Scarlett was confused when Lust appeared out of nowhere. Lucien ignored them and focused on Olivia while Lust told Scarlett the rules on how a little pet should behave well.
Olivia was still unconscious. She suffered serious head injuries, which would be really worrying if Lucien couldn't easily heal anything with his ridiculous life mana.
Lucien held her head and forced his tongue into Olivia's mouth. After a few seconds, she woke up, but she was still very confused and tried to move away from Lucien.
Unlike Scarlett, who couldn't move, Olivia tried to get up and out of the bathtub, but Lucien held her tight and continued forcing the kiss for a few more seconds.
Lust had said that Olivia could only ration properly after receiving enough life mana. After two minutes, in a vain struggle, she started to calm down.
