No mercy. Reisen wasn't even smiling nor was her face flushed. She was like her Master, ruthlessly handing out punishment. And it was no joke, she pushed Reimu to a climax as fast as she could, to deny her the pleasure and love that came from taking her time. While giving her this unique form of torment, her eyes never left Reimu's face, watching it closely and savoring every moment possible. This was really a super serious Reisen that the shrine maiden had probable never seen.
