My wife and I have a weekend cottage at the lake a couple of hours from our house. We always take friends with us and have a great weekend.
I have a workshop in the basement so it is not unusual for me to be down there. But, I have rigged up the bathroom heating vent so I have a great view into the bathroom from the basement. I try and time my workshop visits around when my wife's girlfriends are taking showers. One in particular (Karen) is very flat-chested and slim-hipped. I have seen her naked quite a few times. I have also watched as she shaved her pussy. One time she even lay on the floor and masturbated.
Thanks Karen (and Tina, Deb, Louise....) you have no idea how many times I have masturbated while watching you take off your bra and panties!!
