"Alright," you tell Joy, already eager to jump into the cage, not worrying about the rest of your human life.
Joy opens the door, and you step eagerly through. Anna smiles at you, stroking your face. "My pretty one," she says tenderly,"are you ready to join me?"
"Yes," you reply, quivering anxiously.
Anna turns to Joy,"Turn the lights back up, but softer. I need more control now."
Joy nods, turning the lights up to half of the intensity that they had been during Anna's first change. Anna's eyes immediately flare in the feral way of the beast, but her muscular tremors are far less severe.
She drops to all fours, raising her ass up to you, her quivering mound sprouting fur slowly, her vagina shifting and pulsing. You slide your cock in, eliciting a howl from Anna, a low, pleasure-filled moaning howl.
You practically don't have to thrust in Anna, as the quivering of her sex gives you a tactile sensation you've never felt before. The fur blossoming on her ass and thighs tickles your balls as it grows, intensifying the sensations a hundredfold.
You begin to thrust reflexively, and she counterthrusts with you, her changes coming quicker as the pace of your fucking quickens.
You erupt within her as her muzzle snaps outward, and her tail blossoms into your face. She lets out a deafening howl, and you collapse, falling out of her. The werewolf rises on her two hind legs now, hovering over you, infectious saliva dripping from her maw.
You realize now that you've volunteered for a life-changing event, and momentarily, you have a second thought, slightly afraid that Anna might kill you.
