In this story, Mitsuki Nagisa, a college student on the track team at a university, has been secretly desiring sexual pleasure due to her long-distance relationship with her boyfriend attending another school. Despite being popular among men at her own university, she remains loyal to him. However, recent encounters through dating apps have left her feeling increasingly frustrated. She tries not to cheat but finds herself tempted by the attention she receives. One day, two incubi named Alt and Uno appear before her after an encounter with a mysterious girl. They tease her about losing consciousness during intense pleasure and even suggest that she might be experiencing an orgasm for the first time. The camera captures POV shots, making it feel like the viewer is experiencing everything alongside Mitsuki - the touches, the sensation of being penetrated, and the overwhelming heat. As she becomes more aroused, she wonders if what she's feeling could possibly be related to dream sex or some other phenomenon. By the end of the scene, Mitsuki finds herself soaking wet and questioning whether what she experienced was just a dream or something else entirely.
