As Lucifer noticed the way Zoe reacted, he knew that he was succeeding in getting under her skin and arousing her even more than before. He didn't want to rush anything, though, and just kept on caressing her ass softly under the water while she moved her thigh on his cock. But when he saw her bite her lip and close her eyes to concentrate, he couldn't help but chuckle and say, "Oh? Are you getting turned on by rubbing against my cock like this? You know, I think you're starting to enjoy this way more than you're letting on."
Upon hearing his teasing voice, Zoe didn't get angry as expected. Rather, she opened her eyes and just stared at him with narrowed eyes while many thoughts were racing in her mind.
