Haruka had just arrived at the fancy swim center, for a one-on-one race against Rin, who was already waiting there in his swim suit; he shoots him a smirk when the other steps closer. "You showed up. You'll wish you hadn't once I've won."

Haruka takes several long strides forward, removing the no longer necessary layers of clothing, stopping but a few feet away from Rin. "You knew I wouldn't run away from a chance to swim." Rin stood up and put his cap on, walking just inches from the other boy.

"Good. All the better when I crush you. He purposely bumps into Haru's shoulder as he walks to the starting block, pulling his goggles on, stretching his legs. Haruka walks up to the starting block and pulls on his own goggles.

"Sometimes I wonder if you even enjoy swimming at all and if it's just all about winning for you Rin. Do you ever take the time to feel the water's caress?" Rin rolls his eyes under the goggles and stretches his arms.

"The water's caress... heh, sometimes Haru-san, I wonder whether you're still that silly little kid." He retorts and leans down, getting into the starting position.

"You still think it's childish to enjoy the world around you or to enjoy a pleasant sensation? I wonder if you learned anything at all in Australia. Did no one ever touch you, hold your hand? Water surrounds you and holds you like no person can or will and yet you let it go unnoticed. Hrph." Haruka stretches and muscles shift under smooth skin as he looks down at Rin in his starting position looking for any kind of response.

"You only speak of distractions. But no matter, you will never beat me again, Haru." His fingers curl around the edge of block and his strong arm muscles tense. "3...2...1.." They dive into the pool and Rin immediately shows off his training in well-executed long strokes. Haruka's powerful legs lift up and down just under the surface of the water propelling him forward. He soon hits the end of the pool and his body twists and changes directions headed back to the starting block. But Rin's strength and endurance from all his training in Australia, especially with the drought of practice counting against Haru, he's several strokes ahead by the time the dolphin completes the turn. It's clear that no matter what he does, in this race, the red shark is going to dominate. When he reaches the end of the pool, he turns to Haru's lane.

Haruka reaches the end of the pool and his body twists as he meets the wall, hand holding onto the edge. It's clear to see he's restraining himself from turning around and continuing. Every fiber of his being is telling him to swim. His eyes slide over to glance at Rin's expression and Rin is anything but conciliatory, smirking even as he's breathing heavily. He swims under the lane divider and suddenly pulls Haru by his goggles, flush against him. "Tell me how it feels to lose, Haru. Tell me how it feels to know you've lost it."

"I feel good. I got to swim, to enjoy myself, to see you really smile for the first time in years. I don't have your competitive streak, Rin. Yes, I wish I could have won, if only to have the chance to watch you realize there's more to both of us then a simple competition." His hand rises up out of the water, dripping wet, and caresses Rin's cheek gently before tangling in his hair. He leans into Rin, their lips almost touching. "Don't you feel it? It's like an ocean current. Please tell me you feel it too?"

Rin's smirk doesn't fade as Haru plays with his hair, his eyes only close slighlty. "The current... perhaps... but if this is the ocean, Haru-san... then you'll always be in danger of being devoured by the shark.." He says heavily. He leans slightly to the left, finding a spot on Haru's neck and begins sucking roughly. "You have no use but to give in to power.. my power."

"I wouldn't really call it danger, after all if this is the ocean I have an overprotective shark all my own who keeps an eye on me. He nibbles a little but it's nothing I don't enjoy." Haruka's pointed look makes it obvious that he's referring to Rin, and not without a gentle tone of amusement in his voice. His hand wraps under Rin's chin and pulls the swimmer up for a light kiss. Lips graze each other before his tongue slides over Rin's bottom lip. Haruka makes a near inaudible whimpering noise, asking for permission to kiss his shark. Rin closes the gap, granting his request, as he presses his lips against Haru's hard, already pushing against the other's tongue. At the same time, he's pulling on his dolphin's hair, just a reminder who's in charge.

Haruka feels the cool press of the pool wall against his back and wraps an arm around Rin's waist and lets the other rest on his shoulder, trusting the other to keep him pinned and afloat. He lets his tongue slide along Rin's, gently pushing back against the other's forcefulness. As the hand threads into his hair and he feels the sting on his scalp a moan escapes his throat into the kiss. Fingers twitch against Rin's skin as Haruka's nerves sing with pleasure.

"Such a good dolphin... smart as well... the power of the shark, yes, even with those he protects, is not to be underestimated..." Rin, aroused at the submissive sounds from Haru's throat, pulls again on Haruka's hair with his left hand, while his right hand keeps the other afloat, even as it rubs along all the curves and bumps of Haru's ripped stomach. He pushes forcefully back against Haru's tongue, before leaning back from the kiss and biting hard, maybe too hard, on his bottom lip. "Be careful, for the shark has few limits."

A shiver runs through Haruka's form at Rin's words. He's sure Rin can feel the quivering in the hand grazing his abdomen. Haru moans lowly with the continued sting of his hair being pulled. A loud whimper echoes through the room when Rin bites his lower lip. "Y-yes, I can be quite, ah, clever at times. I'm certainly clever enough to know I like a little danger and that I enjoy the pain as a counterpoint to pleasure."

Rin smirks again at the whimper and moves his hands up to Haru's shoulders* "My, I didn't know my little dolphin was so needy. But of course, your protector is oh so willing to assist. As I please anyway." Rin tiptoes his fingers down Haruka's stomach again, before he reaches the top of Haru's swimsuit. He slowly pulls the dolphin's swimsuit down, before it's caught around the boy's ankles, keeping his legs from moving too much. He does the same with his own, however, takes them off completely. "My little dolphin. Let's hear some more."

Rin reaches down and slowly rubs the underside of the other's cock, as he leans down on Haru's collarbone and gives it a hard bite. Haruka gasps and responds breathily, "O-only for you. I've always wanted to be with you, like this. Even if I hadn't, ahhh, realized it before. Fuck, R-rin. Please!" His hips rotate and thrust against the other's hands. The hand that rested on the shark's shoulder slides down to pinch a nipple before continuing on it's way over defined muscle and around Rin's cock. The hand slides up and down the other's length hoping to return the pleasure he is receiving.

Rin makes a soft moan from the rubbing as he wraps his hand around Haru's cock, pumping him slowly, but with a firm grip, his own free hand resting on Haru's shoulders. "I-f-felt the s-same- n-now. Hgnn! M-make noise for me dolphin. M-moan for me."

"What, I haven't been making enough noise for you a-already? mmhph! Or are you looking to get caught by your coach? Ooohhh fuck." Haruka's hand keeps the steady pressure and pace, but he makes sure to press his thumb against the head of the other's cock, fully intent on making his shark moan too. Rin cries out then moans out at Haru's actions, rather embarrassingly from his earlier tone; he's at risk of falling onto Haru, something he will not have happen. He stops pumping Haru and forcibly turns him around, pressing his chest into the cold wall. Haruka lets out a squeak at the sudden change in position. He grabs the wall with both hands to steady himself before grinding his back up against Rin. Rin brings his hands down to wrap around Haruka's hips and breathes hot air into the dolphin's ear. "Mmm- l-let's get back to what m-matters, m-my power. T-time for the shark's real bite."

"G-give me a real sharks bite, Rin. Show me how deep it goes. I need, mmmhph, you." Rin manages to let out a chuckle as he leans flush against Haru, his erect cock resting against the other's rear. He slides a finger into Haru's opening and wiggles it around before adding a second, perhaps a bit too soon after scissoring with the two fingers he adds a third.

"And I need you my dolphin." He pushes himself in slowly while at the same time, biting softly on the nape of Haru's neck. Haruka is quite glad he masturbates as much as he does, this would've been more than just uncomfortable if he wasn't already used to having objects enter him. This was nothing like that. It was better. Warm and softly pulsing with Rin's pulse. A choked sob of pleasure escapes his mouth before he can manage to bite his lower lip to stifle the noise. He leans his head back against Rin's shoulder and breathes deeply. "R-rin, oh, gods. M-move, please!"

Rin is kind enough to comply, gripping his shoulders, he begins a slow thrusting action which gets faster and faster. Eventually, Rin can't even bite or play with Haru's neck, only lay on his dolphin's shoulders, breathing warm air as he moans into his skin. "Ahhnnn-H-Haru-f-fu-fuck-"

Haruka snaps his hips back meeting each of Rin's thrusts. Haruka can feel the pleasure coiling tighter and tighter, soon to snap. He can almost feel his ass starting to clench around Rin's cock. "Is my s-shark gonna cum inside me? Please, Rin. Fuck."

"F-fuck y-yes H-haru-g-get-r-read-ahh-!" His neck tilts back as he breathes out his answers. He sinks his nails into his shoulders as he releases, moaning into Haruka's back, muffling his scream of pleasure; he tries to put his hand up to Haru's mouth, knowing being too loud wouldn't be safe, but at the same time, in absolutely ecstasy. Right as Rin warns Haruka of his impending orgasm, Haruka's begins and takes hold of his body. His inner muscles clench around Rin's cock, milking him for all he has. A moment later when the blinding white pleasure clears from his vision he sees Rin's hand. He releases his lower lip from the bruising bite he had it in and nips, licks and kisses the fingers before him. "Rin..."

Rin, still breathing heavily from the intense orgasm, lays his head down on Haruka's shoulders, humming against his skin. He slowly pulls out, but stays behind Haru. "Mhmm?..."

"Mmmm, good?" Haruka too breathes heavily in the wake of his orgasm. He turns his head to nuzzle against Rin's and basks in the afterglow right alongside him. He's sure he has a few bruises and scrapes from having sex against the side of the pool. Rin's bite marks will probably last longer than any of them though and that thought brings a smile to his face. Rin smiles, actually smiles, in this special and rare moment after all the intensity, before he gently kissed the back of his neck gently, still humming somewhat at the nuzzling.

"Good? ... Perfect, dolphin... Haru-san... absolutely perfect." He starts lazily rubbing circles in the sides of his arms, leaning against the other boy.

"Hmmmm, I'm glad you think so too. I can count on that happening again soon I hope?" Haruka replies and gently moves Rin off of him just enough to turn around and face him. He holds the shark tenderly and places kisses starting at Rin's ear and down his jawline before placing one on his lips. "We should get dressed when you're ready. Your swim trunks are at the other end of the pool by the way."

Rin smiles, rubbing Haru's cheek after he's done kissing. "More times in the future... you think I'd let you get away so easily?"

The boy's smile at eachother before Rin swims over to the other side of the pool to grab his swim trunks. Haruka lifts himself out of the pool and sit's on the edge with a slight wince at his own soreness letting his feet dangle in the water. "You'd hardly let this go, but I wanted to make sure and let you know I have no intentions on letting you run from this."
