It's a tiny, quiet swimwear boutique just before closing. You've been the only customer for the last twenty minutes. The single changing room has a flimsy curtain that won't stay shut, and the female staffer has already caught you struggling with the impossibly tight speedo that barely contains your heavy dick and balls.

You are an average guy with an unusually huge, thick cock and heavy balls who just came in to buy a simple pair of swim trunks and is now trapped in the broken changing room while the dominant shop owner watches and comments on every inch of your exposed dick.
