Thankfully no

By some stroke of luck, finally, nobody comes along to make things worse as I wait for my turn, my hands cupped over my crotch as I try to adjust the shorts to cover just a little bit more.

After about fifteen minutes, the girls start to leave their locker rooms dressed in their normal uniforms, quite a few grinning and laughing at me as they pass. Thje coach opens the door to her office, motioning for me to come inside.

The second the door closes behind me, the coach holds out her hand "Shorts off hot shot" she says, grinning as she glances at my crotch, where my bulge betrays the fact that I had started to get hard when I was exposed, and that hadnt completely gone down yet. I already know I dont have a choice here anyway, so I peel off the shorts, handing the to the coach as she openly stares at my cock. I resist the urge to cover, knowing she wont let me get dressed if I do.

The coach laughs lightly as my erection grows from half to full, my body getting turned on both my being seen in the gym and now being openly ogled by the coach

"those poor girls" the coach says "they tried so hard to see that and you just wouldnt let them. Good job getting through the class without showing your cock to all of them though" she says, taking my clothes out of the drawer "tomorrow may be... harder for you"

I hesitate as I take the clothes from her "why is that?" I ask, certain I wont like the answer"

The coach grins wider than ever "oh tomorrow isnt normal gym. Fridays are swimming. And we of course dont have a swim uniform for you. Do you have a speedo at home?"

'oh god help me' I think as I consider what the hell she could be planning "no..."

"Well you better have one. If you dont have a speedo by tomorrow you'll be counted as forgetting yours, and the penalty for forgetting is that you go without it. That applies to every student not just you" She reaches into her desk and pulls out a business card "heres a place in a downtown shopping center. They mostly have womens swimwear but they stock stuff for guys too and they verify the fit for both. Make sure it fits correctly or it wont fly here"

She grins at me as the color drains from my face "thats right. Go get fitted for this by tomorrow or those girls will get the show theyve wanted after all" she laughs, watching me with delight as I get dressed.
