I have a sister who's a year younger than me. We have a few tastes in common, and one of those is horror movies; not the crap that passes itself off as horror today, but real horror movies, like from the 70s and 80s. If you saw my sister, you'd probably know right away what kind of movies she likes. I've actually told her a few times she looks like that Pretty Reckless chick. She then tells me I look like Chekov from the new Star Trek. It's a thing with us.

Anyway, one of our rituals is, every Friday night, after Mom and Dad have gone to bed, we go down to the den in the basement, turn off the lights, break out the junk food, and put on a horror movie marathon. And they can go on pretty long; there's no windows down there, and more than a few times, we've come up to go to bed, and been hit with the sun.

A couple of months ago, though, something weird happened. Now, my sister and I are mostly horror movie-proof, but there's occasionally one that can make one of us jump. So, we were watching this one, and suddenly my sister lets out a high-pitched shriek that I swear could've been heard two towns over, and jumps on me, throwing her arms around me. As she's recovering from the scare, she suddenly realizes she has her arms around me. She looks at me, and we spend a very awkward minute staring at each other, then we all of a sudden just start making out with each other. It was like a movie; one second, we're staring at each other awkwardly, the next, our lips are pressed together. Only, this was my sister. Weird. This went on for about a minute, until we suddenly realized what we were doing, and pulled away from each other. We both went to bed early that night.

Over the next week, it was extremely awkward for us to even be in the same room together. That Friday, we confronted each other about what happened.

"I really like watching movies with you, but we can't let that happen again."

"I totally agree, we just...we have to be careful."

That night, we tried doing the marathon again, but it was...cold. Something had been sucked out of the experience. Several times, I found myself staring at my sister, and feeling this urge to go sit with her, like everything was normal. Then, at some point, I looked over at her, and found her looking back at me, wearing the same longing expression I likely also had on my face. We stared at each other for a long time, until finally she came over, and sat next to me, then gave me a long passionate kiss.

"You know, I was just thinking, we both love each other so much, really, why is it so wrong for us to express that love in a physical manner. I mean, the only thing that would be so bad is if you knocked me up, you know??"

"Yeah, that would be bad."

"But, I know you're smart enough not to let that happen, and I know I am, too. So, why can't we just express our love the way we want to??"

"I guess you're right."

She cracked a smile, and kissed me again; this time we both held it for a long time. We both spent most of that night making out. Over the weeks since then, our Friday night make-out sessions have been getting steadily more hot and heavy, to the point where, last week, she let me feel her up, under her bra. It was surreal, but I enjoyed the hell out of it. I think we both know, at this point, it's not long before we go all the way. It's weird, but my sister is absolutely right; with the depth of our love for each other, why is it so wrong if we decide to take it to that point. I just know our first time is going to be special.
