Relaxing Retreat - Part 3 (Commission for Hyacinth)

Ever since their return from their retreat, and the subsequent days of indulgence, Iris had taken a turn for… it was hard to say worse, as both her and Tempest were thoroughly enjoying her new mania, but definitely a turn for the unwieldy, all things considered. It wasn’t enough for her to have a pair of tits that smushed against the ceiling and made conversations impossible from how loud they were, and it certainly wasn’t enough for her to be downing lactation supplements like they were candy. Her obsession with increasing the size of her bust, still kept miraculously dry despite its immense bounty, had made her turn to alternative methods.

The first hormone treatment had taken place two weeks before, after much convincing of her GP that it was absolutely something she wanted and that both her and her partner had discussed in depth. What her doctor didn’t know is that said partner was happily squirming around inside her room-filling cleavage while Iris spoke with them, barely hidden by the incredibly-stretched tarp the big swan had taken to use as clothing. The treatment itself was quite simple in its goals: increase her libido and boost her productivity further, and it was incredibly effective in both regards.

Those had been two weeks during which Iris could never be satisfied. Regardless of how much Tempest worked to give her what she wanted, the two swans never seemed to find an end to the female’s seemingly-bottomless pit of sexual desire. The smaller of the two would be beaten and broken down by his own attempts, and yet his partner would be demanding more, her slit still as needy as ever, pouring with her juices as it begged for a cock to fill it. This alone would be bad enough for her, but when put together with her increased milkiness, it helped turn what was already an immense problem into something akin to a localized cataclysm.

Iris’ breasts quickly became impossible to move for anyone but her. Against all expectations, the swan was still capable of pushing those monsters around, even when they began to literally break down the walls of their house and the two had to start making accommodations to move somewhere with more space. What’s worse, this didn’t seem to register with Iris herself; despite knowing that indulging herself in the same kind of sexual escapades as she always had would only make her milky issue worse, she continued to make good use of Tempest’s well-trained stamina, often having the poor boy stuck inside of her cleavage for hours at a time, when he wasn’t busy tending to her more directly. The end result? By the time Iris suggested the two head out to the beach to “stretch out”, she was already too big for their house and had to be moved out by removing one of the walls, and carried around a bust so immense that even when she tried her best to stay on the sidewalk, the road was still completely blocked.

None of this bothered Iris, who was simply happy to be out and about for the first time in what felt like forever. Even if other passers-by had to run out of the way to avoid getting bulldozed by a pair of tits the size of a literal house, she was happy to have a few hours under the sun with her lovely Tempest by her side… or, well, stuck inside of her colossal cleavage, but it was practically the same, really; as always, having her mate happily wriggling around between her titanic mounds only caused them to bloat even faster, threatening to tear her already-barely-there microkini into shreds before they had the chance to lie down and get the sunscreen out. Against all odds, the couple reached the shore, placing their towels down while Iris complained about the hot sand underneath her tits.

Then again, it wouldn’t take too long for things to cool down; seeing as her tits were about five or six times her height, she just had to wait for roughly ten minutes before the natural shade cooled things down enough for her to get comfortable. Due to the practical necessities that came with a pair of breasts that large, both swans had to set up as far away from the ocean as they could, just so Iris could have her back against the wall separating the beach itself from the street above it; any other position and she risked being smothered by her own bosom, especially with what she had planned for it.

At no point did the bigger swan intend to make that trip a wholesome one; the whole point of going to the seaside was precisely so she’d have enough room to grow out a bit more while waiting for their new house to get lined up, and to do so somewhere with not only enough room to stretch out in every direction, but with plenty of onlookers as well. It made for an interesting spectacle, considering she had eyes only for Tempest; it was so delicious to know that everyone around her desired her when only the two of them would ever get to savour the fine dish that was Iris’ body. It made her tits swell just by thinking about it, something that she welcomed with all of her heart.

But it wasn’t the main show, oh no. The two had brought along a cooler filled with drinks and snacks, as well as three large plastic bags filled with identical bottles. The nominal purpose of this immense stash of sunscreen was to provide enough protection for Iris’ sensitive body; she did have a lot of skin to cover, after all, and therefore needed a substantial amount of the stuff in order to make sure she wasn’t ever sunburnt. In reality, however, both her and Tempest knew the cream wasn’t meant for her, but for him.

Exchanging a couple of smooches before the smaller swan got to work, he dove back into his mate’s cleavage and began the arduous trip towards her nipples. This alone caused enough of a disturbance that those mammaries already began swelling, their cacophonous currents of cream drowning out any sound that wasn’t them, and making it impossible for Tempest to hear if Iris ever decided to stop… not that she would, but still. With a loud gasp and even louder panting for breath, Tempest emerged from within the embrace of those swelling tits, heaving himself onto the top of their curvature and dragging with him a whole bag of sunscreen bottles. Once in position next to one of Iris’ nipples… it was hard to get his eyes off of it.

It was “covered” by the microkini, though that basically amounted to having just enough of it hidden by a triangle of cloth that she technically couldn’t be charged with public indecency. It was still about half as big as he himself was, giving him the perfect target for what he was about to do. Tempest drew the bottles one by one, emptying their contents onto himself, making sure to slather up nice and proper before stretching his arms out and hugging that swollen teat, using it as his personal body pillow while rubbing his entire body against it. This had the immediate result of causing Iris’ back to arch after the sensations hit her all at once, her whole bust quivering and wobbling angrily as the milk production within was spiked to levels even she had never experienced before. Poor Tempest barely got two minutes alone with that nipple before the vibrations coming from below him caused him to slip and slide back into his partner’s cleavage, his greased-up body having too little friction to hold on.

As for Iris, she was having to deal with the end result of infusing her system with enough hormonal treatments to turn a desert into an ocean, to say nothing of taking so many boosters and supplements that it was a miracle she hadn’t overdosed already. Instead, her body went into overdrive, producing so much milk that she was having trouble keeping it all back. In truth, this was the only reason she was so big to begin with; though Iris had no doubt that her tits would receive one hell of a size boost after draining them down, she was still growing purely because of her own ability to keep her nipples from leaking… and for once, she doubted her ability to hold it back.

She wasn’t even gaining inches anymore, but feet, swelling in every direction, harder and harder as Tempest desperately tried to escape from within the confines of her bust, only serving to make her grow even faster than before. All Iris could do was beg for it to never end, her voice vanishing amidst the slorshing and churning of breasts that quickly overtook the road above her and rapidly approached the ocean. The last thing she felt before being completely buried was the chillness of the water lapping at the bottom of her breasts… and she wasn’t anywhere near done yet.
