I felt strangely empty as I trembled before her. Hungry . . . thirsty . . . humiliated . . . cheapened . . . used . . . it was like she had stripped away and denied me everything I'd ever taken for granted.

"While being faithful IS important, a successful marriage requires much more." She casual fondled my collar with her foot. "You must learn to obey your wife in all things, to never question or deny her. Now, I never had the chance to teach your father that -- he failed me too early, too often -- but I won't make the same mistake with you."

I wanted to ask what she meant, but had to settle for a meek little whimper. Thanks to an endless succession of tape, gags, and various dildos, Mom had kept me effectively silenced for the vast majority of our time together.

"As I'm sure you've already guessed, you're going to my pet . . . my pretty little puppy. " Suddenly, she laughed. "When it comes to obedience training, nothing beats the harsh simplicity of training a dog -- WOman's best friend."

My gawd, could things possibly get any worse?

Mom gave my collar a quick tug. "Sit," she commanded. "Sit." As I moved to obey, I watched her lean over and slip a hand beneath her pillow. "Good boy," she said softly. "Now, stay." Grinning, she withdrew a realistic-looking 8-inch dildo from inside the pillowcase, making me wonder what else might be hidden inside. Then, with a quick snap, she lunged forward to rip the ball-gag from my mouth.

"Yes, you're such a good doggy," she laughed. "Look what Mommy's got for you!"

I nodded softly, but was unable to fake any kind of excitement. Still, I knew the role I'd been chosen to play, so I pretended to sniff the rubber phallus, investigating it with the limited senses of a pseudo-canine.

"Does the doggy wanna play a game?" She mussed my hair, then reached down to scratch behind my ear. "Do you want to play, boy?"

The instant I began to nod my head, she tossed the dildo across the room. Already dreading the inevitable command to follow, I snapped my head around to watch as the rubber cock bounced once, then rolled into the open door of my mother's walk-in closet.

A few short weeks ago, I would have been shocked by the realisation that my prim-and-proper mother owned any kind of marital aid, especially the dildo that had gone from Dad's ass into mine. Now, though, I found myself wondering what other perverted devices might be hidden deep inside her closet.

"Fetch," she cried. "Fetch the dildo, boy!"

Once again, I scurried across the floor on all fours, mentally preparing myself to wrap my lips around the dildo and return it to her. It wouldn't be the first time I'd taken one of her foul toys in my mouth, but at least there'd be nobody ramming it down my throat this time.

The instant I poked my head inside the closet, I let out a howl of surprise, completely forgetting both my role and the dildo. Trembling, I felt the colour drain from my body as I watched a strange hand reach down to seize my leash.

My gawd, my worst fear had finally come to pass -- we were no longer alone. My humiliation was no longer a private affair. The last taboo had been broken, which meant that from this point on . . . things could only get worse.

"You were right, Wanda -- you do have a pretty pet." Her green eyes shining with excitement, a tall, statuesque blonde woman dragged me back into the light. Naked and sweaty with lust, her average breasts and hairy crotch were a vivid contrast to what my mother had on displaying. Confused and startled as I was, it took me a long moment to recognise her.

It was April - my sister!.....(cont)
