So unique to find someone that likes to think about the ramifications, and apparently, would embrace the obstructions and challenges that huge breasts would present. Beyond weight, the obstructions largely rest on the size and height of the breasts; larger and higher more pronounced; lower less pronounced. Most all of that is because arm movement is obstructed by the breasts.
I agree that a natural slope can certainly look attractive, however, by a certain size, if one is to maintain any hourglass appearance, there has to be a bottom limit and I would suggest it is perhaps 2" below the navel. Trust me, I think about these things. At that level, when sitting upright, your breasts are just lightly resting on your thighs, and as you lean forward, they press firmly. If we are talking about Beshine, you can see that she can lean slightly forward without difficulty, however, to lean further forward, she literally has to use her arms and lift her boobs and place them further down her legs as she leans. That is truly fascinating. If she had just natural breasts, they would just squish as she leans.
Which brings me to another point you brought up; natural versus implant, and perhaps, something in between. I have wondered if a girl with very large natural breasts, got very large implants, what would the result be? With all that tissue surrounding the implant, would it offer a softness Beshine will never have? Clearly, you would need a internal bra, which you can specify the lowest point you want your breasts to be, but just theorizing that, if you were already L cup or bordering on gigantomastia, wouldn't that create a breast that hangs slightly into a large spherical mid and bottom as opposed to Beshine spheres? Obviously, picking the point to which they will hang would reflect on the shape, but we have all seen that implants that have migrated south is not an ideal solution, unless they can be inflated to enormous size.
But still, one of the aspects that fascinates me is when the size and position creates the big boob moments, when normal tasks must be performed differently or even made impossible. I love the fact that Beshine's breasts actually start protruding outward starting at her back, which means that when her arms hang at her sides, they are extending at an angle outward; only when she stands with her shoulders back are her arms allowed to hang straight down behind her boobs. So, as she reaches forward, the increasing back to front arc of her breasts requires her arms to raise higher to the point where, when extended straight forward, they are in all essence, shoulder height. The implications of this are enormous, and as I have said, never experienced if your breasts are lower. CC, though huge, her breasts are measurably lower; her arms raised maybe only 45 degrees compared to Beshine's maybe 80 degrees when resting atop her breasts.
I rarely go into the fantasy zone because that is what it is; fantasy. At some point, the weight becomes too heavy for the skeletal structure. Of course, it breasts could be expanded with something like memory foam, that would be fantastic; nominal weight, huge shape that can defy gravity, be soft, and bouncy.
I like where your minds strays to lactation and breast sensitivity. Some girls experience orgasm through breast play alone and this is only magnified with lactation because it releases oxytocin, which increases euphoria, often to the point of vaginal contractions and orgasms. Of course, if you are lactating, the oxytocin releases your milk, which can have a fountain affect with orgasms. It is rather rare, but it does happen is special girls; one girl told me that she was embarrassed because she could not avoid orgasms when nursing. That said, you worry about loss of sensitivity; with increased natural growth, the tissues and nerves are stretched, and it is normal for the nipples to become less sensitive. And again, lactation tends to reverse this in some cases because it requires increased oxytocin. Still, the image of lying there, huge breasts standing up like Beshine's, and spraying with every orgasm is very intriguing. And in your fantasy world, imagine that, sex causes your breasts to grow, perhaps a ml in volume with each encounter, which increases your sexual desire until your mind is lost, thinking only of sex and bigger breasts, and affectively making you a desperately horny nympho fuck doll, until your breasts reach 50,000ml each and the desire comes under control, but leaves you with enormous breasts. Everyone knows at a glance how they got that big but you don't care; "hey, I'm normal now, but look at my huge boobies." Sacrifices; sometimes they are worth it.
In my humble opinion, I would like to think any girl with dreams of huge breasts would also embrace all the problems they create, each essentially instant affirmation of their own size. I would suggest the ideal size prohibits reaching around your own breasts to touch your nipples, but allows your fingertips to just touch them when reaching over the top. When your breasts are that size, just the act of reaching over them should give you instant pleasure when your fingertips touch your nipples, no play necessary.
But indeed, maintaining a feminine shape is paramount, and the larger the breasts, the increased height of the nipples, if we accept a set bottom point at perhaps the top of the hips and the rounder they become. As I pointed out, Beshine was certainly not spherical when she first got her implants and her nipples were facing more downward; only as she increased her volume did they become round and, at least the left nipple, facing forward at mid breast. There is something great about, even under a few light garments, those tiny nipples still tenting and making their presence obvious.
Beshine certainly does not try to show the big boob moments she experiences and videos are often paused when they are inevitable. Still, she professes a love of experiencing them and I believe that, if your really love huge boobs, each big boob moment (times when your boobs cause something to happen different from normal) should be cherished and actually sought; the more the better as they are a constant reminder of your immense size. Indeed, Beshine's breast size influences everything she does in the course of any day; think about it, everything is affected. And make no mistake, she loves it. Does she love that her breasts make putting on pants more difficult? Not the act, but the reason. Does she like that she has to rest after every 10 minutes when walking. Perhaps not, but you would never know it. Though she drives a big Mercedes SUV so her boobs can fit (they still don't fit within the seat bolsters), she professes that driving may soon not be possible (boobs prevent arm movement for turning), but that does not seem to deter her. There are literally a hundred things she cannot do or has trouble doing, yet, clearly, having even bigger boobs is more important than any of them.
When I look at huge gigantomastia girls, their breasts failing to hold a sexy shape and drooping too far, I feel sorry for them and wish they could opt for a internal bra, not a reduction. I've seen clips of girls in single piece bathing suits, their ball like breast dangling in front of their hips and their chests seemingly void of any protrusion; it is not very sexy. Perhaps they would be if they could actually support breasts the size of morphs or the foam prosthetics we have seen, but unfortunately, that is not reality. In the real world where weight is a real thing, breasts are limited in size by what weight can be reasonably handled. If that weight needs to take on a increasingly rounder shape with growth to remain sexy, feminine, and hourglass, that is the shape that makes the most sense. If boobs are not about having a full chest, what are they about?
Beshine's butt/hips were nearly non-existent before her implants. Though most do not support her striving to have a booty of sorts, I find it sticking out like that to create a more feminine look and it helps create the whole exaggerated top heavy hourglass look. In my humble opinion, so long as she kept a firm waist, she could add another 20 lbs. on her his to smooth out the look. I would have never suggested she fill her lips to create a permanent pucker, but now, there is something very sexy about the look. It is like she wanted to be a exaggerated Lola Ferrari or human sex doll in appearance. I am very certain she likes every change and has proven that with some investment, you can achieve a dream.
I think, if you love huge breasts and love the idea of always having them causing inconveniences, you would have to adopt the Beshine look to a large extent. You want your boobs high on your chest where you have to raise your arms to reach over them; you want them to be protruding on your sides so your arms rest on them when sitting; you want them high and round so that your arms will always be able to hug them; you want to feel their weight on your chest when you lie back; you want them projecting outward, your nipples tenting your blouse; you want them round so that they are much wider than your chest. You want boobs that protrude almost as far as you can reach, boobs that rest on the arms of chairs, boobs that rest on your thighs, covering them to your knees, boobs that are always creating a imbalance if you are not careful, boobs that are always knocking things off counters when you were not aware the things were there, boobs that block your line of sight of the ground for a least 5 feet, boobs that require someone else to tie your shoes or shave your legs, boobs that make you turn at the waist to move them out of the way so you can reach things, boobs that will make you want to rest your plate on top of your cleavage to avoid the long reach, boobs so high that you have to hold your mimosa to the side and turn your head to drink, boobs so big and firm that you never have to wear a bra unless you want to reduce their movement, boobs so huge that you stretch 4x tops and make it look sexy, , boobs so huge and wide that you will angle your shoulders going through doorways, boobs so big that you will be resting your forearms on them to use your phone or get a credit card from your wallet for that M cup bikini that will not even cover your stretched out areolas, boobs so wide you will have trouble closing car doors, boobs projecting so far that when on your hands and knees, they are pressed firmly against the floor, and boobs so huge and wide that when lying in bed in your only position possible, your back, you find that just a slight turn to the side has your sideboob pressing on the sheet, preventing any further turn, but you will appreciate the weight reduction on your chest as well as reducing the wobbling on your chest with every breath. Ok, so you would be Beshine, just with perhaps another 20k in each boob. I hope that is ok.
