Five generations of builders in the buff are featured in a new raunchy 2013 calendar to aid a cancer hospital.

K & K Building Services, based in Morden Road, Mitcham, have released a 2013 calendar where employees pose in a series of raunchy photographs.

The pictures were taken at various places around Morden, Carshalton and Sutton and will help raise money for the Royal Marsden Hospital.

Darren Mouslou, 40, posed as Mr December and said: ““We came up with the idea after our AGM with Sutton Council. The charity has touched our lives through cancer. It has been a dismal year.

“The wife took that picture. She was up for it, but only because it is for a good cause.”

The builders have produced 150 calendars which they have asked the hospital to sell, as well as clients, friends and family.
