You know that as a female reader, I had a different feel. AsiaGirl writing the torture has done it just sadistically. My favorite is "Dial T for Tickle Torture..." because it is the kind of sensual tease that I like. Two (2) stories are *blush* hot and arousing! "Spy in the House of Tickling" and "Dial T...". Those two have short term episodes of genital tickle torture. You know that no writer (for a short story at that) will consume and dedicate a plot purely on those spots. The nipple sucking/tickling, which has more emphasis in one story (Tickle Challenge) is honestly a more delicious read.
At times in the story, it is the journey and set-up that makes the hot thing explode. And I love the devices written here.
