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?

If you were a girl with a huge jizz stain on your sheets then maybe you'd have a reason she would care.
