Public groping

Any ideas on places to go to get the wife groped by random strangers? Any experiences with this type of play?
I’d love to see her be touched inappropriately and watch the men’s reactions as she smiles and welcomes them to do more.

When I was with my exgf, she used to do this when she got a bit too much to drink. I could tell when she got horny because she would come up to me and say "I am going to the toilet". She always came back with her tiny panties in her hand and put them in my pocket. She would then go dancing on the very crowded dance floor and wait until she was joined by a guy or guys. I used to wait in a certain spot where I could see her through the crowd. She always wore very short skirts or dresses for easy access. As the guys crowded her she would back into one of them and dance with her hands behind her back so she could initiate the first grope. After wanking the guy behind her he would usually go under the hem and play with her bare, shaven pussy. Many times I have watched her on the dance floor with her juices running down the inside of her inner thighs, glistening in the disco lights. After a few dances she would then come up to me and kiss me deeply with the guys in tow, but they soon fucked off when they saw me.
She only fucked 5 of the guys. She would come to me and ask if it was OK to go to the car park and fuck the one she had pulled because he had a big cock. We had a lot of fun doing that
