An amusing bit of context for this set - aside from 19-20, every monster here is actually the *same* monster, flexing its stolen divinity (gained from being the critter that managed to rape the valkyrie first (21-25)) to mess around with shapeshifting and with splitting itself into multiple selves at once.
The orange-haired princess was trying to summon a valkyrie to save her kingdom, only to summon one mid-tentacle rape (17-18). Resulting in pretty much every part of this set involving the princess.
I guess this is another set where gallery order is completely separate from story order. The work cold-opens with 17-18, 19-31 are the monster subjugating the valkyrie before their dual summoning, 3 to 15 are the monster subjugating the princess (while continuing to fuck the valkyrie offscreen), 33 to 45 are basically the monster's victory lap with both girls. With 39-45 being public displays in the princess's now-conquered city.
