I first read this story 5+ years ago, but I can't remember the name and can't find it now. The main character had just graduated HS and went camping with several male classmates. She had been raised to believe that just kissing would get her pregnant. The guys trick her into thinking that if they don't orgasm multiple times a day that they will be in severe pain so she helps them out. Starts out as 1 on 1, leads to group, anal and bareback ending in pregnancy. I think the girls name began with J, but I'm not sure. Any ideas??
