StepDaughter Liked To Watch

Now divorced...my 2nd wife's daughter used to sneak a peak while her mom and I fucked. I found out at 14 she started by listening as we fucked. She eventually would open the door and peak. I wondered why our door was often open after we finished. One day I saw the door open out of the corner of my eye. I could see her watching. Majority of times after that, she would watch. One time when my wife was buttfucking me with a strap-on, she saw the door was open and freaked out when she saw her daughter watching. After that, she tried putting things against the door and eventually bought a locking door knob. I told her it was the wrong one and never installed it. When my stepdaughter was 16, me and a buddy were spitroasting my wife when I saw the door was open. After a while, her mom noticed and tried to get free. We made sure to keep a good grip on her and fuck her harder. After multiple orgasms, she was too exhausted after we both came in her to do anything. My stepdaughter was standing in the half-open doorway with a hand down her pants as we wiped our cocks on her quivering mother. Her pants wer soaked and she just stared while rubbing herself. After that, her mother quit trying to keep her out. Didn't matter if my wife and her sister were spitroasting me with strap-ons or if her mother was getting an all-holes-filled gangbang, if my stepdaughter was home, she was in the room watching. Often getting up close...like REALLY close. She usually wound up partially or fully naked and masturbating with fingers or using either her mothers or my sex toys. One fateful day while her mother was having an all-girls orgy, her now 18 yr old daughter joined in. We found out then why she never wanted any of the cocks that fucked her mother. She was lesbian. It was all about watching the women, not the fucking. It was a hell of a sight seeing my step-daughter get spitroasted by a women including her mother and aunt. After that, she would join us to house parties and swing clubs.

I'm no longer with her mother, but we talk often and she has developed bi tendancies. She is fine getting fucked by a guy as long as she is eating a pussy.
