The Itch

The second title by Hammer (John Coleman, Olympia's leading inspiration and top blurb-writer). The Itch, a tale that predates Indecent Proposal by decades, presents Viney, the husband, Martha, his wife, their many desires, and a millionaire who wanders along and offers them seven figures if they act out those desires in interesting ways. But their benefactor is hardly pleased when erotic pursuits occasioned by the pair (like running off to Japan), seem less than novel.
So additional steps are taken to spice things up.
