#34529 - As always when you visit family there's always an element of disruption and on this occasion we were told to stay in Katie's room and she would sleep in the single bedroom which was ok with everybody. First of all let me introduce myself I'm mark 35 years old just a normal guy this incident happened 2 years ago, my wife Susie and i travelled to the south of Spain to visit her mother and father who now live and work there, also there was my wife's younger sister Katie she had just turned seventeen she's about 5'3 slim figured with raven black hair and an ass to die for I know your not meant to look at your wife's younger sister like that but I'm an ass man and its just perfect as much as you could guess at by looking at her in a bikini by the pool. Later in the afternoon we were all lounging by the pool having a beer and of course I was having a look at Katie in her swim wear as well as my mother in law who still looked stunning for her age, afte
