BACJ-046 - Being trained by my high-priced, cold-hearted maid

I hired Riku as my personal maid for a fortune, but she treats me like trash. Her cold, disdainful gaze makes me hard every single day. I try to get her attention, but she ignores me—except for the occasional tongue-click that drives me wild. When I pay her triple to 'train' me, she does it with such a bored, mechanical expression. Even when she slaps me and calls me garbage after I finish inside her, I can't help but feel like the happiest man alive.
