Wait what?
They didn't get interrupted, no protagonist misunderstanding what her fullfilling the contract meant, no suddenly falling asleep, no guy falling asleep while the girl does all the job, no fade to black after multiple pages of internal dialogues on a white background, no premature ejaculation, no ED, no size problems, no stopping halfway, no time wasted on preliminaries, no character having a sudden change of heart, no panic attacks.
All in less than 50 chapters.
Did the author had to make a deal with the devil to get this greenlit?
edit: also once again proving that you don't need to show genitals to make a good scene like this.
