2. Novel:
While I understand that you specifically mentioned "comics," but I will also include some novels/stories with those scenarios that you described because they tend to be more elaborately written.
- "Isle of Laughter" – exquisite F/F tickling. I enjoyed reading. There’s chapter called The Pit where the lee is buried in a box.
- “Ticklish Turnabout 1” – There’s one story there where the male lee is caught by the bed and his feet sticking out (F/M)
- “Agony in Silk” – yet another exquisite novel that involves travel, glamorous women and elements.
