Sakura was responsible for motivating Hiruko. Such was a thing she found interesting as motivation wasn't something people lacked. Her own experience said things she worked for were more rewarding for her, but there was also a certain threshold of interest required for her to feel like working for anything. In the case of Hiruko, he'd long since met her basic threshold for amusement but he was far from an easy person to read. Given that little bit of information she wasn't entirely sure what would motivate him into acting, her own physical choices seemed to gain her something, the things she said gained her other things, but nothing seemed to push him over the edge. She explained a bit of herself to him, and had gained a bit more interesting information. According to Hiruko she shouldn't be resting on her laurels at the edge, and should do something. He claimed perhaps she should ask really nicely for what she wanted.
More experiences and more devious... that made Hiruko a greater challenge than someone like Reiji. The problem with Reiji had been getting him to agree, everything else flowed naturally. This had taken quite a bit of time to get an agreement, complete with Hiruko not throwing himself at the girl and then a build up into a more deviant endeavor. "Sou ka... I don't think I ask for things very often. I never really have to..." she mused. It was a lightly novel idea, would it be worth trying. She normally gave directions, made demands and on some rare occasions manipulated people into doing what she wanted. But as her body continued to both vibrate and be wedged into that constant pulse within her loins and anus were far too great for her to continue resisting. Even she knew when her desires were past a normal limit and she had no idea what would happen if she denied herself. She wasn't sure it was something she wanted to find out, considering the burning which she'd felt even vicariously through other people. She understood gratitude, begging and even a few other things, perhaps an odd combination of the three, blackmail was also a pretty reasonable option if Hiruko decided to try and pull a fast one and finish without her. "Hirrun♥!~" she said finally leaning into him once more she'd offer him another rather deliberate set of kisses while wiggling her hips against those wedging motions of his. The ring of her rear, twitching constantly against him as the fluids of her loins dripped against his torso. "If this is really your crawlspace you should definitely cum inside and mark it as yours♥!~" she moaned out while licking his lips. "And you should let me cum so I'll always remember it too!~" she said adding in a bit of cuteness at then end. "Please, Hirrun♥?!~" she asked nicely. That push was a mighty one for her, and the building pressure within her loins wasn't something she wished to deny herself.
