Well Ultear seems to be obsessed with Zeref and there was no way for her team to know she was cuddling him, nor would they have any reason to stop her considering they weren't worried about losing the Guild War. Also Ultear is responsible for bringing him back, and she did stop her cuddling and was in route to doing before she saw Gray.
