[Coolio69]

I have seen my wife’s younger sisters tits, and more...., when she was about 19 or 20, many years ago. We had only been married about five years and she often used to come and stay the odd night at our house to help my wife with our very young children . It was only a small house and so she would sleep downstairs on the sofa. My wife would go to bed for some much needed sleep and I would follow her up about an hour or so later leaving her sister downstairs to get ready for bed.
However, unbeknown to her sister I did not go straight upstairs to bed but I would very quietly sneak outside in to the back garden and up to the window of the room she was in. No one knew but earlier in the evening when it was going dark we would close the curtains but I would make sure that there was a small gap where the curtains met and rested on the window ledge thus giving me a spy hole in to the room where she was to sleep.
After I left the room she would make up her bed on the sofa and then nip to the downstairs loo before coming back, making sure the door was shut tight and then get ready for bed. She would lay her nighty on the sofa and then start to undress. Nothing sexy of course as she had no idea that anyone was watching her every move, as she stripped completely naked right there in my lounge before putting her nighty on, turning the light off and getting in to bed this ending the show.
This was well before she had her own kids and her young tits were very pert, not as big as my wife’s but very very nice with small pink nipples and she had blond hair on her pussy just Like her sister before she started shaving it off..
The highlight of these experiences that I will never forget was on the times that I saw her playing with herself before she put her nighty on. She would sit on the edge of the sofa naked (in my lounge!!) and would finger herself while facing the window with me feasting on her innocent unaware nubile body. I will never forget seeing her laid back with her legs wide apart showing her pink pussy while strumming her clit just a few meters in front of me. As our garden was surrounded by high bushes I would take the opportunity to have a crafty wank while watching her. It would never take her long to bring herself off but I would always cum first and splash hot spunk over brickwork below the window. She would then get up put on her nighty and turn the room light off, at which I would very carefully and quietly re-enter the house and sneak upstairs to bed.

Happy days!!!!
