I saw this movie in 2013,

It was a English movie,

I downloaded this movie from utorrent,

It was color movie,

In the movie there was one girl who chatted in computer with someone and seduced him by his chatting questions, she also took her naked body part photos and sending him one by one, day by day she was addicted of sex and trying to do sex with one plumber/labor who visited her house for some work. When she got curious then she also trying to find out this man who chatted with her everyday, she met one lady who gave her some hints about this man.

And I think at the end that man was dead somehow.
