Emma lay back on the mattress, and pulled Maisie on top of her. Bob's cock was raging in anticipation as he watched his wife wrangle the kid into position, but soon enough the girls were sharing the double-ender and he was greeted by a look of lustful readiness from his wife.

Springs creaked and twanged as he climbed onto the bed, and ceremoniously applied lube to Maisie's butt hole, working it in with a finger. Then he pushed in a tapered length of stainless steel, at first just an inch or so, then deeper and deeper into her body, stretching her hole until her sphincter tore and a terrified girly yelp of agony erupted from her lips.

Her squealing only served to excite Emma's lust. Now Maisie was trying to free herself. It was a hopeless struggle, and her squirming and kicking made the dildo wriggle inside Emma. She clasped the girl tightly and made the most of it.

"C'mon Bob!" Emma called, "We're waiting!"

Bob climbed aboard, his extra weight pushing the girls down into the mattress before he sank his cock deep into Maisie's ass.

Two females squealed and moaned in unison. Maisie tried to pull away from the pain that the dildo was inflicting on her girlhood, but this only had the effect of pushing her soft rump deeper around Bob's shaft. Bob pushed back, forcing her harder into Emma. Maisie yelped as the dildo rammed savagely into her immature cunt, and kicked her legs in distress.

Emma kissed her forehead by way of a thankyou, and Bob kept his cock pressed deep into her and enjoyed the panicky jiggling for a moment before starting to fuck in earnest, looking into his wife's ecstatic half-closed eyes as he slid in and out of the little one's ass.

Poor Maisie's limited life experience furnished her with no way to comprehend the rapidly unfolding ordeal, and her mind was as blank as a trapped prey animal's waiting to be torn apart by wolves.

And yet a guilty warmth took her. A sense that she was playing a part in an ecstatic unholy deliverance. Fight or flight only caused more pain, so she acquiesced, unwittingly playing the part of fuck toy perfectly.

Bob settled into a rhythm, ruining Maisie's sphincter as he gradually worked his way to balls-deep paradise. Maisie was quieter now, and apart from her occasional pitiful squeaks, the only sounds were those of earnest debauchery; Emma's breathy moans, the creak of springs, and the occasional slap of Bob's nuts against Maisie's tender bottom. Bob felt he could go on like this forever, knowing Emma would send him her secret look when time was up.

But apparently, it was a little too quiet for Emma. Seeking more stimulation, she suddenly squeezed Maisie's chest tight against her bosom in a bear hug, arched her back, and started fucking the girl hard with thrusting hips. Maisie bubbled a scream as the walls of her pre-pubescent cunt were ripped, and once again her limbs flailed.

"Oh Jesus fuck yeah!" Emma cried, sadistically rejoicing as much in the girl's agony as much as her own rapture. Bob came dangerously close to nutting, and so stifled Maisie's thrashing by pushing his pulsing shaft deep into Maisie's squishy guts and hugging the two girls in a sweaty embrace until their vigour was subdued and normal service resumed.

They let this cycle repeat a few times, letting Maisie's exhausted body collapse while they fucked, before livening things up once again with painful thrusts or a punch in her side, until finally Emma gazed at Bob with a melty, wanton look on her face. It was time.

Unexpectedly, she suddenly freed her arms, put them around Maisie's throat and pushed up. Bob hadn't expected this and laughed, then reciprocated, gripping the back of Maisie's neck and pushing back.

Emma looked up into Maisie's terrified eyes. "Time to sleep, little one."

"Ackkh," gargled Maisie, Drool ran from the corner of her pretty mouth and she tried one last feeble attempt to get free, scratching at Emma's face and bucking violently.

The desperately struggling, hot tight grip around Bob's cock was too much for him, and he started to cum, spilling waves of juice into the tight, wriggling softness. As he did, Maisie finally choked out, slumping limply and releasing her bladder. Warm pee gushed over Emma's snatch, adding to her own wetness and bringing her to a shuddering climax. She released her grip, her arms flopping to her sides and letting Bob and Maisie drop onto her in a carnal heap as the waves of a dizzying orgasm rocked her.

Bob clinched his wife tightly, squeezing the air from little Maisie's lungs. Still unconscious, she let out a long fart, causing the couple to giggle and Bob to finish emptying his balls.

The couple lay still for a few euphoric moments, then Emma spoke. "I hope we didn't kill her," she whispered, "chopping her up will be much more fun if she can still squeal."

"I thought," Bob countered, catching his breath, "That her squealing was 'doing your head in'."

"Meh," Emma laughed, "It's growing on me."

Bob slid out of Maisie's hole, and wiped a smear of blood and poop from his dick. It wasn't long before she dizzily opened her eyes and she lay silently between them, rocking and clutching her belly.

Now sated, rational thought resumed and they returned to the business in hand. Little Maisie wouldn't walk, so they had to drag her back to mum. After they had tossed her bloodied and dirtied little body back inside the cell and slammed the door, they showered and returned to the bed.

Bob slurped his tea. "You know," he said at length, "I did a survey, and apparently, two out of three people say they actually enjoy gang rape."

Emma giggled and passed him a spliff. "Yes, that was simply marvellous darling, we should do that again sometime, if you can find a slot in your schedule."
