Rapier and Gladys, despite only being uplifted for a few days, were actually becoming quite comfortable with it. The remedial lessons helped a lot with learning things that would be necessary for dealing with future tourists. During the investigation of the Freaky Tiki Encounter, they managed to find wetsuits and rebreathers designed to resemble Polynesian sea demons, which seemingly fit with the other clues everyone else found.
All through everything, Rapier and Gladys felt a growing attraction toward each other. This built to a point when they felt what could be called the 'bondmate bond' growing between them. When they asked for some time alone, the others were more understanding, even if they pointed them toward the central lagoon.

"Are you feeling the same urges I am?" Asked Rapier, as they entered the cordoned off area that was for underwater mating.
"I sure am," answered Gladys, reaching for his shorts, "and I want it to be with you."
"I wouldn't want it to be with anyone else." Said Rapier, reaching for Gladys' bikini top. After he pulled it off, he fondled Gladys' new breasts, causing spikes of pleasure to fill her.
"At first I wondered why I had these," said Gladys, in between moans and gasps of pleasure, "Now I wonder what I would have done without them." When Rapier stopped groping them and reached for her bikini bottom, Gladys took the hint and reached for his shorts. As their bottoms slid down, a massive, 16-inch malehood slowly stretched out of a slit in his crotch.
"Ooh! That's... big!" Said Gladys, not knowing what else to say.
"And it's all yours." Said Rapier, discovering a vulnerable spot between her legs. At what he was implying, Gladys lay down on her back and spread her legs. Rapier needed no more urging.
"If, *unf*, this is how humans, *oof*, mate," said Gladys between Rapier's thrusts' "I hope we don't, *mph* die afterwards."
"If Rita, *huff*, and Ralph can survive," said Rapier between thrusts, "we cer-, *puff*, -tainly can!"
Shortly after, both Rapier and Gladys noticed that they were both getting bigger. Rapier remembered that the term was 'double dosed' to describe those who were exposed to the virus twice. They decided to hit release as soon as possible, and started to go faster. All too soon, their climaxes hit and they screamed out as they both released and slowly fell unconscious.

When they came to, it was dark and the stars were out. They dressed themselves as best they could, considering what they wore before was a few sizes smaller. When they came to the luau, everyone was surprised to see two great fishy titans walk into the firelight.
During the "remeasurements" it was discovered that Ran and Rapier were exactly the same in height, weight, and build, while Gaz and Gladys were also the same in height, weight, build, and 'female development'. The two couples decided to have a kind of friendly rivalry toward each other while helping both get stronger for the upcoming IAC.
Joe and Jane knew they would never get to the sizes of Ran and Gaz or Rapier and Gladys. But they also could feel the 'bondmate heat' building between them.
