Which of the Gorgon sisters had the most delicious ___?
Stheno and Euryale ultimately lost.
If they faced him alone, they simply could not win. In the end, their side was the first to experience a descent, and the sheath was the first to have a stress reaction.
So, he allowed the two of them to fight together.
And he had proposed this wager.
If they won this time, he would consume the substance ultimately extracted from their side.
Conversely, if they lost, they would consume what he extracted.
And they would enjoy it right in front of their adorable little sister.
Thus, the already heated-up sisters, thoroughly provoked as they were, naturally refused to lose like this. They wanted to win it back.
Making him fulfill that agreement and use the substance they provided was, in their eyes, a humiliating punishment. Naturally, they dearly wanted him to receive such punishment.
Although consuming a substance they had produced was rather subtle, it would be fine if they could humiliate him.
In the end, both sides suffered losses—because it was a draw.
So, both sides had to use what the other provided.
Thus, when their adorable younger sister entered, they took the already extracted substance stored in containers and poured it into cups.
Incidentally, their contest with him had taken place in the mental world.
After returning to reality, they compressed the sensations produced in the mental world into one second of reality. The sensations were so unforgettable that neither of them could forget how terribly they had behaved.
Once they had poured it, they handed it to him, while his was handed to the sisters.
Right before their little sister Medusa's wide-eyed gaze, they consumed them in front of her.
So why had their little sister Medusa widened her eyes?
