almost drove me to my knees.
    “Oh... puppy,” he whispered. “Are you sure?”
    I turned and bent over, putting my front paws on the bed, arching my back downwards, lifting my tail for him. Jack had promised we could try this and I couldn't think of a better time.
    “Marie,” he whispered, even more quietly than before.
    I growled, willing him to move before I lost my nerve.
    He stepped behind me, running his fingers through my fur. Then he took hold of my hips and thrust his cock into me. It was like someone was setting fireworks off in my abdomen. Every movement was pure ecstasy. Jack was pounding me harder and harder and I was trembling on the edge of and incredible orgasm when he suddenly lunged forward and wrapped a hand around my snout, holding my mouth closed.
    He pulled my head around so he could look me in the eye.
    “You want to keep the noise down?” he said, panting. “I don't know what the neighbours will think I'm up to in here but it's probably illegal.”
    I snorted laughter. Apparently I was being a little vocal. He released his grip around my mouth and straightened up.
    “Think you can be quiet?” he asked.
    I shook my head. I had an idea, one that I hadn't really wanted to spring on him this quick. Oh well, needs must.
    “Look in the bag,” I said. I hate the sound of my voice in my wolf form.
    I pointed at a piece of luggage by the bed. He stepped backwards and I groaned as his cock slid out of me. He stepped around the bed and bent to unzip the bag.
    He rummaged through the contents with a smile on his lips.
    “ And when were you going to tell me about this, puppy?”

It was a small bag of various things I'd wanted to play with. There was the teeny leather slave bikini I'd worn to that club in Paris not so long ago. There was the collar I'd worn, and the leash. There was a pair of nipple clamps and a nice little vibrator. Some massage oil and a pair of handcuffs and a blindfold and ...
    “Is this a muzzle?” he asked.
    He held up the item he'd found. It was a wide leather strap, fitted to go around my snout, with a thinner leather strap that would buckle behind my head. I nodded carefully.
    “Think this is going to work?” he asked. “Is this going to make you a quiet puppy?”
    “ Shut up,” I growled, “and fuck me.”
    “ And what makes you think you're giving orders here, puppy?”
    I shut my mouth and tried not to grin.
    “Shut your eyes, puppy,” he snapped.
    I obeyed quickly. He stood up and stepped behind me. His cock ruffled the fur on my thigh has he bucked the muzzle in place. My mouth was firmly held closed. Then he tied something over my eyes. It felt like one of the strips of silk I'd put in the bag. Then he buckled something around my throat. My collar. The one he'd given me in Paris.
    “Get up on the bed,” he ordered. “Lay on your back.”
    I scrambled up and turned over.
    “Open your legs.” I did so. “Wider.”  I spread my legs further apart. “ Wider .”
    I hooked my heels over the edges of the bed.
    “Better.”
    The bed moved as he climbed on between my thighs. He took one of my hands and wrapped something around my wrist, then he pulled it over my head. I took a deep breath and swallowed. He was tying my wrists to the headboard with more of the strips of silk. When he was done he ran his fingertips down my arms and across my breasts, gently tickling my nipples.
    “Now, that's better,” he said softly.
    He leaned down and kissed me on the nose.
    “ Now I'm gonna fuck you.”
    He moved around for a few seconds and I felt his hands on my hips an instant before his cock pushed into me. With the muzzle on I couldn't cry out at the sheer pleasure of the feeling. All I could manage was a soft whimper of joy. Being blind, mute and restrained was intoxicating. It amplified the effect of every thrust. It felt like he was shoving that cock so far in that it would hit the back of my throat. With the blindfold on I lost all sense of time. The whole world
