"Garden of Contemplation" by Delta (delta@bc.sympatico.ca). The narrator has raped a young woman. Instead of keeping the event secret or going to the Law, she turns him over to the Society. He is given a short trial and is sentenced to 90 minutes of mandatory Contemplation. That's all - except that if he fails to meet certain conditions or if he makes certain requests additional consequences will follow. Of course, since Contemplation takes place in an open, public area and in a kneeling position, some support is necessary; and all that is available is a set of electronically charged ball bearings that support the buttocks through the anal aperture. You can well imagine....
There have been many stories on a.s.s. that have attempted to give intense portrayals of rape. Some of those stories have been vivid and realistic. I have counseled people who have been raped, and I do NOT believe that rape is fun. However, I understand that it can be pleasurable (and perhaps even harmless) for a man to fantasize about raping a woman or for a woman to fantasize about the "pleasures" that could occur during the act of rape.
The present story takes a different approach. The portrayal of the initial rape is realistic, but not vivid or erotic. The retribution is both realistic and vivid, but not erotic - at least I HOPE you don't get turned on by this sort of activity.
It's difficult to tell you more without ruining the story for you. I strongly recommend this story - but not when you are looking for a turn-on. Use it as part of your Contemplation time.
