Daughter’s Friend

My daughter’s best friend was taking a 4 month course in order to be certified and needed a place to stay here in town. Of course I said she’s free to stay here. She’s a beautiful woman 34 years of age. I’m a man at the time , 59 years of age, divorced, in great shape mind you, but never dreamed that what happened, would. In our first day, Sara took to skinny dipping in my pool. She asked before hand if that was okay with me saying, fine. I myself do the same but never with people around. This kept happening almost every day when weather permitted. Morning coffee, she would walk into the kitchen thinking nothing of being topless. Many times while sunning herself in the nude, walking into my bar area and pouring a drink, chatting away as if this was a normal thing. The fifth week of her stay, one night she asked if she could join me in my hot tub that night which is off the master bedroom surrounded with a privacy wall. Of course! And of course we were both nude. Never a pass towards me. Never any sexual suggestions. One such night in the hot tub she pranced in standing before me and asked how I liked her new look, that of a clean shaved pussy. I said I liked it but I liked a muff as well. She laughed and crawled into the tub. Finally one night, while I was fast asleep in bed, she knocked on my bedroom door. I said, yes? She walked in crawled into my bed and said “I need a good fucking.” And we did just that and did a lot more of it the remaining time she stayed with me. That was a year ago. We haven’t been in contact until a few days ago. She says she’s coming into town and asked if she could stay with me a couple of days. Now how could I say no?
