The Prologue
My twin sister Matilda was staying with us.
She had just started a new job as an HR assistant for a London based company.
She hadn't managed to find her own place yet, so I said I would help her, and in the meantime, she could come and stay with me and Sam my boyfriend.
I was very close to Matilda; we were pretty much identical in appearance and personality, and we shared all our secrets. It's not all we shared. We were very intimate with each other. She would come and climb into my bed after Sam had gone to work on a Saturday and snuggle up to me.
That particular morning, she had slipped into bed naked, and I had woken up to the very pleasurable sensation of her licking the latest injection of Sam's cum out of my pussy...
"That's very naughty, you naughty sister! - even if it
is
appreciated! What would Sam say if he found out?!" I exclaimed.
We spent another lovely day together, sunbathing naked on the balcony in the hot summer sun, and chatting and drinking cocktails, and still continued when Sam returned from work. He had double the candy to ogle! But after a few more drinks we decided to go inside, it had turned muggy and very humid. The air felt heavy with an ominous pregnant calm.
That night, as expected, there was a terrible thunderstorm. One of the thunderclaps was so loud it woke me up - although not Sam: after a few more drinks before bed, he could sleep through anything.
There was a quiet little knock at the bedroom door.
"Come in!" I whispered loudly.
"I can't sleep. I'm frightened..."
"Oh okay. Come and get into bed next to me."
We had a superking size bed so there was plenty of room for her to climb in on my side.
"I think the storm is passing over anyway. Just cuddle up and go to sleep. Night night."
The Action
"GLK GLK GLK GLK GLK GLK GLK GLK!!"...
I woke up to the sounds of slurping and slobbering. And it wasn't my pussy being licked out. It took less than a second for me to come to, and work out what it was, and where it was coming from. And quite a bit longer listening to it, intrigued, quite fascinated, and also faintly amused; pondering what I was to do about it...
GLK GLK GLK GLK GLK GLK GLK GLK!!
It was Matilda sucking Sam's cock noisily and enthusiastically!
GLK GLK GLK GLK GLK GLK GLK!!
Sam may have been half awake or he may just have been enjoying his vivid dream of his cock being sucked splendidly by me.
GLK GLK GLK GLK GLK GLK GLK!!
Except it wasn't me. It was my very naughty twin sister. And I was going to have get very angry with the bitch! I would have to deal with her firmly and decisively. And I knew how...
"Fuck me now!" I whispered in Sam's ear. "Wake up! I've been doing a lovely job of sucking your cock and it's gone really hard, now pull me up and fuck
me
really hard! Right now!"
And that's what he did, or thought he was doing, in his half-conscious state. It was actually Matilda he pulled off his cock, hauled up the bed by her shoulders, got his leg over her bottom as she lay flat on her stomach, and once on top of her, forced his very hard cock deep into her (more likely than not) wet pussy from behind.
"Ooooooooohhhhh?" she had exclaimed quietly in expectation as he pulled her up the bed...
"Aaaaaaaaahhhhhh!" she gasped in gratification and submitting pleasure as he penetrated her.
"Oooooooohhhhhhhhhhhh! Yeeeeesssss!" she exclaimed in a long appreciative moan of sexual arousal as Sam forced himself even further into her and started fucking her powerfully and more vigorously!
And Sam was quickly fucking her hard and fast, just like he did me. He was a virile stud. In the dim light I could just see the back of Matilda's head jerking, reciprocating in time, as his relentless pounding was pushing her face deeper and deeper into the pillow. While I was just lying there motionless, observing and listening...
"Mmmooooooh!"... "Mmmoooooooooh!"... "Mmmooooooooooooh!"...
She was making louder muffled groans into the pillow each time Sam slammed into her ass as he attempted to get his cock deeper and deeper inside her.
"Mmmmmmmmaaaaaahhh!"...
She moaned in subjugated pleasure...
"Mmmmmmmhhhhhhhhh!"...
I hope she doesn't think she's going to get to enjoy this
too
much - or get away with it... He's fucking her good all right, but he thinks it's me. He needs to know! And she needs to pay! l reached over and turned on the bedside lamp...
"Uh Ohhhhhh!" she groaned, exposed...
That was enough for Sam to open his sleepy eyes and look down, and then over at me...
"Ohhhhhhhh?" she whined, discovered...
"What the fuck?!" he mumbled confused.
"Aawwwwwwhhhhh!" she moaned, desirously...
"Don't stop!" I commanded, "Turn her over and fuck her more! The bitch was sucking your cock while you were asleep. Now you can give her what she wanted! Now do as I say! Turn her over! And fuck her hard!!"
"Ohhhhhhhhhhhhhh!" she wailed, excitedly...
Too engrossed and too
engaged
to argue, Sam obediently complied and decoupled without protest. Having completely disengaged, he immediately flipped her over,
re-engaged
emphatically by slamming his cock forcefully into her open wet pussy again, and started fucking her hard and fast, as requested, like a very rough obliging gigolo, in the missionary position. Totally re-engaged...
"Fuuuck!" she gasped, re-entered...
"Oh! Fuuuuck!" she gasped re-impaled...
"Yes! Fuuuuuck!" she gasped fully filled, squealing clutch re-engaged and being driven hard and fast...
"Aaaaaaahhhh! Fuuuuuuck!" she wailed, opened up and accelerating helplessly out of control...
"Fuuuuuuck!" she gasped, re-occupied...
"Of Fuck! Oh! Fuuuuuuck!" she gasped re-consumed...
"Fuuuuuuuuuuuuuuuck Meeeee!" she wailed repossessed and totally fucking owned...
"Oh Fuuuuuuck!" she gasped, overcome...
"Of Fuck! Oh! Fuuuuuuck!" she gasped overpowered...
"Fuuuuuuuuuuuuuuuaaaaaaaarrrrgghck!!" she wailed, totally fucking overwhelmingly impaled, possessed, and involuntarily displaying complete loss of control...
