You’re having a nice day out at the beach. Out of the corner of your eye, you spot a teenage male that seems oddly familiar to you. When you look closer, you realize it’s your younger sister, difficult to recognize without her usual makeup and girly hair styles… and because she’s wearing only a pair of man’s swim trunks. Her chest is flat and her body lacks curves, but you can recognize her even if no one else knows she’s a girl. As you approach, you can tell she doesn’t know you recognize her.
