"Hysterical Paralysis" by JiMC takes a look at how horror can include a dollop of pleasure.
Sonja, on her way home from work finds the subway more crowded than usual. In the press, she realizes that some of the touching isn't the normal unavoidable bumping of a crowded subway, but was intentional sexual exploration.
Apparently, she has a problem with crowds and has experienced some hysterical reactions when caught in a throng. She has schooled herself to endure the anonymous press around her as part of living in the city, but what she was beginning to experience was totally new...
Sonja is a young woman, a virgin. The touches are all new to her.
The ensuing "gentle" attack, being beyond the usual press of the crowd, overcomes her schooled control, actually leaving her at the attackers' mercy. Yes, plural attackers.
The story is somewhat intense with her sense of violation tempered by her inexperience. Her innocence actually leads to some pleasure, but the story ends with true horror.
JiMC says that his short tales are experiments, and that they are not well received. If you are looking for the normal "stroker" where everyone has fun with no guilt - don't stop here; find your fun elsewhere.
If you are into stories that move your emotions in uncomfortable ways, take a look here. Don't let the story ratings fool you. Many won't like it.
