Obviously, Dia's size is kept both vague and it is mentioned she can shrink/grow, but I was thinking I'd do some math because it seemed like a fun idea. The math is in metric because I think metric is sexy. I understand the saying goes “different stroke for different folks” so please google conversions if you feel like it. Thus I will begin the insane over-analysis that I have dubbed, “The Dia Calculus.”

In chapter 2, Dia is described being able to comfortably thrust into the planet, gripping the gravity holders, the handles of which I imagine to be about 50 cm apart for her. The planet, which we'll assume based on its description is either Earth or an Earth-like planet, must be a bit less than that, probably appearing about 30 cm wide from her perspective.

The average length of an erect penis is about 15 cm or 6 inches (feel free to assume Dia’s proportions are a bit more or less generous, knowing that her penis cannot exceed what for her would be 30 cm or 12 inches length as with her hips pressed tight against the planet it is not described that she penetrates through Earth, which is what she does to a smaller planet in a later chapter.)

Now, the fun part.

Earth averages about 12 756 km in diameter. Simplifying to 12 000 km makes this a bit easier so we’ll do that. Each centimeter for Dia is actually 400km for the people of Earth. Assuming she’s about 175 Bramarii cm tall (again feel free to assume she could be proportioned differently) she would be about 70 000 km tall, about half as tall as Jupiter is wide. Very impressive and personally this is one of my favourite size ranges.

But there’s more!

With a quick search I learned average ejaculation for men contains about 5ml of semen. Now, Dia is a Tera Giantess Alien Futa. Despite the difference in gender and biology from humans to Bramarii, I’ll use 10 Bramarii millilitres (Bml) as the baseline as she likely ejaculates at least double what is average, because of porn logic. If you like to imagine it’s more, this amount is linearly related to the final answer for the volume of her ejaculation, so for example if your assumed amount is double mine simply double my answer. Getting the actual volume involves some unit conversions and knowledge of geometry. Important to recognize is the square-cube law, where when scaling an object, its volume increases by the scaling factor cubed. There are 1000mL in 1L and 1000 L in 1 cubic meter.

Volume, V = 10 Bml = 0.01BL = 0.00001 Bm^3 = 1*10^-5 Bm^3 (scientific notation)

We’ll call the volumetric scaling factor between humans and Bramarii, B, which is the linear scaling cubed. The units are included to show each stage of the multiplication but the final answer is a unitless ratio.

B = [ (400km*1000m/km*100cm/m)/cm) ]^3 = [ 40 000 000 ]^3  Linear Scaling is 40 million to one!

B = 6.4*10^22  Square Cube Law go BRRRRR

Now we return to Volume, substituting in B:

V = (1*10^-5)*(6.4*10^22) m^3

V = 6.4*10^17 m^3 is the ejaculate volume. This number needs context.

First we’ll convert it to cubic kilometers to make the number small enough to stop using scientific notation. There are a billion meters cubed in a cubic kilometer, so we divide by 1*10^9

V = 6.4*10^8 km^3 = 640 000 000 km^3 She ejaculated at least six hundred forty million cubic kilometers of cum.

For reference, the entirety of Earth’s oceans are estimated to have a total volume of 1.335 billion cubic kilometers. The amount of cum calculated is just under half of this. This means that if Dia was very pent up, as she was in the chapter and ends up releasing a little over twice her usual load, she could ejaculate enough semen to fill all of Earth’s oceans in one go. This confirms her ability to glaze entire continents in the later chapters. She would likely be capable of fully submerging smaller planets in a sea of her cum!

I really enjoyed your story! This thought crossed my mind as I was working on my next work and I decided to take the plunge. Hope you found it entertaining.

Love it!

As for an idea, what about Dia finding someone with similar size and values with her and they would interact with whole planets together?

Futa IS nice. :3

Fantastic story just love it.
