The pair made their way out into the water, not too far from shore. In fact they made for a small rock outcropping in the waves that helped form a secluded cove away from sight. There placed down their tools and supplies and dove into the water. Not only to check on some of the local flora and fauna they had tagged when they were previously more..., professional, but also to enjoy each other's touch.
Losing their swimsuit, the pair dove into the water. Thoughts of studies and research gone for now; the pair only wished to spend time with each other. Katie leaned back into her wife's arms who wrapped tightly around her large breasts. A hand went below the water and felt their lover's pussy. Lips were captured, and skin pressed against skin as both of their breaths came out in hurried gasps and moans. No one would come all the way out here. Not until it was time for the beach to close; which gave them plenty of time.
Just them, the sky above and the water below. And all the love they were going to show their partner.
Well that's what they thought.
Even if it was a curated public beach; that didn't mean nature was completely gone. As the pair added their own juices to the water, something came along as it sensed the motion in the water. Was a creature thrashing? Was it wounded? And what was this strange... feeling it was having. And why did it seem to desire... more? That... thing or things in the water... it was coming from them..., it needed more.
The pair broke away from each other to catch their breath and to bask in the after glow of their session. That was enough fun for now right? Get some samples first, then another round. After all they did have a bit of work. And if they were fast, Katie would be in the lead this time. They traded who would top based on who finished their work first. Katie moved to go get some equipment left on the rocks when something touched her leg....
And dragged her under.
Robbie fought to not scream, a part of her mind still remembered that motion in the water would only attract attention. She had to go get help but before she could figure out just what to do she too felt something grab her leg and with a cut off shriek was pulled under.
The bubbles of the pair soon faded. The little cove was quiet once more with no signs of their passing save for a small camp that still held all their gear and discarded bikinis. But this peace was soon disrupted once more as a froth of bubbles started to erupt from under the water, billowing out as something started to emerge from the sea. Just what sort of creature had grabbed them?
