Ichiro entered

As Fumiko continued to rock back and forth on Emi's face, Emi heard the sounds of the library door open, interrupting her orgasm. She tried to see who had come in, but Fumiko's ample ass blocked her vision. She heard someone enter, but as she tried to move so that she could see who it was, Fumiko moved with her, pressing down into her face and moaning. She could tell that Fumiko thought this was part of their activities, leaning back and driving Emi's head into the tile floor. It was slightly painful, but also made her wet at the same time.

"Miss Fumiko?" their guest said.

Emi's eyes went wide as she recognized the sound of their visitor's voice. She began to squirm and protest, trying to sit up and stop her son from seeing her as she was, with Fumiko's fingers prying her open and allowing her fluids to drip onto the tile floor, but Fumiko continued to press her weight into Emi, pinning her. As her legs moved, trying to close and hide her womanhood from her youngest son, Fumiko's hands moved off her pussy and pried her legs open, as if she meant to show her off to Ichiro.

"Hello, Ichi," Fumiko replied sensually, desire oozing through each of her words.

Emi heard Ichiro approach, pausing at her feet. Emi continued to protest, but as she did, she became aware of another sensation in the room. She could feel Ichiro's desire growing and then suddenly she knew everything. Relaxing, she heard the whispers in her head even louder than before, and she knew that Ichiro has always had the secret desire of catching her in the stacks engaging in sexual acts with his friends. She knew that he'd engaged in lewd activities with every woman in the gym that either looked like her or had a connection to her. She knew that Ichiro has fantasies about her doing the sluttiest things he could imagine, and it had all begun when his friends had discovered that there was a time in her life that she'd met up with men for clandestine meetings at love hotels.

"Is this what I think it is?" Ichiro asked, his voice becoming dominant and oozing with recognition.

"It is," Fumiko answered.

"So she found the book?" Ichiro asked.

"She did," Fumiko admitted. "And it is going much better than we imagined."

Emi's eyes went wide as Fumiko rocked her hips gently, but Emi barely noticed. The whispers were showing her something, showing her Ichiro and Fumiko's sins. She say them at the gym where Ichiro worked as a personal trainer, talking and laughing. She saw Fumiko on her knees in the locker room, taking Ichiro's cock in her mouth as she talked about spying on his mother in the bath. She saw Fumiko discovering the book with the inscription at an estate sale and bringing it to Ichiro, the both of them clearly engaging in conspiratorial talk. And finally, she witnessed Fumiko wrapping the book in old newspaper and binding it with rough twine.

As she came back to the present, Emi realized that Fumiko was gyrating her hips again, grinding Emi's head into the floor. Fumiko's slit was so much wetter than before, and Emi knew this was because of Ichiro's presence. This was their fantasy coming to fruition, after all, and Emi knew that her son was also responding likewise. She couldn't see him, but she could discern that he was hard and contemplating how to proceed.

"So," Fumiko asked, her voice still dripping with desire, "which hole do you want? One of mine, or one of your..." after a long pause, Emi heard Fumiko sigh as she said the last word, "mother's?"
