The moment she began to feel thick and hot pure mana seeping into her body. Yuina couldn't help but cover her mouth to hide her voice.
"Ugh... it's... Mmmph!"
A slight tingle became a burning sensation. A new type of energy was invading her body, and strangely, she couldn't compare the previous sensation of mana to this new, overwhelming feeling.
'My body feels on fire... what is this feeling, something is expanding my insides.'
Yuina's body arched as the Mana continued to flow into her. She grasped Asmodeus tight, her fingers sinking into his muscle, while she pierced his flesh with her sharp nails. It was as if the new, stronger energy was trying to force the old, weaker one out.
'It hurt... at first, but now...'
Yet the pleasant feeling of the old energy left her body and created a unique pleasure, a pleasant pain that Yuina never experienced before.
