I was standing there along with 250 other couples and was getting undressed as cameramen roamed the floor filming every detail.
This had all started with a visit to a friend I had made in Japan. On an earlier business/vacation trip a woman, Miko, had introduced herself as wanting to practice her English and had joined me in touring Tokyo and the surrounding areas. At the end of our third day together we were on our way to a bathhouse and it was when we were walking down an empty road leading to the bathhouse that both Miko and I had our skirts and panties tugged down to our ankles by a hooded stranger. So there we were with our butts exposed. We quickly pulled our panties and skirts up and were in shock.
Once I had gotten over the shock of this my second shock was the bathhouse itself; it was not segregated. So there I was first being touched and showered by a female attendant and this all in full view of men who were likewise being attended to by male attendants. The bath in this case consisted of squatting naked on a small stool while the attendant first lathered me up and then rinsed me off. It was required of every bather before entering the hot soaking pools. In the pools Miko introduced me to other men and women who were her friends and were very curious about me, an American Asian.
I am of Vietnamese descent. So both the ladies and men had me stand up for examination and an intimate one at that. They wanted to see if my body differed from a Japanese woman's body and did my hair feel different. I am short like many Asian women, have jet black, coarse, straight hair, dark eyes, a slightly tanned or yellow skin, with a slightly more rounded butt than many of the Japanese women. My pubic hair which both the men and women saw no problem with touching is also coarse and straight like many Asian women's hair. I had it trimmed into a two-inch wide landing strip on my belly and kept my labia free of hair. My trimmed hair patch and my exposed clitoris, labia and nymphae were of great interest to both the men and women; almost all the Japanese women did not shave. Their genitals were covered in differing patches of dark hair.
On top of their curiosity in my physical difference, the men and women also felt no problem with sitting against me skin-to-skin or standing in front of me with their penises or crotches only inches from my face. Social distance was null.
Unknown to me Miko had planned the depantsing, the having an attendant running her hands all over my naked body and I do mean even in my intimate places, and being felt up and rubbed against by her friends in the tubs... all with the intention of getting me aroused. She further loosened me up with some local rice wine. The heat of the pools' waters soon had the alcohol coursing through my head, but also making me feel hornier.
This all led up to the final act on the local subway. Miko had sensed that I was feeling adventurous away from my husband and my children and thought she had chosen the right woman for what was about to happen. She knew of a crew of men who would find women randomly on the trains of Tokyo and elsewhere, strip them, sexually toy with them until they experienced an orgasm or multiple orgasms, and then engage them in oral sex and intercourse. They would film the entire episode and post it as amateur pornography. To make the films more erotic and less like assault Miko was one of several women these men used to determine how receptive a woman was to an adventurous sexual experience.
I was tipsy so I trusted Miko to direct me to the proper train; she even picked the particular and end of the car. At the time I was too woozy to see how deliberate she had been. She even told me which direction to turn when I entered the car so that I found myself on one of the ends of that car. I didn't notice at the time I boarded that the screens on the windows of this end of the car had been drawn closed.
At first nothing happened. Bodies pressed against me, but this was nothing unusual for a train in the crowded conditions of Tokyo. The bodies pressed so much against me that I actually dozed off in my drunken sleepiness standing up and held up by the press of bodies against me. It was nothing in Japan to feel a man's erection because he was pressed against your feminine body.
