A bit about me: I'm forty-nine years old, a recent divorcee and single mum, and I live in London with my seventeen-year-old son. Between dealing with the aftermath of the divorce, and having to provide for my son by myself, things had been so hectic recently, I hadn't had an opportunity to wank in over a month. Today, though, I had my first day off in I can't remember how long, so I finally got to spend time with my son, but first, I needed to get off.

A little physical description of me: I'm a petite brunette, just over five feet, and weighing barely a hundred pounds dripping wet and raging mad. Facially, I have a prominent nose and lips, which my ex-husband, before he turned into a complete arsehole, said was my best feature.

That morning, I woke up at six o'clock, knowing my son would still be sleeping, and went to the bathroom in my silk robe, which my son had given me for my last birthday. Moments later, I was in the shower, soaping up my body, especially my small but soft and squishy breasts, getting hornier every second. Finally, one hand moved down between my legs, and I began two-fingering my hairy and extremely wet cunt. Turned on as I was, it didn't take long for me to cum. However, as I caught my breath, I realized the orgasm hadn't even remotely satisfied me, so I rinsed off, got out, then put on my robe and headed for my bedroom to engage in some serious masturbation, which I now realized might take me all morning.

On the way, I passed my son's room, from where I suddenly heard a sound, like heavy breathing. Now, I'm not daft, and I could easily figure out what the sound was, but, in my extremely aroused state, curiosity took over, and I opened my son's door a crack, and peered inside.

Now, to describe my son: In major contrast to me, Jamie is well over six feet(his father is tall, too), and heavily built, like a wing forward, though he's never been interested in rugby, or indeed any other sport. Now, I knew he was probably wanking, but figured he'd be doing it discreetly, under the sheets. Instead, I found him sprawled on the bed, uncovered and completely naked, and giving his sizable member a hard jerk. Apparently, he'd had the same idea I did.

I should've just backed away, and tried to forget what I just saw, but my libido had a better idea. After taking a second to psych myself up, I proceeded to push the door open, and pretend I walked in on him by accident.

"Jamie, have you seen..."

"Mum, what the fuck?" As he said this, he hastily grabbed a pillow and put it over his area.

"Sorry, I should've knocked."

"You think?"

I then smirked ever so subtly. "Anyway, what are you so embarrassed about? Not like I've never seen it before..."

"Not...like this..."

My smile broadened. "Well, seeing as you had the same idea I did, how about I join you?"

"I...What?"

Now full-on grinning, I slipped the robe off, and Jamie's eyes widened as my naked body was revealed to him, and I walked toward him, putting on my most seductive expression.

"Mum, this is..What?" I could tell by his breathing speeding up that he was at least somewhat game for what was about to happen. His expression was starting to grow more receptive as I climbed onto the bed, and then on top of him, before sitting on top of his pillow, through which I could feel his raging hard-on. "Mum..." Smiling at him amorously, I rubbed my hands up and down his bare chest before leaning down, grabbing his hands in mine, and giving him the most sultry tongue-kiss I've ever given. I should mention that, while Jamie inherited his father's body, he got my facial features, which made kissing my son all the more exciting, especially as he reciprocated, placing his hands on my waist, and grinding his rager against me through the pillow. This informed my next move.

Starting to move down, I kissed down his chest and stomach. Arriving at his area, I rubbed his cock through the pillow with my hand, and, smiling at him again, I whispered, "C'mon, babe. You don't need to hide this from me..." I then grabbed the pillow and tossed it aside, then wrapped my hand around his throbbing todger, and slowly stroked it. "Like I said, it's not like I've never seen this before..." I then leaned down, wrapped my full lips around my son's cock, and proceeded to suck him off.

"Oh, my God..." my son groaned, brow furrowing, then tilted his head back slowly. "Fffuuuck..." As I blew him, I could taste his pre-cum, of which there was a copious amount, briefly making me think he'd gone off early. "Oh, fuck!" Before long, he started jerking his hips, telling me he was close to climaxing, so I stopped, and sat up, again grinning at him. "God, you're bloody sexy, mum..."

"So are you, son..." I leaned down again, and we shared another sensual kiss, before I sat up again, this time working his pulsating member into my hot, tight, wet hole. "Oh, God..." my voice shook, and my face screwed up, as my son's cock filled me up completely. "Oh, my God, Jamie, your cock feels so good inside me..." I gasped, starting to slowly ride him.

"Yesss..." my son breathed, as he started to thrust into me.

"I love you so much, Jamie..." As our grinding sped up, my son's hands moved up, and he started squeezing and fondling my small breasts.

"I love you, mum..." he groaned, thrusting faster still, prompting me to speed up, too. Suddenly, another orgasm, much more intense than the last one, washed over me, causing my hips to lock up, and me to let out a loud moan, clenching my teeth.

Moments later, I was laying where my son had been, trembling and breathing hard as he ate my pussy, which by now was so wet the hair was matted to my skin. I again climaxed, letting out a long, loud groan.

Moments later still, my son knelt in front of me, teasing my cunt with the tip of his cock. Finally, he pushed it in, causing me to nearly cum again, before starting to fuck me.

As he fucked me faster and harder, I began to sweat profusely, to the point my nipples were now achingly hard from the cold air on my clammy, wet skin.

After my I-lost-count-how-many-th orgasm, almost struggling to breathe, I asked my son, "Jamie...can you...put your cock...in my arse..." Breathing hard himself, he nodded, then pulled out of me, and started to ease his cock into my butthole, dripping with a combination of sweat and pussy juice. As he worked it in, I realized I couldn't remember how long it'd been since I had a cock in my arse, and I definitely forgot how good it felt. "Ohh...God! Yes..." At this point, my body was so saturated with sweat that even my hair looked like I'd just been in the shower.

"Oh, God, Mum..." My son's voice shook.

"My arse feel good, darling?"

"Fuck, I had no idea..."

As Jamie continued fucking me, I had a couple more orgasms, even though neither him nor me were even touching my cunt. Suddenly, I felt a gurgling inside it. Now, I know I can't remember the last time this happened. As I let out a groan so loud it verged on a scream, my pussy began spraying, going for several seconds as I thoroughly soaked my son's chest and stomach.

"Oh, God! Oh, fuck!" My son then pulled out, and his cock erupted all over me, from twat to lips, which I immediately licked up, and, like me, going for a ridiculously long time. Now straight up wheezing, my son collapsed in a sweaty heap next to me. Both of us were still gasping for breath when we turned to face each other.

"Fuck..." I whispered, "That was incredible..."

"Yeah..."

"Aren't you glad I decided to join you?"

"Oh, yeah."

I grinned at this. "I love you, son."

"I love you, mum." I leaned in, and we shared one more kiss, practically sucking the air out of each other.
