Someone gets on next to you

As you are about to make a break for the mens locker room to get your situation under control, you hear someone get onto the treadmill next to you. As you try to act causal looking like you're almost done running, you look over to see who it is.

It's some random girl, but this girl isn't just any old girl, she's stunning, guessing by her looks and what shes wearing you would say she's about 22, she has long blonde hair which has been tied up into two pigtails, she is wearing a grey crop top with black yoga pants, her belly button is pierced and she has a small tattoo running down her side.

You can't help but stare as she is looking down at her iPhone choosing her music but as soon as she moves her hand to put her headphones in you snap back to reality, you have to make a quick decision: do you either get off the treadmill hoping this girl doesn't see your tenting shorts and neither do the women in front of you, or do you stay on the treadmill hoping your hard on will go down enough that it isn't so obvious?
