Then start your next pomodoro immediately. That's what I do. If you can do that and not get burned out, that's ideal, especially if you're in the zone. It's also better than increasing your pomodoro time IMO. Since I don't take a break 2-3 sessions at a time sometimes, looking at 10 minutes to go is spurring; when I experimented with 40-minute sessions I hated looking at 35 minutes left on the clock.

I do a variation of this. Ten minute timers, instead of 25, and then I make sure that whatever task I set for myself is something I can do in 10 minutes. For programming tasks this is often "Finish writing method foo", or "Debug the problem with method bar".

How long are your breaks?

I don't take a break after every session. I usually try to break for 5-10 minutes once per hour.
