I am not related in any way to the family, but have always been known as Uncle Bill. At 35 I had lost my wife four years earlier and was finding it hard to develop new sexual relationships. The trip the family and I had gone on, to Scotland involved a huge house that easily accommodated my friends Pat and Bert and their two children and their partners. We spent the day walking and swimming in the sea and the evenings eating and drinking.
Jenny was the youngest at 18. Her boyfriend (Fred) who was 19 seemed very immature but they seemed to get on well and often managed to sneak off, I presumed to have sex. Jenny was lively and pretty with a stunning if still developing body. She was slightly over-weight but seemed firm and fit with it. She often teased me about being old and passed it, but enjoyed flaunting her body in an outrageous way somehow managing to keep it fun.
On the penultimate night we had the usual drinking session. Jenny's boyfriend Fred drank heavily and retired first. Even though they were obviously sleeping together they at least theoretically slept in separate rooms. Jenny had been drinking but did not appear drunk. After joining in one particularly silly game I retired to my room. I had only been there for five minutes when the door opened and I heard Jenny's voice say.
"Oh God Fred I hope you are up for fucking me silly. I am randier than I can remember. Uncle Bill has got to be the sexiest man I have ever met."
I don't know why I didn't stop her there and then, but I didn't. With the door shut there was no light in the room. I strained my eyes to try and see her as she undressed only a yard away from me. I couldn't make anything out but decided it was sensible to turn away and pretend to be asleep. I had seen nothing but my prick had imagined plenty. I nearly said something as she snuggled up behind me and reached round and found my erection.
"Oh Fred I have never felt you harder or as big."
Her hand was warm but felt very small and gentle as she stroked me. She made appreciating noises in my ear as she did so. I was panicking and did not feel I could take control of the situation. I need not have worried as Jenny turned me onto my back and knelt over me facing my feet. Her bottom was less than a foot from my face but I was gutted that I could only just make out the outline but could not see the detail.
I could however smell her presence. The aroma was strong and I have to say not the freshest I had ever experienced. For a few seconds it worried me that it would kill my excitement but suddenly it did the opposite and I buried my face in the wettest pussy and anus I can recall. My prick was buried in a very warm wet mouth at the same time. I adjusted my position so my mouth found an erect little clit. This was met by a moan that vibrated through my prick. With my tongue finding her clit my nose found the center of her anus.
