The Heath Is Green (1972)

Norbert inherited a building in the lonesome German heath and now takes two days off to combine an inspection of his new property with a vacation in the relaxing landscape. Two run-down friends join him, and they swear: No alcohol, no nicotine - no women! The house turns out to be an empty barn but - surprise, surprise - there are the pretty maids Ursula and Anna who are willing to comfort them. So the vacation won't be as relaxing and abstinent as planned, but much more fun.
