“Yes.” Janine said, and she began anxiously unbuttoning her blouse. “I must confess, if it were anyone else telling me this, I’d have said ‘no’.” She said as she slid off her skirt. “Somehow, with you, I feel safe.” Janine stopped. “Uh, that didn’t sound too weird, did it?” She asked, embarrassed.
“Not at all.” Cleo answered reassuringly. “If it were anyone but you, I’d have never even let on I knew how to make you a mermaid in the first place.”
Once Janine was fully disrobed; she carefully slipped into the pool and into the waiting arms of Cleo. “It’s not too late to back out.” Cleo said. “Once the transformation starts, there’s no going back.”
Janine wrapped her legs around Cleo’s tail and said, “I’ll take my chances,” before pressing her lips into Cleo’s.
As the two made out, Cleo’s vagina opened and her clitoris elongated, entering Janine’s vagina. Cleo broke the kiss to let out a short gasp.
“Don’t worry, it’s just how we make love. It’ll be even better once yours becomes like mine.” Cleo started to buck her hips and Janine responded with short moans. Janine soon found the strength in her legs waning; it felt as if they were thinning and shrinking. Not only that, but her tailbone started to move and even seemed to grow.
“This is it,” Janine said. “I’m becoming a mermaid!”
Cleo pulled Janine underwater as her assistant’s breathing quickened. Bubbles spilled from her mouth as water took its place. Janine’s submergence served to accelerate the transformation and in almost no time at all, Janine’s legs had shrunk away, her tail was fully formed and her clitoris had lengthened to coil around Cleo’s. The mermaids continued their ministrations for some time before they both finally climaxed. It was Janine’s first mermaid orgasm; and it was every bit as intense as Cleo’s, which outclassed even her first one.
