Caught in panties in a flash

Usually Debbie would knock before entering her brother's room but the door was partly open when she came home so she just walked right in. As soon as she did she stopped dead in the door way. Gavin was lying face down on his bed wearing a pair of her thong panties and stockings fast asleep.
It wasn't just the sight of her brother in her panties that shocked Debbie but also the fact that he seemed to have waxed his body all over. From where she was standing he looked more like a girl than a boy with his smooth skin and long blonde hair. She was about to say something when she changed her mind and went to her room to get her camera instead. She quietly composed the shot and was delighted with the way Gavin woke up with a start from the flash.

He looked back over his shoulder to see his sister smirking at him camera in hand.
Gavin leaped up from the bed but in his haste he tripped and sprawled flat on the floor at Debbie's feet.
"Just what do you think you are doing wearing my panties and stockings," she demanded in a stern voice. "You've got some explaining to do."
But of course there really wasn't any explanation that he could give.
Debbie grinned as Gavin whimpered on the floor in front of her begging her not tell anyone. She could see the desperation in his eyes. She had him now, just where he always wanted him...
