Spying,,,

When i was younger i would stay with my Aunt & Uncle for weekends i had 2 cousin's Mark & Jane we got on really well spending time playing games and watching TV, my Uncle did Motor Racing as a hobby so on Sunday we would all go to the race track and watch him, I would stay over Saturday and go home on Sunday evening if it was a bank holiday i would stay Sunday night as well.
One Saturday night i woke to hear some noise;s i never heard before o got up and opened the bedroom door { i was in the spare room } i could hear what sounded like moaning coming from my down stair's i crept down i could see my Uncle fucking my Aunt on the sofa they were in the missionary position my Aunts legs were wide open and up in the air while my Uncle was pounding her as i watched i felt my cock getting hard and the longer i watched the harder i got i found myself taking my cock out and wanking , after a while my Uncle pulled and shot his load over my Aunts tummy when i saw this i also cum shooting my load on the carpet i quickly went back to bed, They were great Weekends,
