"I'm one of the pledges, Serena," she said, "I received instructions to come out here for the next challenge."The woman's mouth curved into a smile."A... yes, you're the first one which is both good and bad," she said, "You'll soon find out which when you go inside." What do you mean?"The woman rubbed her sleek arms."As I said, you'll find out when you go inside," she said, "Show me a copy of the message and I'll open the door."Serena dug around for it in her purse, easy enough and produced it to. Or so Tom thought! As the train leaves the station the girl suddenly re-appears from behind him. “Looks like we are the only left in the carriage now, mind if I join you?” She asks. But before he can answer she brushes past him, plonks herself in the seat opposite him and throws her back on the window seat next to her.Immediately Tom notices that the next button down on her blouse has been undone and from the flashes of bare breast he was getting, as she starts to take off her blazer, it was. I took her clit into my mouth and sucked between my teeth, letting it slip out and then pulling back in between my teeth. Her body began to tremble again.I backed off a little, but then started to massage her vagina with the tip of my index finger as I continued to suck and lick her pussy. Soon, I was gently sliding my finger in and out of her. Caitlin was getting visibly excited. I massaged her clit with my tongue as I rhythmically eased my finger in and out of her pussy. Her moans got louder;. Her tits were firm and sat high on her chest ... a flat tummy and a heart shaped ass only just hidden beneath a mid-thigh length flowery skirt.When I'd met her for the first time this afternoon, I thought that she looked familiar. When she mentioned her last name was Midders, I realised that I didn't know her, but I did know her daughter Tammy. Tammy and I had attended the same school, and we had shared a mind-blowing fuck one afternoon after spending some time in my mum's spa pool.I wondered.
