Somehow, Hina's body is more sensitive than before...!? Hina Asakura and her boyfriend, Kyo Tono, work for the same food company. Kyo's busy with work, and they haven't done it, or even kissed, in a long time... Hina wants to help him feel better, so she does her best to support him by making him lunch and going to his house to help him with the chores. One day, folding his clothes, her body responds to his scent, and she can't help but "take matters into her own hands." As soon as she finishes, he gets home from work... and the warm, damp state of her body gives her away! He asks if she was playing with herself while thinking about him, and then... It's been so long since he has looked at her and touched her, Hina can't resist. She feels pleasures like she's never felt before! She tries to hide it... but she can't keep her voice down!
