Vivian
I pad down the hall and into the bathroom. As I pass Liz's room, I poke my head in to wake her up. I'm surprised to see an empty bed; Liz almost never wakes before I do. Shrugging it off, I proceed with my daily morning routine.
As I brush my teeth, I hear a strange scuffle from my bed room. I spit and rinse, then head to my room apprehensively.
I peek inside and see Liz going through one of my drawers. She is topless and is holding her chest strangely. I clear my throat. "Liz?"
She yelps and turns around, her other hand jumping to her throat in shock. "Viv! I, uh..."
"What happened to you?" I ask in shock.
My little sister has never been especially "gifted" by Mother Nature, with smallish hips and a max size B cup. Now, though, her pajama pants' elastic is stretched to the max on her distinctly hour-glass figure, and she is clutching her perky D-cups (if not bigger) to keep them from weighing her down. Her face looks slightly different too, older almost. I stare, trying to understand.
"Um..."
"Did someone give you pure estrogen or something?" I don't try to approach her, still in shock. This isn't natural.
I feel guilty for my shock when tears rim Liz's eyes. "I don't know, Viv! I didn't sleep well last night, and when I woke up, I had... these!" She motions to her breasts. "Now none of my bras fit, and I hoped to borrow one of yours."
"Liz, of course you can," I reply, using a soothing voice. "You don't need to sneak around though." I look at her chest again, thinking. "It may be a tight fit, but we'll make it work. I'll take you clothes shopping later though, I promise."
"Thank you," she whispers.
I rummage through my drawer and pull out my biggest bra. It is somewhat frilly, so I feel awkward and embarrassed to be giving it to my little sister, but she is too distressed to notice. I help her clip it on. When I do, I see a strange mark where her neck meets her shoulder. The mark reminds me of the stereotypical snake-bite; two round holes like scars. It is shiny, with a golden shimmer to it. "What's this?"
My little sister stiffens and evades the question. "Viv, I think I'll need to borrow a shirt too. I doubt mine will fit."
Given her chest is still sort of bulging around the bra, I doubt mine would even fit her. We find a large T-shirt that toned down her sudden change (though I still think it is glaringly obvious, Liz is pleased so I don't say anything). Then we discover she would need to borrow one of my pants, since her hips and butt are too big. After that, we realize she had grown a good two or three inches, almost to my height, but the pants still show too much ankle somehow. It is like her legs turned to the laws of human anatomy and said a hearty "Fuck you!" I give her a skirt instead, so it would be less noticeable. I worry it makes it more noticeable, but my sister doesn't want to wear the jeans.
"Thank you," she says again. "I appreciate it, Viv."
"Not a problem, sis." I give her a smile, but I know my eyes still convey concern. "Liz... You would tell me if you had gotten mixed up in something right? If you started, I don't know, doing drugs, or get in a relationship with someone?"
She returns the smile, albeit a stressed one. "I highly doubt those two examples are inherently related."
I blush a little. I persist though. "You'd tell me though, right? Promise?"
"I promise, Vivian."
"Good." I ruffle her hair, only just noticing how suddenly smooth and lustrous it is now. "Finish getting ready and let's go to school."
