When Eri-chan's neck is touched, she shows a slightly sensitive reaction. But as the stimulation intensifies, she gradually can't hold back anymore and bursts into loud laughter, "Ahaha!" Even while squirming, ticklishness and pleasure alternate, and her reactions grow bigger and bigger. When the electric massager and vibrator stimulation are tried, her voice becomes unstoppable and she looks overwhelmed. Eri-chan, who keeps laughing to the end while thrusting the vibrator into her pussy, is quite captivating.
