I also work longer hours on average when working from home, but I don't really mind it. The main reason is that I save easily 90 minutes of commute per day, so it's not bothersome to be available some of that time extra. And the second reason is that I take personal breaks randomly during the day, I'm not always 100% focused on my work, so I don't feel like being available a bit later is a stretch. Flexibility goes both ways.
