Emily now dwarfed your nubile little body, and you could feel her thin, soft fingers teasing the entrance of your puffy little slit under the waistband of the male boxers you still wore.
"What a shame that you've turned yourself into a girl... Now, you're just the same as me. Cockless and needy hmm?" Your once-little sister says, her finger pressing more insistantly against your vulnerable little lips as you squirm. "Can you even remember what it felt like to a have a penis sweetie?"
Your memories were all jumbled. On one hand, you remembered growing up a girl, with your older sister being your Protector, best friend and, recently, your lover and your guide to your budding sexuality since you shared such similar yearnings and fascinations... But somewhere in your mind, you also remembered your old life, although it felt much more like a fading dream than your memories of life as a girl.
"I... It's hard to remember. I know I should know what it feels like to have... Uhm... A boy's penis." you say, blushing as if the word was unfamiliar and humiliating to you. "But I... I have trouble remembering." you admit sweetly, trembling with pleasure as your sister teased you with her fingers.
"What a pity.... I could be holding a real penis right now..." her teasing tone is paired with a strange sensation as she suddenly spreads your lips and puts two fingers on each side of your tiny little clit, moving them up and down as if she was stroking a real cock.
"... But instead, you're now stuck with this. Same as me... A tiny little clitty, too small to even make the smallest bump in even the snuggest of panties." She says, panting alongside you as the things she says to tease you seem to affect her equally.
As if by pure instinct, you let your own hand slide down her tummy, and pull down her panties, letting your young fingers explore your sister's needy sex, finding it just as soaked as yours was. "Oh? And what about you? You think you're any better? You think your humiliatingly tiny little nub would be able to do better than mine?" You whisper in her ear as she presses her body against you with desperate desire.
Both of you were slaves to your own new desires, and as sisters who shared the same shameful kink, you knew exactly how to turn the other into a mewling, wet, needy mess.
Emily moaned. "A-and you think you're fooling anyone? Wearing boys boxers that you can't even fill? Does it make you wet to be reminded how inadequate you are every time you move, how cockless you are? Do you wet your boxers feeling them rub between your thighs, K-knowing that you'll never be able to fill them? "
" Aah! " you squeal cutely, unable to summon up any words as you buck your needy little hips against your sisters fingers, and feel her doing the same to your own.
Both of your breath whimpers become more chaotic and uncontrolled as you finger each other desperately, until you feel the pressure that built below your abdomen threaten to release. You cry out, feeling the muscles of your nubile sex quiver and squeeze your sister's fingers, while she does the same to yours, cumming together almost at the same time...
