Established in 1993, the prize from Literary Review is given to the author who pens the worst sex scene in a novel.
Huston was only the third woman to win the prize, which was announced by Downton Abbey actress Samantha Bond at last night's ceremony at London's Naval & Military Club.
"I hope this prize will incite thousands of British women to take close-up photos of their lovers' bodies in all states of array and disarray," said Huston's publicist, picking up the award on her behalf.
Infrared is about a photographer who takes infra-red photographs of her lovers during sex.
"The purpose of the prize is to draw attention to the crude, badly written, often perfunctory use of redundant passages of sexual description in the modern novel, and to discourage it," the magazine explained.
"The prize is not intended to cover pornographic or expressly erotic literature."
A passage from the winning novel is as follows:
- "He runs his tongue and lips over my breasts, the back of my neck, my toes, my stomach, the countless treasures between my legs, oh the sheer ecstasy of lips and tongues on genitals, either simultaneously or in alternation, never will I tire of that silvery fluidity, my sex swimming in joy like a fish in water, my self freed of both self and other, the quivering sensation, the carnal pink palpitation that detaches you from all colour and all flesh, making you see only stars, constellations, milky ways, propelling you bodiless and soulless into undulating space where the undulating skies make your non-body undulate."
Last year's winner was David Guterson's Ed King. Previous victors have included John Littell, Iain Hollingshead and the late Norman Mailer.
Musician and author Nick Cave was also given a nod in 2009 for the explicit passages in his second novel The Death Of Bunny Munro.
