Twinning

I looked up at Susan with tears in my eyes, kneeling on the soft carpet and trembling from head to toe.  I'd been bound for days, a humiliating shell locked to my cock, a large steel bulb in my ass, all wrapped up in two pink diapers, one over the other.  All the sass and frustration had ebbed away into timid embarrassment. 

"Please, no more," I begged, fresh tears dripping down my cheeks.

"'No more' she says, after pushing and begging and pleading for this for -years-, don't you think you're being a little bit ungrateful? Don't you think you're being a poor role model for your brother? He'll be home soon, and I know how much you've fantasized about him being a part of your play sessions, how much you've longed for him to be your little sissy sister. What better way to introduce him, hmm?"

"This isn't what I wanted," I muttered under my breath.  She had gone so much further than I ever thought possible.  It was just a fantasy. 

"Please, Su--" 

"Mommy," she corrected, as she grabbed me by the arm and pulled me to my feet.  The thickness of the diapers forced my knees apart and I struggled to stand upright.  I couldn't stop shaking. 

"Please don't... please, please..."

"But this is what you wanted, right? You want your brother to see you this way, you want him to get his little cocklette hard in his pants as he stares at you, you want him to bite his lip and look away, cheeks flushed with potential and possibility. You want to awaken something inside of him, make him your little sister, be pretty little twin princesses, diapered and caged and plugged and so so so helpless." I circled around my prey with a satisfied smile.

As she spoke about my greatest fantasy - my most humiliating fantasy - I felt a tightness against the cage in my diaper.  The plug in my bottom felt heavier as I grew more aware of its presence.  Her words were like calming warm water over the horror of the situation.  Already, I was wearing my frilliest, most embarrassing dress.  If my brother saw me like this... I shook my head and tried to pull myself out of the haze of arousal.  One last effort... 

"Mommy... please... don't..."

"Isn't that the door now?" 

It was, too - the door downstairs, my little charges sibling coming home early to get ready for the hot date with the woman he'd been talking to online; a woman who cultivated fantasies inside of him, a woman he was aching to have the approval of, a woman who was unbeknownst to him, upstairs in his very house right now. But this little sissy right now didn't know any of that, which was going to make this more fun than any of us had ever had. 

"Wait right here, sissy, I'll go get your brother..."
