A heavster occurs when a female or male is sucking their male partner's special member. The "suckie" then accidentally gags on the penis and commences to vomit all over. The male getting sucked then ends up with a "vomit surprise" all over his beloved cock and balls.
Yo Adrianna didn't fell well yesterday, she was giving me head and she gave me a heavester.
