Lets find out, shall we?

I blew out hard and came out into the open. A few of the girls did double takes at me. One of them, a blonde in a ponytail, looked like she was about to laugh and then attack.

"Who're you supposed to be," she sneered.

I changed my voice to a female one, or as close to it as I could. It came out as my voice but higher and smoother. Not as bad as I thought. "I'm a substitute for English class. Why are you all still in here?"

The blonde looked like she wanted to say 'you're a guy and I'm offended you think this 'disguise' would work on me', but happened to pronounce it 'the door is blocked and we can't open it'. My plan wasn't working, I knew from this and other girls' mocking or angry looks. Dammit! Weasel would have already had them breaking down the door while two stayed behind to suck him off! I'm not gonna lose to a guy like that! "Then," I said with all the confidence I could. "We must break it down. All of you together should be able to do it, so get to it!"
