My girlfriend and I recently broke up. Since then, I have been sneaking into her apartment after she leaves for work. I sniff the panties she leaves in the hamper. I go through her e-mail and Facebook chats. I downloaded all of the dirty pictures we took together but would not let me keep and even the ones from before me. I masturbate to porn on her computer and cum on the towel she uses to dry her hair every morning. It makes me feel ashamed and pathetic but I can not stop myself. I do this two or three times a week.
