You do.

“No. I'm staying.” You step back from the door and Seigward.

He looks at you in confusion. “Please you don't underst-” He staggers back and clutches his stomach.

It must be true then. He is a werewolf. You place a hand on your dagger and mentally prepare to cast a spell. Seigward falls onto his knees and grunts, frantically crawling to the door under the stairs. He tries to undo the locks and fails as his hands start shaking. You hear him groan and shout 'Leave!' but his voice is becoming deep and raspy. You hear terrible sounds of bones cracking and muscle shifting as his body morphs shape. His arms and fingers double in length, his legs grow and bend backwards at the knee and shin. His shirt rips and tears as he grows, hair bursting from the seams like grass through cobblestone.

When his transformation finishes you see a hunched werewolf. He turns his head and looks at you with his deep yellow eyes. You are ready to defend yourself at any moment, but Seigward doesn't move to attack. You see something in his new eyes. Pain and fear.

“Seigward?” You take your hand off your dagger and slowly raise it towards him.

Seigward grunts and shields himself with his long hairy arm and clawed hand. You expected a werewolf to be a vicious feral creature but all you see in Seigward is a frightened man who is alone. You almost see a bit of yourself in him, when you were younger and dealing with your magical abilities.

You slowly step towards Seigward, keeping your hand out in a friendly gesture. “I'm not going to hurt you and I don't think you are going to hurt me. Am I right?”

Seigward lowers his arm and looks at you again. “N... No.” He answers in a deep voice that seems to vibrate through your body.

You continue to step closer to the hulking mass of muscle and fur that is now Seigward. You can feel the power within him yet also something else; fear and loneliness. You don't think he is a dangerous feral Werewolf, certainly not or else he would be trying to shred you to bits right now. You gently lay one of your hands on his shoulder.

“It's okay. It's okay” You repeat to him as you try and figure out what your next step could be.

“I can't... stop myself.” Seigward cowers against your touch. “I don't want to hurt you. You should leave!”

“Shh. I'm not going anywhere. I'm going to help you.” You run your fingers through his bristly pelage, feeling the soft skin underneath. Your hands roams across his body, tracing his muscles. He is an impressive creature, powerful yet peaceful. You both pity him and feel a kinship.

“I'm... not attacking you, but how?” Seigward cries with a beastly tone underlined with a human gentleness. “You hand feels... nice...”

“Good. It's okay Seigward. Relax I'll figure out how to help you.” You are encouraged by his response to your stroking so you continue running your fingers through his fur. Even going so far as to scratch behind his long ears and under his neck.

Soon Seigward begins to sigh with pleasure at your touch. You find the situation oddly satisfying yourself, like petting a large fluffy mutt! Seigward leans back allowing you to pet his belly which he especially seems to enjoy. Your mind wanders as you pet him as to how you can cure his curse. Geralt must have mentioned something about it during your travels but you just can't seem to recall. You will have to visit a local library to find a bestiary or something.

You look back down at Seigward and you notice something happening between his enormous legs. A soft furry bulb protruding from his crotch starts to shift and expand. You gasp as suddenly a blood red member peaks out and begins to grow. You look up at Seigward's face, his eyes are closed and he is lost in pleasure at your deft hands on his stomach. As you look back his penis is now entirely out of it's sheath and is an inhuman size; there is a round bulge at the base and the head is mostly flat but comes to a point where you see a small slit. It is shimmering with juices and pulsating in an almost hypnotic fashion. You suddenly become keenly aware of a tingle between your own legs as you stare at Seigwards massive hard-on. Am I really getting aroused by a Werewolfs cock?
