I have had an unhealthy sexual obsession with my sister in law for almost 10 years now. I reapeat, obsessed. I love my wife dearly, and I can't imagine the thought of ever leaving her. Which is why I'm posting this. My problem is.....I can't stop thinking about shooting my cum all over my sister in law's face, over, and over, and over. She's got great sometimes tan skin, a great body, and most importantly an incredibly sexy, shiny, well structured face with no blemishes. She was made to take a hot load to the face. She's not always the nicest person to other people, but my god she is so amazingly sexy.

* I've used Photoshop to fake many pictures of her. I've made her almost completely naked, but most of the pictures I have faked are pictures of her with cum all over her face. I've made some public requests asking others to make some fake pictures of her with cum all over her face, most of them have been mind blowing. My wife almost found the pictures once. Both sites I used have since been taken down.

* I wrote a short erotic story about her with the bulk of the details surrounding how I shoot the biggest load of my life all over her face.

* I jerk off to pictures of her, both real and fake, total of 36, as well as my short story, at least 2-3 times a week. These are well hidden on my computer.

* On the beach (with her husband nearby) she said "Happy Birthday" while taking off her clothes, revealing her sexy bikini.

* She came to visit us at our apartment and slept on the couch. I woke up early that day, went to the bathroom and left the door open. Then I jerked off to her in the bathroom while watching her sleep.

* Another time at the beach, she was rubbing sunscreen lotion on her face, then paused to talk to some people. The way she left the sunscreen looked like cum. It was incredible.

* We played the game "Pie In The Face" with a group of people once. She got hit by a shot of whipped cream all over her face. I jerked off so hard to it later that night. Just watching her face prepare in anticipation, the white cream covering her sexy face. It was one of the hottest things i've ever seen.

* My hugs with her at family get togethers always seem extra long, like she really pushes into my body with hers. It's sometimes borderline too long and I wonder if other people are watching. The best ones are always when she's wearing something in hot weather so I can feel her skin against mine. I wonder if she can feel my semi boner against her?

* There was a picture of me taken at Christmas where i'm sitting in a chair, talking to someone. She's either just smiling at me, or checking me out hard, either way I love it.

* She likes to get on her knees a lot. Every opportunity I can I find a discreet way to walk by her and imagine shooting my cum all over her face.

* One time my brother in law left an SD card with some pictures that my wife and her sister took from an event. My wife was going through the pictures and found a folder that said "Private" and told me about it, laughing, saying "I'm not going in there lol". I've never been more hopeful to see naked pictures of her. I woke up 2 hours early, while my wife was asleep, and stealthily, nervously, checked the SD card and went straight to the "Private" folder. There was nothing sexual there, just some random family pictures. I was so disappointed, yet jerked off at the thought of actually seeing her naked regardless.

* In a few weeks I have to go to her house, down the street, while her and her husband are away to take care of their dog. After that I'm planning to go into her bedroom and jerk off hardcore, multiple times, with her panties.

* Even now, as I'm writing this, I'm jerking off to the thought of all these past sexy events, with her sexy pictures in the background.

I have a real problem. I don't know if I can get her out of my system, unless I have ravenous sex with her and shoot the biggest load of my life all over her sexy fucking face. Just once. Sadly I know it will never happen, even though I want to try so god damn bad. Any advice for what to do to get her out of my system would be greatly appreciated. Thank you all for taking the time to read this post.
