Everything seemed so different that first day, like someone had shuffled all the fuses in my brain. They still all worked, but now the patterns of my thoughts were very, very different. Like the native American Indians, I seemed to have lost a thousand reservations, but unlike them I had gained a million new lands. I could look at the world now and see endless opportunities for all the weird and wild things that I had only ever dreamed about before, and I could see countless ways that I could help shape my sons life. Roughly translated, I was suddenly seeing a thousand ways we could have sex together.
Our first night had been an eye-opening (and leg-opening) delight, and the new day had started in just the same way. I couldn't deny that I wasn't surprised when the transition from a normal mother and son relationship to this new taboo fuck-fest partnership had proved to be more than just a physical thing, but the depth of emotion - okay, love - we seemed to feel for each other was breath-taking.
That first full day had already seen us copulate twice despite the soreness evident in my under-utilised pussy, and there could easily have been a third, fourth and who knows how many more fucks if the soreness really hadn't become almost insistent.
In any case, we needed to replenish the contents of the fridge - especially as we both seemed to be developing an appetite that was spurred on by the sexual desires we were both experiencing - so we'd set off for a supermarket run, and somehow managed to keep our hands off each other long enough to fill one shopping trolley. Result.
Matthew was impeccably behaved, even when I asked him to help me carry all the bags inside when we got home, and even more wonderfully helpful when he didn't hesitate to help me store all of the purchases away in the fridge and the larder. I nearly wrote a letter to the Queen asking her to award him her highest medal of honour when he didn't even complain - too much - when I refused his advances that evening. At least, he didn't after I explained how his lovely hard cock had turned my already sensitive pussy into something that felt as if it had been skinned, grated and then dipped in salt.
I must admit that any complaints he might have had soon disappeared when the desire - the need - to keep my new lover satisfied got too much for me to resist, and I broke a fervent kiss in the living room when I dropped to my knees and pulled his shorts down.
"So," I asked, grasping his hard cock, "Have you ever had this lovely, smooth sword kissed and sucked?"
"Oh, ma, no, never. You mean you'll-"
I interrupted him by flicking my tongue across the tip of his erect cock, the taste of pre-cum already present, "You're going to have to get used to it," I grinned up at him, "if we're going to stay lovers for a couple of months."
His brow wrinkled, "I don't understand."
I couldn't resist but open my mouth wider, taking the head of his member into its warm depths for a few seconds before saying, "You have a lot to learn, but don't fret. I love being your teacher, and the lesson here is that some days, even when I'm not as sore as I am now, we won't be able to have full-on sex because I'll be menstruating, got it?" I took the head of his cock back into my mouth, looking up at him to see his reaction. Even if he was suddenly squeamish it didn't reduce his hardness any, and his hips began to sway backwards and forwards.
"Oh... fuck that's good, ma... you're talking about your... period?"
I nodded and started to swirl my tongue around his shaft.
"I wouldn't care," he was already gasping, but I sensed there was a control building within him now and I didn't ease off.
I paused, but didn't feel like releasing him even for as long as it took to answer, talking instead around his cock I said, "I would for a couple of days. But we can do this instead."
"I can't believe I'm in your mouth, ma. I love it so much."
"Is this perfect for you, Matty," I managed, barely pausing this time, "Perfect with your hard cock in my mouth?"
"Oh, yes! I love it, I love it!"
My free hand pulled apart the top of my dress, my bra-less breasts exposed then, displayed for my son's pleasure, "Hold my head and fuck my mouth all you want."
Both is his hands tangled in my hair then and his movements become more pronounced, the depth of his thrusts intensifying even as he started to pause with each near-withdrawal so that he could stare down at my tits. "Gorgeous Bristols," he managed.
I lost the pattern of my rhythm as I snorted a laugh, pausing then to pull my head back for a moment "Bristols?"
"Bristol Cities," he was remarkably relaxed still, "Rhyming slang."
"Oh you mean titties?"
"Yeah but please starting sucking me off again."
I licked the tip of his cock, making him moan, "You should be more polite if you're gonna use slang like that."
"Like how? But please suck me, ma please!"
"Bristol and West - chest - that's much more polite. Still rhymes." I opened wide again and he almost choked me as he rammed forward.
"Yes!" He started to fuck my mouth again, his grip now firmer in my hair, "That'd still be Bristols and... fuck, yes... and your Bristols, your tits are perfect!"
I cupped his heavy balls then and started to really work my head backwards and forwards, not quite deep-throating him but feeling him in the very back of my mouth each time he thrust and my head bobbed forward.
Matthew was panting heavily, his excitement evident in every one of those ramming moves, and his fingers were rhythmically tightening and twisting in my hair. His heightened - and ever heightening - level of arousal was contagious and although I felt a deep need to explore the wetness that was now pulsing deep within my womanhood, the soreness kept my hands working my boy's cock as I sucked and licked and kissed it. Instead I found myself tightening and releasing my pelvic muscles, rocking my own hips as I knelt there with my son's hips positively vibrating with every thrust.
As seconds of sucking and licking became minutes, our mutual arousal continued to rise and became somehow, more of a single, shared, entity. I love to suck cock sometimes and I know it's often appreciated far more than the act would normally be - I'm really, genuinely, good at it, in other words - so when Matthew kept the act going for so long I knew that this was more a case of his control already becoming greater than anything to do with his lack of real enjoyment. He was prolonging his pleasure and at the same time, driving both of us towards the stars.
I licked the entire length of his rigid cock, sucking hard and then softly, took more and more of its length into my mouth, encouraged his pulling at my hair and head with grunts and moans of fervent approval. Our mutual delight became something that was almost frantic, the entire thing being a face-fuck of epic proportions. My boy's pubic hairs were grinding into my jaw with every thrust and each time the head of that hot, hard cock pressed against the back of my throat, my pussy, sore or not, pulsed with orgasmic delight.
My ears were ringing by then, but I heard Matthew start to moan 'oh, ma!' over and over. His movements started to become jerky, ragged, and yet faster and harder. His hands were now entangled in my hair and pulling my head hard onto his cock as he pounded it as hard as he could into my eager mouth. I would have objected to that at any time in my past but now it was just perfect, just right, and when I realised that he was on the verge of erupting into my throat, I grabbed his butt cheeks, determined not to let a single drop out of my mouth.
And then it happened. Matthew thrust as hard as he'd ever done before, wailing 'yes!' at the top of his voice. His cum exploded from his cock, spurting hard and straight down my throat, and I sucked greedily, welcoming it, eager for it, drinking it. He pulsed again and gave another push just as I started a climax of my own, and I felt the head of his glorious member penetrate even further. I didn't, couldn't - never wanted to - stop it, and even as he cum in his mother's mouth for the first time, I experienced a first of my own, deep-throating for real.
Somehow, some way, I didn't choke or gag, and continued to suck every last drop of his cum down into my belly, holding him tight to my face.
