I am a pervert. I admit to it. My current wife and I have been married only a few years and my sex drive is still pretty high while hers as gone kaput. What is there left for me to do but watch as much porn as possible and try my best not to stare to much at my wife's daughter who lives with us. It's pretty hard not to notice my step-daughter. She is almost twenty-one yet looks like she is younger, much younger. I have a thing for females in pigtails and my daughter likes to wear her pigtails all the time. This afternoon as I was on my way to the kitchen I heard a slight buzzing noise in my daughter's room. I didn't want to pry but I wanted to make sure all was ok in her bedroom. I opened her door to one of my all time favorite fantasies, my step-daughter in pigtails playing with her pussy. There she was, her legs open wide and the vibrating toy pressed against her pussy. She was in such ecstasy she didn't notice me watching her through the slightly opened door. I watched her long enough to detour myself right into the hall bathroom so I could rub one out. After I shot my jizz into a wad of toilet paper and cleaned myself up, I got a keen idea. I saw various attachments at my favorite sex store that go with that particular vibrator my daughter was pleasuring herself with. I could go buy her one of those attachments in hopes she might let me watch her use her toy a little closer to her than her doorway. I purchased the cute purple color rabbit looking thing, put it in a gift bag and could hardly wait to give it to her. I stood at her door with anticipation yet a little anxiety at what her reaction might be to this gift she was about to receive. She looked a little perplexed yet wasn't repulsed so I took it as a good sign I might get to watch her use it. Sure enough she plugged in her vibrating toy with the new attachment on it and held it to her pink panties. I could already feel my dick swell and move in my pants at the sight of her pleasuring herself with something I bought her. It wasn't too long before she said she felt weird being watched by me. It was fun while it lasted I thought and prepared myself to exit her room so she could continue her masturbation privately. She surprised me with an invitation to lie down on her bed and let her see what I have in my pants since I already got to look at her. She was clearly amused at my hard on, knowing she was the cause of it. When she wrapped her two little hands around my swollen shaft and pumped it, I thought I had to be the luckiest man on earth at that moment. She talked so dirty to me and said all the things I wanted to hear being the old man pervert that I am, or that she says I am. She gave me a better hand job than her mom ever did. The way she focused on my tip was nearly driving me insane. I didn't take my eyes off her tiny titties with those long nipples. She jacked me off with such fervor that my legs were quivering and I'm pretty sure my toes were curled. How could I not give every last drop of my cum to her when she asked repeatedly for it. She asked for a mess on her tiny little hands and she got it. As I lay there in my post cum bliss she reminded me it would totally suck if my wife found out about this, in same breath she asked for my credit card. Looks like this hand job is going to cost a little more than I expected. Starring: Amai Liu
