I was scared because I thought this was the case of pedophilia, but turns out its not. Btw this is my understanding from reading it once so dont jump me please
Uke is in love with the father and he imagining to be seme's mom, which means he's the father's "wife". At the scene where he masturbate it was him imagining the father, not grown up seme. Conclusion, he turned on from being called mom because for him that sounds like he's married to the father
Also thats why it makes sense why hes not interested or aroused when seme does things to him at first. Its not because seme grew up, but its because nothing fits his delulu as the father's wife
Or a dead play, who knows
