And though he has such an assuming face, it turns out that in reality he’s a vigorously curious person and maybe a hidden sadist...? Ema with her hidden desires, Rei with his need to expose those that are deeper... “I want you to understand that you are now mine.” Shlick, shlick as he pounds into her, cumming instantly as she is restrained during sex... Ema feels both her mind and body being satisfied. At home, at the office, outside... will Rei’s way of loving her continue to escalate...!?
