I enjoyed this story and the last one more than the first two because there was some actual relationship building and character development in them.
Vaguely Sci-fi, but with almost no world-building or descriptions of spaceships, planets, or anything except the characters' special manly parts and their hot man-luvin. In other words, really should be classed PWP. In the way of most claiming stories, consent issues abound if those bother you.
