For me, Pomodoro is a technique to help you get started, and to focus. Vs procrastinate all day.

For the case you mention, I would adapt the technique to whatever benefits you the most. If you're in the flow, defer the break. If you defer too much, and start feeling burned out, adjust.

For some people, 25 minutes is too long. Find what works for you.
