Keep Running

You decide to ignore the knot, hoping that the movement of your legs would keep your shorts up. Eventually though, it comes fully undone, sending your shorts down around your knees and causing you to fall to the ground. Courtney gasps in shock, grabbing your arm and asking if you're okay, before erupting into laughter.

"Ohmigod anon where's your underwear!"

you look down in horror at your exposed, flaccid cock. Two inches on a good day, the exercise had caused it to contract into your body, leaving only a head and a small shriveled stump connecting it to your body exposed. You quickly try and kick your feet out so you can pull the shorts back up around you, the movement making your little stump of a cock bob back and forth pathetically, causing Courtney to laugh even harder. She too has fallen to her knees, clutching her sides as she laughs uncontrollably while you desperately try to hide your micropenis. Too late you manage to pull your pants back up, but not after giving your running partner a little show.

"Im so sorry Courtney, I just..."

She cuts you off as she regains control of yourself. "Bro why were you going commando on a run?" She starts laughing again, saying, "I guess you don't have to worry about your meat flopping around ahahaha!"

You're face is bright red now, and you aren't sure what to say. You're certain that any chance you had with her was gone, but surprisingly she gets up and smiles at you.

"It's alright bud, and sorry for laughing. It just caught me off guard is all. Say, this run's busted, you wanna do something really fun?"

Before you can answer she's leading you off the main path through the park onto a side trail, and then again down something which barely seems a trail at all. Eventually you reach a spring, and she gestures to it with a grin.

"I figured we could take a break and go swimming. The water's super clear and surprisingly warm."

Swimming does sound fun, but as you look at the water you remember you don't have a bathing suit. You bring this up to Courtney, but she shrugs it off.

"Me neither dummy, it's called Skinny Dip Spring for a reason. Besides I've already seen it." She playfully says as she pulls off her sports top, revealing two small, perky breasts. Your heart skips a beat as you realize what's about to happen, sending your two incher twitching beneath your underwearless shorts.
