Drinking Aqua's pee from konosuba would be the freshest, most purest way to drink water. as a goddess of water she has natural purification abilities and even been shown to accidently affects cups of tea that she serves. so I imaging the liquids being stored in her bladder can be "purified" and the fact it's always in in direct physical contact with her, her pee would be in a consistent state of purifying in her. i would use her body as my personal water cooler. drinking that pure, crystal clear water straight from the tap, ready to serve at my beckon call. i would make her drink non-stop so she will always be ready for produce fresh water for me to drink. i would drink from it every day, in the moring when she wakes up, at lunch while i enjoy my meal, in the evening when I'm feeling a little parch. i would just rip off her panties and go to town on ger clit until she climaxes her gallons of life giving, pure holy water. sometimes i might not even drink any water and just watch her squirm with her full bladder of the world's freshest water. if she pees herself it would be just fine since it's not even pee but just water at that point. she wouldn't go a whole hour without feeling the need to pee, and i as her master will only allow her to relieve herself in my mouth
Megumin's cuteness is a miracle of the universe, it behooves you to create as many little megumins as humanly possible.
With back-to-back pregnancies every 10.5 months and assuming she hits menopause around age 51, you could get around 43 births out of her.
Statistically some of those will be twins, with the rate generally increasing with age and height/weight. Using data from https://www.cdc.gov/nchs/products/databriefs/db80.htm you'd get an average twinning rate of 44.1 per 1000 births. It would be on the low side initially, but as her body fat percentage rose from pregnancy it would even out. With those numbers you'd expect to get 2 sets of twins, but if she has a family history of twins that could rise to around 4-5.
If you gave her certain fertility drugs (specifically gonadotropins), that would increase the chances of multiple birth substantially to 3 in 10, with around 5% of those being triplets or more. In that case, you'd expect 13 sets of twins, with one of them potentially being triplets instead.
So you should have 45 children with Megumin if you do it naturally, and 57 children if you use fertility drugs.
I like the physics in Konosuba's scene, but for more than just the booba bouncin though. In Dragon Maid's scene the blur lines make Kobayashi's slap seem like just a whiff and it comes straight down on Illulu's left boob, yet somehow both booba bounce. You just can't convince me that the energy of that whiff was angled towards both booba. On the other hand, Konosuba's just perfects those sorts details. Although it's a bit slower paced compared to Dragon Maid's you can watch Megumin wind back to properly give her slaps power, and Yunyun properly recoiled up and away in accordance. I have to say Dragon Maid's scene just can't compare in this regard
But on the other hand, Illulu's booba flailing takes up half the screen so I'm gonna have to declare this a tie.
