The sudden appearance of a glimpse of cleavage when you bend over. Situations like cafes, tutoring, and massage parlors where 'cleavage slips' happen. The dilemma of 'can see but can't see' is unbearable. Even if you're usually too shy to look directly, you can stare at the suddenly exposed cleavage all you want! “S-Stop it…” At first, Keiko is confused, but gradually she starts shaking her beautiful breasts and gasps with a blissful expression! Enjoy the beautifully trembling breasts through the gaps in her clothes as they are thrust vigorously.
