Jenna followed Tatiana into a large and opulent bedroom filled with priceless antique furniture. Instead of a bed, a richly carved coffin occupied the center of the room. Inside the coffin, two inhumanly beautiful alabaster-skinned women were enthusiastically fucking each other. One was a tall, regal woman with lustrous raven hair. Her partner was a smaller woman with soft blonde hair. The dark-haired one wore a harness with a carved diamond dildo strapped to it. She paused from ramming her strap-on into the blonde to look at Jenna and Tatiana.
"Welcome back from school, Tata," the raven-haired vampire in the strap-on said to Tatiana. "Who's your friend?"
"Momtriarch," Tatiana sighed, "I told you not to call me 'Tata', especially in front of my friends! My friends call me 'Tats'. I'll accept 'Tatiana' or that. Anyway, this is Jenna McSweeney. She's a new member of Selena's werehyena pack."
The raven-hared vampire pulled her strap-on out of her lover's pussy, stood up, and hastily attempted a curtsy. Curtsying in the nude was a little weird, but the vampire somehow managed it. "Greetings, Jenna McSweeney of the Stokerville werehyena pack. I am Carmilla von Karnstein, matriarch of Clan von Karnstein. You have the hospitality of me, my bride, and my clan."
The blonde then stood. She also attempted a nude curtsy, her cheeks blushing blue with bashfulness as she caught Jenna's awkward expression. "Hello, Jenna. I am Mircalla von Karnstein, formerly Laura Hollis. I am Matriarch Carmilla's consort. You are my honored guest, and your wish is my command unless it should violate the will of my bride and matriarch."
"Th-thank you," Jenna responded. "Oh, don't think you have to stand there looking at me. Feel free to carrying on with your, uh, fun."
The clan leaders nodded. Mircalla laid herself down flat on her back, and Carmilla thrust her strap-on back into her consort's dripping pussy. "So, Jenna," Carmilla said as she began to piston her hips back and forth, "why don't you tell us a little about yourself?"
"Well..." Jenna mumbled, having trouble focusing on her thoughts as she watched Carmilla and Mircalla passionately fuck right in front of her, "I've, uh, have this massive crush on Selena Lyall for years, but I was always too shy to say anything. But things took a really wild turn today. Selena told me that she's the alpha of a werehyena pack... and she wanted me in it! What's more, she wanted me to be her honest-to-Christ mate!"
"But I thought Selena and Tatiana were dating," Mircalla said between aroused moans.
"We are," Tatiana explained, "but Selena needs a living, fertile mate to help her pass her genes on. We're still together, of course; werehyenas can have multiple mates, depending on the rules of the individual pack. As a matter of fact, I've been falling in love with Jenna myself."
"How lovely!" Carmilla smiled as she pounded Mircalla's yearning cunt. "I've occasionally met vampires with more than one soulmate. Do carry on, Jenna."
"Selena turned me in the gym after school," Jenna said, her eyes still glued to Carmilla and Mircalla's lovemaking. "She was also turning the rest of the girls' basketball team, along with my friend Hannah and a girl from Drama Club called Lily. I think I surprised them with my werehyena form."
"How so?" Carmilla asked as she increased the tempo of her thrusts.
"Most of them are really buff amazons," Jenna explained. "But my body's all voluptuous softness and curves. Just take a look."
Jenna hastily stripped all her clothes off and willed her body to shift. Her thick pelt of fur bloomed all over her body, and her feminine attributes grew and rounded as her skeleton took on a more hyena-like shape. Finally, hir clit swelled into a mighty cock as a hefty ballsack dropped beneath it. "See what I mean?" Jenna smiled. "I'm a horny furry's dream come true."
"You do look quite different from Selena," Mircalla remarked.
"They were surprised by my body, too," Jenna said as she returned to her human form and got dressed. "It caused the pack to realize that I'm a different kind of werehyena than most of them. I'm what's called a breeder, a werehyena optimized for, well, breeding. Selena says she's going to have to be really careful not to cum inside my pussy to avoid getting me pregnant before we're both ready. After everyone was done transforming, Selena invited us into the woods on your manor's grounds for some sparring matches. She said it'd help determine pack status."
"And how did that go?" Carmilla asked, lovingly stroking her consort's pearly breasts as she passionately thrust into her with supernatural speed and grace.
"Okay, I guess?" Jenna shrugged. "Abbie Peterson took a nasty blow to the jewels, but Morgana might be able to help. Aside from that, everything was sorted out. I'm a gamma, but that's good with me; I've never been a take-charge type. After the sparring wrapped up, Tatiana invited me into the manor so she could bond with me as a mate."
"If you know what I mean," Tatiana giggled, winking at Jenna.
"What a lovely idea!" Mircalla said. "I hope you enjoy your visit, Jenna."
At that moment, both vampires climaxed. Carmilla and Mircalla cried out with inhuman, bat-like screeches of pleasure as Mircalla's pussy clenched around the diamond strap-on. The two vampires shuddered as the orgasmic bliss pulsed through their immortal bodies. Finally, they let themselves go limp, lying in a pile of cold, ivory flesh and savoring each other's presence.
As she watched the vampires' orgasm, something strange occurred to Jenna. "Say, did both of you guys just orgasm? Can you... feel through your strap-on, Carmilla?"
Carmilla chuckled. "As a matter of fact, yes. I bought this strap-on dildo from Morgana's Services for the Strange. It's enchanted so that I can feel through it as if it were my actual penis."
"Cool," Jenna said admiringly.
"I have one of those, too," said Tatiana. "Come over to my room, and I'll show it off for you... and give you a demonstration."
"Sounds great!" Jenna said with excitement. "Bye, Carmilla! Bye, Mircalla!"
"Farewell, Jenna McSweeney," Carmilla waved, smiling fondly at the young lovers as they raced off to Tatiana's room to indulge in their own lovemaking.
