Stroke is another name for erotic fiction.
Stroke can take as many forms as there are sexual desires. From languid, pastelled foreplay to graphic, sweaty hardcore to latexed and leathered BDSM, there is a stroke for everyone.
The stroke writer can build scene upon taut and luscious scene, painting layers of skin and sensation and emotion before the lip-smacking, finger-licking climax crashes. On the other side of the bed, stroke flash fiction drops the reader in medias res, on the furious tongue, with the final blind thrusts, deep in the barrel of the orgasmic wave.
Successful stroke encourages the reader to join the characters, to enjoy a invigorating swim in the ocean of masturbation, splashing word for word to the last line until spent on the beach. Hence the name. In fact, the highest praise you can give to a stroke writer is "I came to your story."
