A man approaches a naive woman from Amamikoshiken Prefecture at a beach and convinces her to change into a new swimsuit inside his Magic Mirror van. She reluctantly agrees, revealing herself in an unfamiliar bikini outfit that accentuates her breasts. As she struggles through the challenge of not touching herself while aroused by the H-spot stimulation, she eventually becomes too sensitive and blushingly orgasms despite trying to hold back. Unable to resist any longer, they have passionate sex right there in the van!
