Part 2 of 2.
 
The mares both took deep breaths as the shark dove under the waves, taking both Fluttershy and Rarity under with them. As the bubbles from the surface cleared, they took a look as they dove down at an angle, Tide picking up speed as Rarity felt herself push back against his dorsal fin as Fluttershy grabbed a fin. Soon, the shark slowed and corrected his body as he swam as a lesser speed. Rarity flashed a spell to help her see underwater, turning to Fluttershy to give her a dose but she refused it.
 
The unicorn looked around her at the underwater world she was in, staring at the schools of fish and tall seaweed towering over them as the shark weaved its way around the ocean, feeling the current wash over her naked breasts and exposed vagina.
 
She looked at the large, aquatic creature and felt a sense of excitement and wonder as imagined herself a mermaid gliding along the sea or a tribespony taking a ride upon her aquatic steed to hunt for food. As she slowly exhaled a cloud of air to relieve the pressure building in her lungs, watching it zip away to the surface, ideas of new designs for dresses began flooding her mind.
 
“Yes, all this sealife is giving me just what I need to get the creative juices flowing!” The unicorn thought to herself.
 
Rarity felt her lungs began to twinge as her cheeks puffed, she looked at the pegasus beside her who looked like she was taking her air situation much better than herself. The unicorn focused on enjoying herself rather than needing air, feeling the fin rub against her nether regions as she let out a stealthy bubble of lost air, “Gblbl!”
 
“Goodness, that was unexpected!” She found herself pinching one of her nipples, and quickly hid her hand away from her friend who looked on curiously. She shook her head as she continued to look around the underwater realm, still holding onto her gulp of air as they dove down again, Fluttershy still keeping a hold of the shark as he submerged down and down, Rarity looking up at the glistening surface, “I do hope she knows how to get Tide to surface, or else I may be in trouble.”
 
Rarity no longer felt afraid of the shark itself but of her current depth, worried that she may not get up in time. She saw Fluttershy confidently swim beisde the shark and realized she was in safe hands. The continued to swim around the tall seaweed stalks and swam around some fish schools and reefs as Rarity felt ideas coming in one after another, even reaching out to a few fish to get a closer look, but soon enough, her need for air became too much to bear as her lungs pranged inside her, “Hnngbl! Mmglp…”
 
Fluttershy noticed her friend’s struggles and pulled at her leg to get her attention, the unicorn puffing her cheeks and looking down at the pegasus as she pointed a finger at the surface as if to say, “Up?”
 
The unicorn nodded, bubbling again as she covered her mouth, “Nngblaagbl!!”
 
With a tug, the pegasus guided the shark back up to the surface as Tide began to ascend at a quick, but steady rate as the unicorn watched the surface come closer to meet her. Soon, she would get her breath of fresh air and tell her friend about the wonderful time she had and thank her for all the inspiration she was given on the dive. As the surface neared, the unicorn thought to herself,
 
“I wonder if Fluttershy does know where the dolphins are…”
 

 
I do want to use this shark model again as I want to put a pony in a ‘Shark Tank’ situation where a pony is in a submerged tank with a ravenous shark trying to get in. Not sure who I want to use for that one, but it’ll be soon.
