"Silent Intruder" by Annette (an545004@anon.penet.fi). The young girl is feeling dejected on the eve of her sixteenth birthday. She has quarreled with her boyfriend, and the family is throwing a small party to try to cheer her up. She's in the pits of depression. But wait! Her brother comes home from the air force with a friend who will stay overnight. He's a hunk, and her brother arranges for him to slip into her room through the window for a night of ecstatic bliss.

The title has three meanings. The young man is a pilot of a stealth aircraft - a Silent Intruder. He enters her room noiselessly; and even though their sex is wildly enjoyable, they must be silent, since the parents' room is right next door. The final meaning you'll have to guess; but it has to do with those silent little critters that squirt forth from the penis during intercourse - and supply a good reason to take precautions against pregnancy before doing something like this.

In the United States air force pilots who do things like this become responsible for child support and are subject to presecution for statutory rape; and sixteen-year-old girls who get pregnant have about a 90% chance of dropping out of school and living their life in miserable poverty on public welfare. However, this story shows obvious signs of British authorship, and I think the Brits would simply send both the pilot and the girl to a penal colony in Australia, where they would become pillars of the community in Alice Springs or some such place. But it was a really good fantasy!

Practicality aside, this is a good story. The author does an exceptional job of making the need for silence seem really sexy.
