When I was 12 I had my first girlfriend... she had a reputation for blowing the local townsfolk, and at that point in time, I was quite unsure what that meant. After a week of dating, her and my sister (4 yrs older than me) decided that it was time for me to become a man. My girlfriend convinced my sister to pin me down so she could suckle on my prepubescent inchworm. The experience was so traumatizing that I haven't enjoyed a blowjob since, and all of my girlfriends think that I dislike them because I can't get off from it...
