My stepdaddy is my sex slave Part III

I continue to make stepdaddy my pussy worshipping slave.

I knew that my stepdad was dying to put his little wiener in my pussy, but that was not going to happen until I had him under my full control. He had seen me naked. He had actually jacked off in front of me. He had spurted his hot cum all over the pool house floor when I stroked his hard little dick. Tuesday was a regular school day for me and a regular work day for Mom, but it was also Sidney's 43rd birthday. I was determined to do something very special that would make him even more of a slave to me. On Saturday I went shopping with two of my friends, and I bought a cheap "burner" cell phone. I flirted a little bit with Sidney at the pool on Sunday afternoon, but there were too many people around for anything to happen. On Monday night in the bathroom, I took a pair of scissors and trimmed off a good amount of my pubic hair. I saved it in a ziploc bag. Late Monday night when everyone was sound asleep, I snuck downstairs and put the cell phone, the panties that I had worn all day, and pussy hair in the glove compartment of Sidney's car. He regularly carried his lunch in a lunch box to work, so it was easy for me on Tuesday morning to volunteer to pack Stepdaddy's lunch box, and I included a handwritten note.
I don't know the exact time line of what happened since I was in school, but when Sidney went to eat his lunch around noon, the note from me told him to look in the glove compartment of his car. When he found the panties, pubic hair, and phone, there was another note from me with it. I explained how much I wanted him to have my pussy hair so that he could think of me, and I wanted him to put on the panties and masturbate for me in his car before coming home that afternoon. I wanted him to record a video of him masturbating with the cell phone and text it to me.
Sure enough, I had already arrived home from school and it was about 4:30 when my phone dinged with a message from Sidney. I went into the bathroom and locked to door so that I would have privacy from my little sister. It was a video from Sidney with a note attached that said "I truly love your pussy!" The video showed Sidney in the backseat of his car (I have no idea where he was parked) but he was completely naked except for my panties which he was wearing. Then he slipped the panties off and sniffed them and folded them around his hard little dick and began to jack off. He took the ziploc bag of my pubic hair and unzipped it and sniffed it as though he was sniffing my pussy. I watched as this pathetic little man made a complete fool of himself jerking with my panties until he finally spurted his wad all over them. I immediately texted him and told him how turned on I was seeing him and told him I hoped he had a happy birthday. I also instructed him to put the cum soaked panties in a cabinet in the pool house. I said that I wanted his "cum tribute" so that I could masturbate with it.
Sidney arrived home as usual and we had a birthday cake with supper. When we all gave him a birthday hug, I managed to rub my tits across his chest and pinch his ass. As you can tell, by this time he was too far gone to ever go back. He wanted my pussy. He needed my pussy. But I wasn't quite through teasing him yet. That night in bed, I nearly rubbed my clit raw thinking about the tremendous power that I now possessed. I pictured my stepdaddy wearing my panties and jerking his cock, and I had an incredible orgasm. (Stay tuned for Part IV.)
