He takes over for you

With a dazed head, and struggling lungs, you quickly find yourself losing to his survival instincts. In a flash, he had pinned her on her back, your hairy body overshadowing her dainty form. With fearful eyes, she managed to let out one pitiful 'please' before he shoved his cock once more into your sister.

Except this time was different. For the first time you were aware during one of his transformations.

And what you saw through his eyes was disgusting.

You were **** to watch as he **** Sarah, the only family you had left. His claws leaving bloody scratches as he sought to teach his bitch a lesson. As he sought to teach you a lesson. Tears streamed down her face in resigned acceptance of her tormentor. Her choked sobs echoed through the forest alongside the slaps of wet flesh and canine grunts. You tried to stay as numb to the sensations flowing through his.. your body, but you couldn't deny them in the slightest.

In record time, you could feel his orgasm as he slammed his cock home and began to swell inside of Sarah. As the bulge at the base of his cock locked inside of her, you understood what she must have meant by 'knotted'. Tugging twice to confirm the situation, he then released the floodgates, and began to cum a truly monumental amount. It wasn't one massive orgasm that you knew from your own body, but rather a number of smaller beats of pleasure centered around each pulse of his member, echoing back through his body to your mind.

When he feels satisfied that you would not attempt to flee from this encounter, he releases his hold on your body, leaving you locked inside this disgusting form, which was, itself, locked inside of Sarah. You tug at the connection with your hips, and feel that you are truly stuck together. With every pulse of your member sending a fresh set of endorphins to your brain, you are left with few options, and decide to simply lie down and provide her with your warmth.

Resting on your forearms brings you much closer to her face, and some instinctual part of you tries to comfort your sister by licking away her tears. At first she shies away from the touch, but after a moment she looks up to you with concern in her eyes. She breathlessly whispers your name, and seems to find some comfort in your eyes. She wraps her hands through your fur and pulls your warmth further on top of her. Your embrace is sweet, if not gentle, as she cries into your shoulder, simply pleased to no longer be alone.
