This is a very intresting premise. By changing one small thing (in this case having Clark be affected by the pheromone spray) you have developed a story that has endless possibilites. While other stories have been written about Clark being affected by the spray, I am not aware of any stories where a child results.
This story is very original and I look forward to reading future parts. As of right now, I am wondering several things:
When Clark learned Lois was pregnant, did he tell her his secret?
How did Lois and Clark's relationship play out?
How did Luthor come in to the fray?
I suppose future parts will (hopefully) at least touch upon these points.
