Title of a French classic

[joandetarraco]

Pee scenes in 1970s French porn are very rare. I hope this vague description should then be enough.

I remember this scene where (I believe) Dominique Aveline and three girls (one is, I believe, Cathy Stewart) are outside a farm or something like this. Then, the girls pee on the grass.

Does anyone know what film it is? Thanks a lot.
