My brother and I waited in the corridor outside the Headmaster's office for our grilling. The sour faced school secretary ushered us into the office.
"Mr Lamb, "she announced, "here's the two I told you about."
"Thank you, Miss Summers, " the Headmaster replied, "I'll take this from here."
The secretary left and closed the door behind her leaving both my brother and I to our fate.
"Now Alan, Sam, there's no need to be anxious. I have had a long talk with Doctor Bard and his nurse and they have explained everything to me."
Alan and I looked at each other in shock. What had Doctor Bard told the Head? Why weren't we in deep shit like we were expecting? All became clear all too soon.
"Now then, Sam," soothed the Head as he wandered over to me and stood just behind me. He put his hands on my shoulders, to start with, and I could feel his breath on my neck. "So you've been fucking your older brother and your father."
I froze. The Head's hands slowly moved down my front and he started to gently caress my small firm breasts. My nipples started to harden as the warmth from his hands started the familiar feeling in the pit of my stomach. He continued to talk.
"Alan, does it turn you on watching someone touching your sister in this way? Watching someone touch her young firm breasts, making her nipples stiff. Does it make your cock hard, Alan?"
Alan's face was a picture. He stood mesmerised watching as the Head fondled my tits and gently pinched my nipples. It was plain that his cock was growing in his trousers. It took him a moment or two to answer.
"Yes, sir, I think it does."
"Think, boy?" Snapped the Head. "Think? It's perfectly plain that it does. Your prick is getting harder by the second. Take it out before you hurt yourself."
Alan just gorped and the Head had to repeat himself twice before Alan reacted. He slowing unzipped his trousers and fished out his stiffening rod. I found myself automatically licking my lips as his manhood came into view. The Head noticed.
"And you, Sam, do you like the look of your brother's stiff cock? I bet you'd like to rub it for him right now wouldn't you. I bet its making your little pussy all damp just thinking about it isn't it. Tell me what you'd like to do to it, Sam.
It took me a moment to find my voice. Familiar sensations were coursing through my body. "Er, well sir .."
"Come on young lady, don't be shy. You've fucked him for god's sake. No time now for being shy about it. Tell me what you'd like to do to your brother. Would you like to take his big long cock into your mouth and make it all wet with your tongue?"
"Yes sir. I would. I'd like to lick it all over and taste that bead of pre-cum from the top of his cock and swallow it down, sir."
"Good girl," applauded the Head. "Now, just thinking about it. Is it making your pussy wet?"
"Yes sir, very wet." I was getting into this. I was getting very turned on by this cat and mouse sex talk. Alan was too if his straining cock was anything to go by. "In fact, sir, my cunt juices are soaking into my panties right now."
"Hmmm, is that so," the Head half whispered from behind me, "let me see."
He moved his right hand down my body until he was gently stroking my thigh. Then he moved his hand up under my short skirt and traced his finger along my oozing slit through my panties making me gasp out loud. Next he moved his hand to the top of my panties and slipped it down the waistband. His fingers continued their journey finding my smooth, wet slit and pulling my cunt lips open. He explored inside my lips flicking my clit a couple of times before seeking out my pussy hole and slipping his finger deep inside.
