It's after school and I am waiting for my friends in the gym. I play on my phone. I don't even notice you under the bleachers, looking up my skirt. Girls aren't supposed to wear thongs to school! Seeing my cute, peachy ass drives you crazy. You start furiously stroking as I mindlessly scroll on my phone. My skirt barely covers my ass. My blue, satin panties are so tight. You want to reach up and touch me but don't want to get my attention. A few times you almost get caught! I hear something! But it's probably just other students in the gym. I continue to stand right over you, oblivious to your horny thoughts.
