When I was 14, I found out just how good it can be for a girl to sit on her dad's lap. I am an only child, of professional parents. My parents have always been openly affectionate with each other, and me with them. It wasn't uncommon for the three of us to share midnight movies and snacks on winter weekends, in our pyjamas, snuggled together under a blanket on the couch in front of the Tv.
One time, we were on a family trip at Christmas when I had just turned 14, and we were staying in a hotel because the family we were visiting had more company than they could handle. After coming back from an evening's visit, we settled in to watch a movie, I can't remember the title, something stupid but funny that involved Jennifer Lopez showing her thighs a lot. Because the only place in the room to comfortably watch TV was a loveseat, my parents and I were all sitting on that and me on my dad's lap.
It started out to be the usual, pj's popcorn, and blanket, but I usually wasn't sitting on my dad's lap, not that it isn't comfy. I'm 5'1' and about 100 lbs, and he's 6'2' about 220 lbs or so, and something to look at, according to my girlfriends, even though he's almost 50 now.
Anyway, after we'd been watching J'Lo gyrate for a while, I began to feel something hard against my butt, at first, I felt kind of embarrased, but I was also kind of turned on, from the movie and then from feeling the pressure of my dad's penis against my butt. I got up to get something to drink, and briefly considered sitting somewhere else, but didn't. When I sat back down on my dad's lap, the length of his penis was pressing against my slit. I could feel myself getting wet, and if I moved, it was like an electric shock going through the center of my being. Occasionally, when I moved, I could feel his penis twitching under me.
Fortunately, when the movie was over, the lights were out, so no one could see the seat of my pj's when I got up to go to bed. They were totally soaked as I'm sure were my dad's pj's, because he went into the bathroom and changed before he and my mom got into the next bed.
Usually, when we travelled, I don't think my parents had sex when we stayed in the same room, but that night they did, and they weren't particularly quiet about it. I normally wouldn't have masturbated when my parents were in the same room either, but believe me, that night I did. Listening to my parents having sex and thinking of the feel of my dad's penis pressing against my pussy.
