Not public but just want to share.
Just now was watching tv in living room with gf. No one at home. She was in a spag top but long enough to cover her pussy. Nothing else. We were on the sofa and I got turn on and started to play with her boobs. Soon I was bonking her naked on the sofa. Door and window were opened but if anyone walk towards her unit, we can hear from far. After finish bonking, I was resting on sofa while gf was wearing back her spag. Suddenly I realise a guy was peeping from her corridor window and faster walk off when he saw me looking at him.
Normally no one come from that side as it was the staircase and we are the last unit. Not sure how long he been standing there but I think he stay some floors up. I think its spreading between her neighbours that here always have free show. Need to be more careful in future.....
