After signing the contract, you immediately start feeling something rising within your stomach so you sat down to join Wendy in the sand.
As you joined your girlfriend, you felt a compulsion to bring your legs together. You tried resisting this at first but soon your legs were drifting closer together, and no matter how hard you tried you just couldn’t force them apart. Eventually, however, the magic began to grow stronger on your legs as they continued inching closer together, until at last they touched.
Immediately, the muscles began to spasm and your thighs pressed harder against one another, fusing seamlessly, with separation between your legs closing like a zipper. Your heels began to lock together as well. Before you knew it, you didn't have two legs anymore.
Wendy and Alora watched eagerly as you felt red scales grow on your disappearing ankles. Each scale felt like a small kiss to your legs, causing you to shiver a bit in pleasure as more scales began to sweep over your lower body.
As the scales continued to go up your fused "leg", your toes began to stretch and flatten out into fins. You wiggled your new fins and smiled.
The scales soon ripped apart your swim shorts, and continued their way up until they reached your torso and finally stopped. You were now a merman.
"Woah…" was all you could muster as the sheer awe of it all washed over you. Before you could say anything else, Wendy grabbed you into a tight hug and gave you a kiss.
"You look so handsome as a merman!" Wendy gushed.
You blushed but couldn’t help the smile appearing on your face. "Thanks, Wendy. You look amazing, too."
"Didn't hurt, huh?" Alora said a smirk.
"No… In fact, it actually felt quite good." You said as you looked down your tail. The red scales glittered in the sun like little rubies, like how the yellow scales of your girlfriend reflected the sun like gold. You couldn't help but grin at the sight.
Then, you felt some of Alora's tentacles sliding under your shirt.
"Woah. Hey, what are you doing?" You asked, squirming.
"Relax. Since you're going to be underwater, the shirt's only going to hinder your swimming." She said as she took off your shirt, revealing your naked upper body to the world.
Admittedly, you felt a bit embarrassed being in the nude in the open but your nerves soon calmed down as Wendy laid a gentle hand across your chest.
"You don't look half bad like this." Wendy said. "I can imagine your body's gonna look even better after some swimming. Right, Alora?"
Alora nodded. "Swimming for a long time tends to be a good workout for the body. I've had more than a few cases where a client goes from being chubby to buff the second time I meet them." The cecaelia said as she tossed the shirt near Wendy's towel.
You looked back at your girlfriend with a warm smile. It really hit you that you not only had a mermaid as a girlfriend but you were also a merman too. Two legendary creatures of the sea, together at the beach. It felt like a dream come true.
You saw Wendy smile back as well, no doubt she was thinking the same thing.
Soon, you and Wendy two of you shared a long kiss together as undersea lovers. Merman and mermaid.
