My BP does this pretty often. As far as I've noticed with mine (a fat snake is a happy snake within reason), feeding every five does on a good meal, they might be like us after we get full (just want to lounge around).

As long as it eventually drinks water and doesn't lose a noticable amount of weight he'll be fine. I'm not breeder or expert so take this with a grain of salt, there are a lot of people here who obviously know more and can help you better.
