The Caravan Park

Kay swung around and looked guiltily into my eyes, as if she knew she shouldn't be cumming but she couldn't help the waves of pleasure building within her. I looked back and smiled, trying to reassure her that it was OK but was relishing the experience. She threw her head back, gasping, as the first waves of a second and deeper orgasm tore through her.

Her arse muscles clenched hard around my invading tool and judging by the wetness on Trish's palm the juices flowed freely from her squelching cunt. Her body shook and quivered, she bucked her hips back up at me as I continued to drill her back passage, assisted only by the lightest touch from Trish's other hand.

Trish kept Kay on the edge expertly, she frigged Kay's clit in time with my more urgent and involuntary thrusts. She knew that I was doing her on my own and wouldn't stop until I came.

I gripped Kay's taut but clammy buttocks as I swung my hips deeper and deeper into her yielding back passage. Trish hovered at my side and concentrated on pleasuring her half sister, barely pushing at my torso at all. I was near the point of no return as Kay relaxed her arse muscles to allow my hard cock in ever deeper. She was panting loudly as I grabbed her hips and drove my cock deep into her arse. Trish alternated her fingers between Kay's snatch and clit to keep her close to the verge of orgasm.

I even leant back to get a better view of my cock as I drove it, unshackled by lust, in and out of her hot rectum.

My legs quivered as the tell tale tingle started to rise from deep within my balls. I couldn't help but cry out as I sensed the cum rise in my tool. I was lost in my own passion and for an instant had forgotten that Trish was there to degrade her sister and that I, or rather my cock in Kay's arse, was the instrument of her revenge.

Trish, knowing from the tensing of my buttocks that I was on the verge, drove a finger, tipped by a sharpened talon, knuckle deep into my arse. She prodded the sharpened nail in deeper to encourage me to keep my rhythm as I sped, with my groin now slapping Kay's arse loudly, towards an intense and unbridled orgasm.

I cried out and my butt hole clenched tight against Trish's invading finger as my cock erupted thick semen deep into Kay's hot bowel. I fell forward and on to Kay's back, panting as the orgasm ripped though me.

Kay came as I flooded her arse with my hot seed, I forced her chest against the cold table surface as she struggled against the waves of pleasure that she knew she shouldn't feel from being sodomised.

I could feel a shake in her loins and a slight hissing noise as, judging by the pools of warm liquid on the flat of the table, she squirted cum into her sister's palm.

Trish withdrew her hand in shock and surprise at the intensity of her sister's pleasure. Kay lay flat in a stunned and guilty silence, her chest heaving, as I gradually picked myself up and off her sweat covered back.

"Eat it out. Eat your cum out of her arse." Trish demanded as my cock drained of its load, slipped from Kay's distended arse.

I was so turned on that I sank to my knees in meek compliance. Trish thrust my head directly in front of Kay's blood red and open ring.

"Fart his cum out, fart it out like the slag you are." Kay obeyed, her spirit had been broken and I watched in awe as she winked and pushed my cum from her gaping brown eye.

Her arse muscles tensed and my cum oozed from her distended butt hole in a series of squelchy queefs. The thinning white liquid trickled out of her pink and gaping hole, down the slit of her cunt and on to my waiting tongue.

"Drink it, drink it up" Trish shrilled as she held my head firmly in place.

The salty fluid ran down the cleft of her puffy cunt lips, I leant in and licked with relish to taste our combined cum, without Trish really forcing me. Kay squirmed and shuffled as my tongue ran along the length of her cunt. Again she responded by pushing backward and invited me further in.

Trish noticed that I was pleasuring Kay on my own accord, she grabbed her upper arm and jerked her off the table and on to the floor in front of me. Our arms remained locked painfully together as she Trish swung her down and in front of my dripping cock.

"Suck him hard again. He can't resist, he's only a man."

It was true, once upon a time Trish could make me hard by just flashing her tits and I would almost cum in my pants if she flashed her neatly trimmed cunt.

I felt guilty that I had been satisfied and had let my lust get the better of me.

Kay sank her mouth over my drooping tool and within a second I had forgotten Trish was even there, let alone her motives. She was good and I was indeed weak. Her hot mouth engulfed my end and her expert tongue flicked and washed over and around my tender end making me hard and ready for action in an instant. She drew every last drop of cum from deep within my cock and made my balls ache with, under different circumstances, the prospect of filling her hot mouth with a fresh load of my salty fluid.

"Lick his arsehole. Make him ready for this" Trish said as if sensing my enjoyment. She delved into her handbag and brandished a huge black strap on. "You have as long as it takes for me to get this on."

Kay, bless her, dipped her tongue in my arse and smeared as much of her saliva around as she could within the time given. She even dipped her fingers into her own cunt and smeared her cum around my tender ring.

I tried to angle myself as not to allow Trish to fully and easily enter my back passage but she swung me around by the hips and with Kay kneeling at my feet in front of the table she offered the tip of the black plastic member to my arse crack.

I almost passed out, as with one forward lurch, Trish rammed the huge black dildo into my arse. It almost lifted my off my feet. I looked down at Kay, her eyes were full of distress but pleaded with me not to cry out.

Trish fucked me over the table edge, hard and rough until my arse gave in and my muscles relaxed. The whole caravan rocked with the force of her ramming the thick black rod deep into me.

"Suck him. Wank him off as I fuck him. Make him cum." Trish barked out as she drove in as deep and as fast as she could.

Kay took to the task as if her life depended on it. She sucked at my cock and stroked the meat up and down with great speed.

I rested my hand on her head as Kay expertly took my end between her soft and warm lips and began to draw at my tender end. Her hand was still cuffed to mine and rested at her ear as she drew my tip in further and swirled her tongue around and under the head before sucking me into the supple limit of the back of her throat. She withdrew, still sucking hard and wanking my shaft slowly before repeating the process slowly and sexily.

The only thing that I couldn't do was savour the vision of her tending to my cock as her head was below the edge of the table and Trish was pounding my arse upwards.

I decided to try to concentrate my mind on Kay's efforts and after a while her expert and tender ministering seemed to be taking the upper hand or maybe I was actually starting to enjoy the arse fucking, but in any case I felt the tell tale tingling in my balls.

My cock must of swelled in Kay's hot mouth because she sped her actions and began pulling and sucking rigorously at my cock. I came with a sigh and was surprised at the intensity of the sensations as she pulled at my shaft and let Trish see the stream of cum shoot from my cock and on to the table to join the pool of her cum running on to the floor beside us.

After three or four powerful squirts my legs buckled and the giant dildo flopped from my battered and distended rectum.

"Lick his shit off of my cock." Trish demanded as she grabbed at Kay's head and thrust the black member at her mouth.

"Open up or I'll break your fucking teeth." She hissed as Kay curled her soft lips around the satin black shaft.

Kay gagged and wretched as Trish forced the huge black rod deep and down into her throat. After a few jabbing thrusts Kay fell back in exhaustion.

I was done in, my legs had gone and all I could do was look across at Kay, red faced, puffing and cowering on the floor at the foot of the table with a stream of our mixed cum dripping into her bedraggled hair.

Trish stepped out of the harness and carefully placed the ribbed black dildo on the table.

"Now you know what I did to Steven except I made him taste his own arse." She said as she tapped at the black plastic member.

"You can have him and this, you useless bitch." She hissed before storming out of the caravan door.

We paused and were unable to say anything as, seconds later, the door burst open once more and a small key was tossed into the centre of the small caravan.

I looked at Kay, her face wore the guilt of her sister's actions and the shame of her own inadvertent lust. She refused eye contact as I stooped to pick up the key and release us from the cuffs, still painfully restraining us.

I wish that I had the courage to admit that my lust had got the better of me too.

Kay picked up the broken scrap of material that had once been her thong, stood and left in silence without a backward glance.

I haven't seen her at the park since. I am not sure what I would say to her even if I did. I am now waiting for another transfer and just hope that this time Trish will leave me alone.
