Campus Tramp by Andrew Shaw

Linda starts to get a reputation as the campus tramp, and guys ask her out only with sex on their minds. Linda doesn’t care what people think of her. Her roommate, Rachel, is quite concerned, and one drunken night, when Rachel gives Linda a massage, the two girls go at it. Linda is shocked by what she has done, and her roommate confesses that she’s been a lesbian since she was fourteen.
