“Harder,” I begged.
“You sure? You’re crying.”
“I’m happy to be used by Daddy. Please use me more. Use me the way you really want to.”
With a groan, he shouldered my legs and snapped his hips forward, shoving in deeper. I yelped and clutched the sheets, gripping them into my fists as the thrusts kept coming, stabbing and brutal, one after the other.
My head rolled from left to right on the pillow. It was torture suspended in the pleasure-pain sensations that had taken over my body.
“Sweet boy,” Nils groaned. “My sweet, little boy.”
And I wanted to be. Not the crabby, cantankerous, defensive boy I’d always had to be. I wanted to be his sweet little boy.
“Fuck me, Daddy. Fuck me hard.”
“Yes.” He grabbed a pillow and shoved it under my hips.
“Oh!” My eyes flew open as he slid even deeper.
Nils planted his hands on my hips, pinning me so I couldn’t escape the punishing rhythm he inflicted on my body. I felt like a doll, useless but coming to life under its owner’s touch.
“Shh,” he said in a soothing tone, the soft grunt of exertion coming from deep within his chest, vibrating against my burning flesh. Sweat dripped down his brow, landing on my stomach. A shiver rippled down my spine. “I’ve got you, sweet boy.”
His rhythm was unyielding, each thrust piercing deeper than before, filling me to a point I didn’t know I could reach. A low growl escaped his lips, and his eyes glowed with a feral intensity that made my heart pound irregularly against my ribs.
“Yes, Daddy!” Tears streamed down my face as I surrendered myself to him fully, letting the waves of pleasure control and manipulate my body.
In response, Nils tightened his hold on my hips, fingers pressing bruises into my skin as he quickened his pace even more. His cock pulsed inside me. With one last thrust that pushed me over the edge into blissful oblivion, he filled me up.
I shuddered uncontrollably beneath him as an orgasm crashed over me like a tidal wave. And then… A strange swelling from his cock that pushed into my ass. Screaming, I gripped his arms. This thing locked him to me. We were stuck together.
The big ball pulsed against my p-spot, triggering another wave of electrifying pleasure that cascaded through me. A choked gasp escaped my lips as my body convulsed around him. I couldn’t stop shaking.
“Mine,” Nils whispered, murmuring words in a language I didn’t understand. His soothing voice calmed me until the tremors stopped, and I lay spent on the bed. “There we go. You’re all right. Daddy’s right here inside you. He’s not going to leave you.”
I burst into tears. I didn’t mean to, but once I did, I couldn’t stop. Sobs racked my body, and I wrapped my arms around him, clinging to him.
“Baby, am I hurting you?” he asked softly. “I’m sorry. I was trying to explain earlier, but then you started suckling, and I lost control.”
I sniffled and shook my head. My body was already adjusting to having his swollen glans inside me.
“What is it?” I asked. “I’ve never felt anything like it.”
“It’s called a knot.”
I pulled back and let my head fall onto the pillow. He thumbed away my tears.
“You mean like an…animal?”
“Yes.”
“But why do you have that?”
“I’m an eternal being descended from the yule stag,” he said gently. “I’m the last of my kind.”
“That’s… wild.”
He chuckled. “What do you think? Do you hate it? I could try to force it out, but it’s best to wait until it goes away on its own, so I don’t hurt you.”
