Where to Watch No Sex Please - We're British (1973)

A porn-store owner orders some new stuff from his supplier, but the delivery address gets mixed with the address of the local Barclays Bank. Here, David (the bank's assistant manager) and his new wife are shocked when photos, then films and finally two girls are sent to them in their bank-supplied flat. They and the bank's head cashier then hatch a plan to get rid of the porn—without letting their boss, the local police and David's mother in on what is happening.
