A salaryman sneaks into a popular private-room massage parlor. Deliberately wearing tight bikini panties, he receives a massage, first lying face down as the masseuse carefully works on his back and shoulders. In the second half, lying on his back, his hard erect cock visibly bulges and protrudes from the tight bikini, exposed right in front of the masseuse. As he flaunts it, watch closely how she reacts. What will be the final outcome of their encounter?
