Ah, yeah, maybe.
Limitations of the space I guess. We flirted with showing a shot under water, but there's technical hindrances. The whole head in a water and size of the bathroom constrained the framing options, although what is presented is pretty erotic in my opinion. The face down ass up profile shot where you get a good view of the lines of her body, the one where her tits is scrapping the water and you see her get dunked, the finale where Kat's head is unceremoniously off screen, ass bouncing, like she's not even a person. There's a certain appeal there.
I get it it though, some people want to see tits, but it's not like the scene was lacking in that department.
