My boyfriend and I were at one of his friends pool party.I had started my period the day before and was wearing a tampon.Then someone decided to play chicken.So his friend brad had his girlfriend on his shoulders and i was on my boyfriend mike's.There were about 25 people watching and right before the whistle blows I noticed that i havent changed my tampon and I was bleeding heavily.Then all of a sudden a gush of blood streams down my boyfriewnds back.Everyone saw what happended and were now staring and laughing.I was so embarrased.
