Sadie raised her hand to cover her mouth, contorted her face and screwed up her eyebrows to reveal her shock and disgust. Then she placed a hand on her tilted hip and clasped the door handle with the other.
"What the fuck do you think you're doing with my underwear?" she inclined her head to the side.
Chris tried to pull up his shorts whilst still turned on his front.
"Umm, it's nothing," he said. There wasn't anything else he could say. Sadie's panties lay in full view of both siblings and denying they were hers would be pointless.
"It doesn't look like 'nothing' to me," she said. "Were you jerking off in them, you sick fuck?"
"No I wasn't, I promise," of course his intention was to wrap the soft delicate lace around his throbbing cock at a some later point.
Sadie stepped into the room, bent over and picked up her panties between her thumb and forefinger, turned and made for the door. Just before walking out the door she turned her head and smiled, a dry grin.
"Let's hear what mom has to say about this when she gets back from work?"
"No please don't Sadie. Please, please, please don't. I beg you."
"Clean yourself up you sick disgusting pervert."
She left the door open and walked quickly down the hallway.
This had all happened so quickly that he could still feel the warmth of blood that had rushed to his face, or was that the rush of blood from being completely humiliated. His dick lay against his groin, limp now from shame and guilt.
'How could I be so stupid?' he rebuked himself. 'What was I thinking?' he got up, slammed his door shut and resolved himself to spending the remainder of the day in his bedroom. There was no way now that he could possibly face Sadie. He decided to put the incident to the back of his mind and draw some non-sexualised animated figures. Drawing was his happy place, where he could slip into that safe corner of his mind and forget the world around him, which is what he needed a this moment. Every now and then he would scold himself when the memory of the incident illumined itself in his mind's searchlight. 'I'm sure I'm not the only guy to ever have done this,' he reasoned with his conscience. 'Maybe I am though. I've never heard of anyone doing this before, but then it's not the kind of thing you would generally hear someone talk about., is it?'
He put it to the back of his mind and busied himself for the remainder of the day, until he heard the sound of footsteps coming down the hallway followed by a knock on the door.
"Chris, it was his mother's voice. Is that the time already? He looked at his watch, four thirty pm.
"Are you settled in son? She called from the other side of the door. He loved that his mother respected his privacy, unlike Sadie who just barged in. 'Hmm. I can use that in my defence,' he grinned to himself. He stood up to open the door, stuck his head through the gap and smiled at Tessa.
"Yeah mom, it's actually not bad at all."
She sighed in relief.
"I'm so glad Chris, I felt awful today thinking about you having to give up your kingdom for Sadie. Are you sure you're okay?"
