Cool idea for a story. Something that I wish I'd come up with. Since we know what is going to happen, there isn't a whole lot of tension. This leads me to think this should have been written in 3rd person. While it's nice to hear see his bent mind and the way he thinks about the kids, it would have been more disturbing to get all the description of the monsters body too, also while this story is great the way it is, fleshing it out to 10 words and more little parts, maybe if he intimidated the pet child a bit, or smelt the rotten air of his kitchen, glad to be home. These little touches make something breath a little. I'm rambling now, theres some other things that'd be cool to add in but they might be a bit too messed up. If you wanna know what I mean read "the last train" a story of mine. It's a lot more graphic. Good work and keep writing, I'm always on the look out for good monster horror
