It's a great story, and pacing is OK. I have two things however that I hope get implemented, or changed...first, the MC and his moral hang ups is a bit over the top for me...the girl living with him, ok, I can go with his extreme moral high grounds due to the fact that he raised her from birth. The other two girls though, specially Becca...I don't see how having such high moralistic values, like seeing them as if he is their biological father makes sense...if anything, seducing and having them fall in love with you romantically would be a very real revenge plot for what his ex wife did to him.
Second, the story needs a protagonist..this could have been easily the ex wife, and the dickhead that kept banging her, even after they were caught. There is a lot of potential for juicy plot twists, whether it's revenge on her, or her lover...or her against him for her daughters not hating him as much as she does.
Otherwise, good story, looking forward to future releases.
