Dear buddies,

Need some help to search a movie.
Sorry, I forgot the movie title but I guess the production year is around 80s. The story is about sex life of two blondes in a car work shop. They are also mechanics.

1st scene: one of the blonde caught her partner is playing dildo. Then they play together having lesbian sex.

others scene: Since they had lesbian sex, they seem like to compete each other by having sex with lot of people including their customers. There are threesome where had ffm & also mmf.

There is a scene where a couple having sex in a car. Another scene is a blonde spy a couple having sex in a room. Suddenly, the girl left and immediately the blonde go into it and have sex with that guy while the guy saying that he is tired. Anyhow, after the blonde give him blowjob, then they start fucking.

The last scene is about the blonde is repairing a car in work shop. A man walk in, then they go to a room and start having sex. While they are doing sex, another man come in and join with them. There are 2 cocks in the blonde's pussy once at the same time. The blonde keep on screaming 'No'. Then, a man fuck her mouth and another continue fuck her pussy.

A very interesting movie. Hope there is somebody can help me find out this movie. Thanks a lot!
