I am 15 years old and she is 14. There was a party at my house yesterday evening and that's when it happened. It was totally unexpected because we were not even very good friends. We were just normal friends and barely talked. I have known her for a little over a year now.
At the party, it is a usual trend for all the adults to sit in the living room downstairs and the kids in my room upstairs. Of course I was engaged in conversation with my friends. After dinner, slowly-slowly all the families started leaving. In the end there were only about 5-6 families left. We were the only kids left and were alone in my room.
So, we talked for about 10 mins. on various topics like movies, songs and then suddenly both of us stopped. We looked at each other for about 2 mins. It was like we had a mutual instinct of it and without saying a word, started moving our faces closer. I pressed my lips softly against hers. Then we looked at each other and smiled. Then I kissed her softly again and then after a pause again for the third time. Then we stood ad I held her by the waist and started kissing her again but harder this time. I did this twice and then we started using tongue as well.I moved my tongue into her mouth and explored it followed by her doing the same. Then we kissed once more passionately (in a sort of desperate/dirty way). Then I pushed her against the wall. With her facing me I pressed her body against the wall with mine, and held her cheeks and neck with my hand and kissed her again very passionately. Then she walked away and lied down on the bed and called me. I got on top of her and gave her a long kiss.(Just a kiss, nothing more)
Then we sat up and were silent for about five minutes and then went on to talk for about 20 more mins before her parents called on her from downstairs. She quickly kissed me on cheek and started going away,before I held her hand and pulled her close to me and kissed her again as a gesture for saying goodnight. She smiled at me and went.
This was totally unexpected as we were not great friends either. I am yet to meet her again. i'll meet her tomorrow at school bus. Why did this happen and what should I do? I can't stop thinking of her. Please help me.
