A slightly OT follow up: (modern) Japanese don't show a lot of interest in anal sex, but anal play is a bigger thing. In the frame caps of RCTD-107, I noticed a clear and blue film applied to the anus which seemed rather curious. Then yesterday I was fapping to another anal-centric vid SVDVD-712 and saw this anal blue film up close. The authority/doctor/pervert applies this medical-looking clear film with a blue circle on to the student's anus.
I was gonna write a post to ask the wisdom of Akiba Online when I made a frame cap of the film being applied:
It so happened the wording is visible on the frame... so let me try to find an answer myself... on the film... pattern matching... 3 hiraganas... not too hard, a kanji for "bug": ぎょう虫 it's
pinworm! TLDR... Oh here it is:
the light-yellowish thread-like adult pinworms are clearly visually detectable, usually during the night when they move near the anus, or on toilet paper. Transparent adhesive tape (e.g. Scotch Tape) applied on the anal area will pick up deposited eggs, and diagnosis can be made by examining the tape with a microscope. This test is most successful if done every morning for several days, because the females do not lay eggs every day, and the number of eggs vary
YEWWWW!
What's even more curious is that the bottom of the film there are blanks to fill in "School Year", "Student Name" etc. So this product isn't just meant for doctors to use in clinics and hospitals, it's manufactured specifically for schools to carry out screening programs for classrooms.
Damn next time I sodomize a Japanese lady, I will have to scotch-tape her asshole for wiggly yellow worms first.
