The music picks up tempo and so does the speed of our bodies, fucking. At one point he slows down and takes his cock all the way out before sliding it...in hard, letting me feel the contrast between having him inside me. He stops moving his hips and forces me to fuck his cock, backing myself onto him, using his cock as my personal fuck stick. Letting me do what I want with it. This turns me on so much that the walls of my pussy start to contract and I can feel myself getting close to orgasm. He. "Hello Gordon," he weakly responded."Heh listen to him, Hello Gordon," Andy quipped.I slipped off the wall and moved a little closer to the action. Gordycontinued, "You see Professor, my girl Lesley here tells me that you gother into some trouble the other week," he edged a little closer to him."No I didn't." Oh so now you're calling her a liar now," his tone rising."No not really." Well what is it then she's either lying, or you are, what am I tobelieve, the girl I am seeing, or a little. It all went into the diary on my computer, including allof the questions that arose from my realisation.For the next couple of weeks, everything was OK, I was back into school andmy friends, none of which I had any sexual feelings for, but took greatenjoyment in stealing fleeting glances at during time of nakedness orsemi-nakedness. I pretty much continued to bumble along - until one ofMum's trips away.Mum was actually going away for two nights on this one trip - over a weekendthough - up into. I could feel it and i knew he would cum soon. He picked his pace up and i couldn’t help but gag loudly as he truly started to fuck his sisters slut throat. He was going nearly balls deep now that he had control and I’d never deepthroated a dick this big before. He gasped and shoved his cock all the way down my throat holding my head still with his hands, refusing to let me up for air. I felt his cock throb as he came, his cum pouring down my throat, forcing me to swallow or drown. I swallowed.
