If BufReader takes ownership of a stream, how can I read and write lines on it?

I want to read a line from a TCPStream, write another line to it, and then repeat. The issue is that BufReader::new takes ownership of my TCPStream variable:

let stream = ...; // TCPStream

let reader = BufReader::new(stream); // moved its value

// can't use stream here anymore

What is a simple solution to this?
