A fishy surprise.

Before you have a chance to take in what you're seeing, a blue-ish gray limb breaks the surface of the water and grabs your arm with immense strength. You're quickly pulled under into the murky depths without a sound. Your eyes are blurry and your lungs feel tight as you weren't prepared to be submerged so quickly. Although you can't see, you feel yourself moving underwater, being pulled by the same **** that has your arm right now. You can barely make out a gray blob in the darkness that moves with grace in front of you, or at least it would if it wasn't currently dragging you along for the ride.

You brain rushes to make sense of what's happening, but your lungs have no more air to give it for that end. You cough air bubbles into the water as liquid fills your stomach and lungs, which causes the unknown creature to take notice and stop. Your lungs and brain now feel like they're being crushed, your mind is going too fast to focus on anything in its helpless state to try and figure out something to save you, and you can't help but feel sorry that Rits won't know what happened to you in your final seconds.

The last thing you expect is something soft and smooth lips to be kissing your lips, but that's what's happening now. The creature is right in front of your face, its features a little more clear, but your brain isn't concerned enough with the identity of your attacker to really notice anyway, as it's still trying to focus on not drowning first.

"A man..."

You're also surprised to hear a voice underwater, as clear as if you were still on land. A sultry female voice, at that.

"Sorry, I forgot you die in water. Breathe."

You notice a few things at once, but you're slow to really take it all in.

First, you can breathe. That's kinda the most important piece of info here. Your lungs instinctively take in a deep breath of water as if it were the most natural thing in the world. Like you were born able to do it.

Second, you're not currently being crushed under the pressure of the depths. You feel light and maneuverable, just like you were floating instead of swimming.

Third, you can see clearly. The water does not blur your vision any longer, although it doesn't magically clear the murky water. It's more like you're wearing goggles now.

With that vision, you can also make out the features of the thing that took you, and seemingly gave you these abilities. The woman, that is.

Just like Rits and the harpies, she seems to be a half-human of sorts. Her hair is medium length, not as long as Rits, but about what a normal human woman would have, which is blue-ish in color and falls in smooth locks around her face and down to her back. Her eyes are sharp and piercing, the eyes of a true predator, although you don't sense any hostility. Her mouth is plump like you felt, although you can see hints of very sharp, pointed teeth behind them. Both rows look to be filled with nothing but pristine, sharp razor-like teeth. Her face is relatively human besides that and her ears, which seem to be triangular like Rits' ears, but more suited for aquatic living. Her torso is built firm and athletic, with a toned belly and visible muscles as a byproduct of her swimmer lifestyle. What look like shark fins poke out from along the length of her forearms. Speaking of, her entire lower body bares a striking resemblance to a shark, with a dorsal fin sticking out from her rear, two pectoral fins on her waist, and pelvic fins lower down on her tail, which terminates in a massive tail fin with upper and lower halves. Most of the shark skin is colored dark blue / gray, with her underbelly being off-white just like Rits', although all the skin on her human parts, including her face and breasts, is that unnaturally pale color as well. Her breasts are perky, a more average size to allow for hydrodynamic speed, a mirror to the harpies' aerodynamic breasts. All in all, she's a stunning display of a shark's chilling grace and a human woman's youthful beauty. She reminds you of old folk tales of mermaids you used to read about, but with an apex predator twist.

Now that you think about it, maybe all those children's stories of monsters had a grain of truth in them.

Before you can try and say anything to her, she brings her lips to yours again, kissing you deeply as you she puts your hands on her body. Her skin feels weirdly like sandpaper to the touch, but only if you go against the grain by stroking upwards, instead of downwards towards her tail.

"You're mine, human. Time to mate."

She's very blunt in her words, but you guess all monster girls have this mentality in the end, no matter how outwardly cordial their personality is.

Your dick is already hard from her kisses earlier, as she removes your pants and exposes your crotch to the open water. She smiles with a toothy grin, intimidating razor-sharp teeth showing. You hope she doesn't plan on a blowjob, for your sake.

Your fears are eased when she takes you by the hips and brings you towards her human vagina, ready to take her first man. She wastes no time in inserting your manhood into her, a low groan escaping her throat. Just like her outsides, her pussy is smooth as well as being well-lubricated, although it's much cooler than the burning-hot feeling of Rits' sex, it's by no means unenjoyable. The zero gravity sensation of sex underwater is new but exciting. You both seem to glide effortlessly into one another, as if the water provided no resistance. The unnamed mershark (you figure that's as good a name as any for her right now) is enjoying her first experience, even if she's a bit rough around the edges with her only mate. Aside from the occasional small laceration from contact with her skin, she is extremely mindful that she's bigger and stronger than you, and takes care not to bite or scratch you with any of her serrated teeth or claws, nor put too much **** on you with her massive body. She's a gentle giant, all things considered. She may be a perfect killing machine, but you wouldn't know it by her gentle lovemaking.

Thrusting deeper into her marine pussy, you feel the soft folds of her vaginal walls giving way, her need to become pregnant with a human's seed and then give birth to more monsters overwhelming any discomfort she might've felt for her first time. While her eyes are sharp, her expression reveals her pleasure, an endured face looking back at yours when she opens her eyes. She takes you in for yet another deep kiss, her instincts telling her to get as close as possible with her mate to ensure she is knocked up.

It's not long now before you feel your climax approaching, taking the time beforehand to warn your partner, although by this point you don't think there's a monster girl out there that doesn't want to get pregnant by default.

"I'm... gonna... cum..."

You can speak as though you were just talking normally, but curiously no air bubbles come out of your throat.

"Cum inside. Don't worry..."

She trails off, but you don't have time to think before you're shooting your load inside her, pulling her hips into yours in a loving embrace. She lets out a moan as you break her concentration and she cums alongside you, shuddering in her orgasm. You pump yet another load into the monster girl's womb, becoming the father to yet another family of monsters. You've lost track already of how many times you've cum in, on, or around a monster girl so far on this journey, and you suspect that number will only increase with time.

You both pant for air (or water, rather), as she still holds you close. She speaks up again.

"It's done, human. But..."

"Hm?"

"... it will be hard to find food now... but what is there to do...?"

You figure it's about time you actually talk to this girl now, as the number of questions you have is only getting bigger.

She continues talking to herself, more so than towards you.

"The water is big, but not big enough for a family..."

She appears deeply troubled by whatever she's talking about, so you try to pry more information out of her.

"What is your name?"

She seems a bit startled by your voice, but answers as best she can.

"My... name? I think... Mar-y?"

She seems to have trouble coming up with her own name. It sounds foreign even to her, which just brings up more questions.

Before you can start speaking, you hear a familiar voice from above the surface. It's a concerned female voice yelling your name.

"John!? Where are you!?"

Rits has noticed your absence and is obviously distraught over it. You move towards the surface to go find her, but Mary seems to have other plans.

"Human, you can't leav-"

She grabs your arm to stop you, but an electric shock hits both of you at the second she makes contact. She looks surprised and lets go, both of you stunned for a moment.

"Oh..."

You try to think about what that means, but she seems to let you go on your way for now, so you focus only on getting back to Rits.

You're able to swim up and breach the surface, taking in the cool air as the rain has stopped but clouds still hang overhead. You probably should've considered if the ability to breathe underwater would've overwritten your ability to breathe oxygen, but there's a lot to think about right now. Rits is slithering back and forth on the shoreline and yelling your name.

You start swimming over and yell Rits' name as her head spins around to see you currently emerging from the lake. She seems incredibly relieved to see you again, a fact that's evident as she lifts you out with her tail and brings you in for tight hug, fawning over you like she just found her lost child.

"Oh, John! I was so worried! I turned around and you were gone, and then I couldn't find you, and I was so afraid of being alone but I'm a terrible swimmer so I can't-"

"It's alright, Rits! I'm fine. Don't worry. I'm not leaving you any time soon."

Rits is shaken, but calmed by your presence in her arms.

"Aw, Darling!"

She nuzzles her face into yours as you have **** but to dangle in her arms like a teddy bear being hugged by a child.

Rits suddenly seems distracted and looks at something behind you, in the water. She quickly moves you behind her, still held in her strong tail, as she readies a fighting stance with her claws in front of her.

"Did you take him!"

You see she's talking to Mary, who followed you here and is treading water as closely as she can to the shore.

"He's mine now. Give him back."

"Give him back!? He's my husband! Just try coming up here and taking him!"

"Hm...

… can't."

Mary reminds you of Simi in the way that both are very succinct in their words, but you get the feeling that Simi just didn't have much to say, whereas Mary literally doesn't have the vocabulary to speak elongated sentences with.

"That's what I thought! Now get lost!"

"Can't do that. I need a man."

"Well, that's not my problem. Go find another."

"Nope. First man in a long time. Maybe the last one, too."

You really want to ask Mary some questions, but that's kind of hard given where you are right now.

"Uh, Rits? Can you let me down so I can speak to her?"

Rits thinks for a second before setting you down, still on her guard.

"Alright, but don't get too close, Darling. Who knows what tricks she'll pull."

Rits clearly doesn't like her, but she trusts you enough to speak with Mary.

You walk up to the water with Mary's attention on you now.

"Mary, can I ask you some questions?"

"Quest-ions? I guess, human."

"It's kind of hard to speak with you all the way out there, can you come closer?"

"Hm. Fine."

She swims closer to shore, eventually beaching herself on the sand and propping her body up with her arms. She must not really be built for land since she has to awkwardly sit up in a lying position to speak, but it'll work. You squat down on your knees to get closer to eye-level with her.

"Mary, what are you doing here? Were you born in this lake?"

"No, don't belong. Too big, too hungry. Home is big. Much bigger than the... 'lake'...?"

"Home?"

What body of water could've been home to a mershark?

"Are you talking about the ocean?"

"Ocean. Big water. For as far as you can see. Open sky. Lots of fish. Lots of us, too. My family..."

Her face grows sad as she seems to remember her original home and her family, in the vast seas beyond this small lake.

"So why are you here, Mary?"

"... hard to remember. Too young to know. The sky was dark. Water was strong, way too strong for us. Sisters got split up, and mom too. I was pulled away by the waves. Everything goes dark. Last thing I remember, I wake up here. No sisters. No mother."

Damn. Her family must've got caught in a hurricane when she was very young. She got separated and a tidal wave carried her inland.

Rits is deeply affected by her story.

"That's... so sad... I know how you feel."

"I want to go back. More than anything. But I can't survive long where you come from, on land. Too dangerous to look."

By the fact that she's been talking to you on land and breathing air so far, you can assume she can survive for a bit of time out of water, but eventually she's gonna need to submerge herself again and rehydrate her body. It would be far too risky to crawl on land and look for the ocean on such a time limit.

Rits clearly wants to help, but doesn't know what she can do.

"I wish I could get you back to your home, but... I haven't a clue where it is either."

So you need to find the ocean if you want to help this poor girl. You can just pick a direction and walk, but luckily you know someone who can do a much better job at finding things than you can.
