When Diana Lyall reached the lake, she found her girlfriend Sylvie Forrest already waiting for her in the water. Sylvie, a beautiful tanned blonde with vivid green eyes, was still in her human form. She swam up to Diana, leaped up onto the shore, and seized Diana in a tight embrace.
"I've missed you, Di!" Sylvie smiled. "Hope you didn't have any encounters with Luna on the way here."
"Nah, just Mom and Dad," said Diana. "They didn't give me any trouble."
"Not even your mom?" Sylvie laughed.
"Not even Mom," Diana laughed back.
An odd look suddenly came over Sylvie's face. She sniffed Diana. "You smell like werehyenas, Di. Where the heck have you been finding werehyenas?"
Diana blushed. "Oh! Ahhh... that's, well... Can you keep a huge secret from the entire pack? Even my parents?"
Sylvie blanched slightly. "From the alpha and his mate? Uh, sure. For you, Di. Anything for you."
"Okay," Diana sighed. "You remember my twin sister Selena, right? The wolfborn? Stuck as a human?"
Sylvie nodded.
"Good," said Diana. "Well, she's not human anymore. She's visited a witch and gotten herself turned into a werehyena. Now she's starting her own werehyena pack."
"Wowww..." Sylvie drawled. "Your parents aren't gonna be too happy 'bout that. Especially not your mom. I mean, I saw what she did to the alpha of that pack of were cougars that tried to settle on the western fringes of our territory. I wonder how he's doing with only one arm."
"I know," Diana said. "I used to kid her a lot, but Selena's got some seriously big balls... literally." Diana chuckled to herself. "You know how werehyenas are built."
"Yeah, those herms are pretty hot," said Sylvie. She began curling Diana's red pubes around her fingers. "Not that I need a dick to turn me on, Di. Your pussy is all I need." She glanced at the lake. "Shall we?"
"You don't need to tell me twice, babe!" Diana grinned. She took hold of Sylvie's hand and they both charged into the cool water of the lake as the sun set.
Diana sighed contentedly as the water lapped at her freckled skin. She kissed Sylvie on the mouth as they willed their transformations to begin. Diana felt he and her girlfriend's muscles bulge and harden. She wrapped her muscular legs around Sylvie's hips as their already ample body hair thickened into pelts of fur. The feel of their fur floating in the ethereal embrace of the water was heavenly for the lycanthropic lovers.
Diana began to grind her pussy against Sylvie's. Sylvie responded by pulling Diana towards her and smashing their breasts together. As Sylvie rubbed their nipples together, she felt her feet become paws, her nails sharpen into claws, and (best of all) her tail bloom above her ass. One look at Diana revealed she was feeling her own tail's growth, and it was arousing her like hell.
As she rubbed nipples with Sylvie, Diana felt additional nipples flicking over Sylvie's as their additional breasts budded. Diana continued to drag her clit over Sylvie's enjoying the weightless sensation of making love in the water. As she heavily kissed Sylvie, Diana noticed their tongues growing longer, flatter, and more dexterous. As their French kissing grew more acrobatic, the werewolves' faces pushed out into lupine muzzles and their ears migrated to the tops of their head and grew pointed.
As the transformation drew to a close, Diana felt her clit and nipples heating up. Soon, it exploded with electric jolts of sizzling bliss. Diana broke the kiss, threw back her furry head, and howled ecstatically. Sylvie joined in the howl as her own orgasm overtook her. Aglow with erotic rapture, the werewolves stopped even trying to stand up, letting the gentle water of the lake support their weight. For a moment they just floated together under the newly risen moon, content to just revel in each other's company.
After a few minutes of floating and cuddling in the lake, Diana and Sylvie swan ashore. Diana shook her sopping red fur dry, water droplets spraying in all directions. Sylvie did the same, giving her soggy yellow fur a couple of violent shakes until no more lake water was trapped in its mass.
"Whew!" Diana whooped. "That fucking rocked! You were perfect as usual, Sylvie."
"So were you, Di," Sylvie smiled. "Hey, do you think sometime you could introduce me to Selena and hir pack? I've never met a werehyena before, and shi might make for a fun threesome with us."
"Sure thing," said Diana. "Shi and hir friends would love you! Let's be real, who wouldn't?" She gave Sylvie an affectionate lick before they headed back to the pack.
