It was a Sunday morning, one of the few days when we were actually all home together. I'd gone down stairs to the laundry room to wash some dirty clot...es of mine, discovering that the girls had left some of their laundry sitting in the dryer. I was used to doing Christy's laundry from time to time, as it was easier and more cost effective to add some of her things to mine. But as I pulled out several bras, and the skimpy kind of panties I'd never seen Christy wear before, I felt a little weird. Indeed, as I heard the door open and her first footsteps approaching, I deliberately and wilfully polished the tip that bit harder to make absolutely sure she was in no doubt of my disobedience. I continued to polish it as she stood before me in an air of complete contempt idly running her fingers along the shaft of a thick leather strap similar to the one we used to receive at school. "Come with me" she barked assertively. As I hesitated those same words were stridently. I wished I was somewhere more private so I could whip it out and masturbate to relieve the pressure.Suddenly a hand grabbed my notebook and pulled it off my desk. I looked up to find that Ms. Pearson had come up behind me curious as to what I was doing. "See me after school Mr. Dorsey. I will hold on to your notebook until then."Fuck! I was caught! I wondered how long I would have to stay after school. I wanted to jerk off badly but it didn't look good for me right about then.After my last. After a short while I could hear a soft slapping noise and I knew that they were doing what I had been caught doing. I looked over my shoulder to see and was shocked to see that they were rubbing each others cocks! They shouted at me to turn away and to take down my pants. They were now looking at my bare bum and I could hear some feint groans from them. I remember at this point not being too frightened anymore and felt a strange sort of pride that they were enjoying the sight of my bum cheeks..
