First, the housekeeping: "April Showers" by Hawkeye was reposted by john_dark@anon.nymserver.com and is said to be part 4 of "Seasons" (c) 1993. The four- or five-year-old copyright may explain why I was unable to find the bigger story. If "April Showers" is an accurate reflection of a larger work, it'd be worth finding. {Celestial note: I am reposting my review of "Hazy Shade of Winter." That gives us two of the four seasons. If anybody has Summer and Autumn, I'd sure like to see them reposted.}

Most efforts at erotica employ a device that positions the players in a situation that allows, even encourages, sexual intimacy. Many of these devices are hackneyed and improbable. A few border on being overworked, but still come through, as does these vignette in a college dorm bathroom.

The protagonist, Sam, meets Julie Brauer, the girlfriend of a dorm mate, as they're both walking to the washroom. Apprehensive of being discovered, Sam still positions himself in an attempt to steal a flash of skin as seen through a large mirror. He reflects a moment on his behavior, recognizing he'd be flustered were he to be confronted with her totally nude, but admits to his voyeuristic compulsion.

At this point, the story takes an unexpected turn, a delightful one, a sexually intense one. And after the culmination, we're left not knowing if this was a one-time thing, never to happen again, or the start of a larger adventure. As such, it's a sweet, erotic slice of life that left me wanting more.
