My sister Katie had always been the cuter, privileged sibling that got her way. Even though we were twins and went to the same junior college, she had a car, a boyfriend, was in several clubs at school, and everyone liked her. She was pretty and well known.
On the other hand, I was having trouble adapting to college. I had some guy friends that went to college with me after high school, and it was OK hanging out with them. But I really wanted to start dating college girls. It was hard because all the girls wanted to date older guys and I was at the bottom of the heap.
Katie never had any problem finding boyfriends. She went out with lots of guys. I won't say she was a slut because she definitely had her standards, and a nice image to maintain. On the other hand, she never spent a Saturday night alone.
It was kind of hard having Katie as a sister, because she was hot. And by hot I mean sexy, cute, and sensual. She dressed nicely with just enough style to be classy, but with clothes that always seemed to enhance her "assets". So, I have to admit I used to lay in bed and think about her, and even jacked off a few times. Yeah, she was my sister, but she was also the only girl I had ever seen mostly naked, and she was, as I said, Hot.
So it all started one evening when I asked Katie if she knew this girl Amy. Amy was in school like me but was a cheerleader so I thought they might know each other (Katie was also a cheerleader). She said yeah she knew Amy, and then looked at me like, what are you thinking?
"What?" I said.
"Amy is outta your league, Matt." Katie was kinda blunt. In fact, I think she liked poking me and seeing me wriggle.
"Why? I mean, she is my age, and is pretty good looking but so am I."
"Amy is a slut, Matt. She sleeps with all the jocks. But she prefers older guys. In fact, I happen to know she is fucking Jake Madigan right now."
Katie got up from her chair and began changing into her cheer outfit right in front of me. Thinking about Amy, the short brunette cutie sleeping with that hulking bastard Jake made me horny. Watching Katie take her top off made me hornier (she still had her bra on). When she slipped off her pants in front of me, my hard on became really noticeable through my jeans and I could help but reach down and touch myself. Her legs were so long and smooth, and muscular. Her ass was pretty tight too.
When she leaned over to put on her skirt, Katie saw me touching myself and spun around, straightening the short uniform and looking at me accusingly. "Are you leering me, Matt? You some sort of perv? Huh?"
I blushed, deeply, because I had been caught stroking my erection through my pants while looking at my sis. I knew this wasn't exactly OK, but heck, she had been strutting her stuff right in front of me!
