Her back was to us and he reached around with both hands and grabbed her well under both her cheeks giving him a great feel of her ass and lifted her up and pulling her into him. She did not move away just danced, it was more like a hug as they were not moving much.
when he got her on the dance floor he dance very close to her, no space at all. A couple of weeks ago we were out dancing with another couple and near the end of the night a guy 20yrs younger put his hand out between both ladies and my wife took his hand to dance.
