The Alpha King's Cursed Luna

I found my fated mate covered in welts and needle marks, wolf-less, and reeking of chemicals when I first took her back to my pack.
She was lying naked on my bed, and I was applying ointment to her...
My erection strained painfully against my pants, the outline clearly visible and substantial. Her green eyes fell on it, curiosity replacing fear.
"What's that... stick? Why do you have a stick in your pants?" she asked innocently, her eyes fixed on the bulge.
I froze. My wolf Luca roared with laughter in my head. She doesn't even know what a cock is!
She tentatively reached out, her fingertips brushing against my jeans. "Do you want me to help you take it out? Because you look really uncomfortable!"
Luca was losing his mind with laughter in my head.
"Don't," I warned, my voice dropping to a growl.
"Oh! Did I hurt you?" she asked, confusion and concern clouding her features. "What's it for?"
Oh my God, she is killing you, dude! Luca snickered.
"When I want to mate with someone..."
"With me? You said that I was your mate." she asked in a small voice, but without fear.
The innocent question nearly made me lose my last shred of control. "Yes, with you," I admitted hoarsely.
How was she not embarrassed at all during what should have been a mortifying conversation?
God, my cock was so hard!
I discovered that she seemed to be hiding more secrets... This Luna with an unknown background is really giving me new challenges!
