Human sex in a white room, really? This started with a goblin gang-bang in a dungeon. Then we got orc lair gangbang, which was nice but lasted WAAAAAY too long. And now here comes another downgrade. What kind of feedback is Tsuina getting that he's watering down his story this much with each new issue? This stuff should write itself after the plot twist from the end of volume 2. But here we are, YEARS later, and it's all been downhill since.
