teaching me anything real, I’m going home.”
       
       “Oh? I see…” Master sighed and laid a bit more heavily in his chair. He also made a point of stretching his feet out. Kay couldn’t help but notice.  “Well, if you don’t want my instruction, I suppose that’s that.” 
       
       He was speaking pretty definitively, enough to turn Kay’s head at least. “Are you serious, old man?” Much as the young cat didn’t like taking orders, the master had taught him how to use a sword, and he still had a lot left to learn from him. “Are you saying if I don’t rub your feet tonight, you won’t teach me at all anymore?!”
       
       Master barely responded, dozing off in his chair. What response he did give made the threat very clear though. “Oh, what a shame it is to lose such a prominent student…” 
       
       Kay was pretty sure that his master wouldn’t follow through with the threat. Hell, he was probably so drunk right now he wouldn’t even remember the threat. But the idea that he might not be able to keep training was seriously pissing him off just thinking about it. He couldn’t risk it. “Damnit, old man.”
       
       He continued to grumble while he got down on his knees in front of the old jerk. Just getting close to him in this state made his nose twitch. The old man had been pickled since this morning probably, and he smelled like it too. And it only got worse when he picked up his master’s foot. Everything about it smelled overwhelmingly sour. 
       
       “You’d better be grateful for this, master…” Kay held the foot as close as he could bear and steadily started to rub at the sole. 
       
       The old man was pretty obviously grateful at least, letting loose a long sigh and even a few moans. “Oh yes… thank you, Kay….” His sighs grew longer with each push Kay made against his paw. 
       
       Kay steadied his breath and focused. The young cat hadn’t done this before, but if he was forced to anyway, he chose to practice using every skill he had. This may have been the first time working on his master’s feet, but it wasn’t the first time he had given the old man a massage. He knew to press on the tightest muscles and to be gentle but firm. 
       
       Each press got a new moan going until the old cat was groaning with a passion that bordered on sexual. It made Kay’s ears twitch. 
       
       “Sounds like you’re getting your rocks off over there, old timer…” The young cat was sweating. The smell was getting worse the longer he worked, but he wasn’t hating it as much as he expected. He had even had to start biting his lip to keep himself from smiling while he worked. He didn’t stop himself from pulling the old man’s foot closer though.
       
       Before long, the sole of the old cat’s foot was practically touching his nose, and the smell was becoming even more overwhelming. It was becoming really clear now that it was sour and bitter like aged vinegar, alcohol that had turned into sweat at the old cat’s soles. For some reason, Kay was starting to like it. 
       
       “Mmm… right there, Kay.” Kay looked up at the sound of his name. He was feeling weirdly cautious when he peered over the foot. The old man was drooling like crazy. It looked like he had dozed off.
       
       But that wasn’t all that Kay noticed. He couldn’t help but spot an unsightly bulge in the groin of his master’s loose pants. “Damnit, I was right, wasn’t I? You old pervert.” The young cat was whispering for some reason. Clearly, he was worried about waking the old man up, but he wouldn’t admit it. What he would admit to though, was curiosity. 
       
       Kay turned his attention back to the old cat’s foot, wondering just how far he could take this massage now that he had fallen asleep. His curiosity was getting the best of him, and his youthful blood was starting to boil. If someone had asked, he’d have said he was angry at the old bastard for making him do this only to fall asleep five seconds in, and he’d add that what he did next was meant to wake the old jerk up. 
       
       In all honesty though, he was aroused. When he reached out with his rough tongue and ran it hard over his master’s foot, he was absolutely getting off on it. It tasted exactly like it smelled, but somehow worse. It was vinegary, bitter, salty, and even a little bit sweet. By all means it should have absolutely disgusted him. Once he started licking though, he couldn’t stop. 
       
       All the old cat did was snore while he licked. There was the occasional groan and a half-breathed laugh, but outside of that it was clear the old man was out like a light. That meant his student was given free rein to do whatever he wanted. 
       
       So, he kept licking, getting his tongue all over the fur and skin of his master’s paw. Eventually he couldn’t even pretend to deny his own arousal, and while he rested his tongue against the old cat’s heel and his nose against the old cat’s sole, he reached his free hand into his own sweats. 
       
       The shock of pleasure caused by his jerking made the damn old cat’s smell even better. It started to smell like it was reeking of arousal now too. He knew the old perve was getting hard, probably even having some sort of filthy dream. That was probably showing up in his sweat. 
       
       “Guh… b-bastard…” Kay started to quake surprisingly quickly. The arousal was blowing his young mind. He squeezed his cock tightly in his paw, trying to hold himself back, but he didn’t pull his master’s foot away. In fact, he started licking more intensely, focused specifically on the sweetest and sourest part of the old pervert’s soles. 
       
       It wasn’t very long before he couldn’t lick any more. Instead, he had to bury his face in that sweaty foot just to keep his meowing from waking the master up while he came. 
       
       By the time he was finally able to pull away, his paw and sweats were absolutely soaked, and he was loopy from lack of oxygen. “S-shit, old man… Don’t you ever wash?” He complained and tried to steady himself, but his ears were rolling back while he looked up at the snoring geezer. The old man was rock hard, tenting in his pants now. “And don’t you ever get off either?” 
       
       Kay bit his lip and pulled away at long last, letting the foot fall lazily to the floor. He couldn’t stop looking at the master’s cock now, and his own dick was still rock hard in his paw. Thoughts of what he could do to the old pervert were rushing wildly through his head and threatening to make him too dizzy to stand.
       
       “D-Damnit!” He swore and dashed off to the pond, stopping himself before he could do something he regretted, and cursing the old man on the way. “Freaking, old perve making me rub your feet.”
       
       As Kay stormed off, the old cat just barely roused, casually opening an eye just in time to see his student stripping for an emergency bath. “Hmm? Did I miss the massage?” An errant paw wandered to his groin, almost mindlessly. “Well, at least I got a bit of a show…” He drifted off to sleep before he could do much more about his arousal, but he was lucky enough to catch his young student bending over just before drifting off into some sweet dreams.
