I have watched it before on porn DVDs, but I lost the discs a long time ago. The content is that the male protagonist goes to a adult store to watch porn videos. After watching, three military girls wearing berets break into the store. The leader of the female soldiers later has sex with the owner of the adult store, and the male protagonist has sex with another girl with pigtails.
The screen ratio is 4:3,I think this shouldn't be a work released too late, maybe even after 1995.
Appreciate any help :)
