Finally the fucker is going to sleep. I'd had celestial punishment brought down upon me in the form of my in-laws visiting for a week and was just about at my limit. Like their daughter, my wife, my in-laws were devoutly religious and had always resented me for not sharing their views. Spending time with them had always been a chore but at least when they still lived on the other side of the country our interaction was limited to once a year or so. But a couple of years ago they had decided to move closer and were now residing just a couple of towns away in order to see more of their daughter and grandchild. This was the worst combination possible; they were close enough to visit much more frequently than before, but simultaneously lived too far for them to come for a day and then go back home for the night. It was day three of my current ordeal, but at least things were looking up as my father-in-law was heading to bed at a reasonable time which meant I was no longer obligated to keep him company that night. As I mumbled good night wishes I kept my excitement to myself; my wife and her mother were long gone, and my daughter Mia had headed up to her room just a little while ago. The timing seemed perfect. Good job too, my balls were aching from watching Mia scamper about in her next-to-nothing summer outfit and I desperately needed release. I was hoping I was in for another of Mia's little shows tonight.
I heard Peter close the door to the guest room my in-laws were staying in and caught a snippet of my mother-in-law snoring like a bent chainsaw. "Jesus woman, you need to look into that" I thought absentmindedly as I started my computer up. I even felt a little bang of sympathy for Peter for having to sleep in the same room; maybe the man is such a sanctimonious asshole because he hasn't slept properly in 40 years. I keyed in the password I'd recently put in to protect my computer from prying eyes and logged into the nanny cam. My daughter's room came in to view with my lovely little Mia laying on her bed, evidently texting on her phone. I looked at the clock and wondered who she would be texting at this time of the night and felt a little jealous thinking it might be some guy that was trying to get into her pants. "Surely I had the right to be in her pants more than he did" I caught myself thinking before realising how absurd that thought had been. But I couldn't help it, after weeks of spying on my slutty daughter I was no longer feeling any remorse about it, only lust. My fatherly emotions seemed to have evaporated and been replaced by feelings men should reserve only for the women they're trying to have sex with. Rationally I knew it was wrong, but I felt that any man who saw my gorgeous Mia would understand me perfectly.
Gazing at my little bunny laying on her stomach on the bed with her ass straining against her tight jeans I could feel my cock happily getting back into the routine it had gotten used to by now and soon my own jeans were being stretched too. After a little while Mia snapped her phone off, slid off the bed and walked in front her mirror. I knew this routine by heart now, but that didn't lessen my excitement, if anything I was gagging for the show even more knowing what was about to come. I watched Mia slowly grab her shirt and pull it above her head revealing first her tight stomach and then her lacy bra that was struggling to hold her full breasts. She threw her shirt towards her laundry basket and the movement caused her tits to jiggle in a way that forced me to unbutton my jeans and let my cock out before it ripped through on its own. Mia was looking at her reflection and slowly unbuttoning her own jeans unaware that she was following suit with her daddy and slowly her round ass came into full view as my cock started dripping precum as if on cue.
Suddenly something was wrong. I couldn't figure it out first and thought for a second the camera was acting up. But as it turned out it wasn't the camera acting up, the movement I thought I saw in the corner of my eye was real. A figure I couldn't fully see due to the direction the camera was pointing was standing by the doorway. Mia had logged it too, but instead of being shocked like her old man I saw the familiar little smirk spread to her lips as she continued to work her jeans down her legs never breaking eye contact with the intruder. She kept her legs straight and lowered her upper body to ensure her delectable ass stayed in the air, just begging to be violated. I sat frozen, fighting my urge to stop whatever the hell was happening to my baby girl and the urge to watch how it turned out. My cock won, again. She clearly knew who had come in and wasn't afraid, and even though some punk getting into my house to spy on my daughter wasn't a thought I was comfortable with nevertheless I just sat there like the voyeuristic little pervert that I was.
Mia stepped out of her jeans but her ass stayed up while she placed her palms on the floor. I could see her talking to the stranger who finally walked into view. My hand froze on my cock as Peter walked to her granddaughter and pushed his crotch against my little princess' ass. Mia kept to her position but I could see her slowly grinding her panty covered ass against her grandfather's crotch while Peter started kneading her cheeks with his large hands. I watched this clearly long-established routine folding out before me cursing this hypocritical motherfucker while simultaneously cheering him on. My cock was definitely on Peter's side, and I took my hand away in order to enjoy the bittersweet pleasure a little longer before blowing my load.
