Quick and careful punches

As Emma staggers backwards you continue to pummel her with several fast punches. Emma lets out a painful grunt every time you snap her head back. By the sixth or seventh punch in a row your opponent fell to her knees. "Had enough Emma?" You asked confidently. To your surprise she shook her head "no" despite being clearly exhausted. Truth be told you felt tired yourself. You looked for something to tie the villainess up with.
