Jake and Danielle

Hi, my name’s Jake. I’m 17, I have short cropped dirty blonde hair, blue eyes, glasses, and a relatively clear complexion. I’m 5’8”, 145lbs., and I would say my body is fairly well toned. I’m no muscle-kid, but I’m pretty average.
Speaking of average, my cock is just over 6 inches long, and 5 around. I always hear conflicting ideas about what makes a good cock: length, girth, or sexual ability, but I don’t pay much attention to them. Why should I, when the one girl in my life who really matters to me likes it just the way it is?
I speaking about my 15 year old sister, Danielle.
We have sex whenever possible, whether it’s in my room, hers, my parent’s, or just about anywhere else in the house, but we always wait until we’re alone. Thankfully, both our parents have full time jobs, so we have plenty of privacy.
Danielle is about 5’5”, 120lbs., with shoulder-length pitch black hair, small, firm tits, a nice bubble ass, and perfect smooth skin. She’s not particularly tanned, but when she’s naked I can see where her bikini has been.
I go to a regular high school, but she’s enrolled at a private school. Because of this, she always comes home wearing her uniform. White blouse, green and black pleated skirt, thigh-high socks, and little black shoes. Whenever she walks in the door wearing that thing I get an instant erection. It’s just magnificent.
I get home before she does, as my school is closer, so I always have time to wash up before she arrives. The story I’m going to tell you takes place on just such a day.

The front door opened and I looked up from the magazine I was reading. It was one of my sex mags, so I already had quite an erection. She bounced into the house and shut the door behind her.
“Hey cutie,” I said nonchalantly. I closed the mag and set it on the table.
“Hi Jake,” she replied happily. Her hair was wind-blown and her cheeks were rosy red. It was early November, and the cold weather had already set in.
“Good day at school?”
“No. Is it ever a good day at that fuckin’ school?” Sometimes I get the feeling that she cusses more than I do.
“Fuck no,” I replied, not to be outdone. “Let me help you with your coat.”
Whenever I say that to her, she knows exactly what’s coming. She grinned and leaned her back against the door. I stood up and strode over to her, trying to hide my erection as best I could. Not that it really mattered to her.
“I can’t very well take your coat if you’re leaning back like that, now can I?” I asked when I reached her.
She looked down at the tent in my pants and laughed. “Anxious, Jake? Or were you preparing again?”
“Little of both.” I almost blushed.
“Who’s prettier, me or those whores in your mags?”
“You. You’re my little whore. Those other girls just wish they were you.”
She bit her nail seductively. “You know, I saw you leering at Sandy today. In the hall, when you were at your locker.”
“Leering’s a bitch of a word, Danny. Try ‘casually observing’.” My erection began to drop. Was she actually pissed about it?
“I don’t care what you call it.
