April by C. J. Starr
It was a typical spring day at U.C.L.A., C. J. was sitting out on the grass, watching co-eds strolling by, when she meets April. They quickly start up a friendship, and before they know it, a dare arises to measure a handsome passing student.
April was wearing a short white skirt and the way she settled down on the grass had left her naked crotch exposed. I'm nowhere near being a prude, but I did point out to her, "You're showing, April."
"Oh. Damn it!" she exclaimed as she smoothed out her hem to cover herself, "Thanks, C.J."
"No problem, April. I'm not wearing panties either. I love the sense of freedom and it makes me feel sexual. Doctor Spenser loves it when I sit in front of his desk."
"What does he teach?"
