...

Gaz's hands slide back down, and his palms are warm and rough over your belly and hips. It's all he can do not to crush you against his chest and take what he wants. He can't stand how helpless you look.

Soap's eyes are on your legs. His hands nearly engulf your calves. He hooks his fingers under your knees to open your legs further.

You watch them softly, offering yourself to them in your trance.

Gaz watches Soap dip his head and run his teeth over your calves. "Stay still," Gaz repeats. "It's easy to do what we ask. Isn't it?"

"Uhm..." You shift your hips at the ticklish feeling Soap's mouth is giving you.

Soap glances up from your legs to your face. Your eyelids droop, breath steady and body warm. He strokes your leg with his thumb and then slides his hand higher, making a low sound in his chest. "You don't need to answer yet."

"Okay."

Gaz's hands shift lower. His claw-tips brush the waistline of your shorts. "I’m curious. You said before--humans mate for fun just like mer do." Gaz's voice is still low and sweet, and his hands slide up and down your lower stomach. He pushes your shirt up an inch. "How long had it been since you've mated with another human?"

"I dunno." A lazy, obvious lie.

"Yeah?" Gaz's fingers move ever so slowly up to your chest. "Have you never been mated before? You want to know how it feels?"

You look away and watch Soap, who in turn watches Gaz lift your tattered shirt higher on your body.

"Or it's been a while," Gaz murmurs. "Long enough for you to be needy."

Soap, to his credit, keeps his nature in check. As much as he wants to seize what he wants with both hands, he's stock-still. His eyes are ravenous at the edges of your torn clothes.

Gaz strokes the hair back from your ear. You're dimly aware of the cold air and sea spray reaching your chest as he pulls your tattered shirt away. His hands feel so good. Soap leans forward, and his tongue, rough and warm, slides up the swell of your breast and scrapes against your nipple. You jolt. But Soap’s weight in front of you and Gaz at your back keep you where you are.

Gaz studies you as you surface briefly and squirm. He’s enthralled with you the way he is with everything else he can see from the water but never touch. Rare and prized. A human--something he's wanted in his grasp for so long, and now that has you in his greedy hands, he's determined to smudge his fingerprints across every shiny inch.

"Let him feel you," Gaz murmurs, a hand sliding up and under your neck, tilting your head up until his breath fans down your neck. "Let me see."

Soap's tongue drifts down your sternum and against your belly as he lowers his head. You shift. The urge to stir within this pleasant dream grows the more their hands and mouths run over you. It’s too good. Gaz's hypnotic suggestions can't quite quell your body's natural instincts to buck and move with idle pleasure under their touches. Your eyelids flutter. Your limbs are full of mercury, heavy and liquid. Gaz's voice floats over you, and his hands roam every inch that Soap hasn't already covered.

Gaz's hand slides from your neck into your hair and pulls your head back to kiss your open, panting mouth. The movement makes your back arch. Soap takes full advantage. He nips at your tits with shark teeth.

You gasp, hips jerking forward, and momentarily surface from the trance with Gaz's tongue in your mouth, Soap's teeth on your chest, his hands squeezing your tits, and two of Gaz's fingers pressing down on your core through your shorts. You're already pushing your hips up against his fingers, waking up in the middle of the act your body has already acquiesced to.

Your groan of confusion is swallowed by Gaz's mouth on yours. He keeps your mouth open and your chin tilted up as his fingers work you over your shorts. You can’t hide how you respond--your hips move to press more sensitive nerve endings against his claws.

Soap feels your chest push out as you swallow your complaints. "She supposed to be waking up?" Soap mutters drunkenly with his mouth full of tits.

But Gaz isn't shocked. "She likes this," he replies. "Feel."

Soap's hand joins Gaz's, and you feel his thick, rough fingers push against your core alongside Gaz's. You're already wet and responsive. He groans a curse against your skin.

As Gaz pulls away, your hips keep circling and your eyes begin to close again. Your wet folds stick to the fabric of your panties, slick and cold. "Nn, what's happening?"

Gaz looks down at your half-lidded expression. "I'm afraid we're taking our time with you."

"Hard to keep your eyes closed when you enjoy it so much," Soap says. His hands slide up your thighs and back down again like he’s deciding what part of you to touch next.

Gaz's thumb slips down against your core again and presses down harder. You pant and let your head fall back against his chest. You try to remember why you shouldn't be doing this, but it just seems so much easier to let it happen. To let it feel good. They're just curious about you. About your human body. Right?

You feel Gaz's hand slide around your torso again, pulling you closer. He guides your legs open and you feel Soap slot his body between them. His body is so warm and heavy. Gaz rubs you from behind you as Soap's mouth works your chest again, all slick tongue and mouth.

Gaz’s clawed fingertips hook the tattered fabric of your shorts and pull gently. The fabric begins coming off in downy strips. Soap's mouth is on your core before it's all stripped away, tongue lapping at you between strings of saltwater-soaked polyester.

Gaz’s chest vibrates behind you again, and his hands slide over your legs and hips. Soap's mouth works between your legs, and Gaz slides his fingers through your hair and over your shoulder. "How does she feel?"

"S'all soft," Soap mumbles. He slides his hands under your thighs to keep you open.

You wriggle against the odd sensation of Soap lapping circles around your hole and finally sliding in. His tongue is so big and wet. It goes so deep. You feel dizzy.

Gaz watches--feels--your hips moving against Soap's mouth with half-open eyes and parted lips. You grab Gaz's arm with one hand, digging your nails into his forearm in your haze. Your other hand goes to Soap's hair, grasping the wet strands roughly. Soap groans against you. His fingers dig into your thighs and he pushes your hips back to him. He wants more. He wants to pull you against his mouth and work you harder, but it’s difficult with you in Gaz’s lap. He hands slide up to grip your hips.

"Ah..." You feel Gaz's cock emerge from its sheath underneath you and squirm, dizzy. You should pull away, but then you feel yourself tightening up around Soap's tongue. "W-Wait, I can't--"

The plea turns into a cry as an unexpected climax seizes you. You clamp down hard on Soap's tongue, your legs trying to squeeze together despite his hands holding them apart. He doesn't stop. Not until Gaz pulls you away from him to lay you on the gravel on your side, your back still pressed to his chest.

You remember again you should protest. But at what? In his hands or Soap's--it should make no difference. Your pussy felt so good with Soap’s tongue inside it. His saliva is all over your slit, mixed with your fluids, coating your thighs.

Gaz’s lust makes him restless. He wants to leave his mark on you. He nips the shell of your ear, his hand sliding to your hair again. You bump back against his cock, standing ready so close to your pussy. Your hips shy away, but he doesn't let you go far.

He bites and grinds against you. The friction isn’t enough. His hand slides down to your hip, his nails sliding along your lower belly.

He wants you but he doesn't want to break you. He has to compromise. With his hands on your hips, he slides his length through your slippery thighs.

You gasp at the feeling against your oversensitive outer core. You stare down to see him poking out from between your thighs, glimmering with your slick and Soap's spit. He's big. So big. Maybe too much to handle. But you can't hide your real thoughts as he slides his hand lower to rub your poor swollen clit and feel how wet you still are.

You squeak and gasp. Every roll of his hips is going to skewer you, you just know it.

"Gods, human," he growls. It has nothing to do with the shark-like parts of his brain. His chest rumbles against your back, and his breathing is heavy in your ear. You have him so riled up that it's all he can do not to bite you hard enough to draw blood now. "I'd hurt you if we did this," Gaz whispers, his breath hot against your neck. He groans softly as he slides through your slickness. "We'd hurt you, wouldn't we?"

You're sensitive and wet and close, and you don't want his perfect hands and perfect voice and perfect length to go away. "No, ah--! Put it in!"

He grips your waist and pulls you harder against him. "You don't know what you're asking for."

"Put it in, please.” You try to angle your hips back toward him even while he stops you.

He makes a sound of heated irritation. The vibrations resonate through your body and make your thighs clench harder.

"You might regret this," Gaz says. The more you beg and plead the more his mind is clouded by the need he feels.

But the look Soap is giving you. Like he wants you just as badly as Gaz does but in a dozen worse ways. And you know he knows what you're asking for, too.

Gaz must see you looking at Soap, because he snarls and thrusts between your thighs, jerking you back roughly in time with his movements. You cry out in surprise and delight. The gravel bites into your arm and hip, but you're too dazed and ecstatic to care.

"Use me," you pant.

Soap looms closer. His hands slide over your body and he licks a hot path up your neck to your jaw. He mouths your earlobe and his shark teeth graze your neck. "You wanna get hurt, hen?"

"Mm!"

Soap pulls your face up to meet his. It's a chaotic kiss--teeth, tongue, open-mouthed and messy the way he likes it. He can't get close enough.

All the while, Gaz's hands are on your hips, your waist, your thighs. He's biting at your neck and shoulders and growling into your ear. "We don't want to hurt her," he hisses. But his claws leave tiny pricks in the skin where his grips you.

You're lost between them. Soap bites your bottom lip and it stings with saltwater. Gaz angles his hips up to keep himself from sliding inside you, and you moan desperately for more stimulation.

You're so close to having him inside. You know how much he wants he wants to stretch his way inside. And Soap's teeth are on your neck again, his hands exploring, wanting to touch so much of you as your mouth is occupied with his. You're so small and soft, so warm and receptive. He wants to do whatever will make you feel good. He's dizzy with it all.

You squeeze your thighs together around Gaz's length. If he won't use you the way you want, you'll just make him feel good like this. You have to.

Gaz groan of pleasure blows through your hair. His hypnosis was too effective. Not only are you docile enough to let them play with you--you want this so bad it's driving him over the edge of his cratering willpower.

Soap's teeth are sharp and his tongue is warm, and for a moment you just lean back to let him take control of your open mouth. He's got your chin tilted up with the pressure of his lips alone, and his tongue slithers along yours to pull the taste of you from your mouth. One hand comes up to squeeze your jaw, keeping your head tilted forward, and your body is so small—so easy—that it's so natural for his other hand to wrap around your neck.

As soon as his hand tightens gingerly, you moan. Gaz tenses up behind you. Then he starts railing your thighs for all he's worth.

They both feel the moment change. It's like a switch is flipped.

Gaz feels how wet you get once Soap's hand tightens around your neck, and he leans down and kisses you. Gaz's lips graze your neck, too gentle at first, and then the kiss turns into a bite. His teeth sink in, breaking the skin and making you cry out. He empties himself between your thighs, thrusting furiously.

You squeal with pain until his movements grow languid. The sharp pain clears the fog in your mind somewhat as his mouth unlatches from your shoulder. Your neck is stinging, your skin and muscles protesting. Gaz kisses the mark he left. Your hips are going to be sore and covered in bruises come tomorrow. You push on Soap's chest, trying to get your bearings.

He hardly notices your comparatively small human hands pressing against him and doesn't budge. He laps at Gaz's bite mark on your shoulder. He needs more. He pulls you forward into him to press his length against your core.

"Help me help you," he says, voice low and rough.

"Wait, it's--” Your voice wavers. Too big. You think it's too big--he wonders if you really mean it, or if you're just afraid. It's big, and big is dangerous. But you're not supposed to say no. You're supposed to agree. You're supposed to let it happen.

Soap glances up at Gaz with an expectant look.

Gaz looks down on you, laid out under Soap, with dark eyes. "Don't fuss," he murmurs. "You remember why?"

You gasp as Soap ruts against you. Your mind is tattered, buzzing with the desire to lay down and be easy--but just as much with the need to orient yourself, Gaz's hypnotic voice be damned.

"Just lie back and let Soap feel how good you are," he says. His voice feels distant now. Your thoughts are scrambled, and it's still too hard to listen to your instincts.

You arch as Soap ruts again, your struggling turning into pleased overstimulation.

He feels the fight going out of you. It's about time. You need relief, he’s certain. You need someone to make the right choice for you. Soap flips you onto your stomach. His hands are all over you, dragging down your sides, shifting your hips, spreading your thighs. "Such a convenient place for a hole," Soap says, smirking. He circles your entrance with a big fingertip.

Before you can decide whether to protest or not, he sinks his finger into your tight heat. You gasp, pitching forward with your forearms onto the rough gravel.

Soap slides his finger back and forth curiously. He plunges another inch every thrust. You're so wet he doubts you can feel anything but the size of him. You certainly don't seem to mind how big his fingers are. Or his claws gliding past your walls. In fact, the deeper he goes, the more you press your hips back into his hand. His smirk turns into a crooked grin. "Think she likes this, aye?"

"No argument there," Gaz says. He coils in front of you on the gravel and pulls your chin up to look at him. With your head angled up, he sees the flush on your face and the dazed look in your eyes. He tucks some hair behind your ear. Your neck is marked where he bit you. It's not even bleeding, but it's bruised and shiny. His eyes darken.

His teeth marks span most of your shoulder. His hands, too, are bigger than yours. He could wrap the entire lower half of your face in his fingers to keep you in place. To guide your mouth where he wants. The idea is more than a little attractive. "She's so small we can touch everything at once," he muses.

"Think she’d like that?”

Gaz looks at him and smirks. "She doesn't seem to be doing a lot of thinking right now."

You gaze up at him as best you can. Your eyes are half-lidded. You grasp his hand with one of yours, your tongue slipping out of your mouth to run up his fingers.

"So, so small," he says. His thumb and index finger pinch your jaw. "Careful," he murmurs, voice low. "Watch those teeth."

His thumb goes to your plush bottom lip, slips into your mouth, and rests gently over your tongue. You hollow your cheeks. The suction is too gentle to stimulate him the way he'd need, really. He shifts to lay out in front of you and presses down on your tongue to keep your mouth open. "You've got no room for me in that pretty mouth of yours, do you?"

"Ahn?" you reply dimly.

Your pink tongue and tiny human teeth fascinate him. He can't believe something so small and harmless is dangerous enough to have earned you a place at the top of the food chain on land. He's even more fascinated by the way you're sucking on his thumb and rubbing it against your tongue’s rough, warm surface. He chuckles and shifts his hand under your chin again to hold you in place. "No, a little human thing like you hasn't got room for one of us," he says. "All I'd have to do is push a little, and you'd be full up."

Soap groans. "Fuck, yes." He worms a second finger into you and you squeal.

He's careful--he really is. Soap might be a bit rough sometimes, but this is nothing compared to his usual way of doing things. Gaz's eyes follow the line of your throat you arch back.

He looks up at Soap and his smirk turns vicious. "You getting something out of this?"

Soap's gaze flicks up. He adds another finger and you whine. "What, it's a competition?"

"When is it not?"

While they bicker, you bend yourself into position after position to better take Soap's fingers. You finally manage to ease all three in and grind your hips back against him with a heavy breath. You're dripping--not just with Gaz's spend, but with your own slick.

Just then, right as you’re starting to rapturously enjoy all three fingers, he's pulling them out of you and positioning himself between your legs.

Soap puts his hands on your hips and looks up to see the stare Gaz is giving him. "I was playing fair," Soap argues, dropping back into the mer-tongue. "You weren't."

"Watch your size," Gaz warns. "Don't play too much and hurt her. She's small."

"Why? You want another turn after I'm done?" Soap says.

It’s not that. That's what Gaz's eyes say. In fact, he doesn’t much care for Soap having a turn at all. Gaz wants to fill you full by himself and keep you that way.

But his lips stay clamped shut. Soap gives him a knowing, sly smile.

"Don't get greedy," Gaz says. There's bite in his tone. "She’s my catch."

Soap lets it go for now. His attention drifts back to you and all the things he could do.

You rut backward impatiently. "What are you talking about?" you ask.

"Don't mind us," Soap says, grinning. "We're just figuring out how we're going to play with you."

He pushes himself against you and the size difference is enough to make him pause. He could just press you into the gravel without any effort. He would love to use you in so many ways, but he's holding back. He doesn't want to break Gaz's apparent hypnotic hold on you.

You sigh and push back against him. You manage to catch his tip in your folds, but you can't quite make it go in. Soap hisses softly at the feeling. It's all he can do to keep from pushing all the way in to your wet warmth. Instead, he leans forward and plants his hands on the hard ground, surrounding your body with his arms and waiting for you to move.

You try bouncing backward, riding his tip, determined to take him in. You don't fully understand how much trouble that will be until you ease yourself back enough to stretch your pussy as far as three of his fingers had. You glance back to see you haven't taken him all in yet--not even close. Then you feel a strange bump up against your clit and look down to see him sporting not one cock, but two.

"Oh," you say in a distant voice.

"Not too observant for a human," Gaz says. But then, it's partly his fault you're too focused on trying to bury some cock in you to notice they both have two.

Your gasp turns into a long, breathy moan as Soap pushes into you a few more inches. You're slick and ready inside, but you slide your legs apart further, needing to take more but unsure how you'll make it fit.

"Easy on her," Gaz says again. "She can't take all of you."

Soap looks back at Gaz, his eyes dark. "You seem awfully concerned about her all of a sudden."

Gaz scoffs. "I just know you. I know how impatient you are."

You ease back and circle your hips until you've seated him as deep as you can. Then an inch deeper. Soon enough you're rocking back and forth, fucking yourself of on him and making terse, dreamy sounds of need. Soap lets out a ragged breath. It's a squeeze, but worth it. So worth it. How'd Gaz find one that feels so good?

You spread your legs as far as you can to accommodate his girth. You feel air-tight, like it should hurt, but every tiny movement you make sets your nerve endings alight. There's pain in your palms against the sharp gravel, dull scraping against your kneecaps, and an impossible heat burning in your lower stomach. Pleasure-pain glazes your already-distant eyes.

Soap begins fucking you slowly. Not that he holds much concern for your strange human senses and boundaries--it's more that he wants you nice and tame. Gaz notices that hesitation despite being distracted with your moaning and begging and wiggling as Soap spears into you steadily over and over.

"Thought you wanted to break her," Gaz says. He speaks your language to taunt both you and Soap.

Soap grins. "You went to all this trouble to hypnotize her. Wouldn't want to jostle her too hard, aye?"

Gaz smirks. "Don't worry about that, mate. You know there's no way to hypnotize someone who's unwilling."

Your breath hitches. "What?"

You hear Soap smirking as he says, "You aren't going anywhere, are you now?"

He presses into you with a long, deep stroke that turns your protest into a shuddering moan.

"Told you she wouldn't run," Soap says.

After that, you can't manage much coherent thought at all.
