Back in the bedroom, after an exciting time in the bathroom, my arse still wet from the slurping of mum and dad's tongues deep inside my hole, the threesome with my parents that had begun when my dad Keith caught me sniffing my mum Susan's panties, was now about to take on a new and more hardcore dimension. Mum laid back on the bed again and once more spread her legs to show off her pussy, nice and clean and delectably fresh-smelling after the recent shower.
"She wants it licked again, son," my father said, giving me a quick kiss on the lips, "now that you know what to do, go and thank her for licking your arse and for being such a good mother."
"Sure dad," I replied, only too eager to taste mum's moist pussy again, "and I'd like to thank you for rimming me, too."
"That can be arranged, son," dad said, "but see to your mum first. She's gagging for it."
"I can see that, dad," I said, glancing at mum who was spreading her legs wide on the bed, her glorious pussy fully exposed to mine and dad's admiring eyes, "and I can't wait to fuck her."
"You will, mate," said dad in his usual friendly way, "she ain't gonna deny you that pleasure, are you, honey?" he added, smiling at his wife.
"Certainly not," said mum, a determined tone to her voice, "it's all part of your education, sweetheart, but I need my pussy licked again first. Come here, you sexy sod, and give me that talented tongue of yours again."
"Go on, Scott," dad said, twerling his impressive cock in his hand, "don't keep her waiting. Prove to her just what a sexy sod you are."
"I'll do my best, dad," I replied, giggling since it was only a short while ago I had licked mum out and, furthermore, shot a nice big load of my hot sperm all over her, to her full approval and great delight, I might add. And dad's too, my father having shown himself to be a very enthusiastic voyeur as I unleashed a torrent of cream that was right up there with those I had seen delivered by the male actors in my mate Brian's porno movies.
It had been the first time I had ever covered anybody with my long ropes of spunk and the fact it was my mother on the receiving end made it all the more exciting. Much better than wanking off on your own and cumming over yourself though I daresay I shall continue to have the occasioal solitary wank, not to mention those with my mate Brian during our once or twice a week mutual masturbation sessions.
Now, however, I was rapidly discovering that both my parents were sluts of the highest order and that I was happily following in their footsteps, all of us as hungry for sex as often as we could get it.
My enthusiasm was the same when I wanked with Brian when we watched his porno movies round his place; I would go off for a bit after cumming but as soon as Brian put another movie on, me and my proud cock were raring to go again as, of course, was Brian's. Thus it didn't surprise me in the least that mum and dad were horny again so quickly after our shower.
So, not wasting anymore time, I knelt before mum and gazed lovingly on my birthplace, wondering how many other sons get to enjoy the privelege of making love to such a sacred hole. My mouth drooled saliva as I reached out to fondle the strands of pussy skin and pubic hair with my touchy feely hands as mum spread her legs even wider to highlight her juicy hole to the best advantage while dad wanked his cock a little harder.
"Lick me, sweetheart," mum implored, "my pussy really needs another good going over. As your dad said, don't keep me waiting."
"Yeah, go on Scott," dad said, "get stuck in there and enjoy yourself, that's what we're here for, to enjoy the sheer pleasure that our bodies give us."
I leaned in closer to mum's exquisite cunt with my tongue at the ready, breathing in its intoxicating aroma that, up until this glorious day, I had secretly only been able to enjoy from her scent left behind on her used panties. I wasn't going to give up sniffing mum's panties for good, of course - indeed, I could now do so in front of my parents and not behind their backs as had been the case until now - but the real thing was so much better and I ran my tongue hungrily up and down the gash, lapping her juices onto my tongue before finding mum's awesome-looking clit and smothering the hard nub with lots of loving little kisses.
"Good boy," mum said, with a strong undertone of lust in her voice, not wanting me to stop and placing her hands on my head to hold me there as if fearful I would pull away, "oh, honey," she went on to my father, "our Scott is so good at this. He truly is a really loving son."
"Sure fucking is," dad agreed, again happy to play the role of voyeur for now as I parted mum's labia with my hands and sent my tongue in as deep as I could to give her - and me - maximum pleasure, "no parents could wish for one better."
I smiled up at mum as dad moved round and stood next to me so that his hard cock nudged against the side of my face. I could tell what he wanted and I found myself in a dilemma, should I go on pleasuring mum since she was enjoying my tongue so much - as I was enjoying her cunt - or should I transfer my attention and suck my father's cock?
Mum answered the question for me a few minutes later as she gently pushed my head away. "That was divine, sweetheart," she said, as she manouevred herself until she was squatting on the bed with her legs folded under her, her big tits dancing merrily beneath her neck, the nipples erect, "your dad and I have looked forward to this day so much. Now let me see how good you are at sucking cock."
Before either dad or I could say anything, mum reached out and grabbed dad's cock in her hand and pointed it towards my mouth. The big head was fully exposed since dad had his foreskin peeled right back and the glossy pink knob glowed and throbbed with life, the little beads of pre-cum evident as they oozed from dad's pee hole.
I gave a few tugs on my own cock, which had remained rock hard ever since mum and dad had rimmed me in the shower, and opened my mouth in obedience to mum's command. Then I swallowed my father's aroused prick in one long gulp, my head going backwards and forwards as I treated him to his first ever incestuous blowjob.
"Now you can thank your dad for rimming you like you thanked me," mum said, leaning in as close as possible to get the best possible view in full glorious close-up, taking over the role of voyeur from dad. I was champing at dad's cock, hoping I was thanking him sufficiently for his expert licking of my arsehole while mum flashed her sunshine smile at me again, delighted to see me so enjoying myself.
"Fuck, son," dad said, glancing down at me to watch his cock drilling in and out of my inexperienced but hungry mouth, "you sure know how to thank a man. Are you sure you haven't sucked cock before?"
