I am a single office lady in my late 30s. I work in the office of a small transport company. There are no female truck drivers, and I am the only one in the office, so even at this age, I am quite adored by those around me. This is about a time when I went on a short trip with the men from my workplace. There were three men and only me as the woman. The men were in their 30s to 40s. I left all the planning, including where to go and the inn, to them, and they rented only one room, saying it was to save costs. Although they were the usual friendly people, when I said, 'This is different,' they replied, 'There's nothing we can do about it now,' so I reluctantly complied. Even so, the party was lively, and with alcohol, everything became possible. While I was having fun, my yukata gradually came undone, and it seemed to stimulate everyone who was drunk. I didn't intend to undress, but as I was having fun with everyone, they got carried away, and I was gradually exposed. My yukata was stripped off, my underwear was taken, and I became everyone's prey. I was treated like a toy. They took turns assaulting me. Even though I am not young anymore, the treatment was too harsh. I sobered up and cried, but it didn't matter to the heavily drunk people; it seemed to excite them even more. Still, by morning, I tried to act as if nothing had happened. I woke up earlier than everyone else, changed clothes, and acted normally... Of course, everyone remembered what happened last night. They seemed relieved to see me acting normally. I acted that way to be considerate of everyone... but it backfired... They thought they could do anything to me... I was attacked in the car on the way back. I was stripped in the large wagon car and had sex with each of them again. I think there is an M part of me somewhere... Even after being treated like this, I act as if nothing happened. Since then, I have been individually invited by those men and made to be their partner.
