well if you blow some air into your condom put it on it makes ur penni look bigger.

if you blow chunks into your condom and put it on, its basically the same as ribbed pleasure

You should bust out the Peter Grifon line, walk upto your parents look them dead in their faces and say "Hey Mom & Dad either of you guys got a condom?", "Oh nevermind, I'll just use this milkyway wrapper!", pull it out of your pocket say nothing else and just turn and walk away. Exit room, and drop over laughing as your parents go into shock and complete disbelieve.
