The moans of the three Mermaids echo inside the cellar, leaving the Nagas confused; they have no way to understand what kind of sensations those girls are feeling.
It's as if those three Mermaids have been caught in the crossfire that is the union of Lucien and Naomi's sinful feelings right now.
And while the group of girls doesn't know what to do, the sinful siblings enjoy each other hidden behind one of the little platforms.
"Mm... mm~~!!" Naomi tries to restrain her moans, but they simply escape between the passionate kisses that Lucien gives her.
"Fuck!!" Lucien can't help but curse in his mind because of how erotic Naomi is.
It's not part of his personality to be shy or to hide his lust, especially from girls who are his 'subordinates' now, but the playfulness with Naomi is different from anything he has with his girls, making it a very enjoyable experience.
