This started out with a girl my age, about a year older but still in the same grade, who happened to be my friend's girlfriend. He's a real nice guy but he lets his girlfriend, Annabel, get away with a little too much flirting. To make matters worse, she admitted that she was bi while dating him. I felt bad for him but she flirted with everyone, including me. I was a little uncomfortable at first, but then I got used to it since it was a part of her personality.
Anyway, this happened one day while I was at the playground with my best friend Katrina and Annabel. It was getting a little bit dark, but we live close so we stayed out. We were all bored, so we decided to play hide and go seek. 'Not it!' I came in first, Annabel following, and Katrina became the seeker. 'Count to 200, Kat, I'm a slow walker,' Annabel teased Kat, then ran to go and hide. After I concealed myself in someone's backyard, I heard the door creak. I stayed completely still, trying to keep my breathing down. I felt someone grab me from behind, only to find that it was Annabel. 'You scared the crap outta me, Anna! What's wrong with you?' I said in a loud whisper, but she kept herself behind me, holding me tight.
After five seconds, I was beginning to feel a bit strange, my panties becoming a bit wet. Anna went down to my neck, giving me a soft kiss, and I could feel her humping against my back. 'If this is a joke, I don't want anything to do with it,' I said, trying to escape her grasp, but she was a good two or three inches taller than me, and had the advantage since I was pretty small and petite. 'I'm completely serious right now, Ash. I'm super horny and Kat will never find us back here, so can't we do it once?' She whispered in my ear, biting it after she finished speaking. This was a major turn on and I squirmed a bit in Annabel's arms. She began to reach underneath my shirt, and grab at my rather small 34B boobs. First she cupped them in her hands as though she were measuring them or something, then began to rub hard on the nipples through the bra. She put her knee in between my legs while fondling my boobs, and began to rub back and forth. I was soaking wet down there by now, and secretly hoping that this was turning her on too. I turned around in her arms, causing her to pinch on my nipples a bit then let go. I brought my mouth to her lips, as she kept her knee in between my legs, rubbing back and forth. With one hand, I grabbed one of her 34C boobs, and reached down to rub the outside of her jeans with the other.
I had her shaking with delight, and she had me begging for more. I came, and a minute or so after that, she told me that she did too.
I have to say, that was one of the best times of my life, but I still feel a bit bad for my friend. I hope he doesn't mind that me and Annabel still do it every now and then too.
