Kira remained still for a while, trying to figure out what was going on here. With his unblinking eyes, he looked at her in a state of shock.
Their lips were still connected, no one between them dared to move. He could feel the softness of her lips. They were so warm compared to his cold ones.
'Why did she kiss me? Is there something wrong with my power? Or maybe she didn't hear me clearly. I asked for her name, not to be kissed by her! Why can't she follow a simple instruction??!'
His mind was so occupied as if he was trying to solve a riddle. And that riddle was none other than Marceline, herself.
Unknowingly, Kira loosened his grip on her shoulders. When he did that, Marceline was able to move her arms.
She raised her hands, anchoring them around Kira's neck. That's the time Marceline started to move, brushing her lips against his lips in a slow but sensual movement.
