I don't normally return to a story but I've had so many requests for a finale to this story that I just had to provide a final chapter. Inevitably I can't include everyone's requests and desires in the story but I hope you'll all be fairly pleased with my efforts.

After our wonderfully sexy, highly exciting, very tiring day out we'd returned home to face the music - only to be completely shocked by our darling mother, a mother who, it seemed, had enjoyed much of the same activity with her brothers too - brothers who had actually fathered both my sister and I.
Instead of the dressing down we'd more or less expected our activities had been almost entirely condoned and then, instead of a kiss goodnight, Mum had sucked me off most enthusiastically.
We retired to bed, well, to my sister's bed, in a far more happy state of mind than we'd anticipated and had even managed a final if somewhat exhausted fuck before we slept.

I woke early, stirred by memories of my alarm clock or unaccustomed perhaps to finding myself in a strange room and turned gently, rolling onto my back as I enjoyed the softness of the bedclothes against my naked body. The scent of my sister's body flowed through my nasal passages as I turned and pressed my face into her soft pillow and then my stretching hand met another body beside me. I let my fingers roam, stroking the warm softness of my sister's flank and then the slightly cooler and more pliable flesh of her breast.
My equally naked sister was right there beside me and as I roused into full wakefulness I immediately remembered the warm and sexy reception that Mum had given us last night, followed by the gentle love-making that had followed once my sister and I were in bed. As the memory rose in my brain it seemed that my cock jerked into rigid stiffness at the same instant - an entirely different hard-on to that produced by pressure in my bladder. I pushed myself into a sitting position as I ruminated on our home-coming last night and considered what to do next.
Mum, my actual, real, no-nonsense Mother had sucked me off, succeeding in drawing from me a generous mouthful of cum despite far too many eruptions during the course of my day out with my sister. And then of all things, she'd compared my erection with my uncles, my gruff, clean-living, law-abiding uncles - uncles who had produced both my sister and I. On top of that she then explained that our Dad-as-we-knew-him was aware of our activities; would be updated once he woke up and wasn't our real dad either - and that he also condoned our activities too!
As I felt my cock stiffen with pride and eagerness as I shook my head in amazement and then I glanced at my sister Sharon once again, noting now that by sitting up I'd pulled the bedclothes from her upper body, exposing her delightfully pert and generous tits. For a short while I just admired them, their perfectly smooth skin, their gentle softness, and their deliciously firm little nipples. I thought back to the way they'd bounced and shaken as she'd ridden me and the way they'd felt so delicious against my chest, or between my lips, for that matter.
I felt another tremor slide up the length of my cock, then realising that I did actually need to release the morning pressure on my bladder I covered her up again, dragged my eyes away and edged quietly and carefully from the bed.
Silently I padded across her room, opened her door, checked that all was quiet, closed it behind me and tiptoed across the landing to the bathroom, my persistent erection leading the way, his hardness only vaguely daunted by the prospect of meeting either of our parents as they left their bedroom. There were no sounds to be heard however, so I quietly opened the bathroom door and slid inside, pirouetting on the balls of my toes as I did so to look back to ensure than no-one had seen me and in the process I now backed into the bathroom only to be shocked out of my skin.
"Boo!" said Mum's voice behind me and there she was, sitting naked and silent on the toilet.
"Ahhh Mum!" I gasped, as I jumped and spun around, entirely uncertain how to address one's mother when both of us were naked, "What on earth..? Oh I'm so sorry!"
"Haha, this is fun! Pardon me, perhaps I should have locked the door," she said politely but with a chuckle, "Sorry darling, I just had a wee and I was thinking about what I had to do today, just sitting here minding my own business when you crept in."
"It's alright, I'll go," I spluttered feeling my erection fading quickly, but Mum calmed me quickly.
"No darling, you stay, I've just about finished anyway - I guess you need a wee too or perhaps you need something else?" she said, her voice turning warm and sexy, "So what's most important this morning?"
"I umm, need a wee, that's most important," I said, "Then some breakfast I think."
But as I spoke my cock betrayed me and in just a few seconds my cock had stiffened once again as the sight of my mother's naked body and the memories of her sexy mouth arose.
"Sorry about this thing," I muttered, "It's ummm, a bit out of control, I think."
I glanced down at my erection, an erection that showed no signs of flagging but Mum merely smiled happily, wiped herself, arose from her seat and advanced towards me.
"What's to be sorry about - that's a most excellent cock, darling," she said as she stretched out one hand and encircled my shaft with it, "As I found out last night."
"Ohhhh!" I gasped as her warm hand slid over my instrument, "No, no Mum!"
"What's the matter darling - too much for you am I?" crooned Mum as she explored my penis, "Come on darling, let me get to know this lovely thing better."
Are you sure this is ok?" I gasped as she stroked me, "I mean what about Dad - won't he...?"
"Of course he won't," answered Mum seeing the problem from an entirely different angle to me, "I'm sure he'll be really proud of you, that's a really excellent erection!"
"No, no - I mean won't he get annoyed or anything?" I asked urgently but Mum shook her head.
"Don't be silly darling, just the opposite!" said Mum calmly, "He's having a bit of a lie-in now, it being Saturday but I brought him up to date last night, so he knows everything that went on and it got him going nicely, I might add."
"Honestly?" I breathed in amazement and Mum nodded energetically, then she moved closer still, bringing her hands up to surround me.
She pulled us close together and let her nipples slide and press against my side so I could feel their hardness on my skin and also now the wiriness of her pubes as they rubbed against my hip and then against the underside of my cock as she squashed it between us.
Mum was quite a beauty actually with a pretty face and soft wavy light brown hair that fell to her shoulders. She was some six inches shorter than me but packed lots into her smaller frame; her lovely face; her wonderfully swelling hips, her narrow waist and her magnificent tits being her outstanding attributes.
Before this weekend I'd only seen glimpses of her naked in any way - I'd spotted her entirely exposed boobs one day as she was changing, I'd seen her absolutely peachy little arse on several occasions but her prettily trimmed pussy was a new sighting for me and my cock had become suitably excited, but it was her breasts and her firm nipples that were stirring me right now.
"Actually he suggested that the thought of you and your sister together and of course your sexy story might well perk up his sex drive," she said as she languidly rubbed herself against me, "Well, it certainly did this last night! And mine for that matter!"
Mum laughed happily, a sound that echoed brightly around the bathroom.
"And I'll tell you what," she said as she moved, sliding her hand down her belly, "He was harder than he's been for ages and he gave me another lovely ride this morning! Look, I'm still oozing his cum!"
She spread her legs apart and held the lips of her pussy wide and then giggled as a little trickle of cum fell from her pussy onto the floor.
"Oooops," she said as she closed her pussy and her legs, then stretched to grab some toilet paper which she used to wipe the floor, "See, he's still got it even if he doesn't make as much spunk as you do."
A moment or two later my cock surged as Mum grasped my shaft and then tweaked the underside of my knob and she breathed in deeply.
"Oh just look at you!" she said with a sigh as she pushed us apart, "All that lovely precum - I bet that's delicious!"
She began to bend down but I held her from going any lower and backed away a bit.
"It won't just be precum you'll get, it'll be pee if you don't let me go soon," I said, "It's getting a bit urgent."
"Oh Chris I'm so sorry, I totally forgot about that," said Mum as she released her hold on me, "Go on darling, you go and have your wee."
A moment later and she grabbed my cock again.
"Hang on," she said, "Let me get a quick taste of that delicious stuff, it'll be a shame to waste it!"
So saying she bent down and let the tip of my cock slide into her mouth and immediately she began vacuuming my precum from me. She let go after a few moments and stood up again.
"That's better," she said as she licked her lips, "Ok, I'll let you wee now."
"Yeah, got to drain the tank," I answered as I turned and pointed my penis at the pan, "Won't take long."
"Just when it was getting interesting too!" said Mum to herself as she licked her lips again then picked up her toothbrush.
She turned and looked at me.
"Isn't it nice; we've got all weekend ahead of us!" she said happily, "All weekend to have some fun!"
"What can I say?" I answered as I tried to concentrate, "Sounds good, but I've got to go..."
"Yes, you just carry on darling," said Mum, "I only want to clean my teeth - just ignore me."
Our bathroom was a fairly old-fashioned room with the toilet and wash basin alongside the bath, which had a shower built over it which meant that as I tried to pee, so Mum stood beside me as she brushed her teeth - and nothing would happen.
I was constantly distracted by the sight of Mum's generous breasts as they swayed and wobbled as she brushed and the distraction kept my cock stiff which in turn made peeing almost impossible.
"What's up dear?" asked Mum after I'd stood there for a while, "Oh dear, he won't go down, will he!"
"It's you standing there that's keeping him hard," I moaned, then added under my breath, "I wish you'd do something, like...like leave me in peace."
"Like what darling, what was that you said?" asked Mum through frothy lips, "You want me to do something did you say? What, something like help you to cum?"
No way did her suggestion help in cooling my ardour - instead my cock just jerked and seemed to grow stiffer and another little trickle of precum oozed from the pee slit. Automatically my fingers that were holding my cock to point it at the pan caught it and spread the slippery clear fluid over my knob before I realised what I was doing.
