Emi and Fumiko cum while Ichiro watches

As Fumiko's fingers worked her opening and her clit, Emi came hard, feeling the crackling energy pass through her again. It was a softer feeling that before, but it rolled over body for a long time, causing her back to arch and her hips to buckle. Her fingers curled into claws on Fumiko's hips as the feeling rolled outward from the center of her body, reaching down to her toes and up to her head simultaneously. Wave after wave crashed over her, writhe and moan on the floor.

She knew that Ichiro was nearby, watching his mother orgasm, and that thought alone emphasized everything that was happening. Part of her wondered if, like she, Ichiro was forming a core memory based on her having an orgasm while he was in her presence. She knew that it was something he'd always wanted to see, and so she knew he would also never forget this experience.

As Emi thought about her son watching her cum, Fumiko hips clenched. Emi could feel her coworker's thighs crushing her head, and it was a welcome feeling. She also heard the muffled sounds of her lover's orgasmic moans, aimed in a particular direction, which she assumed is where Ichiro was watching them. Extra fluids leaked out of Fumiko's pussy, dripping down onto Emi's face as she quivered and shook through her orgasm. She felt Fumiko's hands grip her hard, causing additional shockwaves to accompany her pleasure waves.

"That is amazing," Emi heard Ichiro say, and somewhere deep in her understanding, she knew that he was stroking himself at the sight.

As their mutual orgasms began to die down, their muscles relaxing, Emi realized that she loved the way Fumiko came. But as her mind cleared, she realized that she could no longer sense Fumiko or Ichiro's thoughts. Things had changed and Emi was feeling more like her old self, albeit covered in Fumiko's juices.

As Fumiko climbed off of Emi, she turned to look at her. For a brief moment, Emi thought she saw that symbol from the book in Fumiko's eyes, but it was gone a moment later. Turning to Ichiro, she saw him standing there, his cock in his hand, with a mischievous grin on his face.

Sitting up, Emi looked for the book she'd dropped on the floor, the one that had whispered secrets to her. She found that it was still open to the title page, but the inscription and the symbol were gone. There was no writing in the cover and instead, she found herself looking at a regular, first edition copy of “Nami-ko” by Rouka Tokutomi.

“It seems that the symbol didn't stick with her," Fumiko said to Ichiro.

"Symbol?" Emi asked.

"Don't worry about it, Mother," Ichiro replied. "Why don't you just get dressed and we'll talk about this later."

As she dressed in silence, keeping her back to son, she knew that when they left the library and returned to the world, there would always be something different between the three of them. But something about the situation didn't bother her, and she knew that when they called upon her again, she wouldn't need the whispers of the book to do whatever they wanted.
