"Oh, my God!" panted the trembling youth, curling his fingers into her long blonde hair.He began urgently fucking his throbbing boner in and out betwe...n her moistly ovaled lips. Her mouth was so warm on his cock as her tongue swirled and teased around his sensitive prick-knob.Softly moaning as she sucked on his prick, Kim was thirstily swallowing the warm seepage that was leaking from the head of his prick. His hard cockshaft was hotly throbbing as she licked all around it.Out in the living. You dont want to stop now, do you? Youre jerking off in front of your sister and you like it. Come on, come closer to me here so I can see better. And jerk that cock. Come on, move that hand up and down your hard cock. Thats the way. Watch me pinch my nipples, you like that? I want you to put on a jerk-off show for your sister. Harder. Oh, look at all that pre-cum. Take it with your other hand and spread it over the head of your cock. Yeah, rub it in good. Keep rubbing, while you jerk your cock. After he had finished lapping up my juices we began to fuck in earnest.I sat with my legs spread wide, my stockings taut against my legs and my high heels still on. Tony pulled my arse forward to the edge of the settee cushion, and he slowly began to nudge the tip of his cock against my wet pussy lips. He then teased my cunt hole for a while, sliding his prick up and down the length of my pussy.My clit was bursting at this point, my sheer wanton lust overtaking me..."Fucking get it up me Tony!". It was the first time I had done anything like this with another man. I didn't quite know what to do, he grabbed the back of my head and proceeded to fuck my mouth. I was getting used to the taste of his cock and entered into the spirit of sucking his cock. He was moaning and eventually ejaculated down the back of my throat, it tasted salty but not unpleasant.After he had cum in my mouth I stood up and with my trousers and underwear on the spare stool my cock was rock hard. The headmaster.
