<human>: Can you provide a brief overview of the text?

So this is my first reddit post, so im not entirely sure of how the formatting. But here it goes..

This happened a few years ago in my sophomore year in high school. It was open house night and my girlfriend and I were both staying to see what was going on at the school that night. We were both really busy setting up for open house, and when we finally got the time to see each other it was like we haven't seen each other in months. So my 16 year-old self was feeling a bit horny at the time, and so was the girlfriend. (My highschool had this science wing where we were hidden from everyone.) Fast forward, we were in one of those hallways just sitting there. One thing led to another, and we started making out in one of the doorways where we were hidden. One thing led to another, and I remembered how she told me she missed it when I fingered her. So that came into mind, and one thing led to another and I ended up in her pants. We were there for quite a while, so eventually I ended up in her shirt as well. This went on for about 40 minutes.. at the school.

Now this is where I fucked up. I heard footsteps of some sort, but I didn't stop, and she didn't stop me. I knew someone was coming, but I never thought they'd see us. Right when she started twitching from her orgasm, I hear an *ahem* cough, and I knew I was fucked. We both turned around slowly to see the face of a teacher. (Who I just found out now will be my chemistry teacher.) He threatened to call our parents and told us to leave immediately. Good thing he didn't ask for our names.
<bot>: got horny after hours at school with gf, fingered her in hallway, got caught by teacher who I now have to spend a whole semester with.
