Colleague who shares his nude wife photos and videos online

My colleague was on leave and had to search for some document in his office computer. So I just opened a word document and found nude photos of his wife pasted in it with detailed description of her b****** and p**** and from the language it was addressed to strangers to comment and sent c** tributes. I further searched of video files like mp4 3gp etc. and found a folder with many p*** and nude photos of many girls. I copied all such material to my pen drive. Later I added some of my own homemade p*** without depicting my or my wife's faces for him to enjoy and share with his online stranger friends..
