how to get rid of hickeys FAST?

so me and my boyfriend were just playing around nothing sexual and were super weird together and he sucked on my face cheek because it made a funny noise but it left this hickey! help! I told my parents that it was just an allergic reaction to "blush"  because I do tend to have lots of allergic reactions but it's never really been like this so I am not sure that they are buying it... also I can't use concealer or makeup because I don't have any of my complexion because my moms is a lot darker so it wouldn't work... help!
