<human>: So for those that don't know, you can use the same Xbox live account on the 360 and the One at the same time. 

I don't use my 360 anymore because I upgraded to the One. So I figured I'd be a nice big bro and let my sister use my profile (because it has live on it) and the console. She likes to play cod zombies, fable games, and skyrim. 

Here's where the F U part comes in. She has a boyfriend who also plays. So because I am on the same profile on my Xbox One, I receive all text messages that she receives on the 360... These are messages I didn't want or need to see. Her boyfriend was making, let's say, "sexy talk". And from what I gathered it was going back and forth because there were multiple messages from him that would indicate that my sister responded in a certain way. 

I honestly didn't read past the third message because I was getting grossed out and felt like I was violating her privacy. So I deleted the rest that came in and it hasn't happened since.

Summarize the given text in a few sentences.
<bot>: my sister used my Xbox profile, sexted with her boyfriend and I saw all the messages from my Xbox One.
