I gripped the back of his head with my free hand and threaded my fingers through his hair.
"You're going to stay just like that," I said. "And I'm going to use your mouth however I want. And you're going to let me. Aren't you?"
Diego moaned around my cock. It was surrender. The vibration went straight through me, and I had to bite back a groan.
The blade stayed at his throat. I pulled out slowly and fed back in, shallow at first, testing. Diego relaxed his throat and opened for me.
I went deeper. He took it. The wet heat of him tightened around my cock and I locked my jaw so hard my molars ground together. He just knelt there and let me use him while the blade held steady against his throat and my hips took over the way my hands did when I held a weapon.
My shoulder burned with every thrust, the stitches pulling against swollen skin, but the pain just folded into everything else. It all blurred together: heat, ache, the taste of smoke in my throat, and under all of it the want to hurt him so bright it scared me.
I ashed the cigarette onto Diego's shoulder. The gray smear landed on bare skin, and he took it without flinching.
"Good," I said. "That's good."
Diego knelt with my cock down his throat, my blade at his neck, tears tracking down his face. He stretched around me, cheeks dark with flush. I needed to wreck him worse. I needed to keep him exactly like this forever.
I could feel his pulse hammering through the steel, fast, desperate. My own pulse matched it. I was already too close.
"Touch yourself," I said.
Diego wrapped his fist around his cock and started stroking slow.
The blade trembled in my hand for just a second.
A thin line of red appeared on Diego's throat.
I froze. The cigarette fell from my fingers.
I'd cut him.
Diego kept his eyes on mine, kept his mouth around my cock, kept his hand moving on himself.
Blood ran down his throat in a thin trickle that disappeared into the hair on his chest.
"Diego." I cracked on it. "I cut you. I fucking cut you."
He pulled off my cock just long enough to say, "I know." Then he took me back into his mouth, deeper this time, all the way down until his nose pressed against my stomach and I could feel him swallowing around me.
I throbbed so hard that it hurt.
I gripped his hair tighter and stopped thinking. I just took what I needed while the blade pressed against his bleeding throat. Diego stroked himself faster, rocking forward into his own fist.
"I'm going to come down your throat," I said. "And you're going to swallow every drop."
Diego whimpered.
I buried myself in his throat, and he swallowed around me, and that was it.
The orgasm tore through me. I locked my knees, locked my grip on the blade, locked everything down while my cock pulsed and Diego swallowed. The only thing holding me upright was the muscle memory of a man who'd been trained never to drop his weapon. He took all of it. He took everything I gave him while I held a blade to his bleeding throat and came apart above him.
When it was done, I pulled out slow. Diego gasped for air, lips swollen and slick, blood still running down his throat.
I brought the cigarette to my lips, but it had burned out. I dropped it and ground it under my boot.
The blade was still at his throat.
"Stand up," I said.
