To be honest this is kind of sad. Yu didn't like that at all but felt inclined to keep on going for takamada's sake. I would have preferred it if it they went back to the previous arc where they were exploring different sexual plays together and were both enjoying it.
That's interesting, I saw it in another way. I mean he never said/thought literally that he didn't like it, did he? He said it was kind of too much stimulation and it was getting hard to handle for him No one got hurt or upset in the end, it's just that he got a bit overwhelmed in my opinion
