Shark Wank

“You know, having gills isn’t fair at all.” I said to Shimmer as we pulled ourselves into the cave. My helmet lamp was the only source of light in the cave, and it cast strange shadows on the stalactites, with some of them reflecting the light back with myriad shades of colour.

“Life isn’t fair, Storm.” she said as she reached into her saddlebag and grabbing a number of glow sticks in the process. The next moment she began to break them, and with that, there was more than my lamp casting light in the room.

“Yeah, but you kept on rushing ahead,” I said with exacerbation in my voice. “I have to lug around the heavy ass scuba gear!”

“Oh, alright, maybe I shouldn’t have gotten distracted by the pretty fishes~” She said before grinning and baring her fangs. “In my defence, they looked delicious.” I rolled my eyes at that as I took off my scuba gear and left it against the wall several feet from the entrance.

I looked over at the cave opening, where our light barely penetrated. Darkness and light coming into a kind of shadowy equilibrium for the first few feet beyond. She just turned to face me.

“Last one to the scary tunnel is a rotten egg!” she said before bolting towards the entrance. I followed behind her, lighting my horn in addition to the helmet light. I really didn’t want to fall down and cut myself on the sharp floor.

“You’re insufferable.” I said to her as she easily came out ahead.

“And you’re a rotten egg~” she replied in a sing-song voice, something ponies wouldn’t expect from her with her regular vocal range.

“Pfft. I digress.” I said as I pulled myself into a good spot behind her, my helmet light illuminating her rump. The bikini she was wearing didn’t obscure much, even if she had her tail down. It was a good look on her, the sexy red fabric stretching over her voluptuous ass.

“And I digest. See that’s why we fit together.” she started saying, even as the corridor got tighter by the second. “We’re different, but like, complimentary. Like Peanut Butter & Jelly, or Yen and Yang, maybe even death and taxes.”

“That last example isn’t a good thing, those are both annoyances to most ponies.” I protested in vain.

“But like, imagine if people didn’t die and if we didn’t have like, basic stuff. Let’s be real, both of those things are good for society as a whole, just bad for individuals.” she paused and shimmied back and forth for a moment to get past a particularly tight spot. I had to suck in my barrel, and work a bit harder to get past the same spot. She was bigger than me, but also, a lot more flexible.

“That’s a...really analytical way of looking at things.” I said as I managed to clear the tight spot.

“Whoa-” I heard Shimmer say as she stopped moving forward, I barely caught myself before running into her. Her tail flicked from side to side, and I got a good glimpse of her nethers.

“What is it?” I asked as I tried to look around her. The moment I got a good look, my jaw dropped…

---===*===---

One week earlier:

“Tidal Surge! Get over here!” Shimmer nearly yelled as she looked at her kid’s room. The kid bounced into the room in the way that only a child could.

“What is it mom?” Tidal asked with the hint of a smile on her muzzle. Her fin shifted on her back unconsciously.

“Why’d you break your toy?” Shimmer asked with a glance towards the small pile of eviscerated toy.

“I wanted to.” she said with no apprehension.

“That’s not a good reason to destroy things...” Shimmer said with annoyance clear in her voice.

“I was angry.” said simply.

“Why were you angry?” Shimmer asked.

“Some ponies called me names...” Tidal replied ruefully. “They called me soup and fin-flank.”

“They’re just jealous of you, Tidal.” Shimmer said after a moment’s thought. “Regular ponies are a dime a dozen, but you aren’t. You’ll never have to bother with the dentist because you have an infinite supply of new teeth. You’re going to grow up to be as big as most earth pony stallions, and you’ll be able to breathe underwater-”

“I know all that Mom!” the filly said before stomping a hoof into the floor. “Nopony wants to play with the weird filly with fins and sharp teeth.”

Shimmer didn’t say a thing to that, she just stepped forward and wrapped a foreleg around her child. Tidal Surge stopped pouting, instead, she pushed into the embrace, before pressing her muzzle against her mother’s leg and barrel. For a moment they stayed like that before the sounds of quiet sobbing reached Shimmer’s ears. Tears ran down her skin like petite raindrops.

“It’s okay sweetie...” Shimmer said in a quiet voice. Shark ponies could be loud and were loud a lot, but they had quiet moments too.

“I don’t want you to leave Mom!” The filly said as she pulled back from the embrace, her plaintive voice tensing up her mother's heartstrings.

“Petal will be here,” Shimmer said instantly. “And I know she spoils you.”

“I love Grandma, but she isn’t you, she doesn’t understand like you!” Tidal said before pouting again, and wrapping a little foreleg around her mother’s leg. “I’m not gonna let go!”

“Oh no!” Shimmer said with false concern. “I guess I’ll have to take you shopping with me, and to the Salon, even to the stinky cheese store!” The moment she mentioned the cheese store, the already weakening grip on her leg fell away.

“That’s not fair Mom,” Tidal Surge protested as her mother pulled her closer.

“Just ask Petal for sushi and Ice cream.” Shimmer said quietly, before fiddling with her kid’s mane.

“Okay...” the filly said reluctantly. “You better bring me back something cool!”

“I promise.” Shimmer said tenderly. She let go of her kid.

“Just, give it time, eventually, you’ll be the coolest pony anyone knows,” Shimmer said before bending down and leaving a kiss on her forehead. “That’s how I got your dad.”

“Gross!” Tidal said at the twin irritations of the kiss and the mention of how her parents met.

“Fair enough,” Shimmer said before forcing a more stern expression onto her face. “Now, clean up your toy, alright?”

“Alright...” Tidal replied after a moment’s pout.

“Well, I have a boat to catch.” Shimmer said before hugging her child again.

“Don’t eat any of the crew mom!” Tidal Surge said with a laugh.

“I’ll keep that in mind.” Shimmer said as she walked back towards her room, and her luggage.

---===*===---

We trotted into the chamber, a chamber filled with effervescent light emanating from crystals embedded in the wall. It sparkled like a field of multicoloured stars. I was blown away. Maybe this cavern hadn’t been explored before. Shimmer turned to face me.

“Bingo.” she said with a triumphant expression on her face. Her long teeth shown heavily in the look.

“Were you looking for glowing crystals?” I asked, slightly unnerved by the obviously magical light pouring from them.

“No, just something cool in general, but these certainly look cool.” Shimmer said before walking over to one of the shimmering crystals. She touched it with a hoof, and for a moment I was worried it had done something to her. “Damn, I was hoping that I would like, turn into a crystal shark or something.”

“You’re ridiculous.” I said as I shook my head at my wife. She just smiled at me before searching through her pack. In a moment she had a rock hammer in her hooves, and before I had time to stop her she had brought the steelhead of the tool into one of the smaller outcroppings of crystal. “What are you doing?!” I yelled as I watched the small crystal snap and fall into her hoof on the way down.

“Tidal wanted a souvenir.” she said flatly, before carefully wrapping the fragment in a cloth and stowing it in her bag. “I promised her something cool.”

“Hey, Come on. Let’s leave this place as we found it.” I paused and let out a deep breath. “Well, more or less as we found it.”

“Okay, you absolutely soaked blanket.” she said before sticking her tongue out at me. The next thing she did was a slow trot over to me, her tail flicking from side to side slowly, drawing my eyes toward the curve of her rump. I backed up a step before realizing what she planned to do in this cavern.

“C’ mon, we should probably take some pictures and head back.” I tried to reason with her. It didn’t work. The second after I spoke, she was on me, and her mouth was pressed against mine. Her tongue bypassed my lips, slipping into my muzzle and dragging my lips apart. I moaned unconsciously, even as she continued to push me backwards. I ended up nearly vertical before she grasped my barrel with her forelegs and slowly dropped me onto my back. The water smoothed cavern floor was cold against my back, however, that wasn’t the sensation that filled my conscious mind.

“Oh we’re gonna take pictures alright~” Shimmer said before grasping my hind legs and pulling them apart. My half-hard member was already poking up into the air. She grinned at the sight. Without waiting for any kind of approval or anything as quaint as a queue from me she opened her muzzle and brought it down onto my mottled member. I moaned instantly, as I enjoyed the rare treat. She mostly avoided blowing me because it tired out her jaw. But I loved them. Watching her predatory gaze sweep over me, feeling the smallest hint of sharp teeth over my cock.

“Aaah!” I moaned as my cock twitched and grew to fill her muzzle. Her tail continued to flick behind her, faster now. Just then, she slipped a forehoof underneath my ballsack and lifting it up, before letting my cock fall out of her muzzle. The next second she opened her mouth even wider and slipped my right testicle into her muzzle. I yelped at the exotic feeling, the warmth and wetness around my sensitive nuts. “Jeez. B-Be careful...” I managed to get out before she slipped that testicle out of her mouth and moved onto the next one. In response, she let one of her blunter teeth graze the skin lightly. I gulped audibly, before resting a hoof on her shoulder. She mewled at the contact, before shaking her rump behind her.

Even I couldn’t miss a signal like that. My horn lit up and lifted her tail up and out of the way. She let out a guttural moan as I slipped my tendril of magic into her marehood, stretching it out. The moan travelled up her throat and into her muzzle. It felt amazing on my balls. I took a deep breath as she left my now thoroughly soaked balls alone. Shimmer dropped her head even further down, leaving kisses and small bites on my inner thighs.

She was getting really into it as I played with her marehood using my magic. It was enough for me to do something drastic, I pulled out the waterproof camera from my bag, before quietly moving it over to my stomach. I removed the lens cap, before aiming at my wife, who was busy licking at one of her love bites.

Click!

Shimmer looked up just as the flash went off, blinding her for the second. Then she grinned as she looked up. I watched with bated breath as she swallowed my cock again, redoubling her efforts at blowing me, and nipping my base a little when she reached it. My cock throbbed in her tight throat. She must have felt the throb, because a moment later she pulled off of my cock before climbing up on top of me. A moment later, she lifted herself up as she aimed her tight cunt at my cock.

“Aaaah!” I half moaned, half yelled as I felt her warm depths stretch around me. She smiled and moved her mouth down to my neck, before biting it just hard enough to cause pain. I held onto her tightly as she began to bounce up and down on my cock, driving me inside her deeply with every bounce. Her own grunts followed soon after. The husky sound of her moans, and my own mixed in the cavern, a cavern that before had only felt the sound of water slowly crawling up the inside with the tides.

“You like that? Me riding your cock?~” Shimmer asked with that toothy grin plastered across her face. I responded by meeting her next downstroke with a potent thrust, and smacking her bi-coloured flanks with my hoof. Shimmer moaned at the treatment, before backing herself up and grasping one of my forelegs with her own. She took it in her hooves and moved it down to her teats. I took that moment to rub them, revelling in the memories of when they had been even bigger. Back when Tidal Surge had been nursing. Regardless, they were bigger now than before she had gotten pregnant…

“I love it... I love it when you ride me~” I said breathlessly as I strained my core muscles, as she squeezed my cock. I needed to keep myself in check.

“Really? Well, I’m coming into heat soon...” she said huskily. “Maybe I’m already in it~”

“That’s really hot...” I replied as she bucked her hips into mine, my cock twitching and pulsing with need inside her. “Is that why you wanted to come here?”

“The cave no,” she said before licking her lips and grinding her hips against mine. My cock was nearly at her cervix from this angle, a fact she was very much into. “The vacation, well, I would like to come home with a belly full of a pup~”

“I-I can help with that~” I said as I felt her body start to lock up on me as she realized how close she was to being filled.

“Then do it!” She yelled before thrusting down on me as hard as she could. It was enough to push me over the edge, and with a grunt I stopped clenching. A moment later, a deep pulse from inside me signified my finishing. The first pulse of cum exploded inside her, driving deep into her. “Ah...” she moaned as she felt the warmth and thickness of my seed deep inside her.

The next pulse was just as strong and it sent seed up between the narrow confines of her filled pussy. We were going to leave at least something behind in this cave. My third shot was a little weaker than the first, but by that point I didn’t care. My wife wanted my cum inside her, and my endorphins were flooding my brain even as Shimmer bent down and kissed me.

I looked up at her a few moments later, before tilting my head further forward. Underneath her was an absolute load of seed, slowing expanding in a pool around us. The dark rock, mostly lit by the crystals buried in the wall, was a massive contrast to the white cum covering it. Without meaning to, she slipped off of my deflated member, before falling onto my chest.

“I love you.” she said quietly. I clutched her back, and gently rubbed her fin.

“I love you too, hun.” I replied a second later. Our faces were inches from one another. “And I’d love to see your tits get big again~”

“I knew you were into that!” She said with a laugh. “Why didn’t you tell me when I had big tits a while back?”

“Well Excuuuuse me, Princess, I wasn’t sure if you were into it.” I said sheepishly as the afterglow washed over me. The afterglow was a time for cuddling, kissing, and radical honesty.

“Well, I am~” She said in a neutral voice. “We’re gonna have a lot of fun with my tits when they grow again. How does a titty fuck sound?”

“Really, really good...” I replied as I felt my cock wake up again. I groaned at the feeling of her warm body against my growing member.

“You know, you’re a lot of things, but you have a hell of a refractory period.” Shimmer said with a smile as she felt my cock twitch and press against her ass. “You wanna mount me, really breed me?”

“Yes, Ma’am~” I replied with an exaggerated bravado. She leaned over and got to her hooves, and I struggled to move after that hard fuck we had just partaken in. “I’m gonna breed you so hard!” I nearly yelled as I got to my hooves and watched as Shimmer moved her tail aside. Her pussy winked out another load of cum as I watched. She wasn’t just leading me on-

“C’mon already, I bet your scuba tank is leaking air~” she said loudly before slapping her flank hard enough to get even her toned ass jiggling.

“Alright then~” I said as I trotted over there, before lifting myself up and over her. My cock was already mostly hard, and hard enough for sure to penetrate her tight pussy. I pushed forward until I felt our flanks touch, the warmth and cum soaked inside of her sloppy pussy felt amazing around my cock. I slid back until my head was barely inside her tunnel, before pushing back hard! My pistoning drove a moan out of her throat, and she growled as I pulled back.

“Harder!” She yelled as I pushed into her again. A moment later, I bent my head forward and bit her neck. She howled and moaned as my teeth almost broke skin. Shimmer tightened and squeezed at my member as I bit her. I threw my head back, pulling her skin back for half a second before releasing it. The tightness only grew, as the pain spurred her on. I knew from biology and some very niche porn that shark ponies were into roughness when they bred.

“Harder?~” I asked with a shit eating grin on my face. She turned her head to look at me before nodding heavily. I took that a queue. My hips bucked into her, our sweaty bodies pushing and touching all over. The contact was nice, but I knew what she wanted-

“Oooh...” She moaned hard as I nipped her ear. I ground the sensitive cartilage between my teeth, even as I fucked her as hard as my strong legs could manage. Already, I was putting most of my weight on her legs. They were tough, she was tough, and I was already pulsing and throbbing inside her tight pussy. I let go of her ear, before moving to her other ear, doing the same thing to it. All the while, she slammed her hips back into mine with each thrust. It got harder for her to do so as I lost my rhythm in fits and starts, before regaining it for a moment, and then losing it again as my bestial side took over.

“M-Momma likes~” she said loudly as I stopped giving a shit about Rhythm or any other trapping of civilized sex. I just slammed into her pussy as fast as I could, feeling her tighten and loosen in time with my bites and nips. There would be evidence on her neck-

“Daddy does too~” I moaned in reply as I felt her lock up beneath me, her legs shaking in pleasure and strain. I groaned loudly as I felt her warm body against mine. We were bonded in only the way a loving couple could be. Intimacy, cuddling, dates and all that other stuff was great and fine, but nothing else could compare to the dirty pleasure of fucking hard.

“Oooh, are we into that now?” she said with a laugh as I blushed in spite of myself, in spite of the pressure building up in my gut, in spite of the increasing sensitivity of my length inside her.

“Y-You said mommy first!” I said with a groan as I pumped into her deeply once again, my forelegs holding onto with all the muscle strength they could muster. I didn’t want the feeling to end, I didn’t want to stop feeling the tight, muscular, predatory body of my lover.

“I did~” she said with a moan before winding up her tail and smacking the heavy appendage against my ass. I moaned from that oddest of moves she could pull off. I loved it!

“I guess I like it…..” I replied as I felt my orgasm come closer, and it was a kind of high that even a good amount of control couldn’t subdue. “Do you?”

“Yes, Daddy!” She moaned out as her body clenched around me again, my last load of sticky seed being pumped out of her by the tightness and the lack of space inside of her.

“Nnnnn…..I’m gonna….!” I yelled out as I slammed home one last time. The feeling of her walls convulsing around me was enough to push me over the edge for the second time. My cock throbbed and my seed spilled into her. Without a warning she fell forward as her forelegs collapsed from the pleasure and the combined weight of two ponies. It didn’t stop my cock from filling her up again, seeding her for the second time on this trip, but definitely not the last…

Moments later, she rolled the two of us onto my back. Where I continued to hold onto her tightly, and gently rubbing her stomach and teats. The two of us almost took a nap, but indeed, sleeping in a strange cave that may or may not have had a supply of fresh air- it wasn’t the best of ideas…

So we left the cave after taking several more pictures and documenting the route to it.

We were explorers after all.

---===*===---

“Mom, Dad!” Tidal Surge said as we entered the living room. She ran over to us before giving the both of us a cute little hug. A moment later, Petal Breeze came out of the kitchen before smiling at the two of us.

“How was your trip?” She asked in that matronly way that only a grandmother could.

“Pretty good, pretty relaxing.” I said as I watched Petal smile broadly. “How was she Mom?” My words were placid, but I was marginally afraid my daughter had been a little tyrant.

“She has quite the appetite, but other than that, she was a perfect child.” Petal Breeze said, smiling, before walking over to the three of us. She ran a hoof down Tidal Surge’s messy mane. The filly pressed back against the older pony. Clearly they had grown closer during our absence. That made me smile.

“Hey, I told you I’d get you a souvenir, didn’t I?” Shimmer said loudly, with that broad grin on her face.

Without waiting for a reply, she reached into her bag and pulled out that piece of crystal we had gotten from the cave, except it was polished into a shape pretty close to a shark’s tooth. The moment that Tidal’s eyes laid upon it, her eyelids shot open and she started charging towards her mother.

“I-Is that really mine?” She asked as she ran towards her mother. Shimmer pushed a hoof out in front of her and pressed into the filly shark’s shoulder. She stopped and looked up at her mom and the shiny necklace.

“I said I’d get you something cool, didn’t I?” Shimmer said with a laugh. I rolled my eyes before watching as the gift was passed onto the shark filly.

“It’s so cool! Thanks Mom!” Tidal said before grasping it with a hoof, feeling the smooth glowing red surface. “Will it make me into a crystal pony if I wear it?”

“Unfortunately, not.” Shimmer said before turning to me and sticking her tongue out. Like mother, like daughter I guess.

“Does anyone want to go out and eat?” Petal Breeze said after watching the little fillies smile dip a little.

“I’m starving.” I said as I looked at the three most important girls in my life. And then with a smile, maybe there’d be a fourth soon…

Shimmer met my smile with one of her own, before looking back at Petal Breeze. “Fish restaurant?”

“Do we ever go anywhere else?” she said with a note of mock resignation.

“Yay!” Tidal Surge said happily before running over to me and giving me another hug. “Daddy, what are you gonna eat there?”

“Something vegetarian.” I said to which the other adults laughed.

“What’s a vegetarian?” Tidal Surge asked.

“I’ll tell you when you’re older, sweetheart.” Shimmer said with a laugh as her daughter pouted…

The End.
