The dolphin girl realized you are a shark, and so, her natural instincts took over, she mean glared you, as if all the kindness and cheerfulness she presented when entering the beach had vanished, you both were natural rivals.
You crossed your arms, slightly squeezing your boobs and maintaining a calmed, but noticeably annoyed expression on your face as she started walking through the shore like a diva, swaying her hips from side to side, making her bubble butt bounce. You sighed as you felt that she was being too bubbly.
She approached you and you kind of looked at the opposite direction, ignoring her.
"Hey sista" she said in a squeaky voice, with a mean feeling to it.
"Enjoying MY beach...?"
You just sighed and ignored her for a while, but she kept speaking in her bubbly, squeaky voice while pressing her huge breasts against your arm.
"Too shy to speak, sis? I'm just trying to be nice, but I guess I'm a cup or two above your league...!"
You simply growled a bit, your heart pounding with strength and fury.
The dolphin girl then pushes you with her hips. "SuSu is too much for you darling? Not even a peep?".
You turn to her and lower a bit to talk to the slightly shorter girl.
-"For a girl with a breathing asshole stuck in the head, your brain doesn't get enough oxygen".
You grinned with your sharp teeth and flicked your opaque, short dark hair, your costume was altering your mind a bit now too.
She stared with an exaggerated astounded expression, and looked everywhere, thinking of a comeback.
"Well..." She wondered. "Says the girl that looks almost dead! Do you even have blood, darling? You look all pale, with an ugly, sharp face, tired dark eyes and just... Really... Really ugly hair!"
You turned to her once more.
"Shut up already, plastic princess, you came to MY beach, started acting like a fucking bitch and we didn't even talk for 2 minutes! Get your shit together and leave me alone for once!"
You shouted with incredible force, your powerful body had a strong voice.
SuSu's face became red, and she pushed you once again with her hips. "You heard me, hoe, name's SuSu, and the second my feet touched the sand, I freaking like, raised the bar! Booboo queen, you are bested..."
You growl and push her back
"Like I care bitch!"
She pushed you back and shouted again
"You seem to do, asshole!"
You kept pushed each other and abusing profanities for what feels like eternities, every animal in the beach staring at you two.
SuSu then backs up.
"You know, bitch, there's one thing that nobody has ever beaten me."
You laugh and tower her.
-"Being a pain in the ass"
She laughed sarcastically and turned serious.
"Swimming, babe." She said as she made one of the strings in her bikini smack her ass and make a loud whip sound.
You laugh once again and stretched, towering her even more while displaying your huge, feminine muscles to everyone in the beach.
"Yeah, sure"
You felt confident and strong, you could beat this dolphin girl any day.
She giggled as she stretched as well, revealing her soft, but abundant musculature.
"Try me".
You smiled and walked to an empty olympic pool in a sports complex next to the beach.
"I'm always in to presence an embarrassment..." you respond.
You both then walked and prepared in the total opposite lanes. You took the 1, while she took the 8. A large crowd of animals rushed to the pool and filled the seats to continue watching the drama.
You stretched and excercised your muscles, warming up for the race.
The lifeguard, a teenager in a cardinal suit called Agustin walked over, and noticed the girls on the lanes starting points, he rushed to the scene.
"What's going on?" He asked you.
"I'm about to wreck this bitch's ass in this swimming competition" you answered.
"Woah heck" he said "I may as well help here." He turned to the animals attending the sudden show and walked around the various rounds of seat. "Ladies and gentlemen! Or whatever you are now... I will be your referee for this sudden sports competition rivalry thing of nowadays! It will be... Um..." He rushed to SuSu.
"What's your name, gal?"
"SuSu..." She said kind of annoyed.
"SOOSU!!! against..."
You thought of a name quick... You just take the name on a list nearby of one of the girls attending swimming classes in the pool. "Tabitha!" you shout.
"Soosu against Tabitha!" He proclaimed before running and climbing the lifeguard turret. "I'm so fired... But anyways... Get ready girls... 3...!" You shook and entered in position. "...2!" You breath slowly... Your gills taking lots of air. "...1!" You feel every muscle tense, it was time. "...GO!".
It was it. You were queen of the animal beach and you were decided to protect your status, you hop into the water and quickly swim, every muscle working it's way through the water. Your gills finally were in their ambient, your body warmed with the rich oxygen the water gave you, swimming fast and fast, you concentrated as much as you could, but you couldn't resist watching were SuSu was. To your surprise, you were even, even if you swimmed at what you felt like 45km/h. Your strong shark heart pours adrenaline to every fiber of your body, you rush and rush, piercing through the water with a way above human speed. Everything was filling with bubbles... The race has just begun, and suddenly.
