Trini could tell her older sister was staring at her tits. Especially after aging herself a couple years, her breasts had increased in size to that of CC cups just like Sammi used to have. And Sammi wasn't the only one, she was getting looks from teen boys as well.
"Jeleous much Sammi? You keep staring at my boobs." Trini reveled in her sister's envy
"It not all about boobs you know. I still get to wear cute outfits, those things will just get in the way. Besides, guys are into ass more these days, and mines way bigger than yours frog butt." Sammi glared at her younger sister. "Not to mention I'm still taller than you. You're a small fry, still 4'10 and 13."
"Well I wish you were shorter and you had no real curves to speak of." Trini spat at her
"Fat chance brat you may have the tits bu-" Sammi felt her lower half deflate, the room around her was looking bigger too, the next thing she knew, she was eye level with her little sister. "How did-" her mind began to gloss over, memories of being made fun of for her height and the fact that at 16 she might as well been confused for a kid, filled her head. "You're so lucky Trini, I wish I was as beautiful as you." She sunk her head, watching as boys from all around stared at her younger sister, while she, little Sammi, went along practically unnoticed.
Trini mubbled to herself and soon began to grow, her ass and hips expanded till she could sit a Coke can on her back end, her breasts grew even larger, busting out to fat DDs. Her legs lengthened and grew taller, her lips thicker and her hair fuller. She was a drop dead knock out Asian woman standing at her sister's old height of 5'10. "Oh don't worry little Sammi" she bent down a foot to her now much smaller older sister's height. "Im sure you're just a late bloomer. Have you had a boyfriend yet?"
"Noo..." Sammi was both embarrassed and intimidated by her much more well developed younger sister.
Trini laughed in her head, almost out loud. Her older sister always used to have handsome well built guys at their house, but not anymore it seemed. "Here let your big little sister show you how to pick one up."
