Yes she does!

The diver's rope was slung around the mermaid's torso locking her arms at her sides. She thrashed around like a fish, bubbles coming out from hard breathing and her shiny green latex sparkled in the water as the diver and pulled her down to the bottom of the tank.

At the bottom of the tank was shackles chained on the floor. The diver chained the mermaid's wrist upside down to letting her latex tail swish around floating to the top. Snaked at the bottom was a line and bubbled at the end was an oxygen line. The diver swiped the line and inserted it into the mermaid's mouth. The naked diver then kicked up to the flapping tail. The diver hugged the upside down mermaid as the smartex gave way for the diver's mouth which promptly fished around the mermaid's wet pussy.

The mermaid's face went wide with pleasure and moaned out bubbles. The diver pressed her breasts into the mermaid's lumbar and hooked her legs around her slim tan body. The diver pressed her heels around the mermaid's bouncing breasts as the mermaid squirmed in pleasure.

The diver's tongued inside the mermaid for a bit until the mermaid went stiff and tense. The mermaid screamed out and you could even hear it from outside the glass. The mermaid's juices flowed out into the water making the other mermaids who were swimming around the sides, tingly with pleasure.

With the diver satisfied she swam to the surface and stepped out of the tank with metal grates, leaving the mermaid dazed with pleasure until her friends swam to unchain her.
