Driving swiftly in the car, I gently caress Yui's hand as we head toward a rural area with a mixed-gender hot spring. She smiles at me with her wide, innocent eyes and asks, "What's wrong?" I remove her coat and dress, then begin fondling her big tits with my own hands. I make her keep masturbating, but as her soft breathing turns into moans and she's about to climax, I forcefully stop her. Once we arrive at the inn, she quickly changes into a yukata—the sight already arousing me. Watching her undress, the moment we're alone in the room becomes even more intense. I grope her large breasts over the fabric, relentlessly teasing her. In the enclosed space, only the sounds of Yui's voice and my hands groping her tits echo through the room, creating an unforgettable pleasure.
