Secretly watching my boyfriend's porn

I am turned on by people doing things they know to be "wrong", such as cheating, masturbating, and anal. Now, I know those aren't necessarily bad things, but as a kid I believed them to be bad and it's like a kinky taboo to me. As a kid, soap operas would turn me on so much I'd have to lock myself in my bedroom to masturbate. Fast forward 20 years and that shit still makes me so hot, but instead of watching soaps I like to go through the Internet history on my boyfriend's phone. I feel like I'm doing something I shouldn't do, and my heart races while I try to look through everything before getting caught. I love looking at all the porn sites he gets off on. I love to see what turns him on and I think of ways to recreate what he's secretly watching. It makes me so wet that whenever he comes back into the room I can't control myself. Sometimes I even touch myself and get off before laying him. He has no clue, he just thinks I'm really turned on all the time.
