i had a gym class everyday for 5 months in high school, and we all had to wear the same shorts. none of us were really impressed with each other when we saw that we didn't have much underneath our shorts, but one guy always had the biggest bulge in those shorts, and the push from his dick in the front tightened the fabric on the ass, which give everybody a nice view. i remember running laps around the gym, and just staring at his ass the whole time. and then doing jumping jacks i would watch as his bulge went up and down. good high school memories...
