I can usually only fit in lunchtime punts, so it's always daylight anyway, 1 girl had a blackout curtain as her window was on the inside of an L shaped building and the neighbour would have seen right in, but she kept the big light on all the time
I was ridden cowgirl by an ex many years ago n a Spanish balcony while on holiday, lasted about 20mins with her cumming, people must have noticed as the block opposite was residential, a few old guys on the balconys reading papers
