Natsu-chan appears with a bright, energetic voice saying, "Huh? You mean I'm wearing underwear?" True to her name, she radiates a vibrant summer vibe. Her smooth, glowing skin shines through her slightly translucent clothing as she shyly enters, looking youthful and fresh. Once her cute outfit comes off, her well-proportioned breasts and porcelain-white skin are beautifully revealed. She wears a T-back panty that accentuates her plump, firm buttocks. Her sensitivity is incredible—just a light touch of the vibrator makes her go completely limp. During cunnilingus, she gasps, "This feels like nothing I've ever experienced before... What is this...?" overwhelmed by indescribable pleasure. Her breasts twitch with arousal, clearly showing how good she feels. When she starts licking the penis with her small, adorable mouth, it quickly becomes fully erect. She takes it deep inside, repeatedly moaning, "It feels so good!" Her pale skin turns flushed red as she reaches climax after climax, delivering a heat as intense as the end of summer itself. Her powerful orgasms and overflowing wetness are so extreme that the penis slips out, stunned by her intensity. This is truly the ultimate scene symbolizing summer's end!
