I have a giant jizz stain on my bed sheets

Now, how do I get rid of that stain before my mom cleans my sheets and discovers it?
It's focking huge, no joke. I am impressed that I was able to do that, as in all my years I had never left anything that I could see.

So yeah, ideas?

First, I am 18. Just graduated High School. I've got a little bit before I'm gone though. In the mean time...

Orange juice? Yeah I guess I could do that. But man, I hate the idea of doing that. Also, not sure how my mom will buy the story that I was drinking a glass of orange juice on my bed, lifted the top sheet for some reason and then accidentally spilled it on my bed.

Also, I am fairly confident I am not licking my own semen.
