Like my other post says, do not get grabbed and step back and off the line of attack.

Nage’s back tegatana sweeps down and guides Uke‘s arm to waist-level and slightly out. Continuing the momentum, slide sideways with the direction of Uke‘s arm keeping it just out of reach from his hara. At the right moment, grab if with both hands and do a nikyo dosa toward Uke.

When I did these tonight it was satisfying to see the surprise in the Uke‘s eyes.
