While Isabella and Raquel hadn't bitten anyone, Brianne had. Just as Trisha had explained to Cynthia, anyone who their packmates had bitten was also subject to the same level of change contagiousness as a direct packmate.
While most of the girls managed to keep their fangs under control, Brianne had never been the best at controlling her urges. Even as she'd alerted her cabin mates to her impending change, she'd been eager to give in, despite her apparent reluctance. Everything she'd done in front of them had been designed to get at least one (if not all) of them to change with her. Even though she appeared to be fighting the change, she'd been tensing her kegel muscles, consciously trying to force more musk and pheromones out. Simply put, her wolf side and her sex drive were too strong for her own good.
She'd been bitten the previous year by Trisha and Kaitlyn, and after a summer spent seemingly having endless sex and discovering that yes, she definitely was at least bisexual, if not strictly a lesbian, that year had left her feeling lonely. Over the next eight and a half months, she attempted to sate herself by the occasional skype session with her pack, where they'd video conference with each other and watch each other change. There had also been a couple of wild weekends with pack members, but as they were in college and scattered across the US, coordination was a problem.
As the months had gone on, her sex drive had continued to crank up higher, and she found herself insatiable. She needed another person in her bed; her fingers and toys could no longer do enough. That was when she met Arianna. Arianna was beautiful, six feet, four inches tall and athletically built, with long blonde hair and sparkling blue eyes.
She'd met her a few days after the last full moon, and there had been chemistry. While Brianne was willing to hold off until at least Trisha could come meet her, it was obvious that Arianna was attracted to her. She constantly made flirtatious comments, and complimented Brianne's body. As the days went on, she found herself getting wetter and wetter, and the urge to turn Arianna grew. When Trisha said she couldn't make it out, Brianne's heart sank, but her desire remained unwavering.
Still, she couldn't begin to think of how to explain to Arianna what she was, without driving her away. And so she waited, letting her animal side grow stronger as the moon started to wax closer to full, and invited her over to her house the night of the full moon. Timing everything as best she could, she let nature take its course, and with one carnal experience, Arianna found herself more than human.
Unfortunately, Brianne hadn't given her the talk, wanting to let Trisha do it, but Trisha had been finishing up finals, and didn't have the time. So Arianna had no idea that change contagiousness was something that could happen, or why it would. She'd only been a werewolf for one complete lunar cycle, and now the only werewolf she knew was away, working her summer job.
And now, due to Trisha's carelessness (understandable or not), and Brianne's inability to control her impulses away from the pack, Arianne began to feel something inside herself beginning to stir.
