Want to use a vibrator in doggy style

Hi, my wife and I recently started using Tracy’s dog vibrator for missionary sex. I use it to stimulate her clitoris when we have sex and it brings her to orgasm every time. She loves it. We have tried using it in doggy style but I have a hard time keeping this big vibrator in place. She wants me to hold it and then stimulate her with it. It’s hard because I need to keep it at the right angle and position haha…but it’s almost impossible if I’m thrusting. Is there a vibrator that’s easy to hold when I reach over to her from behind? Might need to place my hand very close to the control area. Other ideas to achieve this are also welcome. Like crotchless panties that can hold the vibrator? Thanks!
