<human>: Summarize the given text in a few sentences.

So this was a few years back but I definitely still remember it. I was about 16 at the time. My best friend, for privacy let's call her Aly, and I were pretty close. We talked everyday, texted, went out with friends etc. Well all that was about to change. My parents knew hers so if they had to go somewhere and I was bored at home I'd go over to her house since we lived fairly close. One day my parents had a christmas party to attend and I was sitting at home being bored as hell so I decided to give Aly a visit and thought we would watch a movie or something. I got to her house and as usual I was welcomed inside. We decided to go to the basement where there was a projection screen for movies. Coincidentally her parents had something to attend as well so they left about half an hour of me arriving. Now this movie we were watching wasn't exactly clean and so there were sexual references within it. There was this one specific scene which I have to admit turned me on a little. Apparently it effected my friend a little too much and she suddenly came in close. During the heat of the moment I went in as well and it lasted about 5-7 seconds. When we came apart she looked to me and I saw she wanted more. I freaked out and jumped back saying I had to go, almost slipping on the carpet. I went home and thought about what just happened. Maybe I overreacted a little too much, maybe not? She definitely thought so. After that I didn't really go to her house or talk or text her. Thinking back, I still don't know what I should have done but I surely fucked up.
<bot>: Went over to my best friends house (who is a girl), watched a movie with sexual references, kissed her and as things got hot backed off and ran home breaking our friendship.
