.. why?" I asked, shocked at such a random question."Tell you what, my daughter is at school, the original photoshoot for today was cancelled anyway, ...et's just both take a day off!" Sasha suggested. "No one will be here for hours. Are you in?"It was an offer I couldn't refuse, but wasn't expecting to be asked. "Us... both... skinny dipping... naked... here?" I wanted to check I heard Sasha correctly. "Well, you've seen all of this before!" she said, waving her hands across the top half of her. Thu bent forward and placed her hands on the low wall, stood with her legs apart, presenting an wide open path, I slipped my cock into her wet vagina and fucked Thu standing up, from behind. Thu loved the feeling of the full length of my cock entering her body stretching her lips and filling her vagina, crushing the head of my penis against her cervix. We both watched the young girl as she masturbated and watched us fucking, a sort of remote ménage a trio.Thu's breathe jolted with each thrust. I asked how her garden had done this year. She told me that she had picked more peas and tomatoes than she could use, so she gave the extras to the neighbors. "Momma, are you lonesome by yourself?" I asked her."Sugar, the best times of the year are when you and the girls come to visit," she told me."Would you like to come and stay with us, some? Our place is very primitive, but we are happy there." Yes Ricky, I would love to come and stay with your family," she said."Okay, come with me and we. But then, for the first time, she saw me, the explicit concern and barely concealed lust in my eyes. She smirked slightly, almost curtseyed to her unwavering audience (me) and began to gently bite and suck on her lower lip. Then her eyes drifted so quickly to the tent in my trousers, it felt like it never happened. She walked slowly, her hips swinging seductively and she lowered herself divinely onto the seat. Her legs spread wider this time and as the bus lumbered forward, she sank deeper into.
