Hi, I was wondering if someone could remind me of a BL name I’ve completely forgotten, I read the BL a couple years ago now, so things are a bit blurry, but I would be so thankful if someone could help me.

Bottom was blond and Top was red headed, I think?
It all takes place on train, at lest up to the part I read.
Bottom was smuggling this pearl/ball thing for money. It started on a train to the place bottom needed to go to, not sure if it was a prison train, but the bottom shared a room with loads of other men(pretty sure it was the cheapest) and the top came into his bed which was separated form the open room/and the rest of the beds with a green/blue curtain, the top jacked of the bottom(against bottoms will) and while doing so the Top stole the bottoms pearl/ball he was smuggling, so later when the bottom find it missing he tries to track the top down to get it back.

I think the train has different trailers/compartments and they go form one end begging the cheapest and for the lowest of men to the other end for more important men with more money, I think.

Bottom wanted to get to the opposite end as that’s where the top was staying, as I think he was most influential/had most money.

The bottom basically gets sold to different men in the train as a sex slave, to try and get to meet the top to get his pearl/ball thing back. So he can get the money for delivering it + so he won’t be in trouble/beat up for not safely transporting it.

He stayed with 2 men and made a deal with them to have sex for info on how to get to meet the top.

He was sold/stole by a very sadistic man who tortured(one sided BDSM) the bottom. I think bottom was muzzled, and had water thrown at him and had stuff done with ice cubes.

Bottom tried to escape form this guy but he was chained up and the door out of the room had bars across it. I can’t really remember how he got out though I think the top came and “rescued” him.

He also had sex with a bunch of men in a lounge type room in the train, and the top showed up after everyone had already had a turn with the bottom. Top said something like the bottom will never get the ball/pear thing back, and that all he had gone through was tops doing.

So sorry of this doesn’t make sense, but if anyone recognises the description, can you please give me the name of the BL? As I suddenly remembered it but can’t remember the name.

Many thanks-Manga xxx
