<human>: So my girlfriend told me today that her step father yesterday touched and slightly squeezed her breast for a few seconds, remarking that they were soft. I questioned her further and found out, that he has been doing things like that since 2012. She's 16 now. About once a month he would touch her breast or butt, sometimes remarking how big or soft they are. It started in 2012 and has not escalated since.

It is an utterly disgusting thing to do and obvously I and her want it to stop. Questin here is what can we do?

Obvious answer - tell her mother. She feels that it won't help. She thinks her mother has seen him touch her butt a couple of times and hasn't really done anything. And her relationship with her mother isn't that good. Besides she's pretty sure that even if her mother would tell anything to the step father, it wouldn't help. I kind of agree with her because my girlfriend had a cat that the step father didn't like and was abusive towards. Her mother told him to stop being abusive, but he didn't care and now... The cat died of some injury... So telling the mother wouldn't make much difference, if it wouldn't make it worse.

Another option is informing CPS. However, I am not living in USA and the system here isn't quite working properly. Laws are too soft and chances are they wouldn't give too much shit. I've been in a situation were a person close to me died under very suspicious circumstances, but police ended up not doing anything useful. So I kind of think this has a potential to worsen the situation...

I live in another town than my girlfriend. I can't meet her that often and have never met her parents.

I am fuming with rage, disgustment and helplessness. Looking at this what can we do? Do you have any tips that would make him not have that urge to do it? Anything else? Any advice is appreciated.

I believe some tips that would lessen that pervert's urge for touching would help. For example my girlfriend could avoid him or wear clothing that would hide her breasts and butt.

Give me the gist of the text in a nutshell
<bot>: My girlfriend's stepfather has been touching my girfriend's butt and breast about once a month since 2012. Her mother and CPS are risky choices. What do we do?
