The data does not reflect the story portion, so it is hard to tell....
Basically, for task1 and task2, it is recommended to give a slow massage anyway.
Depending on the remaining HP, if you start insertion when the two HEAT symbols become brighter, I think you will be able to fertilize the queen while reducing the decrease in her strength.
Incidentally, at the beginning of the unreflected story, Aure explains to us that we should make the queen feel good, and that we should not be in a hurry and increase the HEAT first.
He also explains “never put it in the anus”.
(In case you are wondering, this is planned to be a post-clearance content...)
As for the hand and tongue action, I would like to add just a little more.
