Description
Every year during Summer our family gets together at our's parents lake house for a week or so. It's me, my parents, my older sister with her kids and husband and some family friends. This year my sister was feeling really horny, I guess her husband didn't have time for her needs. Every time we were alone she always talked about the "sexperiments" we had when we were younger, and that made me wanting her again. One morning, while all the family was at the lake, she was showering outdoor and I simply couldn't resist.
