Melvin, Son of Alvin (1984) – John Eastway.

'If things get rough, you may have to use sex!!!!!'

Legendary Aussie cocksman Alvin Purple's angsty teenage son Melvin (Gerry Sont) has an equally magnetic effect on women, but he is a timid, painfully shy virgin, aggressively pursued by hordes of libidinous lovelies, he is unable, or unwilling to consummate, Melvin hopes his infamously priapic father can remedy his mounting frustrations! While unapologetically crude, frequently salacious, and triumphantly silly, the bawdy comedy Melvin, Son of Melvin proved to be an amiable enough coming of age romp, with the onus on 'coming'. Will poor Melvin finally pop his cherry with his gorgeous Greek paramour? (Lenita Psillakis) Will his sexually depleted father Alvin (Graeham Blundell) get his monolithic Mojo back, and will the frisky Purple People cult orgasmically reach their Alvin-obsessed, nookie-fied Nirvana? All this, and a lurid preponderance of gratuitously jiggly T&A shall be naughtily exposed in Eastway's zesty 80s time-capsule of crudely slap n' tickled Aussie humour. As an additional bonus for Dr. Who fans, the blissfully bouncy cast includes the delicious Katy Manning, one of Jon Pertwee's more memorably luscious companions.
