It is annoying as hell, in the beginning it was a bit funny but it gets annoying real quickly. Even if you have nothing else to do, don't read this, unless you really have nothing else to do.
Yuuto(MC) pays debt for a girl and the girl becomes his slave, feels a bit weird but yeah anything is possible. He is looking for conception and does not do it with the girls, understandable but not everytime the author can give this excuse for not doing. Then he meets Beel(a demon girl), she for falls for the MC and they are about to do it after fighting a monster and someone interrupts them, understandable because they were in a dungeon I guess. But then later they are in their room and again they are interrupted. This makes this really annoying. The story shows us a hope that this time is going to loose his virginity but then something goes wrong and he fails.
