Nervous yet tipsy, Mai Arisu meets her admired senior, Yui Hatano, in a cozy, slightly drunken atmosphere. Yui offers her a sip of beer mouth-to-mouth from a beer mug, moving Mai so deeply that she bursts into tears of emotion and excitement. Touched by her sincerity, Yui whispers, "Let's get naked together ♪" and gently draws her into the world of lesbian pleasure. Sitting side by side on the sofa, they begin masturbating in front of each other, their wet cunts squishing softly as their intimacy grows. They kiss passionately, unable to pull away, their lips melting together as alcohol and desire blur into one. Wanting to grow even closer, they head to a special izakaya and order the most expensive pink champagne on the menu, their faces and chests flushing red with intoxication as they enjoy each other's company. Mai buries her face into Yui's ample breasts, cuddling and giggling like a happy child. When Yui is touched on her clit through her panties, she climaxes instantly. Mai stares intently at Yui's wide-open pussy, hesitantly inserting her fingers and carefully thrusting while watching Yui's reactions. She licks her clit with a soft tongue, bringing her to orgasm again and again. When Yui licks her ears, Mai shivers with ticklish pleasure, writhing uncontrollably. As Mai begins moaning helplessly, Yui gently wraps her arms around her, licking and caressing every inch of her body. This is Mai's first time exploring a woman's body, and she completely surrenders herself to her senpai, sinking deeply into the pleasures of lesbian sex. Also included is a special making-of, exclusive to digital release, showing behind-the-scenes footage. Even the nervous Mai quickly relaxes and breaks into smiles under Yui Hatano's gentle touch. As the scenes progress, their bond deepens—until finally, they confess, "I think I've fallen for you."
