okay ... the daily lesson is: do you want to play with the feelings of others? All right, wait until sooner or later what you have scattered on the street is returned with interest - interest worthy of usurers, of course, otherwise the game would not be very constructive.
Second lesson (important): it would always be appropriate for the lessons to come from people who are whole and worthy of being able to impart them. Are we really sure that Naru is this kind of person? Because I'm not convinced at all, but for a while I give him the benefit of the doubt.
Let me understand, what does he like about senpai, apart from the physicality? Zero expressiveness, it's practically always bored. He asked him to make him a blowjob (tact or delicacy equal to less zero) and he also thinks to apologize because he is not capable? I like this uke, I feel a great tenderness for him, but at the same time it also annoys me. Regarding the seme, for now I don't classify it. I only see that he is making fun of a very shy and completely inexperienced guy and I don't like it.
However, history is at the beginning, there is hope that he will change.
