âSee! Told you they wouldnât be the same size!â
âNoâŚNo way, thatâsâŚThatâs total bullshitâŚ!â You whine. âIdentical twinsâ means youâre supposed to be identical! So why was she so much bigger than you??
Same shape, same color, even the same amount of foreskin. Hers looked just like yours, justâŚNoticeably, significantly larger. Seeing it almost makes you despair.
âLooks like we finally know whoâs the big sister, huh?â She giggled, slapping the head of her cock on yours with a meaty âplapâ. Your cheeks burn red, and you cross your arms over your chest to try and hide. She was never gonna let you live this down, was she?
âS-Shut upâŚ! ThisâŚThis doesnât mean anythingâŚ! You just got luckyâŚ!â Your words sound more and more like girly, pouty whimpers. You look into your twin's eyes, and itâs like staring into a mirror. Your face, your hair, your body - And yet, with her endowment hanging limp between her thighs, she looks undeniably superior to you in every way.
âMaybeâŚâ She slides her cock up against yours, and you can feel the difference in size as it snuggles with your girly bits. She wraps her hand around them both, squeezing them together. ââŚOr maybe I was just born better than you?â
You start to respond, but your own moan cuts you off. She starts to gently stroke herself against you, the weight and friction of her cock dragging along yours, pulling more sweet sounds from your lips. You scramble to rationalize whatâs happening. âYouâŚYou mustâve hit puberty first! Thatâs allâŚIâll catch upâŚâ You pant between whines.
âMmmmhmâŚâ She nods condescendingly. She picks up the pace and strokes your cocks faster, and you feel hers begin to throb atop yours. Feeling the massive chunk of meat flex and twitch against you makes you weak in the knees, something about the virility and power behind it just makes you feel so little and vulnerable. âWhatever you say, kidâŚâ
You pout. âWeâre the same aââ
âHey, shut the fuck up for a secondâŚâ Her voice is husky beneath her breath. It scares you how quickly you obey and fall silent. Sheâs starting to growl, and the way sheâs jerking your cocks grows frantic and hurried. IsâŚIs she gonnaâŚ?
âFuckâ!â She moans. Her cock throbs and spasms violently as it spews cum across yours. It practically paints the entirety of your length, stubborn dribbles still leaking off her slit. When itâs done, sheâs huffing and panting heavily under her breath, collecting herself.
You donât even know what to say. Youâre the same height, and have the same face, and yet, when you look into her eyes, you feel as though youâre on your knees, gazing up at your natural born superior. Your eyes drift back to her cock, and your own, covered in her cum. You see again how much larger and heavier than you she is.
Itâs so unfairâŚWhy did she get to be so bigâŚ?
She takes her leaking head and smushes it up against yours, making an obnoxious kissing sound with her lips. You hear your own voice from her mouth as she speaks through a hazy giggle.
âThis is what a real cock looks like, baby sis~â
