he could escape, but he felt he had nowhere to go and he wish to stand by and repay the seme, his savior.Then, he was protecting kyouta and the seme. He was pressured

That's right, the fat guy rapist threatened him with going after the seme, so uke submitted in order to protect the seme from the fat guy. And fat guy was probably from the yakuza or someone very powerful, even if any of the bodyguards would've been able to overcome him physically, evidently he had some other type of hold over them.

PROTRECTING??? MY ASS THE UKE WANTED TO GET RAPE TOO.
It's not often I read something and dismiss it as pure bollocks...But that was utter wank. And plot, what plot?!
The most disturbing thing about it is that the Uke was willingly with that guy, he was not under duress. He had the power to say no, but he liked fantasising about his colleague too much so went along with it and willingly took those drugs and went with that guy willingly to his room again and a-bloody-gain.
Then ah, yeah OK - the 'hero' seme wanted to have sloppy seconds sex with him right after he had 'been raped' by the fat old dude and still had his come in his ass? Where is even the attempt at portraying realistic human psychology here?!?!?!?!?! This is one of the worst Yaoi I've ever read, and I've read some utter shite in my time!
Nah son, rubbish.
