B&D outside of the dungeon is a nice change.
Cleo and Nicole are sunbathing in bikinis on the beach. They've rented surfboards for the day, and when Mr. Biggs comes by, he busts them for some expensive damage he claims they inflicted on his beloved boards. The girls can't pay, so he takes it out in trade - bondage trade, that is. The girls won't let him have sex with them, but anything else goes.
Cleo gets gagged and tied to the futon; perky blonde Nicole pouts when she's bound to a chair in the other room. Mr. Biggs makes sure to strip the girls of their bikinis in subsequent ties, and he even feels the girls up a little, once in a while. For the final tie, he binds them both naked to the front room's futon and leaves them to struggle alone. Agile little Nicole manages to free them both - at which point the two girls awaken on the beach and realize that it was all a dream.
The major technical flaw in this movie is the lighting. Every indoor shot from below is lost in shadow, while the outdoor scenes manage to make sunny southern California look overcast. The knotwork is nothing to write home about either - purely utilitarian. At least the girls are cute.
