There in the back of his desire addled mind the Space Marine earnestly wondered if he had really died back on Mars, and was now in heaven. He hadn't ever really been one to believe much in an afterlife, yet the between the magical barrier covered town, and having met someone so utterly amazingly unique as the Doctor...some small part of him had to wonder if this was real.
His body shook and trembled as if to say that it voted yes to this being real; and the way she worked his length made it hard to argue with that at all. Between the bobbing of her head, and the wicked way her tongue lavished his cock with care, a bit of pre was already spilling from his tip. He wanted to move, to touch her, taste her, to make her moan again. But as he stood there Reaper found his movement restricted. Just the feel of her hand around the base of his throbbing member kept John standing right there before her.
Still a single shaking hand of his moved at last; fingers gently sweeping through her hair, until he could caress her ear and trace his fingertips lovingly across her earring. For all his strength she was in complete control of the Marine, and he shamelessly moaned her name aloud. Uttering it like a breathless prayer.
