Sex with Excalibur. Canon.
She straddles him in their bed, easing up and down on his member, rocking slowly, languidly. Decadently. Savoring their time alone together in the solitude of their chambers before he has to ride off again.
Her eyes open, heavy-lidded with desire as they gaze at her husband beneath her, his own eyes blissfully closed, his mouth open, his breathing heavy. His hands slide up her thighs, up her stomach and caress her breasts, skimming his long fingers across her stiff nipples.
She sees his favorite sword, Excalibur, gleaming, freshly cleaned and polished, lying on the bed next to them where it landed when he tossed it there earlier, having entered their chambers just as she was exiting her bath.
The sword is tantalizingly close. She thinks she can reach it. She doesn't know why she wants it. But she reaches, closes her slender fingers around the handle, and pulls it to her.
He opens his eyes as he feels her slight weight shift in a different direction. What is she doing?
He watches, mesmerized, as she runs her hand along the blade, softly, taking care not to slice her palm. The blade moves and occasionally he sees glimpses of his reflection in the shining metal.
She strokes the blade as if it is another part of him. An extension of the part buried deep within her. Still she rocks atop him, stroking his shaft, stroking his sword.
She slides the flat of the blade down, running it along her arm, dragging it over her flat stomach, grazing the undersides of her breasts.
He does not worry that she will cut herself. He watches still, lifting his hips to meet her as she moves. He feels the cool metal glide across his stomach, his chest. He watches it as she very carefully slides it over her breasts, then between them.
She opens her mouth and whimpers, then licks the length of the blade with her small pink tongue.
His hands tighten on her hips and he comes then with a mighty groan, his fingers digging into her supple flesh.
The sword clatters to the floor a moment later and she collapses over him, whispering his name, her fingers in his hair.
