It was seven thirty on a Friday night; my husband was where he always was at that time on Friday, down the pub. I knew I wouldn't see him until well after midnight when he would stagger in blind drunk, clump upstairs to the bedroom, undress and fall into bed. As for our thirteen-year-old son, he was too quiet, he was supposed to be up in his bedroom studying, normally there were clumps and bangs; tonight there was silence and that made me very curious. Heading upstairs I glanced at myself in the hall mirror, I wasn't unattractive for a woman of my age, forty-two, I even managed to keep most of my girlish figure and desires, but it was wasted on my husband all he seemed to want to do these days was eat, drink and sleep. Shaking my head I continued up the stairs to Dave's bedroom, outside the door I listened for a moment, the only thing I heard was silence; quietly I opened the door and looked into the room. What greeted my eyes made my heart flutter with a sudden excitement, Dave was lying naked on his bed, in one hand he had a girlie magazine, his other hand was busy rubbing up and down on his prick.

Fascinated and growing aroused I stared at his moving hand, his prick stood tall and proud, a good nine inches worth of hard flesh, I hadn't thought a thirteen-year-old boy could have such an erection and yet there it was going to waste. The magazine moved as he turned a page then got back to his wanking, watching him I gave in to the temptation to slide my hand into my panties and play with myself, I knew it was wrong, but I had gone without satisfaction for so long that I no longer cared. My eyes followed my son's moving hand as my fingers rubbed my clit and pushed into my fanny, the elastic of my panties cut into the back of my hand and in annoyance I quickly pushed the things off then got back to playing with myself. The whole situation only added to the mounting pleasure in me, Dave's hand moving slowly up and down his prick while my fingers began probing my cunt with an almost desperate haste; I knew that at any moment he may put the magazine aside and see me watching him, it only added to the thrill. A glow spread throughout me as I had a minor climax, suppressing my heavy breathing I gazed longingly at Dave's cock and something inside me seemed to snap. Retreating out into the hall I leant against the door and gasped, I couldn't get the vision of my son's prick out of my mind, nor could I push aside my growing desire to feel that same prick inside me. Everything in me told me that I should not be having such thoughts, but they just grew stronger as the minutes passed.

With a trembling hand I undid my dress and let it fall to the floor, taking off my bra I peeked once more into Dave's room, he was still lying there with his hand running over his prick and without conscious thought I stepped into his room and closed the door quietly behind me. Dave seemed to be so intent on his pleasure that he didn't notice me as I crossed the room to his bed, even when I sat on the edge of the bed he didn't react, but I had a sudden urge to take his prick in my mouth and make him cum. Leaning over I flicked my tongue across the tip of his prick, Dave gasped and the magazine dropped to the floor, licking his cap I looked at his face. At first he seemed frozen with shock, then his lips curled up in a smile as he watched my moving tongue. He moved his hand away from his prick and put it on my left boob, sighing I began to lick my way down and around his shaft, at the same time I shifted my position slightly to allow him to play with my tit more easily which he did not hesitate in doing.

As his fingers started to tease my nipple I took his prick into my mouth, Dave gave a gasp as I sucked the first two inches of his erection before sliding down on it until I could get no more in my mouth, this left a gap between my lips and his groin which I filled with my hand. The thrill I felt as I slid my mouth up and down on his hard flesh gave me another minor climax, groaning around his prick I sucked hard and was rewarded by hearing my son moan with pleasure which made me speed up the movements of my head. As the minutes passed I felt myself growing more and more aroused, the next climax I had was not so minor and still Dave had not cum, his staying power sent a surge of excitement through me that had me groaning and quivering in another orgasm. Then Dave's prick seemed to swell in my mouth, I knew what this meant and quickly pushed down on him and sucked hard with my tongue pressing just behind the cap of his prick, a moment later my mouth was filled with his hot salty seed.

"God!" I heard Dave breath as I swallowed his cum.

The flow seemed to go on forever, I sucked and licked at him happy to drink all he could give me and when I finally stooped and sat up I was both pleased and amazed to see that his prick wasn't shrinking; it was staying rock hard, ready and willing for action, action that I could not resist giving it. In a burst of motion I threw myself astride my son's body, desperate to feel his prick sliding in my cunt, I didn't give a damn whether it was right or wrong, all I wanted was to be fucked. I gasped as his cock pushed its way into me, thrusting down I took his whole length in one single motion that had me shaking in climax on top of him, his hands came up to play with my tits and my orgasm grew even more powerful. Dave grinned up at me, his young face flushed and excited as he looked at my naked body, played with my nipples and moved his prick inside me, I could not believe the power of the sensations that ran through me, even in his hay day my husband had never made me feel so abandoned.

Although I tried to move slowly so as to draw out the pleasure I was soon riding my son at a gallop, his prick thrusting deep into me, our groins meeting heavily, then sliding out almost completely before thrusting back in again. Try as I might I could not hold back my groans and cries of sheer ecstasy, all the months of doing without suddenly came together in this one blissful moment, a moment that was quickly becoming a torrent of wild sensation.

"Oh God Dave," I sobbed, "fuck me harder."

It was stupid of me to say this as I was on top and in control, with a thrust of his hips Dave suddenly rolled me over onto my side, his prick still buried deep inside me as he manoeuvred me on the bed onto my back. Then I was looking up at his face, I could see the bliss and triumph in his eyes as he began to thrust into me so hard that my body jerked each time our groins met. Faster and faster he thrust with me trying to match him unsuccessfully because of the shaking of my body, all I could do was lie there and let my son take me which I gleefully did as I locked my legs around his back. Whole galaxies of pleasure spun around me as my son drove me through one orgasm after another; Dave seemed tireless yet I longed to feel the heat of his seed shooting up into my womb. Some minutes later my wish was granted, with a thrust that made me scream with delight my son buried his cock deep inside me, I felt it swell and jerk then felt the sudden heat of his seed exploding into me in hot spurts, the sensation sent me into a wild orgasm that dimmed my senses for a time. When my senses returned Dave was moving in me again, I could not believe it, his prick was still hard, it filled my pussy and sent such messages of pleasure through me that I soared into another climax.

"OH GOD!" I screamed on a rising note, "OH GOD YES!"

I lost all track of time as my senses became overwhelmed by the pleasure my son was giving me, from screams my cries fell to whimpers and sobs as he fucked me to a frenzy, had my husband walked into the room I would not have noticed or even cared. Then Dave was pushing deep into me again, once again I felt his prick swell and jerk and the sudden heat of his seed filling me, with a scream of pure release I pushed up against him and we lay locked like this for a few seconds before Dave started moving again. Inside me I felt his prick begin to shrink and sighed both with satisfaction and disappointment, but over all was satisfaction. My son rolled off my shaking body and nearly fell off the single bed, with a gasping laugh he pushed tight to me, his arm across my chest, his head on my shoulder looking up at my face, I smiled at him then sighed as he lifted his head and kissed me.
