With your new, girlier and hornier little sister shamefully humping a stuffed toy inches away from you, you couldn't think straight. You wanted to tease her so badly, hear the humiliating little whimper she made as you titillated her new fetish.
"It's not your fault you lost the genetic lottery and was born with a silly little slit between your legs rather than a big, powerful cock like mine. It could have been different too, if you had just kept the veil, but no, you were too weak and too girly to keep it to yourself. If you had, you could have inverted everything. Can you imagine it Emily? Of course you can't. Not anymore. Now you just want to be reminded how much of a cockless little girl you are..."
You slipped a hand under your pants to grab at your throbbing erection. Your little sister had closed her eyes, mewling like a kitten, hands on her petite budding breasts as she rubbed her clit against her stuffy. " More... Please. " she squealed.
" Yeah. If you grabbed that veil now, you wouldn't even turn yourself into a man, or do anything to me... You're too obsessed by your own girliness and how wet it makes you. You'd just grab the veil and say I'm an even smaller, even girlier girl. I'm so desperate to have a penis but, in reality, it's because I love to be teased about how girly I am. I'm obsessed by men teasing me, talking down to me and making me feel helpless, vulnerable and feminine... And... Oh... No no no! "
Too late did you realize the words you said while holding the veil, and already, you could feel yourself shrinking down into your clothes. Your hand, stroking your erection, suddenly felt dainty and soft, while your erection felt smaller and thinner with every pump...
New desires rushed in your mind as you felt little breasts start to bloom on your chest, and remain shamefully small. Impossible memories filled your mind as you dwindled into a humiliatingly feminine and much younger version of yourself...
You remembered as a young girl begging your friends to 'show you theirs if you showed them yours'. You remembered feeling so impossibly jealous when one of them did show you: the extra appendage that boys had been blessed with felt so unfair to you!
You remember going up to your mommy, asking her when would your penis grow, and her awkward reaction as she tried to explain to you that it wouldn't happen to you. That you were just a little girl, and little girls didn't have penises.
You vividly remembered how strange and tingly her answer made you feel as you excused yourself and locked yourself in your girly bedroom, undressing in front of the mirror and looking at your humiliatingly flat crotch. The delightfully shameful sensation you felt as you knew that you'd never be a boy's equal, that you'd never had that beautiful penis that haunted and obsessed you...
You remember going to Emily, your big sister, confused and in tears, explaining to her what you were feeling and how you didn't know why it felt so good. Emily, recognizing in you the exact same obsession she had when she was little, gently explained that you were like her: obsessed with penises but even more obsessed about how you felt when you were talked down to for not having one, teased and titillated for being a silly girl.
Those explanations and hearts-to-hearts would soon turn into sessions of teasing one another, reminding each other how small, how girly and how cockless you both were, fingering each other under the covers of her bed while both spiralling deeper and deeper in your obsessions.
You snapped back to reality, looking at your weak and dainty little hands, still idly pumping where your cock once was, as if you were a boy. What a silly thought!
