Christmas Box 

Outside it’s snowing, but inside they’re heating up the night. Natasha is expecting to spend Christmas with her old friend, Joe, and a houseful of guests, but heavy snow puts paid to their plans. At first, she thinks they will be completely alone, but the arrival of Joe’s workmate, Ian, turns their twosome into a kinky threesome. With the aid of some antique sex toys they discover in a box belonging to Joe’s late aunt, they begin to enjoy a variety of naughty BDSM games, in the course of which Natasha and Joe discover the strength of their true feelings for each other
