How I Became Big Sister's Sex Slave

... so we only saw each other in passing. The only thing that took a little getting used to was having to share a bathroom again. Karen wasn't exactly the neatest person and our bathroom was always cluttered with "girl stuff": makeup scattered all over, panties, bras, even lingerie. One day I found a bright red thong lying on the floor in front of the clothes hamper. Absent-mindedly I picked the thong up, intending to toss it into the hamper when I noticed a dark spot in the crotch area. I fingered it and it was still slightly damp. Shit! My sister must have just barely taken these off! Quickly shutting the bathroom door all the way, I raised the thong to my face and sniffed it, inhaling deeply. The rich, musky aroma was unmistakable and my cock stiffened immediately in response to the intoxicating scent. Just then I heard someone coming up the stairs and then Karen saying, "Brian, are you in there? Hurry up, I really gotta pee." I froze, the thong still raised to my face. Damn, what was I thinking, sniffing my own sister's panties and getting turned on by it? What the hell was wrong with me? After a moment or two I managed to reply, " I'll be out in a second."

I never thought of myself as a real pervert (no more so than any other typical teenager with raging hormones anyway) but here I was getting a throbbing hard on at the sight of my sister's panties and the scent of her perfume. I tried to dismiss it as being simple horniness, but still my thoughts lingered on my sister for a long time. Everything changed when mom and dad went away for their annual week's vacation. Since Karen was the oldest, they informed us, they would be leaving her in charge. Needless to say, Karen enjoyed this immensely, and I had to endure a lot of teasing about her being the boss and comments like, "Ok Brian, you better do what I say, remember who's in charge around here." Karen also took advantage of this opportunity to turn our house into party central almost as soon as mom and dad's car left the driveway. She partied hard for two days (and nights) in a row, and there was never any shortage of people (mostly guys, I noticed) who were willing to party with her. Each night ended the same way: My sister, drunk off her ass and already half naked, stumbling upstairs to her bedroom with whichever lucky guy she'd chosen to be her boy toy of the ...
