I ran a palm over the smooth flesh before bringing it down hard. She yelped, not expecting it. I gave her another good spank, this time on the other c...eek. Another muffled scream shot out. I spanked her a few more times until the flesh was red, and my hand was imprinted on it. She had been reduced to whimpers, and I decided to quit teasing. I placed my cock between her wondrous pink folds, and penetrated her pussy. She moaned with relief at finally getting what she had wanted. I soon got up to. For you see Mr Smith is magnificently well endowed,as have many girls found out. His cock is a good twelve inches, and beer can thick. The head looks like the proverbial sheep's heart.When it was time for Gilly to come in the two prefects had to drag her bodily through the doors and up to the cocking bench.She was trembling from head to foot as they left her. Mr Smith had disrobed by this point, and was wanking off his cock to get it properly hard. He made sure the prefects good a good. The penis he mentioned immediately responded and rose to full mast in an instant. "I can see your prick is excited," my father stated as he pointed at the tent in my pajamas."I am going to give you a blowjob, Scott. You're old enough now to experience the pleasure of lips on your penis."I was speechless as I stared at my father with bulging eyes. I would never have thought that he would utter such lewd words, let alone try to get into my pants. But I was f******n and horny as hell and wasn't. I stopped breathing when he held my butt cheeks open and I could feel his eyes intensely staring at my puckered pink butt hole. The sound of a sharp deep intake of air was heard from me as his warm wet tongue slid up the length of my butt crack and his tongue found and swirled in little probing circles around my pooper. He was working his tongue into my butt , my low sighing moans reached his ears and he probed deeper with his tongue. I began moving my hips and pushing them up and back. I began.
