I arrived at the station expecting to see mom or dad picking me up, but instead, I saw my exuberant sister jumping and waving at the platform. She wasn't too hard to spot; that blonde hair blowing in the wind really stood out in a crowd.
"Callie!" I shouted and waved back at her.
She came running. Jumped up at me and made me lift her off the ground.
"Yaay! My big bro's home!" she practically squealed.
"All right, all right, don't overdo it, I'm just here for the weekend..."
I put her down and took in the sight of her; I hadn't seen any of my family members in almost six months. She looked like she'd dressed up a bit, wearing a nice yellow summer dress as well as some pretty earrings. She had also done a really good job with her makeup. From what I remembered, it wasn't that long ago she was the typical clumsy teen who either used too much or not enough. At this point, though, I had to admit she looked good - almost like a proper adult. Well, technically, she was one at this point. She was only two years younger than me, about to turn nineteen this weekend. That was part of the reason I was here; because I was unable to come home for her eighteenth birthday, she was determined to get the whole family together for her nineteenth.
We got to the car and she practically jumped in the driver's seat, as if afraid that I was going to usurp her driving privileges. I remembered the feeling from the time when I got
my
license; any opportunity to get behind the wheel was happily taken, and whenever someone else could feasibly be a competitor for that seat, you had to be quick. I didn't put up a fight, though; it had been a long train ride and I was happy to get in the passenger seat.
"So... how's college?" she asked as she drove us out of the station area.
"Good. Great, actually. It's a really nice campus, we've got some really good professors... there's this one guy running our history class who's got us laughing so hard when he..."
"Any girls?"
"... er.... what?"
"Any
girls
?!"
"Uh... yeah, I think you'll find that girls are allowed to go to college..."
"No, I mean: are you
seeing
any girls?"
"Yes, all the time. I'm not blind."
"Duuuh..."
She rolled her eyes at me, but dropped the subject for the moment. I wasn't really seeing anybody right now, but I wasn't going to tell her that. She was always trying to dig into my love life, like a journalist trying to get the latest scoop on a celebrity. I guessed she was just being nosy.
We drove home, making small talk. Apparently, mom and dad had taken up new hobbies, we'd had new neighbors move in next door to the old family home and Callie had started looking at colleges. Nothing to write home about, really. As we pulled into the driveway, mom was already waving us inside, having spotted us coming up the road.
"Come on, you two, dinner's almost ready!"
Good timing, I thought and hopped out, grabbed my stuff from the trunk and followed sis inside. Being a typical heterosexual male, my eyes strafed down from her neck to her feet, just checking out her shape real quick before heading in. She really did look good in that dress. And she must have been working out a bit more recently; I was sure that her waist seemed a bit slimmer than the last time I saw her. But okay, that's enough looking at my sister's ass, I told my permanently hormonal brain.
Having put my bags away in the spare room, I went straight to the bathroom to wash up before dinner. Callie was already using the sink in there and I ended up waiting behind her for a minute. She washed her hands thoroughly... and then she started checking her makeup in the mirror, touching up her cheeks with a brush.
Eventually, I just lost my patience and stepped up behind her, reaching around her petite frame and turning the faucet.
"Hey!" she complained, smiling in that sibling rivalry kind of way she does sometimes; kind of offended and mad, but not really.
"You were taking too long." I replied dryly.
"Yeah, and you - with your orangutan arms - can reach around me even from the other room.
She leaned forwards and turned her attention back to the mirror while I started washing my hands.
"So what are you doing back there? Trying to take me from behind or something?"
She smiled cheekily and started pushing her butt back towards me. I felt her rubbing against me, gently wiggling back and forth.
"Hey, stop messing around, I'm just trying to wash up here."
"Oh, I bet. "
I rolled my eyes as she kept teasing me with her wiggling. She returned to focusing on fixing her mascara, but also kept moving her ass from side to side, rubbing against me.
It got me hard. Yes, she was my sister, but doggy style is my favorite sexual position. There's just something about taking the girl roughly from behind and seeing her round butt cheeks bounce into me that really turns me on. A round ass curving in towards a narrow waist... that shape is just amazing to look at from behind. Callie had a perfect example of that womanly shape. By the time I had finished and stepped away from the sink to dry my hands, there was a distinct bulge in my pants.
I faced the wall to avoid her seeing it. And to avoid staring at her. She was still bent over the sink, getting her face really close to the mirror for her final makeup touches.
"Stop staring at my ass, you perv." I heard her say from behind me.
"What? I have my back turned, you idiot."
"Well, you
were
staring."
"How the heck would you know?"
"Because my ass is amazing and every guy stares at it all the time."
"Well, I'm not every guy..."
"No, but you have a dick and when a girl with a hot ass is around, it does the thinking for you."
"Right..."
I was getting a bit annoyed and decided to head out to dinner.
"Don't go yet." Callie suddenly interrupted.
"What? Why?"
"I have a question about college."
"So ask it later, I'm hungry."
