I (18F) slept with my childhood best friend (18M) on vacation, and neither of our families knows.

I honestly don't even know how to start this because if anyone had told me a year ago that this would happen, I would've laughed in their face. For some background, my best friend, let's call him Jake (18M), and I (18F) have known each other literally our entire lives. Our moms met when they were younger and became best friends, so naturally, Jake and I grew up together. Family dinners, birthdays, holidays, sleepovers, vacations, you name it. If one family was doing something, the other family was usually invited. Our moms joke that we're basically their kids together. They have always said that someday we'd probably end up married, and we'd both immediately gag and tell them to shut up. Jake has always been my person. He's the first person I call when something happens, the person who knows every embarrassing thing about me, and the person I can sit in complete silence with without it being awkward. We've always been close, but recently, something changed. We're currently on vacation with both of our families. It's something we've done almost every October since we were little. We're both 18 now, so our parents have started giving us more freedom instead of treating us like we're still ten years old. A few nights into the trip, Jake and I were sitting together after everyone else had gone to bed. We were talking about relationships since we both recently broke up with our exes, past crushes, and the usual random stuff we talk about at night. Somehow, the conversation turned into whether we'd ever considered dating each other. We laughed at first because, seriously, we've known each other since we were practically babies. But then things got quiet, and I realized neither of us was actually laughing anymore. He admitted he'd thought about it before. I told him I had too. And one thing led to another, and we kissed. I wish I could say we immediately talked about it and figured everything out, but we didn't. We ended up kissing again the next night, and now we've started secretly sleeping together while we're on vacation. I'm not going to get into the intimate details, but the biggest thing is that this isn't just some random vacation fling with a guy I barely know. This is Jake. My BEST FRIEND. The guy who's been in practically every childhood memory I have. And the confusing part? I don't regret it. Being around him feels different now. Every time he looks at me across the dinner table, I have to pretend nothing is happening. When our moms start talking about how cute we were as little kids, I nearly choke on my drink because if they knew what was happening now, they'd probably lose their minds in a good way of course same with our sisters since they want to be related. The best part is that Jake seems just as happy about this as I am. He's been more affectionate clingy and, he keeps finding excuses to be around me, and last night he told me he doesn't want this to be something that only happens on vacation and I don't want that either i want this to be a actual relationship. Edit: Okay everyone this is a real story! But i made it way too long and I wanted it to sound more fluent! So did I use chat gpt for errors and repeats of words cause I use "like" and "because" way too much! So other than that this story is true and I did write it!
