Tug!

I decide that since I am already late, I might as well slip into the boy's room for a quick wank. The bell has already rung and the halls are empty of their usual screaming masses. I walk quickly down the hall and turn into the boy's room. I nearly sprint into one of the stalls. I close but do not bother to lock the door, not only am I sure that no one will come in, I am too busy getting my enormous hard-on out of my pants.

As I grab my hard cock, I let out a loud moan. It feels so very good as I start to wank it. I imagine Mrs. Doe's mouth working up and down on my cock. I lean back against the WC, tilt my head back and close my eyes as I increase my pace.

I am working myself into a frenzy and so very close to coming when I hear the stall door open.
