"The Big Time" by Michael K. Smith (mksmith1@swbell.net). The 18-year-old narrator is sunbathing on the patio when she is surprised by her little sister's boyfriend, and so she has a little fun by flirting with him and getting him to ogle her. Then she gives him some sex education - simple things like how to apply sun tan lotion, how to French kiss, how to suck nipples.... The kid takes lessons really well. Then the next day he applies what he has learned to the narrator's younger sister. In addition to being sexy, this story is actually kind of touching.
