Sometimes there is a fourth scene in there with sharing, there is also the occasional scene where a partner or boyfriend is to watch (and often threatened - blackmailing the girl into having sex with someone).
Almost every movie has one scene in which the agent is fucked while wearing a catsuit that is unzipped/torn to expose breasts, pussy, and ass - usually there is a doggy-style part with this outfit. All scenes are included in this pack, I am afraid there was a glitch with the previous one and a couple got lost in the ether.
This is the second half of a collection of my other favorite type of JAV porn: female investigators get trapped by whatever crime ring they are investigating (usually drugs or sex trafficking as near as I can tell), and then fucked.
