"Sanddy!" Recovered enough from the experience of having her nuclear bomb of an ass taken hard and simultaneously by the three biggest, brawniest and sexiest slabs of manmeat she'd ever seen that she was now merely extraordinarily horny rather than locked in a state frenzied fuck lust, Diamond endeavoured to say something. However, she only managed to get the one word -- or name, rather -- out before Robert went after the target of opportunity that presented itself when she opened her plump lips to speak.
"Robert!" Certain of what was happening despite Ian's mammoth dong being laid across her eyes preventing her from seeing anything at all, Sanddy feigned annoyance at her boyfriend's brusque behaviour. She did so over the sound of spit and air being pushed up out of the super-stacked American porn starlet's throat as he plunged his now seventeen inches long cock into it.
"What?" Robert asked, his tone matching that of his girlfriend while she tilted her head and resumed trying to snake her tongue round the immense girth of Ian's steely fucktool, snatching up the ropes of spit and precum attached to it with her wet muscle. Still, the young stud proceeded to pull back out of Diamond's throat.
"Slut's up to something," Laura said, still holding Charles by his colossal cumtube as she positioned herself next to Candi's head, "I can tell."
"That's not really a surprise, honey," With his dick laid out across the gorgeous faces of the trio of teen, hard-bodies bimbo sluts, Ian pushed forwards, letting his shaft slide over their eyes and gradually tightening his powerful pc muscle to overpower the laws of gravity and raise his cockend until it smacked up against the glistening lips of Laura's pussy and became lodged against the juicing fuckhole positioned between them.
"Fuck!" Since she didn't have her gob and gullet stuffed full of Robert's schlong at the moment, Sanddy was able to keep on talking freely when she wasn't lapping at the giant pillar of unyielding cockmeat being pushed across her face, "Who needs sunglasses anyway?"
"Not getting nearly enough ass to mouth here, stud!" Candi too took advantage of her mouth and throat being unblocked by trying very eagerly to get Robert to block them, "Come on, fuck my throat so good the first thing I taste when I wake up tomorrow is Diamond's porn whore ass!"
"That taste's gonna be cum, slut," Laura informed her sister, whilst eyeing Ian like she was about to hurdle across the threesome of buxom teens and have either one of her nether holes -- although in all honesty it would probably be her ass -- impaled on the pussy-popping, ass-stretching monster of a cock that he was currently using to tease her needy little cunt, "Fucking stud... Could make a fucking stallion jealous!"
"Shit..." Gasping when Ian, who was smiling with satisfaction at her words, proceeded to rub the flared and somewhat spongy crown of his fuckpiece against her tiny but extremely engorged clit, Laura couldn't keep up when Charles -- now on his third or fourth wind at least -- slipped free of her grasp.
"Big-titted, sizequeen WHORE!" First reminding everyone of his presence through what started out in a perfectly normal speaking voice but quickly transformed into a barbaric yawp fit to be sounded across the roofs of the world, Charles then threw his hips about like he was practising his golf swing and using an eighteen-inch piece of wood to do it.
THWACK!
"FUCK!!" Filling up the room first was the dense, sharp and very loud sound of Charles' fuckmast smacking across the full, ballooning length of a pair of asscheeks turned to perfection through a combination of good genes and relentless physical regimen that was about 10 % working out and 90 % fucking, sucking and generally worshipping monstercocks with the zealousness of the recently converted. The second was Laura screaming in wanton bliss and total surprise at the impact.
"Way to go, Charlie!" His balls already rubbing tight against Sanddy's cheek as her presence there hindered him from moving forwards further, Ian voiced his approval of his colleague hammering Laura's pussy onto the business-end of his cock.
"SPANK MY ASS WITH YOUR COCK!!" Laura too voiced her approval of Charles' actions, in the form of a blissful shriek coming as she felt her labia curve themselves round the bulbous shape of her boyfriend's cockend. On some level, having it inside her was like being fisted, only this was so much better in so many ways that the comparison wasn't anywhere near as fitting as it would appear at first glance.
"Take it!" Through some miracle, Charles was still wearing his glasses, and though they were fogged up to the point of droplets falling from them when he swung his hips, the size of Laura's tantalizing, ball-draining ass was such that it was impossible for him to miss.
On his second blow -- one that sound Laura's pussy impaled right up to the raised brim of Ian's cockhead, she threw her head back and squirted, crying out once again while her clear juices streaked onto the shaft of Ian's schlong and splattered against the side of Candi's face.
"Yes!" Without the slightest inkling of hesitation, Candi thrust out her tongue and curved it round the corner of her mouth, stretching out as far onto her cheek as she could and greedily lapping up her sister's ejaculate.
"Open wide..." Robert said, and suddenly something very big was being rubbed very delicately against Candi's tongue, and followed it into her mouth before coming to a halt in the insurmountable suction that she applied onto it.
"Yeah, taste that ass," An edge developed to Robert's voice as Candi sucked and slurped on his plump bell end, with only the occasional brief pause to let out a lustful moan or to swallow the precum that poured onto her tongue as if from a wide-open tap, "Suck the taste of bimbo porn slut's ass off my cock..."
"Sanddy!" Now able to speak again, Diamond picked up from where she'd been interrupted, "The camera! I want to see it!"
"See what?" Somewhere underneath the granite-like shape that was the shaft of Ian's schlong there was a naughty sparkle in Sanddy's eyes.
"My ass!" Diamond's voice started breaking as her lust flared up again when her words drew her focus towards the hole buried deep between her cheeks and what had been done to it minutes earlier, "I want to see what these motherfuckers turned it into!"
"Oh, that..." Sanddy giggled before rolling out from underneath Ian's cock. The moment that she did, Ian was on the move. If thus far what Charles and he had been doing to Laura's pussy and ass could have been likened to a hammer and anvil, now the anvil was charging forwards.
