"I can't believe you wanted to go out to dinner at a diner, Carson," dad grumbled at me, setting down his menu. 
"I like the food here, dad, I can't help it." I grinned and sipped my water idly. "Besides, it's my birthday, the rules say we do what I want, remember?"
Dad grumbled more, his ears laying against his head and going more than a bit red. "I know, Car, but... I was expecting you to pick a steak-house or something!"
I rolled my eyes. "Dad, we're rabbits, we can't eat steak anyway."
"Because that's the only thing steak-houses serve!" Dad snorted and rolled his eyes, too. 
A waitress stepped up, chewing some gum and grinning at us toothily, sacharine sweetness in her manner. Always hate customer-service workers for that. "Whatcha want, huns?"
"Ask the birthday boy," dad teased, smirking at me. 
"Oh, hun, it's your birthday? Want me to make somethin' special for ya?" The waitress asked, leaning down. 
"Nah, I'll be fine with a salad, uncooked carrots, and a side order of apple-slices." I handed her the menu.
"Same for me, but a slice of carrot-cake too. With a candle." I rolled my eyes. I was very tempted to kick my dad under the table... but no, better plans were afoot.
"Sure thing, hun! And happy birthday!" The waitress beamed at me before bustling off. 
"So," dad said, grinning at me, "want to open your gift now or shall we wait until dessert rolls through?"
I rolled my eyes again. You'd think the ol' jerk would ease off on the teasing for a day! Guess not! "Sure, now's as fine a time as any." I leaned against the table, toes tapping, causing my flip-flop to slap against my sole. I'm sure dad heard it, he knew that sound well, after all. I could see his ears going a bit more red with each.
I made sure to tease him a bit more, grinning as his nose twitched, his ears reddened, and his muscles flexed beneath his shirt. He'd just gotten off work when he came in and asked me where I wanted to go for dinner, so he was still in his work-clothes. A tight polo and khaki pants, showing off my dad's... well, bluntly impressive musculature. He works out quite often, and works it damn well, I can't lie. 
Beneath the shirt his fur was a dark gray, almost black, with his eyes shining as green as grass. Opposite him, I take more after my mother, white fur and gold eyes and a runner's build. Track, keeps me fit and... well, let's just say there's fringe-benefits included. 
Dad fiddled with something in his pocket and pulled out a small box wrapped in a bow. It was a bit squished, but I didn't hold that against him. 
"I... hope you like it, Car, been looking for something like this for ages," dad mumbled, actually a bit... embarassed by the gift.
I took the box, undid the sadly flattened bow and slipped off the lid. I blinked at what I saw, two bangles, one black with green charms dangling off, the other silvery-white with gold charms dangling. I took them out. The white was substantially larger, but both were too big to fit around my wrist comfortably.
"What's... what're they for, dad?" I was, I'll admit, very confused. 
Dad blushed deeper and cleared his throat. "We... well..." he slid a foot along the floor and gently nudged the toe against the back of my own, pulling it upwards. I let him guide my foot up until it was on his lap. He took the black bangle and moved it beneath the table.
It took me a moment but I got the idea as soon as I felt it. Oh dad, you kinky fuck. I smirked and dad definitely saw that, saw I approved. I wasn't going to make things easy for him, of course, I shifted my foot slightly, letting my flip-flop fall to the floor and gently grazed my toes along his thigh. I heard him gasp and felt his hands quivering as they worked to attach the bangle around my ankle. 
Me, I just sat there, smirking at my dad, teasing him with rubs to his belly, his thighs his... other areas I knew he'd appreciate. When he finally let go he set his shaking hands on the table.
I lowered my foot and shifted, bouncing my foot and hearing the quiet jangling of the charms. I know dad heard it too because he was twitching with each faint chime. 
I gently rubbed a foot against dad's ankle, toe sliding up the leg just slightly to rub over his bare fur. He never wore anything but no-show socks, so he could feel my sole against his leg, and I could tell he loved it. 
Dad and I have... a unique relationship, shall we say. Bluntly put, we're both foot-sluts. And since mom fucked off to points unknown, that left dad with a mountain of bunny-hormones and no outlet. Come the time when I started having... urges of my own... well let's just say it was a hell of a start for both of us, and neither of us has any desire to go back.
We aren't in love, or anything, we love each other, of course, but... getting to spend time like that is special and fun. It means more than just a circle-jerk at friends or a two-bit hooker. 
And teasing each other is helluh fun, too!
Don't think I'm the only one who gives it, dad does too, the bastard, but I could tell that he was definitely feeling the heat today. Hell, I could smell it on him!
The waitress came back and set our plates in front of us. Dad grinned nervously and asked for some napkins. The lady brought them out and told us to holler if we needed anything.
Nah, honey, we're all set!
With the food delivered we took a bit of a breather to eat. A bit, anyway. I still kept teasing my ol' man mercilessly as we both ate, rubbing my sole along the shiny leather of his shoe, toes squeezing against his ankle, brushing up his shin. I wished I could feel his too, but alas, it wasn't my turn yet. 
I know I said I liked the food, I do, but it had absolutely no effect on me, it was all my dad, his quiet groans, his blushing, his lip-biting, toe-clenching, pants-bulging need that was getting worse by the second that had my entire focus.
The cake was brought out, candle and all, even lit. The lady waitress gave me a big slice as dad set his pay for it all. 
As the lady disappeared, I leaned down and gave the candle a puff of air. "I wish that my dad will finally let me be the top. Right here in the restaurant."
Dad's green eyes widened as he heard that.
"Rules are rules, dad. I do what you say on your birthday, same's true for me!" I grinned cheekily at him. He could have said no and that would have been the end of it, I never would have pressed or bothered again, but... I wanted to try something new, and I'd definitely make sure my dad enjoyed it, too. Or try to. If not, well, that'd be the end of it too.
Dad fidged terribly, plucking little bits off the napkin and setting them on his plate as I ate my cake. Didn't taste it either, I just let my dad come to a decision.
"Alright," he mumbled quietly, looking down, embarassed as all hell. 
I blinked... and perked. I didn't think he'd actually let me!. Finally!
I grinned wide and finished my cake. "But first, dad, don't you think you're a bit... under-and-over-dressed?" I teased, hooking my foot behind my dad's and tugging at it. I'd seen the reason behind the gifts as soon as he'd started, and I could tell he was eager for his side. He worked and wriggled his work-shoe off carefully before lifting it up and resting it on my lap.
It was warm against my thigh, big, heavy, strong. I had to fight hard to keep from blushing as bad as dad was. I pulled the bangle out of the box and slid it under the table, letting my fingers graze along my dad's big sole and making the old man squirm. Oh, how I'd enjoy my plans with him! 
I shifted forward and let his big sole press against my belly. He instinctively flexed his toes, tugging at my shirt as I attached the bangle. Poor guy's eyes were clenched tight and I knew he'd be thumping his foot if it weren't for stern control. 
Rabbits, we can't help it when we're happy.
When the lady brought back the check, dad lowered his foot and slipped his shoe back on, slipping the receipt into his pocket and thanking her for her service. I watched him stand up and waddle his way to the bathroom, trying hard to hide his incredible erection from being noticable. 
God, though, seeing the peak of that bangle on his ankle was... very nice, I can't lie.
When enough time had passed, I sauntered my way to the bathroom as well, out of sight and into privacy.
Two steps in the door and I could already smell my old man. He gets this incredible scent when he gets boned up, and oh, lord does it do things for me! I stepped towards the biggest stall, the one reserved for bears or rhinos, and stepped in. Of course he didn't lock it. I, however, did.
My dad was sitting there on the toilet, dick hard as steel, leaking like a faucet. He sat with his legs spread, toes clenching on the floor as he saw me. I smirked and started sliding my own clothes off with teasing slowness. He was practically whining by the time my own dick came into view, a carbon-copy of my dads, uncut, thick, veiny as hell, and like his, hard-wired to my feet. 
Dad was fighting hard not to stroke his dick. I knew he could manage several loads in a sitting, but he knew I wouldn't want him to waste any of them. 
"Come on, dad, up you get, we're gonna do this right!" 
Dad blushed terribly, his ears flat against his head. "Don't... go too hard, Car..." 
I stepped up and leaned down right into my dad's face, giving him a kiss on the lips, pressing our dicks together. I felt him shudder as his dick twitched against mine. He grabbed onto my hips and moaned into the kiss, unable to help but hump against me.
When I broke it, he panted, tongue hanging from his mouth and looking distinctly dazed. "Dad, come on, you know me better than that. I'm going to make this fun for both of us, just like you always do for me."
And it was true, dad always fucked me just right, asking how he's doing, angling just so he hits the perfect spots to drive me wild, giving me those incredible toe-clenching, bed-grabbing, pillow-biting orgasms. I would do the same to him, by god, I'd get him to blast his load to the fucking ceiling!
Dad nodded, shuddering again and standing up. Upright, he was a bit taller than me, and god did I love that, I pulled him down into another kiss, lifting up on tip-toe to manage, pressing myself against his rock-hard body, feeling how hard his heart was pounding. I didn't mind that dad was leaking on me, lord knows I'd definitely need the lube! 
Finally, I stepped back and dad knew it was time. He turned around and got on his knees onto the toilet. I saw his little bob-tail flag and I had to put down the urge to call it cute. Bunny tails are cute, damnit, don't judge me! 
I saw his toes clench, still wrapped up in their socks. Oh, god, how I wanted to give them attention. I would, too, but not yet, not until I gave my dad's hole some first! 
I dropped to one knee and stuffed my snout right between his cheeks. The poor ol guy gasped and arched, toes clenching harder as I began assaulting his hole with my tongue. Dad was always a clean-freak, showering before work, and usually when he got home. He'd always smell like soap, and I certainly love that smell, especially when he hugs me or just... hang out. But sometimes, like now, when his hormones are raging, when rut is in the offing, after a long day at work... god he smelled fucking amazing.
Musky, not ripe, not dirty, musky. The scent of a male poking through the soap, the inimitable aroma of masculinity. I couldn't help but thrust at nothing as I held my dad's ass-cheeks apart and assaulted his tight little pucker with my tongue. I fucking adore that scent. Not just on my dad, but on any male, but my dad's is absolutely the best. His dick, his pits, his balls, his... okay, I admit it, his feet too. All of it just smells incredible to me! A whiff and I get boned up like you wouldn't believe, and I was boned up almost as bad as dad, just then!
But he was relaxing, he was getting into the sensation, beginning to ease into the pleasure. He was biting his lip, quivering as he ached to moan out his pleasure, but we were in public, he knew that wasn't safe. But that obscenity, that danger was intoxicating for him too. 
He got off on it just as bad as me, we'd done it more than a few times out and about. Park restrooms after a run, at the gym after a workout, at the beach, in the woods after a hike (and in the tent), we were horndogs both, and nothing could stop us when we got boned up.
I pulled my tongue back, panting and feeling a bit drunk in the best ways. God seeing my dad's broad back, seeing his tail flagged up, seeing his toes flexing and clenching... god I'd enjoy pounding him! 
I brought a hand down and caught some of the ungodly drippage from my dad's dick, swirling a finger around beneath his overhang of foreskin and making him yelp and soak my palm. I just grinned and gave my dad's ass a gentle nuzzle as I brought my soaked hand up and began smearing it along his hole. He began tensing back up so I shifted my free hand to my dad's foot, stroking and pressing and massaging it through the thin, moist fabric of his sock. I knew exactly where he liked, where the tension was, and he practically melted. 
Perfect for the finger to slip inside. I didn't shove it in in one go, of course, I dipped the tip in and pulled it back, working a different one in to get it nice and slick before reannointing with pre. Dad was oscillating hard between pleasure and nerves and relaxation, keeping him on the edge of bliss. 
He didn't even realize I'd slipped a second finger in, and then a third, working them this way and that inside, rubbing at his prostate and driving my ol' man wild.
It wasn't until I pulled them away that he went limp, panting and looking over his shoulder at me like he was wondering why I'd stopped.
And then it hit him, I hadn't stopped, I just hadn't even started yet! 
"On your back, dad, I want to see your face," I said, standing up.
Dad shivered and shifted, sitting on the toilet. I lifted his thick legs up onto my shoulders, giving his shin a kiss and nuzzling at the bangle. I could see him smile at that. He knew he did a damn good job with the gift. 
I leaned down, pushing dad's knees towards his chest and giving him a kiss. "Hold onto your legs, dad, breathe, I'll be gentle, I promise." I hotdogged my ol' man's ass a few times, bumping his balls with my dick tip and smearing them with my pre. I leak almost as badly as he does. Especially just then.
Dad hooked his hands behind his knees, looking up at me nervously. I settled my dick at his hole. But of course, that wasn't going to be the end of it, oh no! I shifted my head to the side and nipped the edge of my dad's sock and tugged it down and off. He gasped as his sole was bared, his toes clenching in my face as they slipped free. I grinned cheekly and dropped the sock to the side and instead assaulted that sole. 
I mashed my snout against it, licking firmly, running my tongue all over it and making my dad need to physically bite harm to keep from groaning. In that instant of pleasure I eased my tip into his hole. He felt it, he felt the stretch, felt the heat of my pre flooding into him, no doubt, but the sensation of his hard-wired sole being assaulted was overwhelming to him.
God damn, though, ol' man was tight! I'm hardly a virgin back behind, between dad pounding me like a rut-bunny would and all my school fuck-buds, I've taken quite a few dicks in my time. But I've certainly given some back! My favorite is the bigger guys, the bears, the elephants, the rhinos, the hunks who'd never be seen taking a dick. Them, them I love bending over, perching on their ass, toes gripping into their hips and pounding down onto their prostates like a fucking jack-hammer. I call that move the jack-rabbit jack-hammer. Brings them back begging for more every fucking time!
I eased slowly forward, panting and groaning myself, the mixture of incredible tightness, my dad's delicious sole, the feeling of the big hot foot against my face, the fact that we were doing it in a fucking restaurant bathroom... god it was driving me wild!
I eased off on the assaulting and let dad get used to it. His toes clenched and flexed as the echoes of pleasure coursed through him. I felt his hole clenching and flexing around me. 
"Doin'... okay dad?" I asked, panting and nuzzling at the bangle some more, making it jingle quietly. 
"F...fuck... fuck kid... didn't realize... you were... a natural at this!" 
I smirked and leaned down, giving my dad's neck a gentle nibble. "Please, dad, I've fucked plenty of studs!" I laced my fingers between my dad's toes and eased a bit further in, making my ol' man groan. "But I can't lie, you're the sexiest one to date!" 
Closer and closer I eased, gentle humps working myself further into my dad's hole, pausing when he grunted or tightened up, only to ease in more as he relaxed. Finally, though, my hips met his ass and held there, just feeling the pressure and pleasures of our partner's body. 
"Every inch, dad," I said, lifting up and planting my dad's big feet against my chest. I gave his toes a teasing lick , making them flex. "Now the fun begins!" I slowly began drawing back, I could feel my ol' man quivering, feeling the sudden aching emptiness. Luckily for him, he woulnd't need to wait!
I thrust forward firmly, hilting into his hole once more and making him gasp. God but it was hot seeing him so turned on! I felt his pre hitting my chest every time I thrusted home. I tried to stifle the groans, the moans, the growls, and dad clearly did too, but he was on the losing end of things and he had to cover his mouth with both hands to keep his lust in check.
And then we heard the door open.
I pressed to the hilt into him, muscles locking in fight-or-flight as we heard whoever it was stepping up to the urinal. Dad looked at me with wide, scared eyes, still holding his mouth.
I smirked down at him and leaned back and ran my tongue teasingly along his sole, gently, slowly, tracing along the edge, dancing over his thick toes. 
Poor guy's eyes went crossed as his breathing wobbled, his hole quivering around my dick as whoever it was pissed on without being any the wiser to the obscenities being inflicted upon my dad only a few feet away.
The patron finished up, stepped over to the sink, washed their hands and was gone, all while I was giving my ol' man's sole a thorough tongue-bath. 
As soon as the door closed, my dad released his mouth and wrapped his arms around me, pulling me down suddenly and snarling right in my face. "You... are an asshole... Carson Edward Gents." 
I just smirked and gave my dad a kiss full on the lips, giving him more than a taste of his own scent. I felt his hole clamping like a vice around my dick. He liked it too! "Love you too, dad!"
"You better fuck me hard, now!" He growled, his legs around my waist, keeping me held in his hole. 
"Sir, yes sir!" I leaned back and gripped my dad's ankles, using them as hand-holds as I began fucking my ol' man properly. It was adorable seeing the old rabbit going from "angry" to a whimpering slut in the course of a few easy thrusts. Every time I shoved home, his toes clenched, his sole wrinkled, and I had to fight the urge to rub my cheek against them. 
And then I started aiming properly. But more, I started pounding in the way that only a rabbit can manage! I angled my hips, leaning back and started thrusting upwards, right against my ol' man's prostate. I felt the gland, swollen, pulsing and flexing against my dick tip on its path inwards. I saw my dad's eyes go wild as I jack-hammered my hips up into it, panting, growling and snarling myself as my old man hung on for dear life.
His eyes were going crossed, his muscles clenching, his balls dragging up as he prepared to let loose the mother of all bunny loads. And get one of his own, too!
I could feel my own orgasm building hard, fast, just as brutally as I was bringing my dad to his!
And then the colossal fucker sandwiched his feet against my cheeks, covering my eyes, filling my nose with the scents... I lost it hard. I gripped his hips and bucked like a beast, gritting my teeth and snarling as I unloaded hard into my dad's guts. I felt his body bucking and clenching against me as his own orgasm blasted through him as well, each shot coinciding with an incredible clench around my dick which just ratcheted me up even further!
God I don't think I've ever came that hard, losing track of the number of shots and just lost in the bliss of coital contact with my dad.
I felt my dad's soles rubbing, scrubbing against my cheeks as the pleasure he was being assaulted with caused his muscles to lock and flex, no doubt making my face-fur stick up at weird angles with the sweat of exertion and lust on both of us, but fuck, I fucking loved it, every fucking second of it.
Eventually both of us came down, panting, sweating, and utterly and completely spent. Usually it takes us two or three rounds to manage to run ourselves dry, but both of us had emptied the tanks. 
I blinked as I felt something splat on my shoulder and looked up. Oh... oh fuck, that's hot. My dad came so hard, hands free, that his load had hit the ceiling above. And it was a doozy of a load, too. But a great deal ended up on my ol' man too. He was laying there, panting, shivering, basking in the glorious feeling of what getting fucked by a champ felt like. Finally the shoe was on the other foot, I got to show him what it's like!
I leaned down and started licking up the mess from his belly, his check, his neck and face, making my ol' man groan and squirm. It was adorable seeing him that sensitive and I made sure to coax that out as long as I possibly could. 
When at last he was as clean as I could make him, I nuzzled up under my dad's chin and hugged my ol' man tightly, sighing happily. "Best birthday gift ever."
Dad smiled and gave my forehead a kiss, wrapping his arms around me. "Glad you enjoyed, son. Happy birthday, Car."
Cleanup was quick if not particularly easy, we needed to use both of dad's socks and all the napkins he'd stashed to manage and even then, both of us stunk of cum and sex.
We slipped out of the restaurant quickly so the waitress wouldn't see us and were on our way home in short order.
Instead of showering like I knew dad wanted to, I instead pulled him into the living room, pulling his clothes off and shucking my own. He looked at me strangely, wondering what I was wanting to do. I gave him a push onto the couch and climbed on myself. Instead of mounting him, riding him, doing any number of other things... I just laid against my dad, cheek on his chest.
Of course I rubbed my feet against his, making our bangles jingle, but I wasn't being obscene, I was just being... affectionate. 
I heard him rumbling quietly as he rubbed my back and shoulders, rubbing against my own feet too. "Haven't done this since you were knee-height, Car."
I smiled and rubbed at his belly. "I was feeling it tonight." I looked up and dad looked at me. "I really do love you, dad. You're the best I could ever hope for. I'm glad we can do stuff like that, and just be... family." I squeezed gently, resting my cheek against his chest again. "Just wanted to tell you that."
Dad gave my forehead another kiss and hugged me right back. "I love you too, Car. Always. Happy birthday, Car."
I closed my eyes and fell asleep, snuggled up against my dad, enveloped in his arms and scent, and feeling like the luckiest bunny in the damn world.
