"Let it out... No one but us will hear..."
Lillian gave a shaky, but playful smile, "O-oh~? Y-you want to hea—... Mmh~... M-me moan that badly, Mari~...?" She intentionally let one out.
She then moved her lips into Marionette's ear, whispering, "Naughty girl~..."
Marionette's body stiffened and froze, her breath becoming even more ragged. The hand she was using to knead Lillian's breast also froze in place. Sensing this, Lillian continued.
"Y'you're reacting even more than me~... Where did my stoic baby go~?" She cooed, brushing her lips against the Assassin's ear. She then let out a small moan...
"Mmh~... Ah~..." Purely for fun. She continued to do it even more, despite Marionette's hand not moving. "I-it feels good, Mari~... Aren't you going to continue, baby~...?"
Marionette keenly listened to these, breathing raggedly against Lillian's neck, unwilling to leave it. For once, she was too flustered to show her face. Was this what Lillian experienced when she was around her?
