Good thing it was me and not my sister.
Back when I was 16 and got my license, I borrowed dad's car for a date one Friday evening. The next day, dad got home from work and he cornered me saying 'I need to ask you something'. He took me outside where we'd be alone and he said 'I found the stains on the door panel of my car. Who's the girl'? I told him that I was out with a girl named Carol. Then I asked him, 'what stains'? My dad said 'the cum stains'.
I was in shock at this. I had no idea something like this had happened last night. I just stood there looking at him. Then he asked 'feel good'? I still just stood there. He then said 'next time, make sure you take a napkin or something'.
I got to thinking what it would had been like if it had been my sister instead of me. He went back in the house and I went to the car to see the stains. Sure enough, there was these stains in the cloth material. And, sure enough, Carol and I did have a little fun last night with Carol giving me a hand job. It was dark and I didn't know the cum shot out that much. It was my first from a girl and I knew it sure felt good and happened fast.
Next date with Carol, I did as my dad asked and took some tissues with me. And, we did sure need them that night. Carol and I got each other off that second date. My first seeing and touching a girl there. First but certainly not my last.
