She seemed to have a pre-constructed opinion of me, like she knew me. But I didn't recognise her. I'd never seen her before.I decided the next time I ...as horny at my desk to go a little later and see if I couldn't bump into her in the woods. Sub-consciously I suppose I had the fantasy that I'd be in the bushes with my pants down as she walked past on the path a little distance away, having left a little later and being longer on 'the job'.. what a thrill that would be. I might smell her perfume. She explains, “you see the part I’m rubbing sweetie? That’s called a clit-tor-is. It feels really good when mommy rubs it and it also lubricates her va-jyn-a,” enunciating the words carefully so I understand.“Mom, what’s a va-jyn-a,” I askShe moves her hand lower and plunges two fingers into her wet hole.“You see where my fingers are now? That’s mommy’s vagina. This is where you came out of when you were born!”My mouth gapes open. “How did I fit in there,” I ask enthusiastically.“Well it may. She was magic. You could fuck her all day every day.I spread Tina’s thighs with my knees and made her sit on my lap. My cock was still inside her. My chest was pressed against her back.I cupped her breasts from behind. Tina raised both her arms and grabbed her hair. She rose and sat repeatedly, my cock plowing her from below. Tina made sure that my cock went all the way up inside her every single time.Then I bit her neck as I finally came inside my friend’s sister. Both of us were so exhausted. "How do you know all this, Sarah?" I asked. She frowned."I don't know. I just do. I can see it in her. I saw it before, also. You know I see things, right, just like Sammi?" She blushed prettily for some reason. "Well, maybe not just like Sammi..." Hmmm. I was going to have to ask more about that later; it sounded interesting.We all went into the living room and sat down, chatting about inconsequential things while we all tried to recover from our fright of what had just happened. We invited.
