2 motor circuit, the main motor will be going forward

cirduit

Hi gang, again I need your help.
The objective is: the main motor will be going forward. When that motor is going forward, the second motor will do nothing.
When the main motor reverses, the second motor needs to turn ( doesn't matter which way it turns) For the life of me I can't figure out how to wire in the second motor.

A little info on my setup.
Both motors will be powered by one AA alkaline battery. The main motor"s direction is controlled by 2 5v spdt relays with the coils wired parallel.
The relays are triggered by a dark sensor.
( an ir emitter/detector circuit controls the relays)
I tried putting a diode on the negative terminal of the second motor but that ended up shorting the power supply for the motors. I suspect it shorted because of the cross over in the relays for the polarity reversing.

If someone out there can help me out, It would be greatly appreciated.
Thanks
Bill

gnomeman,
When the relay is in the Forward state, the 2nd motor has both terminals connected to the + battery terminal, so it doesn't run.

kral, thanks for your responce.
I had a hard time applying your diagram to my situation (I'm sure it's me).
But what you said did make sense to me.
I hope you don't mind but I modified your diagram to make it closer to what I'm doing.
In your diagram, I put the relay contacts and the wiring to the motors.
From what you said, I think the way I modified the diagram will work. If you can, look orver it and let me know if it will work.
Just as you said, when the main motor is going forward, both terminals of the 2nd motor are connected to positive. When the main motor reverses, one of the terminals of the 2nd motor will change to negative and the motor will run.
Thank you so much.
Bill

gnomeman,
Your circuit should work.
