The finish line was coming up quick and Joanne was the first to cross, by just a hair. As she crossed, She looked over at Mark to see his pants bulge out softly around his crotch, until all she could see left of it was a little tint in his shorts that looked oddly like a nipple. "Let's see it." She pushed.
Mark sighed and pulled down his pants, revealing a DD breast situated between his legs. The nipple was erect, and the aureole stood out. "Happy now?" he said with a light, nervous smile. It wasn't the wind making that nipple erect.
"What else can we bet for?" Asked Amanda, looking at Mark's crotch as he pulled the shorts back over his boob.
