This is probably more FM, but you can make your own mind up.
A hot Sunday, and a game of cricket in an English park. Cricket is not the most fast-moving of games, and I sat on a bench, to be honest, bored.
Around me there were others watching the game, some couples on blankets having a picnic around the outfield, and others making out.
I saw one couple who were so wrapped up in each other, for them, no-one else existed. They were kissing deeply and his hand was traveling up and down her thigh. Each time, it would explore a little higher and I found myself willing him to put his hand up her skirt. He did, but oh, it took ages. First fingertips disappeared, then reappeared, then the whole of his fingers, the tension was amazing and I found myself getting really horny.
I was dressed in a short loose summer dress and I let my knees open a little. As he kissed her, he flicked up her skirt, revealing her black panties underneath. Then, he took her knee and drew it over his waist. I wasn't close enough to tell you that she was wet, but she didn't stop him, and she must have known anyone looking over there would have seen her.
Then, I saw his hand dive down between them, and by the movement of his fingers under the crotch of her panties, it was obvious he was fingering her right there.
My breathing deepened, and I felt the unmistakable wetness start. Then, he broke off from kissing her and looked up, right into my eyes! His fingers kept working her and I spread my knees further. He would have been able to see my crotch, and I was certain my blue panties would have looked dark over my pussy.
By now, her ass muscles were clenching and unclenching from time to time and then it became rhythmic. He stared at me and I willed him to look between my legs which he did.
I opened my knees as far as my dress would allow and let him stare at my pussy which by now was literally dripping. As his fingers moved, I imagined I could actually feel what he was doing to her.
Then I saw her ass muscles tense and her head lifted from the blanket, she held perfectly still for what seemed like minutes, but could only have been seconds then her whole body started a series of convulsions as she came on his fingers.
To my surprise I was at the point myself, and I wanted him to see me. I reached up under my skirt, tugged my panties aside and, I swear, only gave my clit a couple of flicks before I had the most amazing orgasm of my life. Hard, harsh, violent, gut-churning, and squirty! He must have thought I had peed myself, but I gave a good couple of long squirts that stained the concrete in front of me.
I have never been that aroused by porn, but seeing him finger her did it for me BIG time.
I am definitely NOT bi, but I would have walked over to them and done the pair of them right there and then on that sleepy little village green.
I didn't give a shit who saw me or what they thought, any more than that couple did.
Shortly afterwards, they walked into the woods, no prizes for guessing what they did in there!
