Did he.. put his fingers inside the other peepee? How? Σ( ￣□￣||)

I mean his dck is huge,the mc’s fingers are thin,this is also a type of masturbation some irl men do using their fingers or sexual tools (Urethral sounding) but it’s highly dangerous

I think I need some sleep I read "peepee" as people and thought ml or mc was cheating. (Havent read the manhwa yet) But yes this does happen irl
