Forget the sex and deal with the tease, lots of teasing...twins. This started life as a normal doover that is just a weird phrase); that didn't work so we have a do over of a do over. If you are looking for well plotted with lots of sex go somewhere else. If you are looking for a different read with a borderline stream of conscious style and lots and lots of information about boats and Michigan and planes and hamburgers then sit right down and read the story.
Unlike almost all of the long stories I read Old Man with a Pen often posts two chapters a day, I really appreciate that. As with most of what is written for this site there is a requirement for a suspension of disbelief. David is sent back by the military, he talks when he is born, he knows all kinds of martial arts, he's a kid. Master's Degrees for both of them at 15 or 14 or 12, hard to keep track. That pisses me off, teenagers getting their master's; I'm 67 and two semesters shy of my MA, but I am working on it. Twin geniuses, she's hot and horny, he's just horny. Will they, won't they yes, no,tease,tease,tease?
There are almost no typos or spelling errors or misused words,and that makes a lot of difference in my enjoyment.Now that he has posted Chapter 83 I may just go back and re-read the whole thing again.
