Eri-chan starts off looking a bit sensitive as her neck is touched. However, as the stimulation intensifies, she gradually can't hold back and bursts into loud laughter with "Ahaha!" While squirming, sensations of ticklishness and pleasure alternate, and her reactions grow bigger and bigger. When she's tested with a vibrator and a dildo to see how she responds, her voice becomes unstoppable. The sight of Eri-chan laughing all the way while thrusting a dildo into her pussy looks quite captivating.
