So She can log in her own account in my PC?

My girlfriend is coming to my city in some weeks and we pretended to play together in the same house, obviously in two different computers, at the same time. But we asked ourselves if this could ban both of us since we are going to use the same network acess, IP and so. Can someone help me with this? I didnt found any admin that i could ask. How can I get any information about this situation i got?
