I saw them in the 80's in France on the Canal+ pay channel.Here goes:
One scene has a guy giving his wife oral sex in their bedroom and the doorbell rings, it's a short haired blonde in a white coat (I think), they sit on the sofa and she gives him oral sex a bit as he looks out for the wife. He meets her in a park the next day and screws her against a tree. The last scene in the movie is the guy and the wife all taking part in the big orgy. The wife was a bitchy looking brunette!
The second one: basically these people break in to a house and just have (consensual) sex with the homeowners. There is at least one hetero scene in a big bath tub and then one between two women where they "grind" their crotches together in the hallway at the top of the stairs as the cops are arriving... or something.
Thanks!
