Mounted.cifs with ro option, user still able to touch

I got following setup:

me@PiWi$ sudo mount.cifs -o user=me,ro //192.168.1.101/media/Data/Games ./Games
me@PiWi$ ls ./Games/ 
Afdrukbaar  Console  Dos ScummVm  Windows
me@PiWi$ touch ./Games/Ishouldnbeable
touch: cannot touch `./Games/Ishouldnbeable': Read-only file system
me@PiWi$ ls ./Games/ 
Afdrukbaar  Console  Dos  Ishouldnbeable  ScummVm  Windows
me@PiWi$ stat ./Games/Ishouldnbeable
  File: `./Games/Ishouldnbeable'

As you can see I mounted the CIFS as ro but am still able to write to it. I tried to use the noperm option but it didn't resolve the issue. How come and how do I fix this...
