It seemed for a moment that Sakura was about to hear this supposed bragging of Kakihara's, but... it was silenced before it began properly. For humans to be creatures of privacy and secrecy, this one seemed to enjoy talking about things a strange amount. More than that, Sakura honestly thought he was way too excited given what had happened, if she'd had to describe it, she would have claimed the session was good, and scratched a certain itch she needed scratched at a time. But she would have also prefaced her desire to use others for the task, even Saika was a better choice in general. Reiji was planning to add this particular purchase to Kakihara's tab, as if he wanted to get rid of his quickly. He'd also silenced the lad's story, which was intriguing, Sakura figured it was part of his propriety to not partake in the tales that he would have offered. It was probably also for the best, as this was currently the best time Sakura had so far, and she was trying to not have to rewind the area around Reiji too many times more.
Admittedly, she was being a bit devious, but she felt like a little sneakiness would add to the moment a bit and help him with his decision making. Yes, that was the way to think about it. She'd had a certain reaction when she felt that man's cock hardening beneath her hand. A wicked grin spread across her face as she realized what had actually happened. What was more, he was now leaning down towards her looking for a particular briefcase. But he was also saying something about his knees and being old. Sakura had a pretty good idea of his physique given her proximity and she was certain... 'There is nothing wrong with Reiji-san's knees.' she said. With that gesture already made and having done its job she poked those knees and found herself looking at the man's face. She figured she could do her part to help him, and shuffle a briefcase or two forward while not revealing her own location.
