The sin of flesh - KOH.

Her fingers brushed deftly over his aching skin, across old battle scars and patches of skin left reddened and dry from his affliction, eyes wandering over the expanse of naked skin before her, weeping wounds and skin pulled taught in effects of trying to mend itself only to be ravaged by his disease, she massaged the balm into his skin with care, her eyes never wandering too far from her next task.
And his eyes never leaving her hands, hardly moving when he takes in the swell of her backside, back arched as his eyes dragged across the expanse of her body unknowingly, his somewhat predatory gaze hidden by the shadow cast over his eyes by his silver mask, who knew that the daughter of opposing faith could look so beautiful treating his wounds? Who knew the swell of her backside and the feeling of her breasts brushing lightly over his slightly raised knee would feel so right? Sin, he could hear a voice in the back of his mind, his eyes flickered to the face of concentration he was sure to see for weeks to come, a face he'd soon grown quite fond of seeing since her unexpected arrival to Jerusalem, his lips parted slightly, wetting over the cracked and dry expanse of them with his tongue, taking her in full, 'I am yours, whether physician, confidant or sword, I am yours until you are healed' the words fresh in his mind still.
Oh, had she only known how he thought to sin for her, how he thought to feel her body pressed against his.
Had she only known the sin of flesh he'd be willing to commit.
