A shorty I spit out for ya. I filed this one under "Incest" while it leans really heavy on "Exhibitionism". It is absolutely 100% soft-core, ending for some of you where you probably want it to pick up. If that kind of teased ending bugs you, please move on. I may continue with this story later, however, as I've been pretty random about which stories I pursue. Hope you enjoy. Cheers!

"Charlie, can you turn off the TV and talk with me a minute?"
My sister was dressed in a long tee, with likely little underneath, I thought. Typical evening wear for her lately, even though her unrestricted c-cup mounds bounced and jiggled freely under the loose fabric. I had gotten used to it, even though she once used to be much more reserved.
Harley was my twin. We grew up in a modest trailer, under the guidance of a single, struggling mother. Dad never paid child support, and Mom did her best to manage the expenses of a three-unit household, on a low-wage job. Harley and I shared a room all the way through high school. Scrimping and saving, we afforded an apartment together while attending college these days. Considering we were so accustomed to close-quarters living, the move to our own apartment was an upgrade, and Harley and I got along better than ever.
Harley had a full ride academically, and only needed to work a few hours a week to help pay the bills. She had always been the brainy one, while I was more the athlete. Unfortunately, a shoulder injury ruined my opportunity for a tennis scholarship, and I had to accrue loans and more work to help keep up. Harley was always kind enough to help me with my class work, even though it was simpleton stuff for one with such a higher-functioning brain. Ever since she was five, Harley had her head buried in books, from philosophy to history to math. She had a particular fascination with Quantum Physics, which was all way over my head.
During the last half of our senior year in high school, my sister's body began to change, rather rapidly. What should have occurred in her early teens belatedly hit her, and by the time we started college, she was maybe a full B-cup, or a C-cup. Prior to the physical change, Harley had the stereotypical body of a hyper-smart, book nerd, but now she was beginning to develop the body our mother possessed in her early 20s. From old photos and Mom's own testimonials, we knew Mom was a free-loving hippy prior for much of her young adulthood. After giving birth to us, she settled down to be as good a mother as she could be, while Dad supposedly roamed the country avoiding responsibilities, and any semblance of a stable lifestyle.
Harley and I had only once had a discussion about her physical changes. It was the summer prior to our sophomore year of college. She claimed she didn't really like what was happening to her, or understand it, she admitted she got a lot more attention from guys at school. Most guys bored her immensely, I knew. I thought maybe Harley had been bouncing the idea around of dating at the time - something she'd sworn off, until after she graduated - but now, almost two years later, my sister still wasn't dating, and she'd never brought up the subject again.
Using the remote, I switched off the TV and then leaned back against the couch. Harley stood in front of me. With the light shining behind her, her figure was silhouetted under her long tee. Anyone else, and I likely would have gotten aroused.
"Charlie, I had to get fitted for a D-cup bra today. They're still growing. I'm not doing anything, and my body won't stop developing. I'm afraid I am going to have a see a doctor or something!"
"I'm surprised you haven't already," I said. "I figured you've read up on everything there is about late bloomers."
Harley crossed her arms. "I have. It's rare, and it's not just that. It's really... well... bothering me. It's distracting. I used to get so much more work done before..."
"What do you mean?"
"Well, come on, Charlie. If your body started sprouting, and you started getting bigger or fatter - or turning into some god-like Adonis, for that matter - you'd be preoccupied with it. Look at this from my point of view. I'm not eating differently, acting differently, or doing anything. I'm just going through some strange kind of late puberty. I probably stand an hour a day in front of the mirror just trying to make sense of it."
I'd never thought of the consequences, but it wasn't a stretch to imagine. Harley's physical changes were unique, and while they were practically unnoticeable from day to day, it was a rapid change over the span of just a few years. I was beginning to feel very sympathetic to my sister's plight.
"But... lately, there's something else. I mean, I shouldn't be telling you this, but I think I have like a heightened libido or something. Especially recently. All the time, I am just horny and it's driving me nuts!"
If there is one thing I knew about Harley, it's her rather jilted attitude towards sex. She just never mentioned it or thought much of it, at least when we were growing up. If I didn't know her better, I would have thought she was practically asexual. This 'heightened libido' was surprising news to hear.
I eyed Harley, looking at her now, and thinking back to just a few years ago when she was a skinny beanpole of a nerd, always wearing a flannel shirt and baggy shorts. "I have to admit, you have gone through a lot of changes. Your ass looks like it is filling out, too. I had a friend ask if you were getting work done."'j
Harley smirked. "You're not the only one being asked that. It's insulting. As if I would want the body of a bimbo? And my ass isn't getting fat, it's just lifting up and getting firmer. It makes no sense. One should have to exercise rigorously to get these kind of results. I know that."
"You do walk a lot on campus," I said. "That's got to work those buns."
Over ten thousand steps a day, according to her walking app, but Harley still didn't think it accounted for the rock-hard firmness of her bum. She flicked her tee up, briefly showcasing the issue. I almost choked when I noticed she was wearing no panties. Either she was shaven or just barely had any pubic hair. It was too fast to process clearly.
"Jesus, Harley, you really have changed." Never did she flirt, and that seemed like flirting to me.
"Oh, please, like you care," Harley waved off. "I ought to show you my tits. You'd better understand why I spend so much time in the mirror looking at them."
I didn't know quite how to respond, when Harley did just that, lifting her tee above two glorious orbs. They were full and round, yet natural in shape and had two symmetrical and perfectly placed nipples capping them off.
"Isn't this ridiculous? This is the body of a playboy model... a bimbo... not me!"
She was shaven, and by the looks of it, wet. She was just about to drop her tee back down, when I cried, "No! Wait, let me see. I uh... I knew you were getting attractive.. well, uh, hot.. but Harley, damn."
"I know, right?" exclaimed Harley, eyes wide, while still holding her tee up, so I could see all her naked body.
