Is that a parody of the UBW Saber torture scene?

"Tits down ass up" is an old trope, that Saber happened to be following in that scene.

If we could capture Schicksal's STRONGEST S-rank Valkyrie... Yeah, good luck with that.

Well, I'd first subject her to the tentacle treatment, and then some injections to make her breasts grow even bigger (and start lactating).
