You come in to a surprise, as you see your girlfriend almost fully transformed, as she has her fingers in her cunt, howling while groping her breast. She opens her eyes to see you, and yips in fear as her changes finish.
"Katherine? Is that still you?" You ask in fear, only to find relief as she nods. Thank goodness, there are some werewolves who don't lose their humanity. "But...does that mean all of those bite victims will transform too?" She nods again, and gets up, her fur quite beautiful in your eyes. Wait, why were you thinking that? She rips off your clothes, and both of you are surprised to see that your cock was now red with a knot, and brown fur was growing around it. You remember someone accidentally biting your shoulder at work, and you suddenly realize that that person must have been bitten! "Katherine, can werewolves speak to each other?" She nods, and starts to growl slowly, as you begin to hear her voice again. "...love you." You blush as the first covers your whole body. She lifts you up and puts you on the bed, and wastes no time in fucking you. As she slams her vagina around your cock, you feel yourself growing bigger, to become slightly bigger than her. "Grrgh...time to fuck!" She starts bouncing up and down on your cock, as you grow claws, a tail, and a wild attraction for werewolf bitches. "F-fuck yes...Katherine, you're so fucking hot..." You meant that in two ways. 1. because she was a beautiful werewolf, and 2, because her pussy was hot.
