When I was very young, in my early teenage, I was living in a crowded block.
The building in front of mine, in the same floor, there lived a young mother with her baby.
And there is no curtains of the windows direct to my side!
(I think they lived in the countryside before, no buildings nearby, so they thinked it is no need to hang the curtains. )
From my side , I can see through out their apartment, living room、bedroom、toilet...
In the summer, sometimes, I could see the young woman stripped in the bedroom and rushed to the toilet totally naked with the light open. Her bushes was lush, tits was nice , butt was small.
Then I bought a mini telescope.
It is so exiting to a teenage boy.
