The sun bore its rays mercilessly upon you as you walked along the beach’s shore.  To your left were the boundless ocean and the horizon.  To your right was the dark, dense tropical forest of the island.  It had been 3 days since you had washed upon this shore from escaping from the clutches of modern day pirates during a storm.  Based on a useful amount of survival skills you acquired from Discovery channel and innawoods threads on /k/, you had done well for yourself given the circumstances.
 
You had a solid shelter set up 30 feet behind you in the form of a simple but sturdy tent with a constant fire signal as well as an easy to find food source in the identifiable fruits within the forest.  Today, however, you wanted meat.  With a spear in hand you were going to dive about 10 feet under to catch some lobster, if they were even here.  You only had to swim out about 20 feet before you were surrounded by coral reefs and diverse, underwater fauna.  
 
You took in a deep breath and exhaled as you submerged under the water.  You checked various nooks and crannies to find the telltale signs of antennae sticking out.  You constantly searched until you had to resurface for air, completing the cycle numerous times until you found yourself in a coral ring.  This should be where a lobster would be, if there were any.  As you descended into the center and began to look for any future meals, you noticed that the fish that had curiously circled close to you had started to leave… in unison.  What?  Whatever, you were way too focused to care anyways.  
 
Your dive suddenly became fruitful as you saw an unsuspecting pair of antennae poking out from under a rock.  You readied your spear and moved in closer to close in on your tasty meal.  The securing blow was interrupted, however, by the feeling of a finger tapping your back.  You swerved around as fast as you could underwater to be greeted with no view on the perpetrator.  You kept looking around, scanning in front of you but you couldn’t find any source of the tap.  As your head turning slowed, you felt yet another tap, this time directly on your spine.  Letting out what little air you had left in a gasp, you still couldn’t tell what was going on.  
 
Thoroughly spooked, you immediately decided that it’d be best if you went back to shore.  You quickly resurfaced and began to swim back, exhausted, frustrated, and mystified at what had happened.  You only made it about 5 feet, though, when you were suddenly blindsided by a tackle.  You instinctively screamed, which unfortunately caused water to begin filling you windpipe as you were dragged underwater.  You struggled in vain in your assailant’s bear hug and your vision began to darken.  ‘Oh God, am I going to die like this?’  You escaped some shitty pirates, almost drowned during some biblical storm and washed up on the island for this?  You felt like you could do nothing but brood in your final moments like some angst-filled middle schooler.
 
That was, until you felt a bite on your left forearm.  Your mind registered that it had happened but didn’t send any signs of agony.  No pain, no shock, only the greatest amount of indignity.  You’re not some fucking piece of food, are you?  Your defiance was renewed and you aimed a punch at where you guessed your opponent’s head was.  You repeatedly struck against what felt like a nose for what seemed like an eternity until you felt the death embrace loosen up.  The teeth, however, stayed in place.  Running out of options, time, and patience, you decided to fight fire with fire.  You leaned in and brought you teeth upon your opponent’s nose, causing what you thought was a yelp before you felt the teeth detach.
 
With your bloodstream being more adrenaline than blood right now, you shot towards the surface and made a beeline for the shore.  Moments after your escape you heard more splashing right behind you.  The added pressure of still having your pursuer made you swim like an Olympic champion, causing you to shoot onto shore and still flail your arms even when you were fully landside.  As you got up on all fours, you began to empty yourself of the sea water you had just swallowed just moments ago and could only fall to your side when you were done, your body feeling like it had used up a lifetime’s worth of stamina and vitality.
 
As you weakly raised your head to view the shoreline, you saw a treacherous and ominous fin sticking out and pacing back and forth before dipping below the water’s surface.  When you seemed to be in the clear, you couldn’t help but cry tears of joy while laughing, thanking whatever deity, holy or otherwise, had helped you.  That was until you heard a loud splash coming from the shoreline.  As you shot your eyes open, your attacker had breached the water and was airborne, flying right at you.
 
You sprang to your feet, which supported you as well as columns of jelly would have, and prepared to brawl once more.  You were lucky this time, however, because she only landed a few feet from the water and there was still a good amount of distance between the two of you.  You both stared dumbly at each other, unsure of the situation.  Her face was frozen in fear and embarrassment of her insufficient jump as her mouth hung awkwardly agape.  You immediately fell on your ass as your heart reconsidered if it even should continue to beat if stuff like this was going to keep happening.  
 
As your acquaintance lay there and struggled to move, you finally got a good look at her.  She was obviously a shark girl, but a feral one since she attacked you out of the blue.  Where human legs would be, a single vertical tail was there instead with a dorsal fin right above her buttocks.  Her torso was just like a human’s except for the sets of gills on either side next to her breasts.  She had bleached white hair, which was kept short and only extended to the tops of her pointed and scarred ears.  Staring into her still shocked and bleeding face, you could see that she had grey eyes and an extremely sharp set of teeth, as well as the bite mark you had left on her nose.  As for her skin, she had the coloration of a Great White Shark, as the skin above the line of her nose was a dusky grey and the skin below was a snow white like some exotic tan line.
 
Your evaluation of her features was cut short when she began to sputter and make choking sounds.  You could see that her gill slits were flapping erratically, trying to filter water that was not there.  This continued for 20 seconds before she ceased moving.  You made a careful approach to her seemingly incapacitated body.  After giving it a few prods with a stick to confirm your safety, you weighed your options.  You could always eat her.  After all, she tried to eat you and denied your meal of lobster.  That does sound rather appealing… but could you do it?  Even with all the exotic additions, she still looks like a girl.  You couldn’t tell if it was from the blood loss of the bite wound that you had yet to attend to or that you were stupid, or both, but you decided there that it’d be better to help her out.  
 
You unceremoniously rolled her into the water until she was fully submerged.  Retreating back to the shore, you kept an eye on her dorsal fin.  After a few moments, the fin began to zip across the water before retreating under the water.  As you were about to make it back to camp, you saw her eyes inquisitively peek out of the water and stare at you, blowing bubbles in front of her.  She quickly receded and left.  Letting out one last shudder, you made your way back to your camp to treat you wounds and rest, waiting until tomorrow to do anything else.  God, lobsters were not worth this amount of trouble.  
 
Today was a new day, and hopefully things weren’t going to repeat themselves.  Instead of going for lobsters today, you merely had a simple rod and hook and planned to get some fish.  This was a lot more peaceful, as you were perfectly safe on the shore and you could eat some gathered fruit while you waited.  You almost felt like you were relaxed.  You sat there for a peaceful while until you felt a gentle nibble at the end of the line.  Waiting until you could set the hook, you gave a solid yank and began to pull in the line.  Seeing a rather plump fish on the end of the line, you began to salivate.  Just as the fish was barely out of arm’s reach, however, your ‘friend’ from yesterday came in from the side and made it disappear with her jaws.
 
As she treaded water and gave a triumphant smile to you, you stood there, face stoic with a single tear running down your eye.  Immediately afterwards you let out a staggering yell, causing all the birds in the forest behind you to flee in terror.  Still treading water but now covering her ears from your scream, she began to protest.
 
“Geez, man, what the hell?  It’s only a fish.”
“Don’t fucking talk me to me, bitch!”
“I have a name you know.  It’s- hey, wait!”
You weren’t dealing with this right now.  You started to head back to camp.  Halfway there you heard a splash from the water, but before you could even begin to tell her off you had two lobsters flying towards you.  You immediately dodged the claws that were heavy with ill intent.
“Sorry!”
“You think some lobsters and an apology make up for everything?!” you yelled back.
“No, that’s my name!”  Oh, Sari.  Wait, why did you even care?  Begrudgingly picking up her offerings while gritting your teeth, you continued to your camp.  You could hear a forlorn moan behind you.
 
After roasting and eating the first lobster, you were in a much better mood than before.  Eyeing the second one as you patted your now full stomach, you judged that you wouldn’t even be able to eat it.  You recalled how you blew up at Sari and stayed mad even though she gave you such a nice meal.  Well, she did try to kill you, but whatever.  Sighing, you decided to cook up the second lobster and take it to the water’s edge.  Splashing a few times with your foot, she arrived momentarily in front of you.  This time her cheery demeanor from before was replaced with a guilty one.  With one arm holding the other behind her back, she spoke.  “Sorry about the fish.”
“And?”
“And what?”
“Are you kidding me?”  She merely looked at you inquisitively, expecting you to answer your own question.  “Christ, whatever.  Here.”  You quickly handed her the impaled cooked lobster.  “Thanks, but I’m not hungry enough to eat both.”  
She gingerly accepted your gift with a happy smile but then proceeded to question its composition.  “So… why is it darker than usual?  And warm?”  She gave it an exploratory lick before smiling again and chomping down on it.  “Whatever, it still tastes good,” she commented as she was using the stick it was on as a toothpick.  “So what’s your story?  Why’s a leggy like you doing way out here?”
 
She took a seat in the water so her gills stayed submerged and listened intently as you regaled her of you being kidnapped from a volunteering program, escaping, and washing up here.  The further you got into your story, the more excited she became, expressing her jealousy of your ‘fun filled’ life.  The You before it had all happened would have agreed, but your present self was far from content with the recent string of events.
 
In turn, you asked her to speak of herself, and why she was out here by herself.  After all, monster girls had integrated into society a few years ago pretty well so you were wondering what she was doing out here.  She grew silent for a moment before speaking.  Apparently she had been a child in the slave trade here but escaped with the help of her mother before she was sold off. Sadly, her mother couldn’t make it out as well and she wasn’t all too keen on going back to society.  You gave her your condolences and she just waved it off, smiling back at you.
 
“So where exactly are we?  Do you know?”  
“We’re off the tip of Suth Arica.”
“South Africa?”
“I don’t know. I never went to school, remember?”
Well, at least you were near a civilized part of the world now.  You inquired further, asking if people come by here often.  Your heart jumped as she said a weekly naval patrol came by and the next time it’ll come is in 2 days.  You were so happy that you fell onto your back and shouted joyfully to the skies.  When you sat back up, Sari’s face was less than happy.
“What’s up?”
“Well I’m glad you can go back home but… I’ve never had company before.  I’ve always been on my own and I was so happy when I met you.”
“So happy that you bit me?”
“Well, sharks investigate with their bite, dummy.  I haven’t seen a human in so long, I couldn’t tell for sure.  But when I bit into you, you tasted so good…” By this point she was salivating and showing off her impressive set of teeth.  “Oh when you started to fight back, oooh that was my favorite,” she cooed.  “Nothing out here can even thing about resisting, but the way you punched my nose… and then you bit it…” With that last bit, she was starting to crawl towards you, face heavy with a cute purple blush.  
Uncomfortable with the turn of events, you immediately sought to change the direction of the conversation.  “H-Hey Sari, I’m not leaving immediately, remember?  We can… hang out and stuff.”
Her face lit up, changing from passion seeking to joyous.  With her libido averted for now, you two agreed to meet up again tomorrow.
 
Around noon, you had made your way down to the beach again.  You could see Sari’s obvious and menacing fin circling about as she waited for you.  As you waved, you said, “Sorry, did you wait long?”
“Nah, I actually just got here,” she said while smiling.  You both looked over your shoulders, as you felt that someone was sighing.
“So what do you want to do?”
She extended her webbed hand out to you.  “Come on and join me!”  You stood there hesitantly as you looked down to your left forearm, reminding yourself of what happened last time you were in the water with her.  “What, I won’t bite you again, come on!”
Well you did make a promise with her.  Against better judgment, you waded out to where she was.  She took your hand without warning and started pulling you along.
 
For the next few hours, Sari gave you a tour of the surrounding reefs of the island.  She took you to areas that reminded you of ocean life specials that aired on TV.  As you passed by each one, mouth open with awe, she looked back at you and smiled, glad that you were entertained.  After a while, she suggested a game of tag.  Why not?  You chose to be ‘It’ first, so for a while you treaded water and counted, you could feel her swimming around you, confident in her speed to keep her in the game.  Once the count was over, you quickly descended into the water and waited for her taunts.  The familiar finger poke greeted you again and again until you observed a pattern for them.  As she came around you back for the next one, you quickly turned and shot your arms around her in a hug, effectively catching her off guard and in your clutches.  
 
With your arms still wrapped around her, she sprang upwards to breach the surface.  As you looked up to her, you both burst out into laughter.  She soon began blush, however, when she noticed your head was close to her bountiful bosom.  With mock embarrassment, she delivered a light smack to your already red face, prompting you to let go.  Before you could even apologize, she took your hand again and continued to pull you around the island.
 
With your final stop, you found yourself at a small little lagoon not too far from your camp.  With your previous activities taking up a good chunk of the day, the sun was setting in the horizon.  Sari’s swimming interrupted your appreciation of nature as got next to you on the beach.
“So yeah, this is my private spot.  You can already tell why I like it so much,” she said as she pointed to the already viewed sunset.  
You nodded in acknowledgement.  “Yea it’s really pretty.  Like you.”  You said that last part rather nonchalantly with a small smirk, like a joke between friends.
“R-really?”  You looked back to your companion, whose face was once again ablaze with blush.  “You really think I’m pretty?”
“Hmm?  Yea, sure I do-“ Your words were cut short as she lunged onto you and stole a kiss.  
 
While the kiss itself was light and brief, it stunned you all the same.  As she parted from your lips, she began to rip off the worn remains of your pants before you could even voice any protest.  She inquisitively and playfully began to play with your currently soft tool, running the textured skin of her fingers over its length to awaken it.  She cooed as your began to harden against your will and began to teasingly stroke your shaft.  You moaned as her grip tightened, accentuating the feeling of her denticles on your most sensitive part.  She made sure not to neglect the tip either as she constantly had a finger or two rubbing gently on your head.
 
You placed a hand on the back of her head, taking a gentle grip of her surprisingly soft, white hair.  Understanding the notion, she opened her mouth and began sucking the entirety of your cock.  You could feel the constant presence of her razor sharp teeth surrounding you, only getting close enough to lightly tap you with each point as she moved up and down, adding only pleasurable sensations.  This sensation was completely foreign to you and allowed you to build up pleasure even faster.  Hearing your moans of pleasure, she began to look into your eyes as she orally pleased you.  She intentionally slowed her pace, teasing every inch as slowly as she could before coming off your cock with a lewd *pop*.  
 
She grinned her toothy smile again as she placed her breasts around your mast and squeezed it in between them.  You almost fell backwards immediately from the sensations that were affecting you now.  This was similar to how her hand job felt, but felt so much better, as the softness of her breasts as well as the texture of her skin made such an encompassing and surrounding sleeve for you cock.  To top it all off, she began to press the tips of two of her teeth delicately onto your glans, causing you to moan as your legs shook.  She increased the pace of her breasts dancing on your cock while you could only dig your fingers into the beach sand.  Under her full denticle pleasure assault, you could only last a minute before you shot your first load onto her heaving and beautiful chest.
 
Both of you just laid there to catch your breaths.  After a few minutes, she grabbed your hands into her webbed ones and rolled onto her back with you on top of her.  She settled down a little to make sure her gills were still in the water before placing both of her hands to where her crotch would have been.  Blushing and looking away from your gaze, she spread a nearly invisible slit to reveal her beautiful pink passageway.
 
“H-Here, this is the first time I’ve been able to do this,” she said while still unable to meet your gaze.  “But… I’m really glad it’s with you.”
You gave her a light kiss before saying, “I’ll be gentle.”
You swiftly placed yourself at her now spread lips and eased yourself in.  Both of you gasped intensely as her virgin walls shuddered when they tried to accommodate your presence.  Soon you were about to breach her hymen.  As you looked to her, she merely nodded with a hazy but familiar grin on her face.  Your hips kept moving forward and you felt her virginity disappear as she winced in pain before moaning in pleasure.  When you had finally hilted, her whole body was shivering from your presence.
 
She proceeded to hang her arms from the back of your neck as you placed your hands on the ground to her sides.  Retracting your hips, you began to pump in and out of her in earnest, earning her moans and whimpers of pleasure as approval.  You felt first hand that her control of her lower body was amazing, as you felt her passageway contort in unexpected ways as she tried to milk you for all that you had.  Each ridge and fold of her womanhood gripped and pulled your manhood in every direction that it could, submitting themselves for nothing but your climax.  You could hear her excited tail make a ruckus behind you, causing large splashes and waves to form in the small lagoon.
 
You didn’t let up, making sure that each of your thrusts were angled so that your head was always directly rubbing against her walls.  Soon, your thrusts were becoming too much for her and she began to hug you tightly.  Her abdominal control also continued to surprise you, as it became harder and harder for you to pull yourself away from her.  This increased suction succeeded in increasing stimulation for both of you as she continued to moan at your mercy while your grunts became more frequent as each thrust became more pleasurable than the last.  
 
You could tell that she was getting close as her embrace around you tightened while her hot and heavy breathing was hitting your shoulder.  As you felt her walls convulse around you even more, signaling that she was finally cumming, you suddenly felt her bite down on your shoulder, sending mild shocks of pain to your brain.  Surprised by her sudden and vicious love bite, you couldn’t help but bite her back on the shoulder as you time came as well.  As you both groaned while biting each other, you pumped her wanting hole with you seed, which it greedily accepted.  
 
There was a brief pause as you two held each other in what appeared to be a death struggle.  You removed your teeth first and soon after you felt hers retract as well.  It wasn’t a very deep bite, but her teeth were tinged all the same.  She looked away, embarrassed again at her predatory instincts.  “Sorry, that must of hurt, right?”
Standing and having looked over the wound, you shook your head and smiled at her.  “It’s definitely not as bad as when we first met.  Plus, a man has to endure a little pain for his love, right?”  At your last words, she sprung up into your arms and hugged you, rubbing her nose into your neck as she laughed.  You couldn’t help but laugh along with her as you spun around with her in your arms.  Well, until she started to choke from being out of the water.
 
Hours passed and you found yourself lying under the star lit night sky.  You two were laying opposed to each other, with her lower half and torso still submerged in the tiny lagoon while you had your feet pointing towards the island.  Between your heads you were gently keeping her hand embraced with yours as she hummed a soft lullaby.  After she had finished, she cleared her throat to say, “You should go to sleep soon… the naval patrol comes pretty early in the morning.”  The melancholy in her tone was all but subtle.
“You said it was a weekly boat right?”
“Mmhm.”
“Well,” you started as you turned to her.  “I could always wait till next week.”  
 
As her face lit up, you once again saw her distinct, toothy smile as she turned to face you.
