Onwards to Venus!

Two months later,

Standing in front of the bed in his cabin aboard the HMS Aurora, one of the ships of the latest class of aerial light cruisers to be commissioned into the Royal Navy, John was performing one last check of his equipment, making sure that everything was there and in order. Obviously, since he and Lexi were going to be on their own on Venus, John made sure to be extra careful that his weapons were all up to snuff.

The most conspicuous of those was the gift that he'd received from Colonel Smithers-Jones; the colonel's old howdah pistol, a true monstrosity of a weapon in the shape of two drastically shortened rifle barrels fitted onto a pistol grip. The howdah pistol had initially been designed to be used by proper gentlemen in the British Raj, in case they'd end up being perilously close to a snarling tiger. And although John very much doubted that he'd be running into tigers on Venus, he still appreciated the fact that a pistol that could deliver two rounds of high-calibre, high-velocity ammunition might come in handy in the dense jungles that covered the vast majority of the planet's interior.

Apart from the monstrous two-barrelled pistol, John would also be carrying his Webley revolver and the new Lee-Metford service rifle, the first of its kind to be a magazine-fed, bolt-action weapon. Apart from firearms, John would arrive on Venus carrying a knife and a machete, although he had been **** to admit that his sword would likely be quite useless on this particular mission, and so would have to be left behind.

Having checked his weapons, John turned his attention towards the other items that he was to carry with him once they got to Venus, from the binoculars which would probably only be useful if he and Lexi happened to stumble across a hill or knoll that would bring them above the foliage and undergrowth of the jungle, to the canteens that would prove vital for their survival, providing that Lexi's vaccine would allow their bodies to handle the organisms in it. Next was his two sets of clothes, minus the trousers that he currently had on, which consisted of trousers and shirts that he considered as good a compromise between lightness and durability as possible.

John then let out a chuckle as his gaze turned to the outfits that Lexi would be wearing, and how their skimpy size meant that there were much more of them what he would bring. As he looked down at the various thongs, tops and whatnot that were laid out on the hastily rearranged bed that the two of them shared, John widened his smile as he reflected on how Lexi had worked diligently and efficiently to recreate her wardrobe before they'd left Earth, replacing the modest dresses, skirts and blouses that she'd previously worn with some truly scandalous pieces of clothing.

Feeling his cock grow harder and start throbbing against his thigh, John picked up one of Lexi's thongs, admiring how tiny the leopard-print piece of semi-sheer material looked in his hand.

"Enjoying yourself?" Lexi suddenly asked from behind John, causing him to turn his head and look at her, which in turn led his cock to become even harder.

Having just returned from her much-needed morning bath, Lexi had a towel slung round her neck, though her dark hair was still shimmering wet and tiny beads of water glistened against her tanned, silky skin, one of them slowly trickling its way down into her cleavage as her massive, fully exposed tits protruded out far in front of her, and with more of them moving at equally slow speed as they crossed her toned midsection, seemingly heading for her bald, pink slit.

"Oh yes," John returned Lexi's smile as she began sauntering towards him. Since their cabin wasn't particularly big, being not more than a few yards across, it didn't take her very long to get up behind him, with the two of them sharing a breathy gasp when her heavy boobs came to press against his muscular back.

"What about you? Did you enjoy your bath?" John asked Lexi as she snaked her arms round his waist and planted soft kisses along his right shoulder, slowly moving her soft lips towards his neck.

"It had been more fun if you'd come along," Lexi playfully lambasted John, while using her fingers to deftly undo the front of his trousers.

"Well?" John began, not saying anything more as he instead diverted his eyes downwards, observing with silent approval the skill and grace with which Lexi opened up his trousers. During the time that had gone by since they'd both tried her vaccine, Lexi had gotten much practice in stripping John of his clothes, so that by now she knew exactly what she was doing as she grasped hold of the waistline of his trousers and started to shimmy them downwards, inching them down his thighs to have first the fat base of his fuckpiece be unveiled, then more of its thick, vein-ridged trunk, with John feeling Lexi's warm breath on his neck and her huge, lushly tanned knockers heaving against his back as she wriggled her hips in conjunction with her wrists.

Finally, John's trousers were pushed down far enough that his achingly hard cock first coiled up and then sprang free of its confinement, a heavy dollop of precum being jettisoned from the fist-sized crown of his turgid fuckmast and falling down to smack against one of Lexi's tops that laid splayed out on the bed in front of him, the release of clear prejizz soaking through the front of the thin band of white silk which was meant to be tied round Lexi's magnificent bust, pushing her perfect tits together in such a way that she could use her cleavage to store banknotes.

Rather than to seize hold of John's cock, like he knew that she desperately wanted to, Lexi slipped out from behind him and instead came up beside him, her plump, glossy lips pulled back into a predatory smile that perfectly conveyed her boundless hunger for him and his colossal fuckpiece as she reached in and snatched her leopard-print thong from his grasp.

"So, this is one of your favourites then?" Lexi asked John, referring to her tiny piece of underwear as she draped its thin, triangular front over his cockhead, its thinness ensuring that the vivid purple of the crown of his fuckmast could still be seen underneath it as her fingers moved aimlessly to the spaghetti-strap waistband of the gloriously undersized garment, the top-heavy vixen soon letting out a moan of lustful approval at how her lover's steel-hard cock barely even budged as she pulled the waistband back, stretching it like she would the string of a bow.

Eventually, and just like it seemed as though the thong's waistband would snap, John surprised Lexi by unleashing another powerful jet of precum. Caught unawares by how John's entire cock bucked from the **** of the blast of prejizz that came coursing through it on its way out through his widened pisshole, Lexi yelped and let go off the thong, which duly shot through the air, being carried forwards by the momentum of his release of precum until it smacked into the wall, to which it stuck, thanks to how it was soaked through by his pre-orgasmic juices.

Giggling at what John had just done, Lexi leaned in closer to him, slipping in underneath his left arm and bringing her lips into contact with his, the scientist-turned-superslut soon groaning into John's mouth as she felt him tighten his arm around her slender frame and thus pulling her even closer against his thicker and brawnier form.

Just as their passionate kiss had run its course, and as Lexi was looking into his eyes, John released another high-powered surge of precum, this one stretching itself into a long translucent flash that soared upwards at angle that brought it smacking into the lamp hanging over the bed, producing a dense clang as it was deflected off the metallic lampshade and then causing Lexi to unleash a girlish yelp when it finally came back down to smack against her juicy bubble butt, landing on it in a strategic enough spot that it could begin trickling down into the deep, narrow chasm that ran down the centre of her heart-shaped ass.

Once more reacting to John's actions with an intoxicating giggle, Lexi withstood the temptation to kiss him again, instead slipping away from him and having her face remain contorted into a sultry, lustful smile as she backed across the small room all the way up until her buttocks were cushioned against the wall behind her.

John was so quick in moving towards her that Lexi had no need to send him her most fetching come-hither look, but she did so anyway, before forming her lips into a ring and releasing a heartfelt moan of lust as she eyed him walking towards her with fast, determined strides.

Knowing that she didn't have much time before John would be upon her, Lexi spread her legs and gave her juicing honeypot a playful slaps, indicating to John which one of her holes that she wanted him to fill first.

Before that would happen however, John squeezed his body against Lexi's and swept her up into another wholly uninhibited kiss, her boobs mashed against his chest while the head of his cock was caught between them, with Lexi ceasing to wrestle tongues with him and instead moaning into his mouth upon having his latest blast of precum rocket itself straight upwards to splatter itself against the underside of her chin. John, meanwhile, was having a hard time not noticing how Lexi's juices were spilling out onto his beating balls as they dangled directly beneath her soaking wet pussy.

Breaking their lip-lock, John and Lexi worked together to line his cockend up against the entrance to her slit, the length of his dick being a hindrance that they overcame with surprising ease, and soon a girlish whimper escaped Lexi's mouth as the raven-haired vixen felt her sex be invaded by the plump, flared business-end of John's fuckmast. Despite the countless times that they had fucked each other silly during the last two months, Lexi's pussy felt as tight as ever as John fed more of his cock beyond her puffy labia, to the point where he still had difficulty believing that it was possible for his massively thick member to fit inside her tight fuckhole.

Any lingering concerns that he might have had about it being uncomfortable or unpleasant for her were proven unfounded, as they always were, when she suddenly let out a shriek of orgasmic bliss and had a succession of squirts of girlcum erupt from her honeypot, the clear fluid shooting out over and past the trunk of John's cock to impact on his balls and stomach.

"Yes!" Lexi let out a scream, her hands pulling at John's neck as he rushed to fit more of his cock into her spasming pussy, his balls being milked of more rich spurts of precum as he managed to fit enough of his member inside her that she could snake first one, then two legs round his waist, displaying her need for him to fill her up completely by using her legs to push his fuckmast deeper into her snatch.

No matter how many times that he experienced it, John still couldn't fathom how the entirety of his cock could possibly be made to fit inside the snug confines of Lexi's contracting honey box, but he had no interest in questioning the reasons for it, opting instead for starting to fuck her with fast, short thrusts, which she was sure to try and meet by bucking her hips back and forth between him and the wall behind her, her face now a mask of undiluted ecstasy as the powerful throbbing of his cock helped bring her to another earth-shattering climax in no time at all, which in turn brought about John's stomach and balls being further soaked with her juices as girlcum shot out of her cock-stuffed snatch.

"YES! Fuck that monstercock feels good in my pussy!" Lexi cried out as her whole body still quivered from her latest orgasm, girlcum still exiting her honeypot as the words exited her mouth.

"Cum for me baby!" Locking eyes with John, Lexi started urging him to blow his load, her voice being defined by something halfway between sultry sexiness and earnest pleading as she continued to meet his frenzied thrusts, "Cum for me, fill my slutty pussy up with cum!"

Proving just how easily swayed he was by Lexi's pleas, John buried his cum-cannon all the way inside her twat one final time before releasing a lengthy jet of jizz, with the feel of his spunk shooting into her sex serving as the trigger for Lexi's next orgasm, one that particularly intense even by her standards, and a satisfied shriek that could be heard all throughout the ship now flowed out of her wide-open maw as her eyes were shut tight and girlcum exploded out of her pussy even as it was being pumped full of John's thick balljuice.

Writhing against each other all throughout their joint marathon-length orgasm, John and Lexi eventually stopped moving and resumed looking into each other's eyes, and this time it was Lexi who was first to snap out of the afterglow of her momentous orgasm and drive her head forwards, catching John in another spirited kiss.
