Back when I had braces I was giving my bf mad head and my braces nicked the tip and he said he barely felt it but be careful. I tasted blood so I looked and sure enough there was a cut on his tip. We go and clean it up and put a band-aid on it. I next give him a hand job and had my eyes closed, next thing I know he's freaking out about blood everywhere. The band-aid had come off and because a lot of blood flows there it was coming out too. Needless to say I didn't give him another blow job till my braces came off
