The time I(m18) lost my virginity to my ex(18f)

I had just gotten back from a trip I took with my family, it was new years eve. At the time me and my ex were only in the talking stage, and i had told her I didn't want a serious relationship. I invited her over for new years eve so we can spend it together. When she gets there it was actually our first time able to hangout together alone, we went to my room and i put on a movie, we started kissing and making out I had to stop almost every 5 minutes because i felt like my dick was about to explode in my pants, eventually we finally get to there she's ready for me I remember sliding her panties down while she was in doggy position, i remember how wet she was it was literally dripping on to my bed, she was so tight I couldn't fit my dick in at first and it was hard for me cus i kept getting closer to explode with every touch. Eventually I paused, used my fingers to spread her lips and shoved it in, I felt her pussy mold and grip my dick i lasted about 2 strokes and immediately came inside her i felt a bit embarrassed so i didn't tell her i was finished so i kept thrusting inside her while still pumping her raw with cum, we ended up fucking for 20 minutes after my first nut, at the point there was no reason to pull out since i already came inside her, since then we started dating and since she was innocent all she wanted to do was please me and let me do so many things to her, i didn't find out she was on birth control til a week later so that definitely eased my mind
