My friend's older sister is a gravure idol who won the Grand Prix from a certain newspaper! (Also, she does some pretty naughty things.) When I went to a friend's house to see her older sister... her senses seemed to be a little different from those of normal people... she didn't mind being naked, and wore racy swimsuits and underwear. She wanders around the room and shows glimpses and flashes of her I cup breasts! When I saw that, I got an erection.
