You watch in a sort of muted horrified fascination as the werewolves catch up with the two girls in the town center. You actually find yourself almost disconnected from the situation, analyzing it more than anything else. "Hmm," you say to yourself as you watch, "This must be a timeline where we wouldn't have gotten away at all."
You watch as the werewolves take the two of you down, pinning you beneath them. It appears that Becky is even more of a freak than you'd ever suspected, as now werewolf Becky has pinned her previous human incarnation to the ground and thanks to time travel is actually going down on herself and infecting herself with lycanthropy. Not that you're truly surprised, you notice that the human Becky isn't exactly fighting her werewolf-self lover with much effort. Soon enough, Becky from the past is beginning to show signs of transformation as she unknowingly makes bestial love to herself.
Then a twinge hits you right in the crotch as you watch the other werewolf bite your previous self. Your pussy begins to immediately drip musk, and you struggle to stay upright. Your chest begins to heave in and out, straining the fabric of both your shirt and your bra. For a moment, you wonder what's going on, and then it dawns on you- because the previous incarnation of yourself was bitten, the current incarnation is a werewolf. Through no fault of your own, you've now contracted lycanthropy.
You struggle to restrain the animal inside you from emerging, but it's so hard. The moonlight is so very bright, very bright, and it would be so much easier to simply give in, to rend your clothing and join the other wolves in the hunt. But if you can get inside, perhaps you can avoid the transformation....for now.
