Idea was simple: Sexigrajka is blindfolded before our guest comes and until he will go. She will see who fucked her later from video. My part was to choose guest. She was sure that this will be someone who we already meet, but I choose cashier from our local grocery shop, who always stare at her. Even when he said "lucky guy", she only recognised that she knows his voice but was unable to find who he is. Of course, like always, everyone had good fun :)
