It was semi planned and semi spontaneous. I was 15 and she was 17. It happened in my parents basement. No one else was home but it was still a scary sort of thing. We didn't use a condom or other contraceptive which was not smart but it turned out okay. I didn't shoot the magic ball of life inside her but damn I sure could have. Wow what a fun experience that was....
I'd like to go back there and try that again.....
