I saw this in the early to mid-90s, on VHS. It was dubbed into English but I think the original was German.
Two girls arrive at a beach in a jeep and are promptly met by some guys. The curly brunette goes off with two of them and the blonde stays with another. The girls end up working as maids/sex slaves at a nearby hotel, the curly brunette seeming to get most of the work. Their boss was an older woman, in her 30s. There was an orgy scene at the end where the brunette gets fucked on a table (may have been a pool table). I can't remember any other details but I'd like to take a trip down memory lane if anyone can help!
Thanks.
