I was making out with my boyfriend in the back of his car for the last time before I moved away, so we were getting pretty heavy. We had parked a little way from my home and my parents were expecting me back soon. When time, we drove the short distance to my place and went inside so he could say his farewells to my family. Dad gave him a beer (a fosters in a white can) and he was drinking and talking to my folks when I suddenly realized there was blood on the can. There was in fact blood HANDPRINTS on his can of beer. I freaked and dragged him into the bathroom where I found blood fingerprints on my nack and shoulders too. It turns out I had started my period while we were making out and everything he touched had blood on it! It was so gross. My parents are so cool they have never spoken about it. ....or maybe they didn't even notice!
