Mark watched Jack reluctantly bow at his feet.  Keeping his foot on the leach to hold Jack there, he reached down to lay his hand on Jack's back.  The fastest way to train Jack was to train him the same way he had trained Chica... only slightly different.  Mark slowly drifted his fingers along Jack's spine to his raised tailbone, trying to stay commanding but gentle as he told Jack.  "Very good. Now stay still".  Mark tested how well Jack was listening by letting his middle finger slide down the creak of his ass.  Keeping a close eye on Jack's every move.  Goosebumps formed along Jack's legs and his muscles flexed... but he didn't move around.  At least until his finger slid over his asshole, when he shifted his weight forward to press his neck against Mark's leg.  The leach restricted him from really going anywhere else.  Mark adjusted his finger back to rub Jack there, watching him lean harder into his leg.  He was pinned.  Unwilling to back up and unable to move forward. 

Jack wasn't without his surprises though.  As he set the tail down to grab the lube off the edge of the bed,  Jack shuffled sideways away from him.  Mark rolled his eyes, kneeling down  on the floor with his foot still firmly on Jack's leach.  Wrapping his arm around Jack's raised hips, he tried to pull Jack back to him.  Jack twisted and dropped flat against the floor, instantly making Mark unable to get a good enough grip.  Glancing down at Jack's muzzled face, he asked him curiously.  "Jack... Are you sore there"?  Jack shook his head, mumbling out slightly playfully.  "No, Master".  Mark sighed, before asking him with soft annoyance.  "You enjoy making this harder on yourself"?  Jack's striking blue eyes turned to look up at him as he answered smugly defiant.  "No. I'm making this harder on 'you', Master".  Mark stared down Jack a moment, a small smile spreading across his face.  Just like a dog.  All that energy and no outlet.  Turning his gaze to the lube bottle in his hand, Mark pried off the cap as he answered Jack smugly.  "Is that what you think"? 

Mark squeezed the bottle, coating his middle finger for Jack to see.  After setting the bottle aside, Mark quickly leaned forward to snatch Jack's arm.  Jack tried to shift his weight away, but Mark easily pulled him around enough to wrap an arm around his waist and pull him the rest of the way.  Keeping ahold of Jack's thigh, Mark slipped his lubed middle finger back into place.  He could feel the lube working on his finger.  It made his finger feel so warm.  Jack jerked, but it was utterly useless.  Mark had him completely pinned now.  Mark's hand soothingly stroked up and down the inside of his thigh as his finger smeared lube over his asshole.  The lube felt like Mark was cheating!  It worked within seconds of touching him.  Warming his asshole up, until it relaxed on it's own!  It felt so good that his whole body wanted to feel that way.  Jack felt Mark's finger leave and watched him pick up the tail off the floor.  Taking a deep breath, Jack waited patiently for it.  It was bound to happen, right?

Jack closed his eyes the second he felt the rubber press slowly into his ass.  Stretching him wider and wider as it entered.  This one felt strange though.  Longer?  It was hard to say, because Mark had lubed it up and he could feel the warmth filling his ass and curling his toes!  His body seemed to know something his mind hadn't caught onto yet... and he felt it!  The tip of the anal plug brushed against his prostate gland, smearing that incredible warmth over it.  The pleasure was so intense that Jack's eyes rolled and his body stiffened up.  He was ready to cum right now!  Only nothing came out of him... and Mark was quickly buckling something around his waist.  Jack shifted trying to figure out what Mark was doing.  Only to have Mark tell him, sarcastically.  "Oh, I'm sorry? Did I stop you"?  Mark removed his foot off the leach and Jack bolted up onto all fours.  Peeking between his legs to see that Mark had fastened a belt around his waist that not only held the tail firmly in place... but had come with a metal cock ring! 

Mark scooted back to lean against the side of the bed, watching Jack with a smile.  Peeking between his front paws like a curious pup as he discovered his tail.  Jack's head shot up a moment later, his eyes narrowing on him in frustration as he snapped at him.  "What the hell?!  Take the ring off"!  Mark shook his head defiantly as a response and Jack straightened up on his knees to unbuckle the belt... only to realize he couldn't.  The paw gloves didn't give him access to his fingers.  Slowly sinking back to all fours, Jack suddenly became sweet and playfully.  Bowing playfully like a dog and swinging his long tail back and forth behind him as he asked Mark.  "Please, daddy"?  Mark reached up to pull the last thing off the bed.  A smug smile spreading over his face as he told Jack.  "I forgot to mention that this punishment is actually a two for one. See, while you're learning to be a good dog... there is a small catch.  For every time you demand something of me... or forget to call me a title... I will do this". 

Jack straightened up on all fours, his eyes widening as he realized what was in Mark's hand.  The smug smile on Mark's face turned wicked as he pressed the button to a small wireless remote.  Jack closed his legs up tight, but it didn't help... it made it worse!  The anal plug was vibrating right against his warmed up prostate!  Jack dropped to his side on the floor, moaning loudly as his body desperately wanted to cum... but the cock ring wasn't letting him!  All he could do was lay there panting as his cock throbbed and ached for release!  When the anal plug finally shut off, Jack could only lay across the floor panting as Mark walked over him.  Mark leaned down to brush his green bangs from his eyes.  Then he unclipped the leach from his collar, casually asking him with pride.  "Still think it's harder on me, Jack"?  To Be Continued...
