"Ar-Are you okay?" Leo couldn't help but ask her after seeing her expression, even stuttering in the beginning.
Lia gritted her teeth and nodded her head in a stiff manner.
"Okay, but if it hurts, you must let me know, alright? I don't want to be executed for accidentally hurting you…" he said in a low voice.
Over the next several minutes, Leo would quietly absorb Lia's mana. The more he used Mana Drain the better he got at controlling the amount of mana he absorbed from Lia.
However, Lia was anything but quiet, as she would occasionally let out a cute moan that would tickle Leo's heart whenever he heard it, and it became more frequent the longer they did it, almost as though Lia was slowly letting go of her restraints.
Leo eventually couldn't handle her moaning any more and stopped absorbing her mana.
"Alright, we can stop here. I think I have enough experience with Mana Drain."
