I always wanted to see this scene from the books.

When she emerged from the lake, shivering and dripping, her handmaid Doreah hurried to her with a robe of painted sandsilk, but Khal Drogo waved her away. He was looking on her swollen breasts and the curve of her belly with approval, and Dany could see the shape of his manhood pressing through his horsehide trousers, below the heavy gold medallions of his belt. She went to him and helped him unlace. Then her huge khal took her by the hips and lifted her into the air, as he might lift a child. The bells in his hair rang softly. Dany wrapped her arms around his shoulders and pressed her face against his neck as he thrust himself inside her. Three quick strokes and it was done. "The stallion who mounts the world," Drogo whispered hoarsely. His hands still smelled of horse blood. He bit at her throat, hard, in the moment of his pleasure, and when he lifted her off, his seed filled her and trickled down the inside of her thighs. Only then was Doreah permitted to drape her in the scented sandsilk, and Irri to fit soft slippers to her feet.
