ps: im not justifying anything just explaining my interpretation
+ i feel like zhenya doesn't even want taekjoo to feel good, at this stage he's only satisfying HIMSELF. i think he even likes inflicting pain on taekjoo based on his psychotic personality.
i agree with the first take this isn't sex, it's assault; an attack

Ok one you all have had sex once yet….you were raped three times big difference.
Two you cannot just jam a dick that big in someone’s ass unless they partake in fisting on a regular basis and even then it would still fucking hurt like hell. Taekjoo isn’t even aroused so there’s a zero percent chance he be able to be penetrated lubeless without tearing.
Three why is this author so gung-ho on making him seems so weak, dumb, and incompetent?
