I hated when my parents made me go into the south of the city with my little brother.
The only reason I ever had to go to that neighborhood in the first pace was to visit our grandfather, who lived in an assisted living facility now. He could still do fairly well on his own, and didn't have a full-time nurse, but his mobility was a bit limited and some of the medications he was on affected his personality. They lowered his inhibitions and among other things, that made him curse a lot. Sometimes he even started taking off his clothes, saying he was too hot, but I would leave the room at that point.
It was always awkward to be around him now when I remembered him being a stiff, formal person when I was little. Mom and Dad said to act like I didn't notice his strange behavior, but it was difficult when he would ask me about grad school and casually call me a fat cunt in the same sentence.
It was still easier to be around Grandfather than my little brother, though. Jules was just over a year younger than me and had always been clingy. When we were young it had just been annoying. It wasn't until after I hit puberty that it really got bad.
Jules had always been tall for his age, and I had always been short. When I hit puberty I was already a chubby kid, and my breasts grew faster than I knew what to do with. For a while all my shirts were tight and I didn't realize how low-cut even fairly modest necklines looked on me. Not until I realized that the reason Jules would always stand so close to me was to look down my shirt.
"Celia, how many stops away are we now?" he asked, stirring me from my thoughts. We were on the train to see Grandfather now. Even though it was the middle of the day, it was the weekend, which meant it had been too crowded to sit down when we'd boarded.
I shrugged, my t-shirt riding up on my stomach a little. I tried to reach forward to tug it down, but I couldn't get the front of the hem without my arm rubbing against Jules' stomach too. "I'm not sure, but we're at least fifteen minutes out from the right stop."
"Mmm," Jules said, frowning. He scratched his chin, happening to brush his arm against my breast in the process. "You remembered to bring the box, right?"
I sighed. "Yes, I got it from the counter." At least my brother was normal in this respect - all my friends said their brothers asked to put things in their purses when they went out. Jules had bought and wrapped something for Grandfather but wanted me to carry it, since I was the one with the bag.
He grinned. "Oh, good. I think he's really going to like it." The train slowed down, rocking me forward slightly. Jules' eyes slid over me and he wet his lips.
I shifted uncomfortably. It was summer, which meant it was harder to cover up. I was old enough now that it wasn't strange to wear low-cut things anymore, even with my breasts as large as they were, but Jules had never stopped his habit of paying too much attention to my body, so I tried to dress modestly around him. It didn't always work - especially when our parents weren't around.
Right now the train was so crowded that we were pressed up against the wall at the end of the car. I had on a light, semi-sheer scarf to cover up my neck and the tops of my breasts. I had my back to the wall and Jules was facing me, his eyes focused straight down.
When we were still young enough to play doctor, Jules used to eagerly insist on 'examining' me, and that was the look he had on his face right then. My cheeks turned pink and I turned my head to look out the window of the train over the tops of the heads of everyone lucky enough to have a seat.
It wasn't that I was ashamed of my body. I was still chubby, or maybe even just fat, with thick thighs, a big belly, and round, generous breasts. My face was round and my arms big too. I used to be more self-conscious, especially of my fat ass, but I had worked hard to gain enough self-confidence not to be ashamed of my size. It was just hard to be around my brother. He tended to look at me like I was a piece of meat.
Our parents didn't see it. No matter how many times I'd tried to explain it, they didn't think Jules was anything but normally curious about a woman's body. Eventually they'd convinced me that he was just too shy to have experience of his own and because of that he'd been too interested in my development. He'd never dated anyone, despite being fairly good-looking: tall, muscled from jogging every morning, tanned, with short blond hair and bright blue eyes.
Now that we were both old enough to be in college, me in grad school and him in undergrad, he had cooled off to mostly staring. We definitely didn't play doctor anymore. If I stayed at our parents' house at the same time as him, sometimes a pair of my underwear would go missing from the laundry, though. And once a few months ago I had caught him looking at me in the shower.
But the only times he touched me anymore was to squeeze against me on crowded trains. Which my parents said couldn't be helped, and so it was no big deal for us to visit Grandfather together at the same time.
One of the men sitting down caught my eye and smiled slowly. My blush deepened and I tried to lose his eyes, looking higher up through the window, but his eyes followed me. He looked like a typical businessman, but I rode public transit enough to know not to trust any strange man on a train or bus. He stretched casually and his foot brushed mine. I frowned and looked away from him, focusing on the logo on my brother's t-shirt instead.
The train came to a complete stop and the momentum forced me to rock forward again. My breasts pressed against Jules' chest for a brief moment before I could push back.
Except Jules leaned forward at the same time, subtly rubbing the inside of his arm against the curve of my breast. Both his hands were in his pockets, and I'm sure he just looked like he was crowding me a little. I bit the inside of my lip and tried not to squirm. I'd learned a long time ago that fidgeting, squirming, or trying to wriggle away from him just made him more aggressive with his touching.
He wasn't ashamed to touch me like this when no one we knew was around. It didn't help that we didn't look alike. Aside from just having different builds, our coloring was much different, too. I didn't tan as well as him and my hair was a very dark brown, as were my eyes. No one ever thought we were related. I know Jules knew it, and I'm sure that's why he felt very comfortable inching even closer to me when more people pressed onto the train.
My ass pressed flat against the wall behind me and I felt my breasts flattening against my brother's chest. It was so hard not to squirm. Even with the air conditioning blasting, I felt hot all over. There was definitely sweat starting to drip between my shoulder blades.
The doors beeped as they closed. A big group of baseball fans had just boarded and their conversation drowned out all the other talking around us. I cringed as Jules leaned down and put his mouth next to my ear. I glanced out the window again so I wouldn't have to stare right at his throat. His scent flooded my nose and my blush started to creep down past my neck. Jules smelled wholly masculine, like pine from his deodorant, and a little like sweat, but not entirely unpleasant - if he'd been anyone but my little brother.
"Are you excited to see Grandfather?" he whispered in my ear. "I can feel your nipples poking through your shirt. Or are you just happy to be with me?"
"I just want to get off this train soon," I said, flatly. "It's too cold in here."
Jules smiled and slowly pulled one hand from his pocket. He curled it around my hip and slid it backwards, casually grabbing a handful of my ass and squeezing. I couldn't help but squirm even though it just made my breasts roll against him. I hated when my brother touched me, let alone was brazen enough to grope me in public, on a train, where anyone could see us.
The businessman was definitely watching, or at least not ignoring us. He probably thought we were girlfriend and boyfriend. Well, anyone would. No one would ever look at us and think that they were seeing a brother squeeze his older sister's ass or grind his hips into his sister's stomach.
Jules didn't let go of me for the rest of the train ride. He let the train rock us against each other and I felt his cock stiffening in his jeans, pressing against my stomach. He managed to move his hand over on my ass so he could rub two fingers over my ass crack, pressing his fingers into my flesh through the fabric of my skirt.
"I wish you wouldn't do this," I said at one stop, when the noise of some people pushing through the crowd to get off the train covered up my words from anyone who might hear me.
