Mrs McDonald passed Sally another tissue saying she should dry her tears. Sally did not know whether to get up or stay down but her quandary was resol...ed quickly as the headmistress announced, “You have accumulated twelve penalties, girl, so present yourself to my secretary this afternoon at four o’clock sharp for those penalties. After that, I sincerely hope you will never again be late for school.”Saying so, she stored her cane away. Ann helped Sally into her knickers and dress and led her to. My sister started searching for her cupboard for the dress, to be worn, the next day. I wished to see what outfit she is going to select. But since I need to get up early, I ignored it and went to bed.The next morning, I woke up and prepared myself for the tit feast going to happen in a few minutes. My sister is in a red churidar top. She has a bag for her gym outfit. Then we both went to the Gym center. There, they were eagerly waiting for my sister. They are already in their workout session. " Owwwwwwww that hurts so much.....please stop!' she squealed."You must do as we say Catherine, let anyone man or woman do anything to you. You are our sex slave, our cock whore and cum slut!" she said in a stern voice do you understand?" Yes, yes please don't whip me anymore I'll do what you want!" Catherine begged. "You will also be trying some new sex acts Catherine. You will be licking and sucking pussy today. Whoever wants your mouth on their cunt you will do it!! Tell me you want to lick. With a mischievous grin on their faces, they gave me a quick flash and raced off into my sister's room. I stared in their direction for a few minutes, turned round and put on the television. The rain had not slowed down, and it was too cold and wet to go outside. Not that it really mattered. I was enjoying watching television in front of a nice, toasty fire. Hours passed. I drifted in and out of sleep in front of the fire. After a while, I dozily woke up out of a snooze and my eyes.
