It's my understanding that once they start to reach sexual maturity and their hormones kick in that males need to be separated or they will fight/torment each other. It sounds like the bigger one might be trying to show dominance over the smaller one by mounting him? I know that dogs do this as part of their social hierarchy but am not sure if that is normal hedige behavior as they are not social creatures like dogs or primates. I would do what others have suggested, move them apart, buy a second set up including a wheel, and only put them together for supervised play time.
It sounds to me that either your breeder doesn't know as much about the species as they thought they did, or that something was miss-communicated. It's possible that they meant that the boys would be okay together for a few more weeks. But two adult males should never be housed together.
