Thanks to a power failure, we were given the rest of the day off. Marion gave me a lift so I got home about 2p.m. When I entered the front door, I heard music coming from upstairs. I thought maybe one of the girls, or Martin, my younger brother was playing hooky, so I went up quietly. The sound was coming from our room, was it Brenda , my younger sister ,then?

I decided to give her a fright so I opened he door quietly and looked around. It wasn’t Brenda no it was Martin lying on the bed, his trousers round his ankles and a pair of my panties wrapped around his cock which he was slowly wanking off.

“Well my little brother isn’t so ‘little’ after all, “I said walking to the bed and sitting on the edge. Martin was all flustered and embarrassed, he tried to hide himself.

“Leave it, “I said, “That’s quite a cock to be proud of. Have you shagged a girl with it yet?” Martin shook his head. “Have you had a girl play with it?” Martin shook his head again. “Well have you played with a girl's tits yet?” Once more Martin shook his head.

“Blimey you haven’t done much yet have you? Here let me help” I got up onto the bed, undoing my blouse and bra at the same time, then placed my hands around his cock and took over the job of wanking him off. At once Martin’s cock grew stiffer and bigger.

“There is that nice.”

“Yes, oh yes” Martin sighed.

“Well put your hand in my blouse then, it’s time you played with a good handful.”

I got my self in position on the bed so that I could wank his cock to best effect, soon it was as stiff as a board, with the foreskin pulled down around its head leaving a lovely naked purple top which I proceeded to kiss and suck. Marty lay there moaning in pleasure, and very soon I felt him start to jerk. I didn’t like swallowing spunk so I took my head away, but just the same, his powerful spurt caught me on the lips and face. And dribbled down onto my tits.

“There now, was that good?”

“Oh God yes, I’ve never felt like that before”

“Beats wanking don’t it?” I replied as I took up the lilac knickers he had been using for his wank, and wiped the spunk from my face and breasts. I left some on my lips and drew Martin to me kissing him forcefully so that he was able to taste his spunk.

“Now you must do some work” I said, and lay back on the bed spreading my legs and holding open my wet cunt.

“Come here, give me your hand, see my clit, this bit here, and now rub it gently for me”

Martin started to rub me off.

“That’s it, now harder, yes, good, now slip me a couple of fingers, don’t stop rubbing, in further, good, good”

“Oh Sue this is wonderful, but it’s wrong isn’t it?”

“Of course, but that’s what makes it so good, Oh keep it up, harder, HARDER HARDER, OH YES!!EEEEEEEEEEEEEEEARGHHH!!!”

I had my come and drew Marty close to me so that we could have one last snog. The others would be coming home soon, and we had to get cleaned up.

“Sue?”

“Yes?”

“Can we do it again? Can we do some more”?

“Of course, and next time you can fuck me, would you like that?

“Oh yes please sis. You bet!”

“O.K then, next week, when Auntie Mary and Uncle Bill are on holiday, I have to house sit for a fortnight and water their plants. You can help me”.

Â

The following Monday I went straight from work to their house, Martin had already arrived and had finished watering the flowers when I arrived.

“Hi Susie, I got off a bit early today, so we could save a bit of time. I was afraid you wouldn’t be here. It is all right isn’t it? I mean we are still going to.., well, you know, er do it?”

“Fuck , you mean?, Of course, a promise is a promise. I’ll se you upstairs in a minute. Did you think to get some johnneys?”

“Oh bloody hell no, does that mean we can’t?”

“No, don’t worry bought 4 packs, for the weekdays, and 2 on Friday!”

I went upstairs and stripped down to the sexy undies I had put on special. Martin was a very good looking young man so this was no chore”

When Martin came through the door he let out a low whistle. “ Fuckin’ hell Sue, you look gorgeous, soo sexy”

 I could se from the growing bulge in his pants that he meant it too.

We go to the bedroom and I get undressed Marty is sitting on the side of the bed watching me/
When I am only wearing my bra and panties I reach inside my bra to fondle each breast and rub each nipple.
Then I remove the bra and fondle both breasts at once, rubbing and gently pulling on my nipples.
Next I slide one hand in the front of my panties and rub my pussy.
Now I slide the panties off and use one hand to rub and pull on each nipple while I use the other hand to rub my pussy and slide one finger inside - slowly pumping it in-out and then I lick my finger, tasting my cream.
I have teased him enough as I kneel between his legs and start to slowly and deeply suck his shaft as I rub my hands all over my breasts while I am rubbing my pussy at the same time - now sliding one finger in-out until his shaft is good and hard.
Now I let his cock slip from my mouth as I lean down to wrap my breasts around it and I start to rub the hard nipples and I look up at him with eyes filled with passion and I say ‘titty-fuck me’ as I rub my breasts up-down his shaft and I pump it up-down at the same time.
I pull on both of my nipples then I hold my breast for him as I continue to pump his shaft and I rub my own clit with one hand and slide one finger of the other hand in-out my pussy and Marty starts to come.
As he’s climaxing he starts to cum between my tits and I look at him and tell him “Fuck my mouth and feed me your spunk” as his shaft slides from between my tits and I lean down to suck it slowly-fully into my mouth.
I am now fingering my pussy madly as I use the other hand to rub Martin’s cum all over my breasts and he is pumping slowly into my mouth, pumping the last of his cum as I swallow it all this time while climaxing again - my body shaking all over.
I let his soft shaft slip from my lips and pull my fingers from my pussy - I lick my fingers clean of my cream and we share the flavour (my cum and my cream) in a deep tongue-probing kiss.

“Now we should be able to enjoy a nice long fuck, come here and put this Johnny on”

Gently I slide the condom over his still erect cock, then I lean back, open my legs and softly say “Now Marty come in and fuck me now” Marty advances and aims his prick at the mouth of my cunt, he is pushing nervously so I put my hands on his bum cheeks and pull him into me. When he is tight into my cunt I swing my legs over his shoulders so that he is penetrating me fully with every centimetre of his young cock.

“Oh Sue this is great, even with a condom on I Can feel you it’s so smooth so wonderful. Shaggin’ my big sister it’s fuckin’ ace I mean I….”

With that he found the strength to shoot again and fill the condom.

I eased the condom from Marty’s prick and poured the contents into my mouth, some ran down my chin and onto my tits. Marty rubbed that into my skin murmuring as he worked.

“This is so fucking sexy Sue I have never imagined that this is what men and women did together, who taught you to be so good?”

“Tommy” (My elder brother)

“What? You and Tommy fucked together!?”

“Uh-huh, and soon it will be your turn to teach Brenda, would you like that too?”

“Well I dunno, it can’t be as good as with you. Her legs are thinner and she hasn’t got nearly as much tit “

Then we snuggle together in each other’s arms and explore each other’s bodies.

“You know my mate Alan?”

I thought then remembered the tall blond teenager that Marty often hung out with. “”Yeah, what about him?”

“He fancies you like mad.

“How do you know that?”

“ ‘ Cos he’s told me often, whenever we talk about girls, he talks about you, how he loves your long legs, and reckons you’ve got a lovely pair of tits”

“Oh really? What are you getting at Marty? Do want to bring him along one night and watch him fuck your sister? Is that what you are saying? “

“Would you? That would be fucking great”

This had got Marty so worked up that his cock had stiffened up again nicely, so I rolled him onto his back and mounted him, sliding slowly down his erect cock, holding the skin around my clit back so that it stood out pink and proud.

“Oh that’s it Marty push that cock in me, hurt me with it. Oh yes you are a good fucker, oh slip out and fuck my bum now, I want to be really hurt.”

I got onto all fours, my arse in the air; Marty put his hands on my hips while he lined up his cock at my bum hole.

“In here? In your bum hole?”

“ I want to be a dirty as I can”. Marty wasted no time he gave one hard push, and thanks to the lubrication of my love juice on his dick he slid into me easily stretching my back passage to the limit.

“Eeeeie! “ I screamed in pain “ God that hurts like hell, but fuck me Martin, go on ride me. It hurts but it’s a good hurt”

Marty pumped his cock into me while I continued to squeal at every new stroke. Then Oh bliss! Marty found enough in him to come again and shot his spunk into my arse. It caught me so much by surprise that I lost control and orgasmed again. When I stopped jerking and moaning, Marty slowly pulled out.

“Go and clean up” I said,” Then come back and we’ll talk about Alan”

When Marty returned from the bathroom his knob was still fat and red, although it has lost its stiffness. I lay on my back and played with my nipples as we spoke.

“Now what would you like me to do for Alan? Would you like me to let him fuck me while you watch? Or would you prefer to join in, have a threesome?”

“What both of us doing you together?”

“Yes”

“Fucking hell Sue, you are a hell of a sister, you have sex with me, and don’t mind if I bring my mates along as well”

“Go easy, I said mate, not mates, I’ll have sex with you and Alan, but no more than that, just the two of you. 0K?”
