Dear Diary,

I was taking a shower and heard what sounded like my step-sister moaning so when I dried off I went to investigate. I walked down the hall and caught my step-sister who is like 7 months pregnant getting off in our dads room! I guess her hormones were raging and she just had to have a orgasm! I figured i'd be a good big step-sister and help her. One thing lead to another and somehow we both ended up having super intense orgasms together.Only way to make it even better Diary was if step-dad walked in, and he did but ill tell you about that later!
