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?

Why? I dunno. I've thought about it. My mom is pretty liberal (How liberal? She was born and raised in Los Angeles for 30 years...), so she might be ok? Meh.


Anyway, I spent 10 minutes spitting and rubbing and I'm not sure if it had any effect. I think it did, but I can't be sure until it dries.
