Jennifer

It's sports week at school and today is the 5 K jog. The course is separated by class and gender. The youngest girls go first, then boys of the same class, following that pattern until everyone has gone.

It's now the Senior girls group turn. Jennifer, a tomboy type girl you've known for a while decided to stay with you instead of trying to win. "The prize there trying to give away is kinda lame anyway." She reasoned.

Since the start, you noticed how distracted Jennifer was whenever a female classmate passed us. You eventually noticed something bulging in her track shorts. Eventually, Jennifer said "I need a breather." Before taking a corner to hide. Follow your friend, you found her leaning against a wall, cock fully erect, twitching and straining against her shorts.
