Getting gf to give head?

My girlfriend doesn't like sucking mah dick. I like it. I go down on her lot's, as in every second day. She has given me a total of 5 minutes dick+mouthage in almost 4 months.

WTF?

Should I just cum on her in her sleep?

dude the only real thing to do is kill her. all her friends, and then yourself at school tomorrow. It's the only way.
