Getting rid of hickey fast?

I slept over my boyfriend's last night because it was New Year's eve.

We were making out this morning and I playfully bit his neck, now he's worried about getting bitched at at work for it.

It's not really a hickey it's just a red bite mark but he has work in two hours so it won't fade away in time

UPDATE: picking him up in an hour from work, all the things we tried didn't seem to work in time well enough, here's hoping he didn't get in too much trouble
