Maybe... you do have a perfect ready-made excuse after all.

Considering the forbidden zone that lay just on the other side of the girl's room door, I was treated to a quick flash of the scene I'd witnessed earlier in the nurse's office, the thrill of seeing something you weren't supposed to. That, and the resulting pulse of pain in my too-tight pants crotch, gave me a momentary surge of bravery, and before I knew it I was testing the door with my outstretched hand.

It wasn't locked, and offered little resistance as it swung open at my touch. And then I was inside.

Was I here alone? I stood silently in the bathroom entryway, listening carefully to see if any girls occupied any of the interior stalls, and taking in the atmosphere. It was familiar yet alien, the mirror reverse of the locked boy's room, and possessing a vaguely floral aroma, made all the more intoxicating by its faintness. I felt like I was defiling something simply by breathing that scent in.

Wait... what was I doing here again?

Oh right, my pants. Stepping further into the room, past where the urinals would be if this were a boy's room, I unbuckled the belt, putting the hook through another hole in the leather two notches down from where it had started. But I was aroused now, and even that extra room wasn't enough for my painful erection. I unbuckled it again, and moaned softly at the relief.

I took the belt by the buckle end and pulled, the leather strip sliding out of my belt loops, depositing it in a pocket on the side of my backpack.

As I twisted back around, it sent more shockwaves of pain radiating from my lap, worse than before, causing me to nearly buckle at the knees. What was this? Without thinking about it any further, you clawed at the button fastening your pants shut at the top of the fly, tearing it loose and sending the brass disc clattering across the tile floor. The unusual pressures affecting that area caused the zipper to unzip itself, as if pulled by a ghostly hand... and suddenly you were out of your pants, your red cock seemingly taking in the atmosphere as you had before.

"Hello?" came a quiet voice from the stall nearest the corner your button had tumbled away to. Shit. Had you been so consumed by the scent of the place that you failed to notice you weren't alone?
